Interdisciplinary ICU Cardiac Arrest Debriefing Improves Survival Outcomes
Abstract
In-hospital cardiac arrest is an important public health problem. High-quality resuscitation improves survival but is difficult to achieve. Our objective is to evaluate the effectiveness of a novel, interdisciplinary, postevent quantitative debriefing program to improve survival outcomes after in-hospital pediatric chest compression events.
Single-center prospective interventional study of children who received chest compressions between December 2008 and June 2012 in the ICU.
Structured, quantitative, audiovisual, interdisciplinary debriefing of chest compression events with front-line providers.
Primary outcome was survival to hospital discharge. Secondary outcomes included survival of event (return of spontaneous circulation for ≥ 20 min) and favorable neurologic outcome. Primary resuscitation quality outcome was a composite variable, termed "excellent cardiopulmonary resuscitation," prospectively defined as a chest compression depth ≥ 38 mm, rate ≥ 100/min, ≤ 10% of chest compressions with leaning, and a chest compression fraction > 90% during a given 30-second epoch. Quantitative data were available only for patients who are 8 years old or older. There were 119 chest compression events (60 control and 59 interventional). The intervention was associated with a trend toward improved survival to hospital discharge on both univariate analysis (52% vs 33%, p = 0.054) and after controlling for confounders (adjusted odds ratio, 2.5; 95% CI, 0.91-6.8; p = 0.075), and it significantly increased survival with favorable neurologic outcome on both univariate (50% vs 29%, p = 0.036) and multivariable analyses (adjusted odds ratio, 2.75; 95% CI, 1.01-7.5; p = 0.047). Cardiopulmonary resuscitation epochs for patients who are 8 years old or older during the debriefing period were 5.6 times more likely to meet targets of excellent cardiopulmonary resuscitation (95% CI, 2.9-10.6; p < 0.01).
Implementation of an interdisciplinary, postevent quantitative debriefing program was significantly associated with improved cardiopulmonary resuscitation quality and survival with favorable neurologic outcome.
... Despite following these guidelines, research suggests that CPR quality remains suboptimal with poor outcomes in many hospitals [6,7]. Over the past few decades, various quality improvement (QI) interventions have been implemented and individually assessed for optimizing CPR performances and reducing mortality rates [8,9]. However, the data are still limited. ...
... However, the data are still limited. Debriefng after CPR events has been associated with improved quality of CPR and survival after IHCA [9]. It ofers an opportunity to identify and address the critical event comprehensively improving the overall resuscitation team performance [9]. ...
... Debriefng after CPR events has been associated with improved quality of CPR and survival after IHCA [9]. It ofers an opportunity to identify and address the critical event comprehensively improving the overall resuscitation team performance [9]. We aimed to assess the efectiveness of a qualitative improvement (QI) bundle (hands-on training and debriefng) on compliance with AHA resuscitation guidelines during IHCA in our children's hospital. ...
Introduction:
Various quality improvement (QI) interventions have been individually assessed for the quality of cardiopulmonary resuscitation (CPR). We aimed to assess the QI bundle (hands-on training and debriefing) for the quality of CPR in our children's hospital. We hypothesized that the QI bundle improves the quality of CPR in hospitalized children.
Methods:
We initiated a QI bundle (hands-on training and debriefing) in August 2017. We conducted a before-after analysis comparing the CPR quality during July 2013-May 2017 (before) and January 2018-December 2020 (after). We collected data from the critical events logbook on CPR duration, chest compressions (CC) rate, ventilation rate (VR), the timing of first dose of epinephrine, blood pressure (BP), end-tidal CO2 (EtCO2), and vital signs monitoring during CPR. We performed univariate analysis and presented data as the median interquartile range (IQR) and in percentage as appropriate.
Results:
We compared data from 58 CPR events versus 41 CPR events before and after QI bundle implementation, respectively. The median (IQR) CPR duration for the pre- and post-QI bundle was 5 (1-13) minutes and 3 minutes (1.25-10), and the timing of the first dose of epinephrine was 2 (1-2) minutes and 2 minutes (1-5), respectively. We observed an improvement in compliance with the CC rate (100-120 per minute) from 72% events before versus 100% events after QI bundle implementation (p=0.0009). Similarly, there was a decrease in CC interruptions and hyperventilation rates from 100% to 50% (p=0.016) and 100% vs. 63% (p=<0.0001) events before vs. after QI bundle implementation, respectively. We also observed improvement in BP monitoring from 36% before versus 60% after QI bundle (p=0.014).
Conclusion:
Our QI bundle (hands-on training and debriefing) was associated with improved compliance with high-quality CPR in children.
... Providing adult learners with meaningful feedback is likely to be an important contributor to improved future performance [1][2][3]. Debriefing following simulation-based medical education (SBME) events is a key step in allowing participants to identify performance gaps and sustain good practice [3][4][5]. To achieve this goal, it is acknowledged that effective debriefing is important [6,7]. ...
... Notably, the current debriefing literature does not extensively report on using such quantitative data for debriefer feedback. There is a precedent for using a datadriven approach to feedback in healthcare more broadly [2,15,16]. Studies of data-driven feedback for healthcare providers showed improved team performance and this approach has been evaluated in both the social science and sporting literature [15][16][17][18][19]. ...
... This is an encouraging finding. While it does not guarantee translation into better debriefing, in other settings data-driven feedback has been shown to significantly improve performance [2,23]. This study was interrupted by the recent COVID-19 pandemic leading to an under-recruitment of debriefings (n = 12), yet we were still able to observe a broad range of interdisciplinary simulation participants and 7 debriefers across 2 SBME sites (Table 1). ...
Background
Debriefing is an essential skill for simulation educators and feedback for debriefers is recognised as important in progression to mastery. Existing assessment tools, such as the Debriefing Assessment for Simulation in Healthcare (DASH), may assist in rating performance but their utility is limited by subjectivity and complexity. Use of quantitative data measurements for feedback has been shown to improve performance of clinicians but has not been studied as a focus for debriefer feedback.
Methods
A multi-centre sample of interdisciplinary debriefings was observed. Total debriefing time, length of individual contributions and demographics were recorded. DASH scores from simulation participants, debriefers and supervising faculty were collected after each event. Conversational diagrams were drawn in real-time by supervising faculty using an approach described by Dieckmann. For each debriefing, the data points listed above were compiled on a single page and then used as a focus for feedback to the debriefer.
Results
Twelve debriefings were included (µ = 6.5 simulation participants per event). Debriefers receiving feedback from supervising faculty were physicians or nurses with a range of experience ( n = 7). In 9/12 cases the ratio of debriefer to simulation participant contribution length was ≧ 1:1. The diagrams for these debriefings typically resembled a fan-shape. Debriefings ( n = 3) with a ratio < 1:1 received higher DASH ratings compared with the ≧ 1:1 group ( p = 0.038). These debriefings generated star-shaped diagrams. Debriefer self-rated DASH scores (µ = 5.08/7.0) were lower than simulation participant scores (µ = 6.50/7.0). The differences reached statistical significance for all 6 DASH elements. Debriefers evaluated the ‘usefulness’ of feedback and rated it ‘highly’ (µ= 4.6/5).
Conclusion
Basic quantitative data measures collected during debriefings may represent a useful focus for immediate debriefer feedback in a healthcare simulation setting.
... [1][2][3][4][5] Provision of high quality, guideline-compliant CPR improves hemodynamics and is directly associated with improved patient outcomes. [6][7][8][9][10][11][12] Despite the proven importance of high-quality CPR, trained healthcare providers have consistently demonstrated an inability to perform effective chest compressions (CC) in both simulated and real CPA. [13][14][15][16][17][18][19][20] In a series of studies from a single institution, Sutton et al. describe how pediatric providers struggle to deliver guidelinecompliant CPR during pediatric CPA. ...
... 20 The use of two interventions, real-time CPR feedback during CPA, and Just-in-Time (JIT) training (with real-time CPR feedback during practice), have demonstrated improved quality of CPR during practice, 19,21,22 simulated CPA 18,20,23,24 and real pediatric CPA. 11,12,16,17,23,24 Despite the growing body of supportive evidence, no studies to date have described the variability in the impact of these 2 interventions on quality of CPR across multiple pediatric institutions. Variable impact of these interventions across institutions may indicate the need for implementation strategies that are tailored to the pattern of performance deficits identified amongst individuals or within specific institutions. ...
Aim: The variability in quality of CPR provided during cardiac arrest across pediatric institutions is unknown. We aimed to describe the degree of variability in the quality of CPR across 9 pediatric institutions , and determine if variability across sites would be affected by Just-in-Time CPR training and/or visual feedback during simulated cardiac arrest. Methods: We conducted secondary analyses of data collected from a prospective, multi-center trial. Participants were equally randomized to either: (1) No intervention; (2) Real-time CPR visual feedback during cardiac arrest or (3) Just-in-Time CPR training. We report the variability in median chest compression depth and rate across institutions, and the variability in the proportion of 30-s epochs of CPR meeting 2010 American Heart Association guidelines for depth and rate. Abbreviations: ACLS, advanced cardiac life support; AHA, American Heart Association; BLS, basic life support; CPA, cardiopulmonary arrest; CPR, cardiopulmonary resuscitation; CC, chest compressions; CCF, chest compression fraction; JIT, Just-in-Time; PALS, pediatric advanced life support. ଝ A Spanish translated version of the summary of this article appears as Appendix in the final online version at http://dx. Results: We analyzed data from 528 epochs in the no intervention group, 552 epochs in the visual feedback group, and 525 epochs in the JIT training group. In the no intervention group, compression depth (median range 22.2-39.2 mm) and rate (median range 116.0-147.6 min −1) demonstrated significant variability between study sites (p < 0.001). The proportion of compressions with adequate depth (0-11.5%) and rate (0-60.5%) also varied significantly across sites (p < 0.001). The variability in compression depth and rate persisted despite use of real-time visual feedback or JIT training (p < 0.001). Conclusion: The quality of CPR across multiple pediatric institutions is variable. Variability in CPR quality across institutions persists even with the implementation of a Just-in-Time training session and visual feedback for CPR quality during simulated cardiac arrest.
... CPR quality metrics, time to defibrillation) collected during the cardiac arrest event have been associated with improved survival outcomes from pediatric cardiac arrest. 16,17 Unfortunately, postevent debriefings are infrequently conducted in most institutions, and when conducted, objective data is rarely used to support these conversations. 18,19 As a result, resuscitations teams are forced to rely upon provider recall of resuscitation events, which is often flawed and inaccurate, 20,21 to frame their discussions during debriefings. ...
... Compared to control group, the time to critical interventions metrics in the data-informed debriefing group were decreased, but the differences were not statistically significant for time to initiate CPR (control vs intervention: 16 Table 3). ...
Aim:
To determine if data-informed debriefing, compared to a traditional debriefing, improves the process of care provided by healthcare teams during a simulated pediatric cardiac arrest.
Methods:
We conducted a prospective, randomized trial. Participants were randomized to a traditional debriefing or a data-informed debriefing supported by a debriefing tool. Participant teams managed a 10-minute cardiac arrest simulation case, followed by a debriefing (i.e. traditional or data-informed), and then a second cardiac arrest case. The primary outcome was the percentage of overall excellent CPR. The secondary outcomes were compliance with AHA guidelines for depth and rate, chest compression (CC) fraction, peri-shock pause duration, and time to critical interventions.
Results:
A total of 21 teams (84 participants) were enrolled, with data from 20 teams (80 participants) analyzed. The data-informed debriefing group was significantly better in percentage of overall excellent CPR (control vs intervention: 53.8% vs 78.7%; MD 24.9%, 95%CI: 5.4 to 44.4%, p = 0.02), guideline-compliant depth (control vs. intervention: 60.4% vs 85.8%, MD 25.4%, 95%CI: 5.5 to 45.3%, p = 0.02), CC fraction (control vs intervention: 88.6% vs 92.6, MD 4.0%, 95%CI: 0.5 to 7.4%, p = 0.03), and peri-shock pause duration (control vs intervention: 5.8 s vs 3.7 s, MD -2.1 s, 95%CI: -3.5 to -0.8 s, p = 0.004) compared to the control group. There was no significant difference in time to critical interventions between groups.
Conclusion:
When compared with traditional debriefing, data-informed debriefing improves CPR quality and reduces pauses in CPR during simulated cardiac arrest, with no improvement in time to critical interventions.

... Debriefing is recommended by the American Heart Association [4] and associated with improved patient care [5]. This study showed health care worker support for debriefing clinical events in the emergency department. ...
Background:
Debriefing is increasingly used in clinical environments. Surveys indicate staff support for debriefing clinical events, but little is known about the specific effects of debriefing on healthcare workers in the workplace. INFO (Immediate, Not for personal assessment, Fast facilitated feedback, and Opportunity to support and ask questions) is a charge nurse facilitated clinical event debriefing program implemented in 2016 and currently used in five Emergency Departments (ED) in Calgary, Alberta, Canada. There have been more than 840 documented INFO debriefings.
Methods:
Thirty interprofessional ED healthcare workers were recruited through posters and email to take part in voluntary one-on-one interviews using a standardized question script that asked participants about their experience with INFO debriefing assessments. Specifically, participants were asked to provide demographic information, give feedback about their involvement in INFO clinical debriefings, impact of debriefings on their clinical practice, stress levels and wellbeing. Interviews were transcribed and analysed using NVivo software.
Results:
Forty-five healthcare workers replied to the initial recruitment methods with fifteen not responding to follow-up communication. Overall, staff satisfaction with INFO debriefing was highly rated. A qualitative thematic analysis to saturation approach was used to analyse the data. Five main themes were identified: 1.Effect of debriefing on clinical practice and patient care. 2. Psychological safety and teamwork. 3. Emotional acknowledgment after critical events. 4. Managing work stress in the ED. 5. Barriers to debriefing.
Conclusions:
In this study, debriefing in the ED helped interprofessional healthcare workers manage stress, provide improved patient care and teamwork while acknowledging emotions. This study specifically involved INFO, however, there are similarities that make our findings applicable to other clinical event debriefing programs. We believe this study provides further evidence supporting debriefing in clinical care areas.
... 343,344 Several systems of care demonstrated that attention to the principles of quality improvement and implementation science could make a difference in patient outcomes. 128,130,[345][346][347][348] Specific barriers to implementation of resuscitation guidelines have been identified. Bigham et al 341 found 10 barriers that delayed implementation of the 2005 AHA guidelines by as many as 750 days in emergency medical services within the Resuscitation Outcomes Consortium. ...
... 372 It has been demonstrated that goal setting can improve system performance 373 and that measurement and feedback of individual performance can improve performance of various components of CPR for real cardiac arrest events and in training settings. 42,127,130,347,374,375 Furthermore, survival in the Resuscitation Outcomes Consortium increased during a 10-year period despite no randomized trial showing benefit for 1 therapy. It did, however, require careful data collection, comparisons across sites, enhanced training, and implementation of feedback to emergency medical services and providers. ...
... This step provides necessary feedback to team members and is crucial in enhancing team performance. Some studies have demonstrated that debriefing is associated with greater benefits for improving patient outcomes after cardiac arrest [50,51]. Traditional training settings may not reflect the environment of actual team-based resuscitation. ...
Background
Simulation is an increasingly used novel method for the education of medical professionals. This study aimed to systematically review the efficacy of high-fidelity (HF) simulation compared with low-fidelity (LF) simulation or no simulation in advanced life support (ALS) training.
Methods
A comprehensive search of the PubMed, Chinese Biomedicine Database, Embase, CENTRAL, ISI, and China Knowledge Resource Integrated Database was performed to identify randomized controlled trials (RCTs) that evaluated the use of HF simulation in ALS training. Quality assessment was based on the Cochrane Handbook for Systematic Reviews of Interventions version 5.0.1. The primary outcome was the improvement of knowledge and skill performance. The secondary outcomes included the participants’ confidence and satisfaction at the course conclusion, skill performance at one year, skill performance in actual resuscitation, and patient outcomes. Data were synthesized using the RevMan 5.4 software.
Results
Altogether, 25 RCTs with a total of 1,987 trainees were included in the meta-analysis. In the intervention group, 998 participants used HF manikins, whereas 989 participants received LF simulation-based or traditional training (classical training without simulation). Pooled data from the RCTs demonstrated a benefit in improvement of knowledge [standardized mean difference (SMD) = 0.38; 95% confidence interval (CI): 0.18–0.59, P = 0.0003 , I ² = 70%] and skill performance (SMD = 0.63; 95% CI: 0.21–1.04, P = 0.003, I ² = 92%) for HF simulation when compared with LF simulation and traditional training. The subgroup analysis revealed a greater benefit in knowledge with HF simulation compared with traditional training at the course conclusion (SMD = 0.51; 95% CI: 0.20–0.83, P = 0.003, I ² = 61%). Studies measuring knowledge at three months, skill performance at one year, teamwork behaviors, participants’ satisfaction and confidence demonstrated no significant benefit for HF simulation.
Conclusions
Learners using HF simulation more significantly benefited from the ALS training in terms of knowledge and skill performance at the course conclusion. However, further research is necessary to enhance long-term retention of knowledge and skill in actual resuscitation and patient’s outcomes.
... [13][14][15] Singlecentre data suggest that an educational bundle including point-ofcare bedside CPR training on manikins, and structured post-arrest debriefings are associated with improved neurologic outcome in children. 16 The multicentre Improving Outcomes from Paediatric Cardiac Arrest (ICU-RESUS) study assessed whether an educational bundle of structured debriefings that emphasized physiologic resuscitation targets, and point-of-care bedside education (simulated CPR with real-time feedback on a manikin) improved the rate of survival to hospital discharge with favourable neurologic outcome after p-IHCA. 17 Compared with usual care, the bundled intervention did not significantly improve survival to hospital discharge with favourable neurologic outcome in that study. ...
Aim:
To evaluate associations between characteristics of simulated point-of-care cardiopulmonary resuscitation (CPR) training with simulated and actual intensive care unit (ICU) CPR performance, and with outcomes of children after in-hospital cardiac arrest.
Methods:
This is a pre-specified secondary analysis of the ICU-RESUScitation Project; a prospective, multicentre cluster randomized interventional trial conducted in 18 ICUs from October 2016-March 2021. Point-of-care bedside simulations with real-time feedback to allow multidisciplinary ICU staff to practice CPR on a portable manikin were performed and quality metrics (rate, depth, release velocity, chest compression fraction) were recorded. Actual CPR performance was recorded for children 37 weeks post-conceptual age to 18 years who received chest compressions of any duration, and included intra-arrest haemodynamics and CPR mechanics. Outcomes included survival to hospital discharge with favourable neurologic status.
Results:
Overall, 18,912 point-of-care simulations were included. Simulation characteristics associated with both simulation and actual performance included site, participant discipline, and timing of simulation training. Simulation characteristics were not associated with survival with favourable neurologic outcome. However, participants in the top 3 sites for improvement in survival with favourable neurologic outcome were more likely to have participated in a simulation in the past month, on a weekday day, to be nurses, and to achieve targeted depth of compression and chest compression fraction goals during simulations than the bottom 3 sites.
Conclusions:
Point-of-care simulation characteristics were associated with both simulated and actual CPR performance. More recent simulation, increased nursing participation, and simulation training during daytime hours may improve CPR performance.
... 7,8 POHCA patients require rapid interventions early on including high-quality CPR, airway control, early epinephrine, and rapid defibrillation, as needed. 7,[9][10][11][12][13] Emphasis is also placed on post cardiac arrest care (PCAC), specifically, targeted temperature management (TTM), oxygen (O2) and carbon dioxide (CO2) targeting, hemodynamic monitoring, and prognostication, among other factors. 8 However, the in-hospital management of ongoing arrest in POHCA patients has not been investigated. ...
Introduction:
Pediatric out of hospital cardiac arrest (POHCA) is rare, with high mortality and neurological morbidity. Adherence to Pediatric Advanced Life Support guidelines standardizes in-hospital care and improves outcomes. We hypothesized that in-hospital care of POHCA patients was variable and deviations from guidelines were associated with higher mortality.
Methods:
POHCA patients in the London-Middlesex region between January 2012 and June 2020 were included. The care of children with ongoing arrest (intra-arrest) and post-arrest outcomes were reviewed using the Children's Hospital, London Health Sciences Centre (LHSC) patient database and the Adverse Event Management System.
Results:
50 POHCA patients arrived to hospital, with 15 (30%) patients admitted and 2 (4.0%) surviving to discharge, both with poor neurological outcomes and no improvement at 90 days. Deviations occurred at every event with intra-arrest care deviations occurring mostly in medication delivery and defibrillation (98%). Post-arrest deviations occurred mostly in temperature monitoring (60%). Data missingness was 15.9% in the intra-arrest and 1.7% in the post-arrest group.
Discussion:
Deviations commonly occurred in both in-hospital arrest and post-arrest care. The study was under-powered to identify associations between DEVs and outcomes. Future work includes addressing specific deviations in intra-arrest and post-arrest care of POHCA patients and standardizing electronic documentation.
... However, if disruptive events are here to stay (case in point, the pandemic) and if the current conditions of the system are not ideal for fully embracing plasticity, then maybe this is the time to start pondering about creative ways in which we can strategically infuse plasticity in our healthcare teams to leverage their capacity for resilient teaming. For instance, many have demonstrated the benefits of debriefing in team training, including improved clinical outcomes, team performance and identification of errors [34][35][36]. While debriefing could be a powerful strategy for infusing plasticity, evidence shows that it is still an underused team training strategy [37]. ...
The resilience of a healthcare system hinges on the adaptability of its teams. Thus far, healthcare teams have relied on well-defined scopes of practice to fulfill their safety mandate. While this feature has proven effective when dealing with stable situations, when it comes to disruptive events, healthcare teams find themselves navigating a fine balance between safety and resilience. Therefore, a better understanding of how the safety vs resilience trade-off varies under different circumstances is necessary if we are to promote and better train for resilience in modern healthcare teams. In this paper, we aim to bring awareness to the sociobiology analogy that healthcare teams might find useful during moments when safety and adaptability have the potential to conflict. Three principles underpin the sociobiology analogy: communication, decentralization, and plasticity. Of particular interest in this paper is plasticity whereby swapping roles or tasks becomes an adaptive, rather than a maladaptive, response teams could embrace when facing disruptive situations. While plasticity has naturally evolved in social insects, infusing plasticity in healthcare teams requires intentional training. Inspired by the sociobiology analogy, such training must value the ability: a) to read each other's cues and miscues, b) to step aside when others had the necessary skills, even if outside their scope, c) to deviate from protocols, and d) to foster cross-training. If the goal is to increase a team's behavioural flexibility and boost their resilience, this training mindset should become second nature.
... [23] In this context, Cutrer and colleagues described informed self-assessment as important with feedback that is 'clear, timely, specific and constructive feedback offered by trusted, credible supervisors' . These ideas would appear relevant to debriefer development with the DART tool, as well as other assessment tools aiding this process • No correlation/association was observed between DART scores and DASH scores • In other settings, simple objective data has been clearly shown to improve actual performance as follows: 1) Real-time objective audio-visual feedback of CPR performance such as chest compression depth, chest compression rate, and ventilation rate lead to improvements of those objective measures of CPR performance and improvements in the rate of ROSC [2,23] 2) Real-time quantitative feedback in the form of mean concentric velocity displayed in front of participants leads to improvements in physical performance of strength exercises and improvements in motivation, competitiveness, and mood [24] Cutrer et al. suggested that using data can be a powerful tool to change behaviour [25] Implication What is the impact of the DART tool on debriefers? ...
Background:
Debriefing is crucial for enhancing learning following healthcare simulation. Various validated tools have been shown to have contextual value for assessing debriefers. The Debriefing Assessment in Real Time (DART) tool may offer an alternative or additional assessment of conversational dynamics during debriefings.
Methods:
This is a multi-method international study investigating reliability and validity. Enrolled raters (n = 12) were active simulation educators. Following tool training, the raters were asked to score a mixed sample of debriefings. Descriptive statistics are recorded, with coefficient of variation (CV%) and Cronbach's α used to estimate reliability. Raters returned a detailed reflective survey following their contribution. Kane's framework was used to construct validity arguments.
Results:
The 8 debriefings (μ = 15.4 min (SD 2.7)) included 45 interdisciplinary learners at various levels of training. Reliability (mean CV%) for key components was as follows: instructor questions μ = 14.7%, instructor statements μ = 34.1%, and trainee responses μ = 29.0%. Cronbach α ranged from 0.852 to 0.978 across the debriefings. Post-experience responses suggested that DARTs can highlight suboptimal practices including unqualified lecturing by debriefers.
Conclusion:
The DART demonstrated acceptable reliability and may have a limited role in assessment of healthcare simulation debriefing. Inherent complexity and emergent properties of debriefing practice should be accounted for when using this tool.
... Although there are challenges associated with formative group feedback, participants noted the benefit of highlighting what a resident did well in group settings. Group debriefs are commonly utilized in simulation and can improve clinical outcomes [15]. Further research is warranted to explore whether incorporating positive feedback in a group setting decreases vulnerability and increases psychological safety. ...
Purpose:
Residents and attendings agree on the importance of feedback to resident education. However, while faculty report providing frequent feedback, residents often do not perceive receiving it, particularly in the context of teaching. Given the nuanced differences between feedback and teaching, we aimed to explore resident and attending perceptions of feedback and teaching in the clinical setting.
Methods:
We conducted a qualitative study of internal medicine residents and attendings from December 2018 through March 2019 at a large US academic medical center (Massachusetts General Hospital) to investigate perceptions of feedback in the inpatient clinical setting. Residents and faculty were recruited to participate in focus groups. Data were analyzed using thematic analysis to explore perspectives and barriers to feedback provision and identification.
Results:
Five focus groups included 33 total participants in 3 attending (n=20) and 2 resident (n=13) groups. Thematic analysis of focus group transcripts identified 7 themes which organized into three thematic categories: (1) disentangling feedback and teaching, (2) delivering high-quality feedback, and (3) experiencing feedback in the group setting. Residents and attendings highlighted important themes in discriminating feedback from teaching. They indicated that while feedback is reactive in response to an action or behavior, teaching is proactive and oriented toward future endeavors.
Conclusion:
Confusion between the critical concepts of teaching and feedback may be minimized by allowing them to each have their intended impact, either in response to prior events or aimed toward those yet to take place.
... Interdisciplinary team debriefing with the basic assumption that all participants have the best interest of the patient in mind, can play a role in improving CPR quality. 87,391 To properly evaluate the effectiveness of their CPR attempts, it is important that emergency clinicians are informed about the outcome of their patients in a systematic quality improvement system. 29 Quality measurement, surveillance programs and feedback provided to prehospital providers regarding patient's outcome, and the team's performance compared with published guidelines, improves care due to the so called Hawthorne effect. ...
... While debriefing is frequently integrated into simulation-based training, it can be a powerful tool to reflect on clinical care and is often underutilized [83][84][85][86]. Both NRP and HBB have recently evolved to include debriefing as an essential component of their simulation trainings [4,87,88]. ...
One third of all neonatal deaths are caused by intrapartum-related events, resulting in neonatal respiratory depression (i.e., failure to breathe at birth). Evidence-based resuscitation with stimulation, airway clearance, and positive pressure ventilation reduces mortality from respiratory depression. Improving adherence to evidence-based resuscitation is vital to preventing neonatal deaths caused by respiratory depression. Standard resuscitation training programs, combined with frequent simulation practice, have not reached their life-saving potential due to ongoing gaps in bedside performance. Complex neonatal resuscitations, such as those involving positive pressure ventilation, are relatively uncommon for any given resuscitation provider, making consistent clinical practice an unrealistic solution for improving performance. This review discusses strategies to allow every birth to act as a learning event within the context of both high- and low-resource settings. We review strategies that involve clinical-decision support during newborn resuscitation, including the visual display of a resuscitation algorithm, peer-to-peer support, expert coaching, and automated guidance. We also review strategies that involve post-event reflection after newborn resuscitation, including delivery room checklists, audits, and debriefing. Strategies that make every birth a learning event have the potential to close performance gaps in newborn resuscitation that remain after training and frequent simulation practice, and they should be prioritized for further development and evaluation.
... [11][12][13][14][15] Performance debriefings after IHCA are associated with improved CPR quality and survival outcomes. 16,17 International resuscitation guidelines therefore recommend the use of data-driven performance evaluation debriefings to improve survival outcomes. [18][19][20] The guidelines also emphasize that healthcare systems with a responsibility for the management of patients in cardiac arrest should evaluate their cardiac arrest treatment to ensure the best achievable survival rates. ...
Purpose:
To improve cardiac arrest survival, international resuscitation guidelines emphasize measuring the quality of cardiopulmonary resuscitation (CPR). We aimed to investigate CPR quality during in-hospital cardiac arrest (IHCA) and study long-term survival outcomes.
Patients and methods:
This was a cohort study of IHCA from December 2011 until November 2014. Data were collected from the hospital switch board, patient records, and from defibrillators. Impedance data from defibrillators were analyzed manually at the level of single compressions. Long-term survival at 1-, 3-, and 5 years is reported.
Results:
The study included 189 IHCAs; median (interquartile range (IQR)) time to first rhythm analysis was 116 (70-201) seconds and median (IQR) time to first defibrillation was 133 (82-264) seconds. Median (IQR) chest compression rate was 126 (119-131) per minute and chest compression fraction (CCF) was 78% (69-86). Thirty-day survival was 25%, while 1-year-, 3-year-, and 5-year survival were 21%, 14%, and 13%, respectively. There was no significant association between any survival outcomes and CCF, whereas chest compression rate was associated with survival to 30 days and 3 years. Overall, 5-year survival was associated with younger age (median 68 vs 74 years, p=0.003), less comorbidity (Charlson comorbidity index median 3 vs 5, p<0.001), and witnessed cardiac arrest (96% vs 77%, p=0.03).
Conclusion:
We established a systematic collection of IHCA CPR quality data to measure and improve CPR quality and long-term survival outcomes. Median time to first rhythm check/defibrillation was <3 minutes, but median chest compression rate was too fast and median CCF slightly below 80%. More than half of 30-day survivors were still alive at 5 years.
... Debriefings have a positive impact on team performance and employee satisfaction, leading to an increase of the quality of care. Furthermore, they increase survival rates of resuscitated children (35,36). ...
... Its incorporation into clinical practice allows the whole team to discuss real events, encourages reflection and allows a deep level of experiential learning. There is growing evidence that it contributes to improving clinical outcomes [4][5][6]. It contributes to building resilience, strengthening shared mental models and facilitating adaptation to changing circumstances, such as the ones faced in this crisis [7][8][9]. ...
The COVID-19 pandemic and the subsequent pressures on healthcare staff and resources have exacerbated the need for clinical teams to reflect and learn from workplace experiences. Surges in critically ill patients, the impact of the disease on the workforce and long term adjustments in work and life have upturned our normality. Whilst this situation has generated a new ‘connectedness’ within healthcare workers, it also continues to test our resilience.
An international multi-professional collaboration has guided the identification of ongoing difficulties to effective communication and debriefing, as well as emerging opportunities to promote a culture of dialogue. This article outlines pandemic related barriers and new possibilities categorising them according to task management, teamwork, situational awareness and decision making. It describes their direct and indirect impact on clinical debriefing and signposts towards solutions to overcome challenges and, building on new bridges, advance team conversations that allow us to learn, improve and support each other.
This pandemic has brought clinical professionals together; nevertheless, it is essential to invest in further developing and supporting cohesive teams. Debriefing enables healthcare teams and educators to mitigate stress, build resilience and promote a culture of continuous learning and patient care improvement.
... The pediRES-Q Collaborative offers a bundle of QI interventions geared toward improving CPR outcomes for children that hospitals may choose to fully or partially implement. The bundle elements include as follows: (1) a checklist (see Supplemental Digital Content 1, http:// links.lww.com/PQ9/A294) for the identification of patients at risk for cardiac arrest 16,17 ; (2) rolling refreshers to provide bedside just-in-time CPR training 18 ; (3) structured "hot" debriefings immediately following cardiac arrest events 19 ; (4) "cold" data-informed cardiac arrest debriefings provided at a later time 20,21 ; and (5) ...
Introduction:
Pediatric quality improvement (QI) collaboratives are multisite clinical networks that support cooperative learning. Our goal is to identify the contextual facilitators and barriers to implementing QI resuscitation interventions within a multicenter resuscitation collaborative.
Methods:
A mixed-methods evaluation of the contextual facilitators and barriers to implementation of a resuscitation QI bundle. We administered a quantitative questionnaire, the Model for Understanding Success in Quality (MUSIQ), to the Pediatric Resuscitation Quality (pediRES-Q) Collaborative. Its primary goal is to optimize the care of children who experience in-hospital cardiac arrest through a resuscitation QI bundle. We also conducted semistructured phone interviews with site primary investigators adapted from the Consolidated Framework for Implementation Research qualitative interview guide.
Results:
All 13 actively participating US sites completed the MUSIQ questionnaire. Total MUSIQ scores ranged from 86.0 to 140.5 (median of 118.7, interquartile range 103.6-124.5). Evaluation of the QI team subsection noted a mean score of 5.5 for low implementers and 6.1 for high implementers (P = 0.02). We conducted 8 interviews with the local QI team leadership. Contextual facilitators included a unified institutional approach to QI, a fail forward climate, leadership support, strong microculture, knowledge of other organizations, and prioritization of goals. Contextual barriers included low team tenure, no specific allocation of resources, lack of formalized QI training, and lack of support and buy-in by leaders and staff.
Conclusions:
Using mixed methods, we identified an association between the local QI team's strength and the successful implementation of the QI interventions.
... After clinical cardiopulmonary resuscitation events, debriefing programmes have demonstrated improved rate of return of spontaneous circulation, neurologic outcomes, hands-off compression times, and time delay to first compression. 11 Gilmartin et al. 2 found that after introducing a new programme to hot debrief after every cardiac arrest in their ED, the vast majority of their participants felt they benefited both clinically and psychologically from the process. ...
Objectives
To assess associations between outcome and cardiopulmonary resuscitation (CPR) quality for in-hospital cardiac arrest (IHCA) in children with medical cardiac, surgical cardiac, or noncardiac disease.
Design
Secondary analysis of a multicenter cluster randomized trial, the ICU-RESUScitation Project (NCT02837497, 2016–2021).
Setting
Eighteen PICUs.
Patients
Children less than or equal to 18 years old and greater than or equal to 37 weeks postconceptual age receiving chest compressions (CC) of any duration during the study.
Interventions
None
Measurements and Main Results
Of 1,100 children with IHCA, there were 273 medical cardiac (25%), 383 surgical cardiac (35%), and 444 noncardiac (40%) cases. Favorable neurologic outcome was defined as no more than moderate disability or no worsening from baseline Pediatric Cerebral Performance Category at discharge. The medical cardiac group had lower odds of survival with favorable neurologic outcomes compared with the noncardiac group (48% vs 55%; adjusted odds ratio [aOR] [95% CI], aOR 0.59 [95% CI, 0.39–0.87], p = 0.008) and surgical cardiac group (48% vs 58%; aOR 0.64 [95% CI, 0.45–0.9], p = 0.01). We failed to identify a difference in favorable outcomes between surgical cardiac and noncardiac groups. We also failed to identify differences in CC rate, CC fraction, ventilation rate, intra-arrest average target diastolic or systolic blood pressure between medical cardiac versus noncardiac, and surgical cardiac versus noncardiac groups. The surgical cardiac group had lower odds of achieving target CC depth compared to the noncardiac group (OR 0.15 [95% CI, 0.02–0.52], p = 0.001). We failed to identify a difference in the percentage of patients achieving target CC depth when comparing medical cardiac versus noncardiac groups.
Conclusions
In pediatric IHCA, medical cardiac patients had lower odds of survival with favorable neurologic outcomes compared with noncardiac and surgical cardiac patients. We failed to find differences in CPR quality between medical cardiac and noncardiac patients, but there were lower odds of achieving target CC depth in surgical cardiac compared to noncardiac patients.
Aim:
Develop a novel, physiology-based measurement of duty cycle (Arterial BloodPressure - Area Duty Cycle [ABP-ADC]) and evaluate the association of ABP-ADCwith intra-arrest hemodynamics and patient outcomes.
Methods:
This was a secondary retrospective study of prospectively collected datafrom the ICU-RESUS trial (NCT02837497). Invasive arterial waveform data were usedto derive ABP-ADC. The primary exposure was ABP-ADC group (<30%; 30-35%;>35%). The primary outcome was systolic blood pressure (sBP). Secondary outcomesincluded intra-arrest physiologic goals, CPR quality targets, and patient outcomes. Inan exploratory analysis, adjusted splines and receiver operating characteristic (ROC)curves were used to determine an optimal ABP-ADC associated with improvedhemodynamics and outcomes using a multivariable model.
Results:
Of 1129 CPR events, 273 had evaluable arterial waveform data. Mean agewas 2.9 + 4.9 years. Mean ABP-ADC was 32.5% + 5.0%. In univariable analysis,higher ABP-ADC was associated with lower sBP (p<0.01) and failing to achieve sBPtargets (p<0.01). Other intra-arrest physiologic parameters, quality metrics, and patientoutcomes were similar across ABP-ADC groups. Using spline / ROC analysis andclinical judgement, the optimal ABP-ADC cut point was set at 33%. On multivariableanalysis, sBP was significantly higher (point estimate 13.18 mmHg, CI95 5.30 - 21.07,p<0.01) among patients with ABP-ADC <33%. Other intra-arrest physiologic andpatient outcomes were similar.
Conclusions:
In this multicenter cohort, a lower ABP-ADC was associated with highersBPs during CPR. Although ABP-ADC was not associated with outcomes, furtherstudies are needed to define the interactions between CPR mechanics and intra-arrestpatient physiology.
This chapter explores the means by which practicing intensivists address poor outcomes after they have occurred. That is, advice around managing the aftermath of adverse events, mistakes, and deaths. Key to this process is the need to balance the clinical need for a close examination of the events with the potential emotional distress such processes can induce among those that were present. The risk management process is discussed as well as the importance of an open, honest approach when speaking with affected family members. The chapter concludes with a review of debriefing approaches and the value of professional mental health support for those involved in such events.KeywordsRiskHarmErrorResilienceCopingDebriefingRoot cause analysis
Objective:
Hot debriefings are communications among team members occurring shortly after an event. They have been shown to improve team performance and communication. Best practice guidelines encourage hot debriefings, but these are often not routinely performed. We aim to describe the development and implementation of a multidisciplinary hot debriefing process in our pediatric emergency department (ED), and its impact on hot debriefing completion and provider perceptions.
Methods:
An internal tool and protocol for hot debriefings were developed by integrating responses from a survey of those who work in the ED at our institution and previously published debriefing tools. Charge nurses and pediatric emergency medicine physicians were trained to lead hot debriefings. Surveys on the perception of hot debriefings were administered before and 6 months postimplementation.Twelve-month baseline data were established by asking physicians who cared for patients who died in the ED or within 48 hours of admission to recall debrief completion. Debriefs were then prospectively tracked for 6 months postimplementation.
Results:
Debrief completion for patient deaths in the ED or within 48 hours of admission increased from 23% (5/22) to 75% (12/16) (P < 0.001). When assessing just those deaths within the ED, this number increased from 31% (5/16) to 85% (11/13) (P < 0.001).There were 98 responses to a baseline survey (response rate, 60.5%). Most who were surveyed felt that debriefs rarely occurred, preferred hot debriefings to cold debriefings, and felt that more hot debriefings should occur. Perceived barriers included lack of time, interest, protocol, trained facilitators, departmental support, and inability to gather the team.There were 88 responses to a postintervention survey (response rate, 56.8%), 50 of which had participated in a debrief and were included in analysis. Those surveyed felt that debriefs occurred more often and were more often valuable. Most perceived that barriers were significantly reduced. Most respondents felt that hot debriefs helped address systems issues and improved performance.
Conclusions:
Implementation of a protocol for physician or charge nurse-led hot debriefings in our pediatric ED resulted in increased completion, perceived barrier reduction, and a uniform approach to address identified issues. Pediatric EDs should consider adoption of a hot debriefing protocol given these benefits.
In-hospital cardiac arrests that occur outside of the intensive care unit may require transportation during active cardiopulmonary resuscitation. Studies have shown that high-quality cardiopulmonary resuscitation is imperative for survival with preserved neurologic function. We sought to determine if high-quality cardiopulmonary resuscitation is maintained during simulated transportation of paediatric in-hospital cardiac arrest.
Randomized crossover simulated study of paediatric in-hospital cardiac arrest with 10 teams composed of five providers (physicians, advanced practice providers, nurses and respiratory therapists). Teams remained in a simulation room or transported the mannequin between two rooms. The primary analysis compared chest compression fraction in stationary versus transport simulations. Secondary analyses included additional cardiopulmonary resuscitation quality metrics with comparison to the 2015 American Heart Association standards.
There was no significant difference in chest compression fraction or rate between the transport and stationary groups. 92%, 72% and 26% of epochs met American Heart Association criteria for compression fraction, rate and depth, respectively. Stationary simulations were more likely to meet recommendations for combined quality metrics, including compression fraction and rate (77 vs. 53;
Chest compression fraction was preserved during simulated in-hospital cardiac arrest with transport. However, the transport simulation was less likely to meet American Heart Association recommendations for combined metrics. Similar to previous cardiopulmonary resuscitation quality studies, both teams failed to meet depth requirements in the majority of simulations.
Background
Simulation is an increasingly used novel method for the education of medical professionals.This study aimed to systematically review the efficacy of high-fidelity (HF) simulation compared with low-fidelity (LF) simulation or no simulation in advanced life support (ALS) training.
Methods
A comprehensive search of the PubMed, Chinese Biomedicine Database, Embase, CENTRAL, ISI, and China Knowledge Resource Integrated Database was performed to identify randomized controlled trials (RCTs) that evaluated the use of HF simulation in ACLS training. Quality assessment was based on the Cochrane Handbook for Systematic Reviews of Interventions version 5.0.1. The primary outcome was the improvement of knowledge and skill performance. The secondary outcomes included the participants’ confidence and satisfaction at the course conclusion, skill performance at one year, skill performance in actual resuscitation, and patient outcomes. Data were synthesized using the RevMan 5.4 software.
Results
Altogether, 25 RCTs with a total of 1987 trainees were included in the meta-analysis. In the intervention group, 998 participants used HF manikins, whereas 989 participants received LF simulation-based or traditional training (classical training without simulation). Pooled data from the RCTs demonstrated a benefit in improvement of knowledge [standardized mean difference (SMD) = 0.38; 95% confidence interval (CI): 0.18–0.59, P = 0.0003, I² = 71%] and skill performance (SMD = 0.63; 95% CI: 0.21–1.04, P = 0.003, I² = 93%) for HF simulation when compared with LF simulation and traditional training. The subgroup analysis revealed a greater benefit in knowledge with HF simulation compared with traditional training at the course conclusion (SMD = 0.50; 95% CI: 0.17–0.83, P = 0.003, I² = 67%). Studies measuring knowledge at three months, skill performance at one year, teamwork behaviors, participants’ satisfaction and confidence demonstrated no significant benefit for HF simulation.
Conclusions
Learners using HF simulation more significantly benefited from the ALS training in terms of knowledge and skill performance at the course conclusion. However, further research is necessary to enhance long-term retention of knowledge and skill in actual resuscitation and patient’s outcomes.
Resuscitations are complex events that require teamwork to succeed. In addition to the technical skills involved, a host of nontechnical skills are critical for optimal medical care delivery. These skills include mental preparation; planning for tasks and roles; leadership to guide resuscitation progress; and clear, closed-loop communication. Concerns and error detection should be escalated in an established format. Debriefing after the event helps identify learning points to carry forward for the next resuscitation. Support of the team providing this intense form of care is crucial to protect the mental health and function of providers.
Background and objectives
Clinical debriefing (CD) following a clinical event has been found to confer benefits for staff and has potential to improve patient outcomes. Use of a structured tool to facilitate CD may provide a more standardised approach and help overcome barriers to CD; however, we presently know little about the tools available. This systematic review aimed to identify tools for CD in order to explore their attributes and evidence for use.
Methods
A systematic review was conducted in line with PRISMA standards. Five databases were searched. Data were extracted using an electronic form and analysed using critical qualitative synthesis. This was guided by two frameworks: the ‘5 Es’ (defining attributes of CD: educated/experienced facilitator, environment, education, evaluation and emotions) and the modified Kirkpatrick’s levels. Tool utility was determined by a scoring system based on these frameworks.
Results
Twenty-one studies were included in the systematic review. All the tools were designed for use in an acute care setting. Criteria for debriefing were related to major or adverse clinical events or on staff request. Most tools contained guidance on facilitator role, physical environment and made suggestions relating to psychological safety. All tools addressed points for education and evaluation, although few described a process for implementing change. Staff emotions were variably addressed. Many tools reported evidence for use; however, this was generally low-level, with only one tool demonstrating improved patient outcomes.
Conclusion
Recommendations for practice based on the findings are made. Future research should aim to further examine outcomes evidence of these tools in order to optimise the potential of CD tools for individuals, teams, healthcare systems and patients.
Background:
Debriefing in the pediatric emergency department (PED) is an invaluable tool to improve team well-being, communication, and performance. Despite evidence, surveys have reported heavy workload as a barrier to debriefing leading to missed opportunities for improvement in an already busy ED. The study aims to determine the association between the incidence of debriefing after pediatric trauma resuscitations and PED crowding.
Methods:
A total of 491 Trauma One activations in Riley Children's Hospital Pediatric Emergency Department that presented between April 2018 to December 2019 were included in the study. Debriefing documentations, patient demographics, time and date of presentation, mechanism of injury, injury severity score, disposition from PED, and length of stay (LOS) were collected and analyzed. The National Emergency Department Overcrowding Scale score at arrival, Average LOS, total PED census, total PED waiting room census, and rates of left without being seen were compared between groups.
Results:
Of 491 Trauma One activations presented to our PED, 50 (10%) trauma evaluations had documented debriefing. The National Emergency Department Overcrowding Scale score at presentation was significantly lower in those with debriefing versus without debriefing. In addition, the PED hourly census, waiting room census, average LOS, and left without being seen were also significantly lower in the group with debriefing. In addition, trauma cases with debriefing had a higher proportion of patients with profound injuries and discharges to the morgue.
Conclusions:
Pediatric emergency department crowding is a significant barrier to debriefing after trauma resuscitations. However, profound injuries and traumatic pediatric deaths remain the strongest predictors in conducting debriefing regardless of PED crowding status.
Dit hoofdstuk gaat in op het samenwerkingsconcept crew resource management (CRM). Goede communicatie, leiderschap en situational awareness zijn voor een team essentieel bij de vaak multidiscipliniaire en interprofessionele opvang en behandeling van een acute patiënt. Deze vaardigheden worden ook wel non-technical skills genoemd.
Objectives:
Arterial diastolic blood pressure (DBP) greater than 25 mm Hg in infants and greater than 30 mm Hg in children greater than 1 year old during cardiopulmonary resuscitation (CPR) was associated with survival to hospital discharge in one prospective study. We sought to validate these potential hemodynamic targets in a larger multicenter cohort.
Design:
Prospective observational study.
Setting:
Eighteen PICUs in the ICU-RESUScitation prospective trial from October 2016 to March 2020.
Patients:
Children less than or equal to 18 years old with CPR greater than 30 seconds and invasive blood pressure (BP) monitoring during CPR.
Interventions:
None.
Measurements and main results:
Invasive BP waveform data and Utstein-style CPR data were collected, including prearrest patient characteristics, intra-arrest interventions, and outcomes. Primary outcome was survival to hospital discharge, and secondary outcomes were return of spontaneous circulation (ROSC) and survival to hospital discharge with favorable neurologic outcome. Multivariable Poisson regression models with robust error estimates evaluated the association of DBP greater than 25 mm Hg in infants and greater than 30 mm Hg in older children with these outcomes. Among 1,129 children with inhospital cardiac arrests, 413 had evaluable DBP data. Overall, 85.5% of the patients attained thresholds of mean DBP greater than or equal to 25 mm Hg in infants and greater than or equal to 30 mm Hg in older children. Initial return of circulation occurred in 91.5% and 25% by placement on extracorporeal membrane oxygenator. Survival to hospital discharge occurred in 58.6%, and survival with favorable neurologic outcome in 55.4% (i.e. 94.6% of survivors had favorable neurologic outcomes). Mean DBP greater than 25 mm Hg for infants and greater than 30 mm Hg for older children was significantly associated with survival to discharge (adjusted relative risk [aRR], 1.32; 1.01-1.74; p = 0.03) and ROSC (aRR, 1.49; 1.12-1.97; p = 0.002) but did not reach significance for survival to hospital discharge with favorable neurologic outcome (aRR, 1.30; 0.98-1.72; p = 0.051).
Conclusions:
These validation data demonstrate that achieving mean DBP during CPR greater than 25 mm Hg for infants and greater than 30 mm Hg for older children is associated with higher rates of survival to hospital discharge, providing potential targets for DBP during CPR.
Health care teams are groups of highly skilled experts who may often form inexpert teams because of a lack of collective competence. Because teamwork and collaboration form the foundation of effective clinical practice, factors that promote collective competence demand exploration. The authors review team reflexivity (TR), a concept from the psychology and management literatures, and how it could contribute to the collective competence of health care teams. TR captures a team’s ability to reflect collectively on group objectives, strategies, goals, processes, and outcomes of past, current, and future performance to process key information and adapt accordingly. As an overarching process that promotes team functioning, TR builds shared mental models as well as triggering team adaptation and learning. The authors present a conceptual framework for TR in health care, describing three phases in which TR may occur: pre-action TR (briefing before patient care), in-action TR (deliberations during active patient care), and post-action TR (debriefing after patient care). Depending on the phase, TR targets either goals, taskwork, teamwork, or resources and leads to different outcomes (e.g., optimal preparation, a shared mental model, adaptation, or learning). This novel conceptual framework incorporates various constructs related to reflection and unites them under the umbrella of TR. Viewing reflection through a team lens may guide future research about team functioning, optimize training efforts, and elucidate mechanisms for workplace learning, with better patient care as the ultimate goal.
Objectives:
The facilitated discussion of events through clinical event debriefing (CED) can promote learning and wellbeing, but resident involvement is often limited. Although the graduate medical education field supports CED, interventions to promote resident involvement are limited by poor insight into how residents experience CED. The objective of this study was to characterize pediatric resident experiences with CED, with a specific focus on practice barriers and facilitators.
Methods:
We conducted this qualitative study between November and December 2020 at a large, free-standing children's hospital. We recruited pediatric residents from postgraduate years 1 to 4 to participate in virtual focus groups. Focus groups were digitally recorded, deidentified, and transcribed. Transcripts were entered into coding software for analysis. We analyzed the data using a modified grounded theory approach to identify major themes.
Results:
We conducted 4 mixed-level focus groups with 26 residents. Our analysis identified multiple barriers and facilitators of resident involvement in CED. Several barriers were logistical in nature, but the most salient barriers were derived from unique features of the resident role. For example, residents described the transience of their role as a barrier to both participating and engaging in CED. However, they described advancing professional experience and the desire for reflective learning as facilitators.
Conclusions:
Residents in this study highlighted many factors affecting their participation and engagement in CED, including barriers related to the unique features of their role. On the basis of resident experiences, we propose several recommendations for CED practice that graduate medical education programs and hospitals should consider for supporting resident involvement in CED.
Background:
Clinical debriefing (CD) improves patient safety and builds team resilience.
Purpose:
We describe the current use of CD by multiprofessional Spanish cardiology team members.
Methods:
A self-administered survey exploring 31 items was disseminated online in October 2020. A comparison was made between respondents that who experience in CD with inexperienced respondents. Inferential analysis was done using Pearson's χ2 test.
Results:
Out of 167 valid responses, 45.5% had been completed by cardiology nurses. One-third of the respondents had experience in CD. Most common situations preceding CD were those with negative outcomes (81.8%). Time constraint was the most commonly reported barrier (76.3%); however, it was significantly less than the expectation of inexperienced respondents (92%, P < .01). Overall, only 28.2% reported self-confidence in their skills to lead a CD.
Conclusions:
There is a necessity in Spanish cardiology teams to receive training in CD and embed it in their daily practice.
Physical and mental disabilities resulting from a child’s cardiac arrest are of exceptional family and social concern. Recent studies showed that the quality of pediatric resuscitation often does not meet recommended standards. Implementation of these 10 evidence-based measures published here can help improve survival rates and morbidity in resuscitated children.These 10 theses are intended to focus on the broad range of issues surrounding resuscitation of children and adolescents. It begins with improved prevention and recognition of life-threatening events in children to prevent respiratory and circulatory arrest. In the case of resuscitation, it can only be effective if consistent and sustained training is provided. Learning from each patient is the most important thing. The quality of resuscitation and the postresuscitation phase must be measured and evaluated to identify aspects for optimization. Structured collection of treatment and outcome data in a centralized, mandatory registry offers the opportunity to identify strengths of in-hospital and out-of-hospital care and to develop concepts for quality improvement. These theses and basic principles are also supported by the Austrian, German, and Swiss Resuscitation Councils and have already been published in Frontiers in Pediatrics.
Abstract Background Medical emergencies are complex and stressful, especially for the young and inexperienced. Cognitive aids (CA) have been shown to facilitate management of simulated medical emergencies by experienced teams. In this randomized trial we evaluated guideline adherence and treatment efficacy in simulated medical emergencies managed by residents with and without CA. Methods Physicians attending educational courses executed simulated medical emergencies. Teams were randomly assigned to manage emergencies with or without CA. Primary outcome was risk reduction of essential working steps. Secondary outcomes included prior experience in emergency medicine and CA, perceptions of usefulness, clinical relevance, acceptability, and accuracy in CA selection. Participants were grouped as “medical” (internal medicine and neurology) and “perioperative” (anesthesia and surgery) regarding their specialty. The study was designed as a prospective randomized single-blind study that was approved by the ethical committee of the University Duisburg-Essen (19-8966-BO). Trial registration: DRKS, DRKS00024781. Registered 16 March 2021—Retrospectively registered, http://www.drks.de/DRKS00024781 . Results Eighty teams participated in 240 simulated medical emergencies. Cognitive aid usage led to 9% absolute and 15% relative risk reduction. Per protocol analysis showed 17% absolute and 28% relative risk reduction. Wrong CA were used in 4%. Cognitive aids were judged as helpful by 94% of the participants. Teams performed significantly better when emergency CA were available (p
Bystander cardiopulmonary resuscitation (CPR) is critical to increasing survival from out-of-hospital cardiac arrest. However, the percentage of cases in which an individual receives bystander CPR is actually low, at only 35% to 40% globally. Preparing lay responders to recognize the signs of sudden cardiac arrest, call 9-1-1, and perform CPR in public and private locations is crucial to increasing survival from this public health problem. The objective of this scientific statement is to summarize the most recent published evidence about the lay responder experience of training, responding, and dealing with the residual impact of witnessing an out-of-hospital cardiac arrest. The scientific statement focuses on the experience-based literature of actual responders, which includes barriers to responding, experiences of doing CPR, use of an automated external defibrillator, the impact of dispatcher-assisted CPR, and the potential for postevent psychological sequelae. The large body of qualitative and observational studies identifies several gaps in crucial knowledge that, if targeted, could increase the likelihood that those who are trained in CPR will act. We suggest using the experience of actual responders to inform more contextualized training, including the implications of performing CPR on a family member, dispelling myths about harm, training and litigation, and recognition of the potential for psychologic sequelae after the event.
Importance:
Approximately 40% of children who experience an in-hospital cardiac arrest survive to hospital discharge. Achieving threshold intra-arrest diastolic blood pressure (BP) targets during cardiopulmonary resuscitation (CPR) and systolic BP targets after the return of circulation may be associated with improved outcomes.
Objective:
To evaluate the effectiveness of a bundled intervention comprising physiologically focused CPR training at the point of care and structured clinical event debriefings.
Design, setting, and participants:
A parallel, hybrid stepped-wedge, cluster randomized trial (Improving Outcomes from Pediatric Cardiac Arrest-the ICU-Resuscitation Project [ICU-RESUS]) involving 18 pediatric intensive care units (ICUs) from 10 clinical sites in the US. In this hybrid trial, 2 clinical sites were randomized to remain in the intervention group and 2 in the control group for the duration of the study, and 6 were randomized to transition from the control condition to the intervention in a stepped-wedge fashion. The index (first) CPR events of 1129 pediatric ICU patients were included between October 1, 2016, and March 31, 2021, and were followed up to hospital discharge (final follow-up was April 30, 2021).
Intervention:
During the intervention period (n = 526 patients), a 2-part ICU resuscitation quality improvement bundle was implemented, consisting of CPR training at the point of care on a manikin (48 trainings/unit per month) and structured physiologically focused debriefings of cardiac arrest events (1 debriefing/unit per month). The control period (n = 548 patients) consisted of usual pediatric ICU management of cardiac arrest.
Main outcomes and measures:
The primary outcome was survival to hospital discharge with a favorable neurologic outcome defined as a Pediatric Cerebral Performance Category score of 1 to 3 or no change from baseline (score range, 1 [normal] to 6 [brain death or death]). The secondary outcome was survival to hospital discharge.
Results:
Among 1389 cardiac arrests experienced by 1276 patients, 1129 index CPR events (median patient age, 0.6 [IQR, 0.2-3.8] years; 499 girls [44%]) were included and 1074 were analyzed in the primary analysis. There was no significant difference in the primary outcome of survival to hospital discharge with favorable neurologic outcomes in the intervention group (53.8%) vs control (52.4%); risk difference (RD), 3.2% (95% CI, -4.6% to 11.4%); adjusted OR, 1.08 (95% CI, 0.76 to 1.53). There was also no significant difference in survival to hospital discharge in the intervention group (58.0%) vs control group (56.8%); RD, 1.6% (95% CI, -6.2% to 9.7%); adjusted OR, 1.03 (95% CI, 0.73 to 1.47).
Conclusions and relevance:
In this randomized clinical trial conducted in 18 pediatric intensive care units, a bundled intervention of cardiopulmonary resuscitation training at the point of care and physiologically focused structured debriefing, compared with usual care, did not significantly improve patient survival to hospital discharge with favorable neurologic outcome among pediatric patients who experienced cardiac arrest in the ICU.
Trial registration:
ClinicalTrials.gov Identifier: NCT02837497.
Background
The emergency department witnesses the close functioning of an interdisciplinary team in an unpredictable environment. High stress situations can impact well-being and clinical practice both individually and as a team. Debriefing provides an opportunity for learning, validation, and conversation amongst individuals who may not typically discuss clinical experiences together.
The current study examined how a debriefing program could be designed and implemented in the emergency department so as to help teams and individuals learn from unique, stressful incidents.
Methods
Based on the theory of Workplace Based Learning and a design-based research approach, the evolved nature of a debriefing program implemented in the real-life context of the emergency department was examined. Focus groups were used to collect data. We report the design of the debriefing intervention as well as the program outcomes in terms of provider’s self-perceived roles in the program and program impact on provider’s self-reported clinical practice, as well as the redesign of the program based upon said feedback.
Results
The themes of barriers to debriefing, provision of perspectives, psychological trauma, and nurturing of staff emerged from focus group sessions.
Respondents identified barriers and concerns regarding debriefing, and based upon this information, changes were made to the program, including offering of refresher sessions for debriefing, inclusion of additional staff members in the training, and re-messaging the purpose of the program.
Conclusions
Data from the study reinforced the need to increase the frequency and availability of debriefing didactics along with clarifying staff roles in the program. Future work will examine continued impact on provider practice and influence on departmental culture.
OBJECTIVES
Clinical event debriefing (CED) can improve patient care and outcomes, but little is known about CED across inpatient settings, and participant experiences have not been well described. In this qualitative study, we sought to characterize and compare staff experiences with CED in 2 hospital units, with a goal of generating recommendations for a hospital-wide debriefing program.
METHODS
We conducted 32 semistructured interviews with clinical staff who attended a CED in the previous week. We explored experiences with CED, with a focus on barriers and facilitators. We used content analysis with constant comparative coding to understand priorities identified by participants. We used inductive reasoning to develop a set of CED practice recommendations to match participant priorities.
RESULTS
Three primary themes emerged related to CED barriers and facilitators. (1) Factors affecting attendance: most respondents voiced a need for frontline staff inclusion in CED, but they also cited competing clinical duties and scheduling conflicts as barriers. (2) Factors affecting participant engagement: respondents described factors that influence participant engagement in reflective discussion. They described that the CED leader must cultivate a psychologically safe environment in which participants feel empowered to speak up, free from judgment. (3) Factors affecting learning and systems improvement: respondents emphasized that the CED group should generate a plan for improvement with accountable stakeholders. Collectively, these priorities propose several recommendations for CED practice, including frontline staff inclusion.
CONCLUSIONS
In this study, we propose recommendations for CED that are derived from first-hand participant experiences. Future study will explore implementation of CED practice recommendations.
Statement
The optimal strategy for training cardiopulmonary resuscitation (CPR) for healthcare professionals remains to be determined. This scoping review aimed to describe the emerging evidence for CPR training for healthcare professionals.
We screened 7605 abstracts and included 110 studies in this scoping review on CPR training for healthcare professionals. We assessed the included articles for evidence for the following topics: training duration, retraining intervals, e-learning, virtual reality/augmented reality/gamified learning, instructor-learner ratio, equipment and manikins, other aspects of contextual learning content, feedback devices, and feedback/debriefing. We found emerging evidence supporting the use of low-dose, high-frequency training with e-learning to achieve knowledge, feedback devices to perform high-quality chest compressions, and in situ team simulations with debriefings to improve the performance of provider teams.
Objective:
To describe the use of a postarrest debriefing tool (DBT) within a university teaching hospital and to evaluate user perceptions of the tool.
Design:
Observational study over a 1-year period and associated hospital clinical personnel survey.
Setting:
University teaching hospital.
Interventions:
Qualitative data surrounding the use and utility of the DBT were analyzed, as well as survey results.
Measurements and main results:
Forty-four arrests occurred during the study period. Debriefing was performed after 26 of 44 (59%) cardiopulmonary resuscitation (CPR) events, of which 22 of 26 (85%) were recorded using the DBT and four without the DBT. Return of spontaneous circulation did not significantly affect the use of the DBT (p = 0.753). Most events in which debriefing was not performed occurred outside of business hours (13/18; 72%). The most frequent positive debriefing comments related to cooperation/coordination within the team (22/167; 13%). The most frequent negative debriefing comments concerned equipment issues (36/167; 22%). Of the action points generated, 57% (34/60) were directed at equipment use/availability. Teams reported that emergency drugs were appropriately administered in 21 of 22 (95%) cases. In contrast, closed loop communication was reportedly only used during 6 of 22 (27%) events. The hospital survey response rate was 56 of 338 (17%) clinical staff, of whom 37 of 56 (66%) agreed or strongly agreed that debriefing had improved team performance during CPR. Overall, 33 of 56 (60%) staff felt that the DBT had improved the debriefing process at the hospital. However, 3 of 56 (5%) staff members felt that they were unable to state their opinions in a blame-free environment during debriefing.
Conclusions:
Implementation of a DBT enabled formal identification of strengths and training needs of resuscitation teams, and its implementation was viewed positively by the majority of hospital staff. However, further refinement of the tool and prospective studies evaluating its efficacy in improving outcome are warranted.
Background:
Despite advances in resuscitation care in recent years, it is not clear whether survival and neurologic function after in-hospital cardiac arrest have improved over time.
Methods:
We identified all adults who had an in-hospital cardiac arrest at 374 hospitals in the Get with the Guidelines-Resuscitation registry between 2000 and 2009. Using multivariable regression, we examined temporal trends in risk-adjusted rates of survival to discharge. Additional analyses explored whether trends were due to improved survival during acute resuscitation or postresuscitation care and whether they occurred at the expense of greater neurologic disability in survivors.
Results:
Among 84,625 hospitalized patients with cardiac arrest, 79.3% had an initial rhythm of asystole or pulseless electrical activity, and 20.7% had ventricular fibrillation or pulseless ventricular tachycardia. The proportion of cardiac arrests due to asystole or pulseless electrical activity increased over time (P<0.001 for trend). Risk-adjusted rates of survival to discharge increased from 13.7% in 2000 to 22.3% in 2009 (adjusted rate ratio per year, 1.04; 95% confidence interval [CI], 1.03 to 1.06; P<0.001 for trend). Survival improvement was similar in the two rhythm groups and was due to improvement in both acute resuscitation survival and postresuscitation survival. Rates of clinically significant neurologic disability among survivors decreased over time, with a risk-adjusted rate of 32.9% in 2000 and 28.1% in 2009 (adjusted rate ratio per year, 0.98; 95% CI, 0.97 to 1.00; P=0.02 for trend).
Conclusions:
Both survival and neurologic outcomes after in-hospital cardiac arrest have improved during the past decade at hospitals participating in a large national quality-improvement registry. (Funded by the American Heart Association.).
To investigate the effectiveness of brief bedside cardiopulmonary resuscitation (CPR) training to improve the skill retention of hospital-based pediatric providers. We hypothesized that a low-dose, high-frequency training program (booster training) would improve CPR skill retention.
CPR recording/feedback defibrillators were used to evaluate CPR quality during simulated arrest. Basic life support-certified, hospital-based providers were randomly assigned to 1 of 4 study arms: (1) instructor-only training; (2) automated defibrillator feedback only; (3) instructor training combined with automated feedback; and (4) control (no structured training). Each session (time: 0, 1, 3, and 6 months after training) consisted of a pretraining evaluation (60 seconds), booster training (120 seconds), and a posttraining evaluation (60 seconds). Excellent CPR was defined as chest compression (CC) depth ≥ one-third anterior-posterior chest depth, rate ≥90 and ≤120 CC per minute, ≤20% of CCs with incomplete release (>2500 g), and no flow fraction ≤ 0.30.
Eighty-nine providers were randomly assigned; 74 (83%) completed all sessions. Retention of CPR skills was 2.3 times (95% confidence interval [CI]: 1.1-4.5; P=.02) more likely after 2 trainings and 2.9 times (95% CI: 1.4-6.2; P=.005) more likely after 3 trainings. The automated defibrillator feedback only group had lower retention rates compared with the instructor-only training group (odds ratio: 0.41 [95% CI: 0.17-0.97]; P = .043).
Brief bedside booster CPR training improves CPR skill retention. Our data reveal that instructor-led training improves retention compared with automated feedback training alone. Future studies should investigate whether bedside training improves CPR quality during actual pediatric arrests.
To investigate whether real-time audio and visual feedback during cardiopulmonary resuscitation outside hospital increases the proportion of subjects who achieved prehospital return of spontaneous circulation.
A cluster-randomised trial.
1586 people having cardiac arrest outside hospital in whom resuscitation was attempted by emergency medical services (771 procedures without feedback, 815 with feedback).
Emergency medical services from three sites within the Resuscitation Outcomes Consortium in the United States and Canada.
Real-time audio and visual feedback on cardiopulmonary resuscitation (CPR) provided by the monitor-defibrillator.
Prehospital return of spontaneous circulation after CPR.
Baseline patient and emergency medical service characteristics did not differ between groups. Emergency medical services muted the audible feedback in 14% of cases during the period with feedback. Compared with CPR clusters lacking feedback, clusters assigned to feedback were associated with increased proportion of time in which chest compressions were provided (64% v 66%, cluster-adjusted difference 1.9 (95% CI 0.4 to 3.4)), increased compression depth (38 v 40 mm, adjusted difference 1.6 (0.5 to 2.7)), and decreased proportion of compressions with incomplete release (15% v 10%, adjusted difference -3.4 (-5.2 to -1.5)). However, frequency of prehospital return of spontaneous circulation did not differ according to feedback status (45% v 44%, adjusted difference 0.1% (-4.4% to 4.6%)), nor did the presence of a pulse at hospital arrival (32% v 32%, adjusted difference -0.8 (-4.9 to 3.4)), survival to discharge (12% v 11%, adjusted difference -1.5 (-3.9 to 0.9)), or awake at hospital discharge (10% v 10%, adjusted difference -0.2 (-2.5 to 2.1)).
Real-time visual and audible feedback during CPR altered performance to more closely conform with guidelines. However, these changes in CPR performance were not associated with improvements in return of spontaneous circulation or other clinical outcomes. Trial Registration Clinical Trials NCT00539539.
The following guidelines are an interpretation of the evidence presented in the 2010 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations 1 ). They apply primarily to newly born infants undergoing transition from intrauterine to extrauterine life, but the recommendations are also applicable to neonates who have completed perinatal transition and require resuscitation during the first few weeks to months following birth. Practitioners who resuscitate infants at birth or at any time during the initial hospital admission should consider following these guidelines. For the purposes of these guidelines, the terms newborn and neonate are intended to apply to any infant during the initial hospitalization. The term newly born is intended to apply specifically to an infant at the time of birth. Approximately 10% of newborns require some assistance to begin breathing at birth. Less than 1% require extensive resuscitative measures. 2,3 Although the vast majority of newly born infants do not require intervention to make the transition from intrauterine to extrauterine life, because of the large total number of births, a sizable number will require some degree of resuscitation. Those newly born infants who do not require resuscitation can generally be identified by a rapid assessment of the following 3 characteristics: ● Term gestation? ● Crying or breathing? ● Good muscle tone? If the answer to all 3 of these questions is “yes,” the baby does not need resuscitation and should not be separated from the mother. The baby should be dried, placed skin-to-skin with the mother, and covered with dry linen to maintain temperature. Observation of breathing, activity, and color should be ongoing. If the answer to any of these assessment questions is “no,” the infant should receive one or more of the following 4 categories of action in sequence:
Few data exist on pediatric cardiopulmonary resuscitation (CPR) quality. This study is the first to evaluate actual in-hospital pediatric CPR. We hypothesized that with bedside CPR training and corrective feedback, CPR quality can approach American Heart Association (AHA) targets.
Using CPR recording/feedback defibrillators, quality of CPR was assessed for patients >or=8 years of age who suffered a cardiac arrest in the PICU or emergency department (ED). Before and during the study, a bedside CPR training program was initiated.
Between October 2006 and February 2008, twenty events in 18 patients met inclusion criteria and resulted in 36749 evaluable chest compressions (CCs) during 392.3 minutes of arrest. CCs were shallow (<38 mm or <1.5 in) in 27.2% (9998 of 36749), with excessive residual leaning force (>or=2500 g) in 23.4% (8611 of 36749). Segmental analysis of the first 5 minutes of the events demonstrated that shallow CCs and excessive residual leaning force were less prevalent during the first 5 minutes. AHA targets were not achieved for CC rate in 62 (43.1%) of 144 segments, CC depth in 52 (36.1%) of 144 segments, and residual leaning force in 53 (36.8%) of 144 segments.
This prospective, observational study demonstrates feasibility of monitoring in-hospital pediatric CPR. Even with bedside CPR retraining and corrective audiovisual feedback, CPR quality frequently did not meet AHA targets. Importantly, no flow fraction target of 10% was achieved. Future studies should investigate novel educational methods and targeted feedback technologies.
The health and policy implications of regional variation in incidence and outcome of out-of-hospital cardiac arrest remain to be determined.
To evaluate whether cardiac arrest incidence and outcome differ across geographic regions.
Prospective observational study (the Resuscitation Outcomes Consortium) of all out-of-hospital cardiac arrests in 10 North American sites (8 US and 2 Canadian) from May 1, 2006, to April 30, 2007, followed up to hospital discharge, and including data available as of June 28, 2008. Cases (aged 0-108 years) were assessed by organized emergency medical services (EMS) personnel, did not have traumatic injury, and received attempts at external defibrillation or chest compressions or resuscitation was not attempted. Census data were used to determine rates adjusted for age and sex.
Incidence rate, mortality rate, case-fatality rate, and survival to discharge for patients assessed or treated by EMS personnel or with an initial rhythm of ventricular fibrillation.
Among the 10 sites, the total catchment population was 21.4 million, and there were 20,520 cardiac arrests. A total of 11,898 (58.0%) had resuscitation attempted; 2729 (22.9% of treated) had initial rhythm of ventricular fibrillation or ventricular tachycardia or rhythms that were shockable by an automated external defibrillator; and 954 (4.6% of total) were discharged alive. The median incidence of EMS-treated cardiac arrest across sites was 52.1 (interquartile range [IQR], 48.0-70.1) per 100,000 population; survival ranged from 3.0% to 16.3%, with a median of 8.4% (IQR, 5.4%-10.4%). Median ventricular fibrillation incidence was 12.6 (IQR, 10.6-5.2) per 100,000 population; survival ranged from 7.7% to 39.9%, with a median of 22.0% (IQR, 15.0%-24.4%), with significant differences across sites for incidence and survival (P<.001).
In this study involving 10 geographic regions in North America, there were significant and important regional differences in out-of-hospital cardiac arrest incidence and outcome.
The survival benefit of well-performed cardiopulmonary resuscitation (CPR) is well-documented, but little objective data exist regarding actual CPR quality during cardiac arrest. Recent studies have challenged the notion that CPR is uniformly performed according to established international guidelines.
To measure multiple parameters of in-hospital CPR quality and to determine compliance with published American Heart Association and international guidelines.
A prospective observational study of 67 patients who experienced in-hospital cardiac arrest at the University of Chicago Hospitals, Chicago, Ill, between December 11, 2002, and April 5, 2004. Using a monitor/defibrillator with novel additional sensing capabilities, the parameters of CPR quality including chest compression rate, compression depth, ventilation rate, and the fraction of arrest time without chest compressions (no-flow fraction) were recorded.
Adherence to American Heart Association and international CPR guidelines.
Analysis of the first 5 minutes of each resuscitation by 30-second segments revealed that chest compression rates were less than 90/min in 28.1% of segments. Compression depth was too shallow (defined as <38 mm) for 37.4% of compressions. Ventilation rates were high, with 60.9% of segments containing a rate of more than 20/min. Additionally, the mean (SD) no-flow fraction was 0.24 (0.18). A 10-second pause each minute of arrest would yield a no-flow fraction of 0.17. A total of 27 patients (40.3%) achieved return of spontaneous circulation and 7 (10.4%) were discharged from the hospital.
In this study of in-hospital cardiac arrest, the quality of multiple parameters of CPR was inconsistent and often did not meet published guideline recommendations, even when performed by well-trained hospital staff. The importance of high-quality CPR suggests the need for rescuer feedback and monitoring of CPR quality during resuscitation efforts.
Cardiac arrests in adults are often due to ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT), which are associated with better outcomes than asystole or pulseless electrical activity (PEA). Cardiac arrests in children are typically asystole or PEA.
To test the hypothesis that children have relatively fewer in-hospital cardiac arrests associated with VF or pulseless VT compared with adults and, therefore, worse survival outcomes.
A prospective observational study from a multicenter registry (National Registry of Cardiopulmonary Resuscitation) of cardiac arrests in 253 US and Canadian hospitals between January 1, 2000, and March 30, 2004. A total of 36,902 adults (> or =18 years) and 880 children (<18 years) with pulseless cardiac arrests requiring chest compressions, defibrillation, or both were assessed. Cardiac arrests occurring in the delivery department, neonatal intensive care unit, and in the out-of-hospital setting were excluded.
Survival to hospital discharge.
The rate of survival to hospital discharge following pulseless cardiac arrest was higher in children than adults (27% [236/880] vs 18% [6485/36,902]; adjusted odds ratio [OR], 2.29; 95% confidence interval [CI], 1.95-2.68). Of these survivors, 65% (154/236) of children and 73% (4737/6485) of adults had good neurological outcome. The prevalence of VF or pulseless VT as the first documented pulseless rhythm was 14% (120/880) in children and 23% (8361/36,902) in adults (OR, 0.54; 95% CI, 0.44-0.65; P<.001). The prevalence of asystole was 40% (350) in children and 35% (13 024) in adults (OR, 1.20; 95% CI, 1.10-1.40; P = .006), whereas the prevalence of PEA was 24% (213) in children and 32% (11,963) in adults (OR, 0.67; 95% CI, 0.57-0.78; P<.001). After adjustment for differences in preexisting conditions, interventions in place at time of arrest, witnessed and/or monitored status, time to defibrillation of VF or pulseless VT, intensive care unit location of arrest, and duration of cardiopulmonary resuscitation, only first documented pulseless arrest rhythm remained significantly associated with differential survival to discharge (24% [135/563] in children vs 11% [2719/24,987] in adults with asystole and PEA; adjusted OR, 2.73; 95% CI, 2.23-3.32).
In this multicenter registry of in-hospital cardiac arrest, the first documented pulseless arrest rhythm was typically asystole or PEA in both children and adults. Because of better survival after asystole and PEA, children had better outcomes than adults despite fewer cardiac arrests due to VF or pulseless VT.
Age is an important determinant of outcome from adult cardiac arrests but has not been identified previously as an important factor in pediatric cardiac arrests except among premature infants. Chest compressions can result in more effective blood flow during cardiac arrest in an infant than an older child or adult because of increased chest wall compliance. We, therefore, hypothesized that survival from cardiac arrest would be better among infants than older children.
We evaluated 464 pediatric ICU arrests from the National Registry of Cardiopulmonary Resuscitation from 2000 to 2002. NICU cardiac arrests were excluded. Data from each arrest include >200 variables describing facility, patient, prearrest, arrest intervention, outcome, and quality improvement data. Age was categorized as newborn (<1 month; N = 62), infant (1 month to <1 year; N = 105), younger child (1 year to <8 years; N = 90), and older child (8 years to <21 years; N = 207). Multivariable logistic regression was performed to examine the association between age and survival.
Overall survival was 22%, with 27% of newborns, 36% of infants, 19% of younger children and 16% of older children surviving to hospital discharge. Newborns and infants demonstrated double and triple the odds of surviving to hospital discharge from a cardiac arrest in an intensive care setting when compared with older children. When potential confounders were controlled, newborns increased their advantage to almost fivefold, while infants maintained their survival advantage to older children.
Survival from pediatric ICU cardiac arrest is age dependent. Newborns and infants have better survival rates even after adjusting for potential confounding variables.
Cardiopulmonary resuscitation (CPR) quality during actual cardiac arrest has been found to be deficient in several recent investigations. We hypothesized that real-time feedback during CPR would improve the performance of chest compressions and ventilations during in-hospital cardiac arrest.
An investigational monitor/defibrillator with CPR-sensing and feedback capabilities was used during in-hospital cardiac arrests from December 2004 to December 2005. Chest compression and ventilation characteristics were recorded and quantified for the first 5 min of resuscitation and compared to a baseline cohort of arrest episodes without feedback, from December 2002 to April 2004.
Data from 55 resuscitation episodes in the baseline pre-intervention group were compared to 101 resuscitations in the feedback intervention group. There was a trend toward improvement in the mean values of CPR variables in the feedback group with a statistically significant narrowing of CPR variable distributions including chest compression rate (104+/-18 to 100+/-13 min(-1); test of means, p=0.16; test of variance, p=0.003) and ventilation rate (20+/-10 to 18+/-8 min(-1); test of means, p=0.12; test of variance, p=0.04). There were no statistically significant differences between the groups in either return of spontaneous circulation or survival to hospital discharge.
Real-time CPR-sensing and feedback technology modestly improved the quality of CPR during in-hospital cardiac arrest, and may serve as a useful adjunct for rescuers during resuscitation efforts. However, feedback specifics should be optimized for maximal benefit and additional studies will be required to assess whether gains in CPR quality translate to improvements in survival.
Expert guidelines advocate defibrillation within 2 minutes after an in-hospital cardiac arrest caused by ventricular arrhythmia. However, empirical data on the prevalence of delayed defibrillation in the United States and its effect on survival are limited.
We identified 6789 patients who had cardiac arrest due to ventricular fibrillation or pulseless ventricular tachycardia at 369 hospitals participating in the National Registry of Cardiopulmonary Resuscitation. Using multivariable logistic regression, we identified characteristics associated with delayed defibrillation. We then examined the association between delayed defibrillation (more than 2 minutes) and survival to discharge after adjusting for differences in patient and hospital characteristics.
The overall median time to defibrillation was 1 minute (interquartile range, <1 to 3 minutes); delayed defibrillation occurred in 2045 patients (30.1%). Characteristics associated with delayed defibrillation included black race, noncardiac admitting diagnosis, and occurrence of cardiac arrest at a hospital with fewer than 250 beds, in an unmonitored hospital unit, and during after-hours periods (5 p.m. to 8 a.m. or weekends). Delayed defibrillation was associated with a significantly lower probability of surviving to hospital discharge (22.2%, vs. 39.3% when defibrillation was not delayed; adjusted odds ratio, 0.48; 95% confidence interval, 0.42 to 0.54; P<0.001). In addition, a graded association was seen between increasing time to defibrillation and lower rates of survival to hospital discharge for each minute of delay (P for trend <0.001).
Delayed defibrillation is common and is associated with lower rates of survival after in-hospital cardiac arrest.
Recent investigations have documented poor cardiopulmonary resuscitation (CPR) performance in clinical practice. We hypothesized that a debriefing intervention using CPR quality data from actual in-hospital cardiac arrests (resuscitation with actual performance integrated debriefing [RAPID]) would improve CPR performance and initial patient survival.
Internal medicine residents at a university hospital attended weekly debriefing sessions of the prior week's resuscitations, between March 2006 and February 2007, reviewing CPR performance transcripts obtained from a CPR-sensing and feedback-enabled defibrillator. Objective metrics of CPR performance and initial return of spontaneous circulation were compared with a historical cohort in which a similar feedback-delivering defibrillator was used but without RAPID.
Cardiopulmonary resuscitation quality and outcome data from 123 patients resuscitated during the intervention period were compared with 101 patients in the baseline cohort. Compared with the control period, the mean (SD) ventilation rate decreased (13 [7]/min vs 18 [8]/min; P < .001) and compression depth increased (50 [10] vs 44 [10] mm; P = .001), among other CPR improvements. These changes correlated with an increase in the rate of return of spontaneous circulation in the RAPID group (59.4% vs 44.6%; P = .03) but no change in survival to discharge (7.4% vs 8.9%; P = .69).
The combination of RAPID and real-time audiovisual feedback improved CPR quality compared with the use of feedback alone and was associated with an increased rate of return of spontaneous circulation. Cardiopulmonary resuscitation sensing and recording devices allow for methods of debriefing that were previously available only for simulation-based education; such methods have the potential to fundamentally alter resuscitation training and improve patient outcomes.
clinicaltrials.gov Identifier: NCT00228293.
Background : Incomplete chest recoil during cardiopulmonary resuscitation (CPR) (ie, leaning on the chest during the decompression phase) is purported to decrease venous return, and thereby decrease forward blood flow.
Aim To determine the effect of 10% and 20% lean on hemodynamics during piglet CPR.
Methods : 10 piglets (10.7±1.2 kg) were anesthetized with isoflurane and instrumented with micromanometer-tipped catheters in the right atrium (RA) and aorta (Ao). After induction of ventricular fibrillation, CPR was provided in three-minute epochs with no lean, 10% lean, or 20% lean while aortic systolic pressure (AoS) was targeted at 80–90 mmHg. Because the mean force to attain 80 –90 mm Hg AoS was 18 kg in preliminary studies, 10% and 20% lean were provided as 1.8 and 3.6 kg weights on the chest, respectively. Left ventricular myocardial blood flow (MBF) and cardiac index (CI) were determined by fluorescent, color-microsphere technique. Statistics: paired t -test and repeated measurement ANOVA for parametric, Wilcoxon Rank Sum Test and Friedman’s ANOVA for non-parametric data.
Results : 10% and 20% lean resulted in higher right atrial diastolic pressure (RAD) and lower coronary perfusion pressure (CPP) than no lean. Hemodynamics were not different with 10% lean vs. 20% lean. Mean 10%–20% lean resulted in substantially lower MBF and CI than no lean (Table ).
Conclusions : 10–20% leaning during CPR increases RAD, decreases CPP, and substantially decreases MBF and CI.
Table
Outcome after cardiac arrest and cardiopulmonary resuscitation is dependent on critical interventions, particularly early defibrillation, effective chest compressions, and advanced life support. Utstein-style definitions and reporting templates have been used extensively in published studies of cardiac arrest, which has led to greater understanding of the elements of resuscitation practice and progress toward international consensus on science and resuscitation guidelines. Despite the development of Utstein templates to standardize research reports of cardiac arrest, international registries have yet to be developed. In April 2002, a task force of the International Liaison Committee on Resuscitation (ILCOR) met in Melbourne, Australia, to review worldwide experience with the Utstein definitions and reporting templates. The task force revised the core reporting template and definitions by consensus. Care was taken to build on previous definitions, changing data elements and operational definitions only on the basis of published data and experience derived from those registries that have used Utstein-style reporting. Attention was focused on decreasing the complexity of the existing templates and addressing logistical difficulties in collecting specific core and supplementary (ie, essential and desirable) data elements recommended by previous Utstein consensus conferences. Inconsistencies in terminology between in-hospital and out-of-hospital Utstein templates were also addressed. The task force produced a reporting tool for essential data that can be used for both quality improvement (registries) and research reports and that should be applicable to both adults and children. The revised and simplified template includes practical and succinct operational definitions. It is anticipated that the revised template will enable better and more accurate completion of all reports of cardiac arrest and resuscitation attempts. Problems with data definition, collection, linkage, confidentiality, management, and registry implementation are acknowledged and potential solutions offered. Uniform collection and tracking of registry data should enable better continuous quality improvement within every hospital, emergency medical services system, and community.
Purpose of review:
Evidence of suboptimal cardiopulmonary resuscitation (CPR) delivery in practice has driven interest in strategies to improve CPR quality. Early data suggest that debriefing may be an effective strategy. In this review, we analyse types of debriefing and the evidence to support their usage.
Recent findings:
There is a general lack of standardization in terminology and methods used for debriefing that limits evaluation. Debriefing interventions generally take two different formats. Hot debriefing is one where individuals or teams are provided with debriefing immediately after the event. Although perhaps the most widely used and easiest to implement, research evidence for its effectiveness is scant. Cold debriefing, where individuals or teams are provided with feedback sometime after the event, is associated with improvements in process and patient outcomes. Such feedback usually involves the use of objective performance data, such as defibrillator downloads or videotape records. Before and after cohort studies have found that both verbal debriefing in groups and individual written feedback seem to be associated with an improvement in performance.
Summary:
Debriefing is a useful strategy to improve resuscitation performance, but the optimal delivery method remains unclear. Future high-quality research is required to identify the most effective form of debriefing.
Background:
Despite ongoing efforts to improve the quality of pediatric resuscitation, it remains unknown whether survival in children with in-hospital cardiac arrest has improved.
Methods and results:
Between 2000 and 2009, we identified children (<18 years of age) with an in-hospital cardiac arrest at hospitals with >3 years of participation and >5 cases annually within the national Get With The Guidelines-Resuscitation registry. Multivariable logistic regression was used to examine temporal trends in survival to discharge. We also explored whether trends in survival were attributable to improvement in acute resuscitation or postresuscitation care and examined trends in neurological disability among survivors. Among 1031 children at 12 hospitals, the initial cardiac arrest rhythm was asystole and pulseless electrical activity in 874 children (84.8%) and ventricular fibrillation and pulseless ventricular tachycardia in 157 children (15.2%), with an increase in cardiac arrests due to pulseless electrical activity over time (P for trend <0.001). Risk-adjusted rates of survival to discharge increased from 14.3% in 2000 to 43.4% in 2009 (adjusted rate ratio per year, 1.08; 95% confidence interval, 1.01-1.16; P for trend=0.02). Improvement in survival was driven largely by an improvement in acute resuscitation survival (risk-adjusted rates: 42.9% in 2000, 81.2% in 2009; adjusted rate ratio per year: 1.04; 95% confidence interval, 1.01-1.08; P for trend=0.006). Moreover, survival trends were not accompanied by higher rates of neurological disability among survivors over time (unadjusted P for trend=0.32), suggesting an overall increase in the number of survivors without neurological disability over time.
Conclusions:
Rates of survival to hospital discharge in children with in-hospital cardiac arrests have improved over the past decade without higher rates of neurological disability among survivors.
Aim:
To evaluate the association between cardiopulmonary resuscitation (CPR) quality and hemodynamic measurements during in-hospital pediatric cardiac arrest. We hypothesized that AHA recommended CPR rate and depth targets would be associated with systolic blood pressures≥80mmHg and diastolic blood pressures≥30mmHg.
Methods:
In children and adolescents <18 years of age who suffered a cardiac arrest with an invasive arterial catheter in place, a CPR monitoring defibrillator collected CPR data which was synchronized to arterial blood pressure (BP) tracings. Chest compression (CC) depths were corrected for mattress deflection. Generalized least squares regression estimated the association between BP and CPR quality, treated as continuous variables. Mixed-effects logistic regression estimated the association between systolic BP≥80mmHg/diastolic BP≥30mmHg and the AHA targets of depth≥38mm and/or rate≥100/min.
Results:
Nine arrests resulted in 4156 CCs. The median mattress corrected depth was 32mm (IQR 28-38); median rate was 111CC/min (IQR 103-120). AHA depth was achieved in 1090/4156 (26.2%) CCs; rate in 3441 (83.7%). Systolic BP≥80mmHg was attained in 2516/4156 (60.5%) compressions; diastolic≥30mmHg in 2561/4156 (61.6%). A rate≥100/min was associated with systolic BP≥80mmHg (OR 1.32; CI(95) 1.04, 1.66; p=0.02) and diastolic BP≥30mmHg (OR 2.15; CI(95) 1.65, 2.80; p<0.001). Exceeding both (rate≥100/min and depth≥38mm) was associated with systolic BP≥80mmHg (OR 2.02; CI(95) 1.45, 2.82; p<0.001) and diastolic BP≥30mmHg (OR 1.48; CI(95) 1.01, 2.15; p=0.042).
Conclusions:
AHA quality targets (rate≥100/min and depth≥38mm) were associated with systolic BPs≥80mmHg and diastolic BPs≥30mmHg during CPR in children.
Background:
During in-hospital cardiac arrests, how long resuscitation attempts should be continued before termination of efforts is unknown. We investigated whether duration of resuscitation attempts varies between hospitals and whether patients at hospitals that attempt resuscitation for longer have higher survival rates than do those at hospitals with shorter durations of resuscitation efforts.
Methods:
Between 2000 and 2008, we identified 64,339 patients with cardiac arrests at 435 US hospitals within the Get With The Guidelines—Resuscitation registry. For each hospital, we calculated the median duration of resuscitation before termination of efforts in non-survivors as a measure of the hospital's overall tendency for longer attempts. We used multilevel regression models to assess the association between the length of resuscitation attempts and risk-adjusted survival. Our primary endpoints were immediate survival with return of spontaneous circulation during cardiac arrest and survival to hospital discharge.
Findings:
31,198 of 64,339 (48·5%) patients achieved return of spontaneous circulation and 9912 (15·4%) survived to discharge. For patients achieving return of spontaneous circulation, the median duration of resuscitation was 12 min (IQR 6-21) compared with 20 min (14-30) for non-survivors. Compared with patients at hospitals in the quartile with the shortest median resuscitation attempts in non-survivors (16 min [IQR 15-17]), those at hospitals in the quartile with the longest attempts (25 min [25-28]) had a higher likelihood of return of spontaneous circulation (adjusted risk ratio 1·12, 95% CI 1·06-1·18; p<0·0001) and survival to discharge (1·12, 1·02-1·23; 0·021).
Interpretation:
Duration of resuscitation attempts varies between hospitals. Although we cannot define an optimum duration for resuscitation attempts on the basis of these observational data, our findings suggest that efforts to systematically increase the duration of resuscitation could improve survival in this high-risk population.

Guidelines for cardiopulmonary resuscitation recommend a chest compression rate of at least 100 compressions per minute. Animal and human studies have reported that blood flow is greatest with chest compression rates near 120/min, but few have reported rates used during out-of-hospital (OOH) cardiopulmonary resuscitation or the relationship between rate and outcome. The purpose of this study was to describe chest compression rates used by emergency medical services providers to resuscitate patients with OOH cardiac arrest and to determine the relationship between chest compression rate and outcome.
Included were patients aged ≥ 20 years with OOH cardiac arrest treated by emergency medical services providers participating in the Resuscitation Outcomes Consortium. Data were abstracted from monitor-defibrillator recordings during cardiopulmonary resuscitation. Multiple logistic regression analysis assessed the association between chest compression rate and outcome. From December 2005 to May 2007, 3098 patients with OOH cardiac arrest were included in this study. Mean age was 67 ± 16 years, and 8.6% survived to hospital discharge. Mean compression rate was 112 ± 19/min. A curvilinear association between chest compression rate and return of spontaneous circulation was found in cubic spline models after multivariable adjustment (P=0.012). Return of spontaneous circulation rates peaked at a compression rate of ≈ 125/min and then declined. Chest compression rate was not significantly associated with survival to hospital discharge in multivariable categorical or cubic spline models.
Chest compression rate was associated with return of spontaneous circulation but not with survival to hospital discharge in OOH cardiac arrest.
Objective:
Globally, one third of deaths each year are from cardiovascular diseases, yet no strong evidence supports any specific method of CPR instruction in a resource-limited setting. We hypothesized that both existing and novel CPR training programs significantly impact skills of hospital-based healthcare providers (HCP) in Botswana.
Methods:
HCP were prospectively randomized to 3 training groups: instructor led, limited instructor with manikin feedback, or self-directed learning. Data was collected prior to training, immediately after and at 3 and 6 months. Excellent CPR was prospectively defined as having at least 4 of 5 characteristics: depth, rate, release, no flow fraction, and no excessive ventilation. GEE was performed to account for within subject correlation.
Results:
Of 214 HCP trained, 40% resuscitate ≥ 1/month, 28% had previous formal CPR training, and 65% required additional skills remediation to pass using AHA criteria. Excellent CPR skill acquisition was significant (infant: 32% vs. 71%, p<0.01; adult 28% vs. 48%, p<0.01). Infant CPR skill retention was significant at 3 (39% vs. 70%, p<0.01) and 6 months (38% vs. 67%, p<0.01), and adult CPR skills were retained to 3 months (34% vs. 51%, p=0.02). On multivariable analysis, low cognitive score and need for skill remediation, but not instruction method, impacted CPR skill performance.
Conclusions:
HCP in resource-limited settings resuscitate frequently, with little CPR training. Using existing training, HCP acquire and retain skills, yet often require remediation. Novel techniques with increased student: instructor ratio and feedback manikins were not different compared to traditional instruction.
Debriefing is a process involving the active participation of learners, guided by a facilitator or instructor whose primary goal is to identify and close gaps in knowledge and skills. A review of existing research and a process for identifying future opportunities was undertaken.
A selective critical review of the literature on debriefing in simulation-based education was done. An iterative process of analysis, gathering input from audience participants, and consensus-based synthesis was conducted.
Research is sparse and limited in presentation for all important topic areas where debriefing is a primary variable. The importance of a format for reporting data on debriefing in a research context was realized and a "who, when, where, what, why" approach was proposed. Also, a graphical representation of the characteristics of debriefing studies was developed (Sim-PICO) to help guide simulation researchers in appropriate experimental design and reporting.
A few areas of debriefing practice where obvious gaps that deserve study were identified, such as comparing debriefing techniques, comparing trained versus untrained debriefers, and comparing the effect of different debriefing venues and times. A model for publication of research data was developed and presented which should help researchers clarify methodology in future work.
Our primary objective was to describe and determine the feasibility of implementing a care environment targeted pediatric post-cardiac arrest debriefing program. A secondary objective was to evaluate the usefulness of debriefing content items. We hypothesized that a care environment targeted post-cardiac arrest debriefing program would be feasible, well-received, and result in improved self-reported knowledge, confidence and performance of pediatric providers.
Physician-led multidisciplinary pediatric post-cardiac arrest debriefings were conducted using data from CPR recording defibrillators/central monitors followed by a semi-quantitative survey. Eight debriefing content elements divided, a priori, into physical skill (PS) related and cognitive skill (CS) related categories were evaluated on a 5-point Likert scale to determine those most useful (5-point Likert scale: 1=very useful/5=not useful). Summary scores evaluated the impact on providers' knowledge, confidence, and performance.
Between June 2010 and May 2011, 6 debriefings were completed. Thirty-four of 50 (68%) front line care providers attended the debriefings and completed surveys. All eight content elements were rated between useful to very useful (Median 1; IQR 1-2). PS items scored higher than CS items to improve knowledge (Median: 2 (IQR 1-3) vs. 1 (IQR 0-2); p<0.02) and performance (Median: 2 (IQR 1-3) vs. 1 (IQR 0-1); p<0.01).
A novel care environment targeted pediatric post-cardiac arrest pediatric debriefing program is feasible and useful for providers regardless of their participation in the resuscitation. Physical skill related elements were rated more useful than cognitive skill related elements for knowledge and performance.
The 2010 international guidelines for cardiopulmonary resuscitation recently recommended an increase in the minimum compression depth from 38 to 50 mm, although there are limited human data to support this. We sought to study patterns of cardiopulmonary resuscitation compression depth and their associations with patient outcomes in out-of-hospital cardiac arrest cases treated by the 2005 guideline standards.
Prospective cohort.
Seven U.S. and Canadian urban regions.
We studied emergency medical services treated out-of-hospital cardiac arrest patients from the Resuscitation Outcomes Consortium Epistry-Cardiac Arrest for whom electronic cardiopulmonary resuscitation compression depth data were available, from May 2006 to June 2009.
We calculated anterior chest wall depression in millimeters and the period of active cardiopulmonary resuscitation (chest compression fraction) for each minute of cardiopulmonary resuscitation. We controlled for covariates including compression rate and calculated adjusted odds ratios for any return of spontaneous circulation, 1-day survival, and hospital discharge.
We included 1029 adult patients from seven U.S. and Canadian cities with the following characteristics: Mean age 68 yrs; male 62%; bystander witnessed 40%; bystander cardiopulmonary resuscitation 37%; initial rhythms: Ventricular fibrillation/ventricular tachycardia 24%, pulseless electrical activity 16%, asystole 48%, other nonshockable 12%; outcomes: Return of spontaneous circulation 26%, 1-day survival 18%, discharge 5%. For all patients, median compression rate was 106 per minute, median compression fraction 0.65, and median compression depth 37.3 mm with 52.8% of cases having depth <38 mm and 91.6% having depth <50 mm. We found an inverse association between depth and compression rate ( p < .001). Adjusted odds ratios for all depth measures (mean values, categories, and range) showed strong trends toward better outcomes with increased depth for all three survival measures.
We found suboptimal compression depth in half of patients by 2005 guideline standards and almost all by 2010 standards as well as an inverse association between compression depth and rate. We found a strong association between survival outcomes and increased compression depth but no clear evidence to support or refute the 2010 recommendations of >50 mm. Although compression depth is an important component of cardiopulmonary resuscitation and should be measured routinely, the most effective depth is currently unknown.
The incidence and incidence over time of cardiac arrest in hospitalized patients is unknown. We sought to estimate the event rate and temporal trends of adult inhospital cardiac arrest treated with a resuscitation response.
Three approaches were used to estimate the inhospital cardiac arrest event rate. First approach: calculate the inhospital cardiac arrest event rate at hospitals (n = 433) in the Get With The Guidelines-Resuscitation registry, years 2003-2007, and multiply this by U.S. annual bed days. Second approach: use the Get With The Guidelines-Resuscitation inhospital cardiac arrest event rate to develop a regression model (including hospital demographic, geographic, and organizational factors), and use the model coefficients to calculate predicted event rates for acute care hospitals (n = 5445) responding to the American Hospital Association survey. Third approach: classify acute care hospitals into groups based on academic, urban, and bed size characteristics, and determine the average event rate for Get With The Guidelines-Resuscitation hospitals in each group, and use weighted averages to calculate the national inhospital cardiac arrest rate. Annual event rates were calculated to estimate temporal trends.
Get With The Guidelines-Resuscitation registry.
Adult inhospital cardiac arrest with a resuscitation response.
The mean adult treated inhospital cardiac arrest event rate at Get With The Guidelines-Resuscitation hospitals was 0.92/1000 bed days (interquartile range 0.58 to 1.2/1000). In hospitals (n = 150) contributing data for all years of the study period, the event rate increased from 2003 to 2007. With 2.09 million annual U.S. bed days, we estimated 192,000 inhospital cardiac arrests throughout the United States annually. Based on the regression model, extrapolating Get With The Guidelines-Resuscitation hospitals to hospitals participating in the American Hospital Association survey projected 211,000 annual inhospital cardiac arrests. Using weighted averages projected 209,000 annual U.S. inhospital cardiac arrests.
There are approximately 200,000 treated cardiac arrests among U.S. hospitalized patients annually, and this rate may be increasing. This is important for understanding the burden of inhospital cardiac arrest and developing strategies to improve care for hospitalized patients.
Perishock pauses are pauses in chest compressions before and after defibrillatory shock. We examined the relationship between perishock pauses and survival to hospital discharge.
We included out-of-hospital cardiac arrest patients in the Resuscitation Outcomes Consortium Epistry-Cardiac Arrest who suffered arrest between December 2005 and June 2007, presented with a shockable rhythm (ventricular fibrillation or pulseless ventricular tachycardia), and had cardiopulmonary resuscitation process data for at least 1 shock (n=815). We used multivariable logistic regression to determine the association between survival and perishock pauses. In an analysis adjusted for Utstein predictors of survival, the odds of survival were significantly lower for patients with preshock pause ≥20 seconds (odds ratio, 0.47; 95% confidence interval, 0.27 to 0.82) and perishock pause ≥40 seconds (odds ratio, 0.54; 95% confidence interval, 0.31 to 0.97) compared with patients with preshock pause <10 seconds and perishock pause <20 seconds. Postshock pause was not independently associated with a significant change in the odds of survival. Log-linear modeling depicted a decrease in survival to hospital discharge of 18% and 14% for every 5-second increase in both preshock and perishock pause interval (up to 40 and 50 seconds, respectively), with no significant association noted with changes in the postshock pause interval.
In patients with cardiac arrest presenting in a shockable rhythm, longer perishock and preshock pauses were independently associated with a decrease in survival to hospital discharge. The impact of preshock pause on survival suggests that refinement of automatic defibrillator software and paramedic education to minimize preshock pause delays may have a significant impact on survival.
Vasopressors administered IV late during resuscitation efforts fail to improve survival. Intraosseous (IO) access can provide a route for earlier administration. We hypothesized that IO epinephrine after 1 minute of cardiopulmonary resuscitation (CPR) (an "optimal" IO scenario) after 10 minutes of untreated ventricular fibrillation (VF) cardiac arrest would improve outcome in comparison with either IV epinephrine after 8 minutes of CPR (a "realistic" IV scenario) or placebo controls with no epinephrine.
Thirty swine were randomized to IO epinephrine, IV epinephrine, or placebo. Important outcomes included return of spontaneous circulation (ROSC), 24-hour survival, and 24-hour survival with good neurological outcome (cerebral performance category 1).
ROSC after 10 minutes of untreated VF was uncommon without administration of epinephrine (1 of 10), whereas ROSC was nearly universal with IO epinephrine or delayed IV epinephrine (10 of 10 and 9 of 10, respectively; P = 0.001 for either versus placebo). Twenty-four hour survival was substantially more likely after IO epinephrine than after delayed IV epinephrine (10 of 10 vs. 4 of 10, P = 0.001). None of the placebo group survived at 24 hours. Survival with good neurological outcome was more likely after IO epinephrine than after placebo (6 of 10 vs. 0 of 10, P = 0.011), and only 3 of 10 survived with good neurological outcome in the delayed IV epinephrine group (not significant versus either IO or placebo).
In this swine model of prolonged VF cardiac arrest, epinephrine administration during CPR improved outcomes. In addition, early IO epinephrine improved outcomes in comparison with delayed IV epinephrine.
Resuscitation guidelines recommend rescue ventilations consist of tidal volumes 7-10 ml/kg. Changes in thoracic impedance (ΔTI) measured using defibrillator electrode pads to detect and guide rescue ventilations have not been studied in children.
We hypothesized that ΔTI measured via standard anterior-apical (AA) position can accurately detect ventilations with volume > 7 ml/kg in children. We also compared standard AA position with alternative anterior-posterior (AP) position.
IRB-approved, prospective, observational study of sedated, subjects (6 months to 17 years) on conventional mechanical ventilation. Thoracic impedance (TI) was obtained via Philips MRx defibrillator with standard electrode pads for 5 min each in AA and AP positions. Ventilations were simultaneously measured by pneumotachometer (Novametrix CO(2)SMO Plus).
Twenty-eight subjects (median 4 years, IQR 1.7-9 years; median 16.3 kg, IQR 10.5-39 kg) were enrolled. Data were available for 21 episodes in AA position and 22 episodes in AP position, with paired AA and AP data available for 18. For ventilations with volume < 7 ml/kg, the defibrillator algorithm detected 80.0% for both AA and AP (p=0.99). For ventilations ≥ 7 ml/kg, detection was 95.1% for AA and 95.7% for AP (p=0.38).
Changes in thoracic impedance obtained via defibrillator pads can accurately detect ventilations above 7 ml/kg in stable, mechanically ventilated children, corresponding to rescue ventilations recommended during CPR. Both AA and AP pad positions were less sensitive to detect smaller volumes (< 7 ml/kg) than higher volumes (≥ 7 ml/kg), suggesting that shallow ventilations during CPR might be missed. There were no differences in impedance measurements between standard AA pad position and commonly used alternative AP pad position.
To investigate the effectiveness of brief bedside "booster" cardiopulmonary resuscitation (CPR) training to improve CPR guideline compliance of hospital-based pediatric providers.
Prospective, randomized trial.
General pediatric wards at Children's Hospital of Philadelphia.
Sixty-nine Basic Life Support-certified hospital-based providers.
CPR recording/feedback defibrillators were used to evaluate CPR quality during simulated pediatric arrest. After a 60-sec pretraining CPR evaluation, subjects were randomly assigned to one of three instructional/feedback methods to be used during CPR booster training sessions. All sessions (training/CPR manikin practice) were of equal duration (2 mins) and differed only in the method of corrective feedback given to participants during the session. The study arms were as follows: 1) instructor-only training; 2) automated defibrillator feedback only; and 3) instructor training combined with automated feedback.
Before instruction, 57% of the care providers performed compressions within guideline rate recommendations (rate >90 min(-1) and <120 min(-1)); 71% met minimum depth targets (depth, >38 mm); and 36% met overall CPR compliance (rate and depth within targets). After instruction, guideline compliance improved (instructor-only training: rate 52% to 87% [p .01], and
