Article: Types and Origins of Diagnostic Errors in Primary Care Settings.
[show abstract] [hide abstract]
ABSTRACT: IMPORTANCE Diagnostic errors are an understudied aspect of ambulatory patient safety. OBJECTIVES To determine the types of diseases missed and the diagnostic processes involved in cases of confirmed diagnostic errors in primary care settings and to determine whether record reviews could shed light on potential contributory factors to inform future interventions. DESIGN We reviewed medical records of diagnostic errors detected at 2 sites through electronic health record-based triggers. Triggers were based on patterns of patients' unexpected return visits after an initial primary care index visit. SETTING A large urban Veterans Affairs facility and a large integrated private health care system. PARTICIPANTS Our study focused on 190 unique instances of diagnostic errors detected in primary care visits between October 1, 2006, and September 30, 2007. MAIN OUTCOME MEASURES Through medical record reviews, we collected data on presenting symptoms at the index visit, types of diagnoses missed, process breakdowns, potential contributory factors, and potential for harm from errors. RESULTS In 190 cases, a total of 68 unique diagnoses were missed. Most missed diagnoses were common conditions in primary care, with pneumonia (6.7%), decompensated congestive heart failure (5.7%), acute renal failure (5.3%), cancer (primary) (5.3%), and urinary tract infection or pyelonephritis (4.8%) being most common. Process breakdowns most frequently involved the patient-practitioner clinical encounter (78.9%) but were also related to referrals (19.5%), patient-related factors (16.3%), follow-up and tracking of diagnostic information (14.7%), and performance and interpretation of diagnostic tests (13.7%). A total of 43.7% of cases involved more than one of these processes. Patient-practitioner encounter breakdowns were primarily related to problems with history-taking (56.3%), examination (47.4%), and/or ordering diagnostic tests for further workup (57.4%). Most errors were associated with potential for moderate to severe harm. CONCLUSIONS AND RELEVANCE Diagnostic errors identified in our study involved a large variety of common diseases and had significant potential for harm. Most errors were related to process breakdowns in the patient-practitioner clinical encounter. Preventive interventions should target common contributory factors across diagnoses, especially those that involve data gathering and synthesis in the patient-practitioner encounter.JAMA internal medicine. 02/2013; -
Article: Impact of resident duty hour limits on safety in the intensive care unit: A national survey of pediatric and neonatal intensivists*
[show abstract] [hide abstract]
ABSTRACT: OBJECTIVE:: Resident duty-hour regulations potentially shift the workload from resident to attending physicians. We sought to understand how current or future regulatory changes might impact safety in academic pediatric and neonatal intensive care units. DESIGN:: Web-based survey. SETTING:: U.S. academic pediatric and neonatal intensive care units. SUBJECTS:: Attending pediatric and neonatal intensivists. INTERVENTIONS:: We evaluated perceptions on four intensive care unit safety-related risk measures potentially affected by current duty-hour regulations: 1) attending physician and resident fatigue; 2) attending physician workload; 3) errors (self-reported rates by attending physicians or perceived resident error rates); and 4) safety culture. We also evaluated perceptions of how these risks would change with further duty-hour restrictions. MEASUREMENTS AND MAIN RESULTS:: We administered our survey between February and April 2010 to 688 eligible physicians, of whom 360 (52.3%) responded. Most believed that resident error rates were unchanged or worse (91.9%) and safety culture was unchanged or worse (84.4%) with current duty-hour regulations. Of respondents, 61.9% believed their own work-hours providing direct patient care increased and 55.8% believed they were more fatigued while providing direct patient care. Most (85.3%) perceived no increase in their own error rates currently, but in the scenario of further reduction in resident duty-hours, over half (53.3%) believed that safety culture would worsen and a significant proportion (40.3%) believed that their own error rates would increase. CONCLUSIONS:: Pediatric intensivists do not perceive improved patient safety from current resident duty-hour restrictions. Policies to further restrict resident duty-hours should consider unintended consequences of worsening certain aspects of intensive care unit safety.Pediatric Critical Care Medicine 05/2012; 13(5):578-582. · 3.13 Impact Factor -
Article: Error disclosure: a new domain for safety culture assessment.
[show abstract] [hide abstract]
ABSTRACT: To (1) develop and test survey items that measure error disclosure culture, (2) examine relationships among error disclosure culture, teamwork culture and safety culture and (3) establish predictive validity for survey items measuring error disclosure culture. All clinical faculty from six health institutions (four medical schools, one cancer centre and one health science centre) in The University of Texas System were invited to anonymously complete an electronic survey containing questions about safety culture and error disclosure. The authors found two factors to measure error disclosure culture: one factor is focused on the general culture of error disclosure and the second factor is focused on trust. Both error disclosure culture factors were unique from safety culture and teamwork culture (correlations were less than r=0.85). Also, error disclosure general culture and error disclosure trust culture predicted intent to disclose a hypothetical error to a patient (r=0.25, p<0.001 and r=0.16, p<0.001, respectively) while teamwork and safety culture did not predict such an intent (r=0.09, p=NS and r=0.12, p=NS). Those who received prior error disclosure training reported significantly higher levels of error disclosure general culture (t=3.7, p<0.05) and error disclosure trust culture (t=2.9, p<0.05). The authors created and validated a new measure of error disclosure culture that predicts intent to disclose an error better than other measures of healthcare culture. This measure fills an existing gap in organisational assessments by assessing transparent communication after medical error, an important aspect of culture.BMJ quality & safety 05/2012; 21(7):594-9. -
Article: Explanations for Unsuccessful Weight Loss Among Bariatric Surgery Candidates
[show abstract] [hide abstract]
ABSTRACT: BackgroundOur objective was to analyze subjective explanations for unsuccessful weight loss among bariatric surgery candidates. MethodsThis was a retrospective analysis of 909 bariatric surgery candidates (78.2% female, average body mass index [BMI] 47.3) at a university center from 2001 to April 2007 who answered an open-ended question about why they were unable to lose weight. We generated a coding scheme for answers to the question and established inter-rater reliability of the coding process. Associations with demographic parameters and initial BMI were tested. ResultsThe most common categories of answers were nonspecific explanations related to diet (25.3%), physical activity (21.0%), or motivation (19.7%), followed by diet-related motivation (12.7%) and medical conditions or medications affecting physical activity (12.7%). Categories related to time, financial cost, social support, physical environment, and knowledge occurred in less than 4% each. Men were more likely than women to cite a medical condition or medication affecting physical activity (19.2% vs 10.8%, P = 0.002, odds ratio [OR] = 1.96, 95% confidence interval [CI] = 1.28–2.99) but less likely to cite diet-related motivation (7.1% vs 14.2%, P = 0.008, OR = 0.46, 95% CI = 0.26–0.82). ConclusionsOur findings suggest that addressing diet, physical activity, and motivation in a comprehensive approach would meet the stated needs of obese patients. Raising patient awareness of under-recognized barriers to weight loss, such as the physical environment and lack of social support, should also be considered. Lastly, anticipating gender-specific attributions may facilitate tailoring of interventions.Obesity Surgery 04/2012; 19(10):1377-1383. · 3.29 Impact Factor -
Article: Comparing two safety culture surveys: safety attitudes questionnaire and hospital survey on patient safety.
[show abstract] [hide abstract]
ABSTRACT: To examine the reliability and predictive validity of two patient safety culture surveys-Safety Attitudes Questionnaire (SAQ) and Hospital Survey on Patient Safety Culture (HSOPS)-when administered to the same participants. Also to determine the ability to convert HSOPS scores to SAQ scores. Employees working in intensive care units in 12 hospitals within a large hospital system in the southern United States were invited to anonymously complete both safety culture surveys electronically. All safety culture dimensions from both surveys (with the exception of HSOPS's Staffing) had adequate levels of reliability. Three of HSOPS's outcomes-frequency of event reporting, overall perceptions of patient safety, and overall patient safety grade-were significantly correlated with SAQ and HSOPS dimensions of culture at the individual level, with correlations ranging from r=0.41 to 0.65 for the SAQ dimensions and from r=0.22 to 0.72 for the HSOPS dimensions. Neither the SAQ dimensions nor the HSOPS dimensions predicted the fourth HSOPS outcome-number of events reported within the last 12 months. Regression analyses indicated that HSOPS safety culture dimensions were the best predictors of frequency of event reporting and overall perceptions of patient safety while SAQ and HSOPS dimensions both predicted patient safety grade. Unit-level analyses were not conducted because indices did not indicate that aggregation was appropriate. Scores were converted between the surveys, although much variance remained unexplained. Given that the SAQ and HSOPS had similar reliability and predictive validity, investigators and quality and safety leaders should consider survey length, content, sensitivity to change and the ability to benchmark when selecting a patient safety culture survey.BMJ quality & safety 04/2012; 21(6):490-8. -
Article: Acceptability of narratives to promote colorectal cancer screening in an online community.
[show abstract] [hide abstract]
ABSTRACT: To assess the acceptability of narratives to promote colorectal cancer (CRC) screening among members of an online weight loss community. Members of online weight loss community completed an Internet survey in 2010. Multiple logistic regression models examined demographic and attitudinal correlates of interest in sharing and receiving CRC screening narratives. Participants (n=2386) were 92% female with mean (SD) age 58 (6) years; 68% were up-to-date with CRC screening. Among those who were up-to-date, 39% were interested in sharing their narratives with other members. African-Americans were more likely than other racial groups to be interested in sharing narratives (adjusted OR 2.02, 95% CI 1.14-3.57). Older, married members and those with greater CRC screening worries were less likely to be interested in sharing narratives. Among those not up-to-date, 63% were interested in receiving narratives from online community members, and those with higher perceived salience of CRC screening were more likely to be interested in receiving narratives (adjusted OR 1.86, 95% CI 1.31-2.65). Members of this online weight loss community expressed interest in sharing and receiving narratives for CRC screening promotion. Attitudes and demographic characteristics may predict successful recruitment of those who would share and receive narratives.Preventive Medicine 03/2012; 54(6):405-7. · 3.22 Impact Factor -
Article: The Safety Attitudes Questionnaire as a tool for benchmarking safety culture in the NICU.
[show abstract] [hide abstract]
ABSTRACT: Neonatal intensive care unit (NICU) safety culture, as measured by the Safety Attitudes Questionnaire (SAQ), varies widely. Associations with clinical outcomes in the adult intensive care unit setting make the SAQ an attractive tool for comparing clinical performance between hospitals. Little information is available on the use of the SAQ for this purpose in the NICU setting. To determine whether the dimensions of safety culture measured by the SAQ give consistent results when used as a NICU performance measure. Cross-sectional survey of caregivers in 12 NICUs, using the six scales of the SAQ: teamwork climate, safety climate, job satisfaction, stress recognition, perceptions of management and working conditions. NICUs were ranked by quantifying their contribution to overall risk-adjusted variation across the scales. Spearman rank correlation coefficients were used to test for consistency in scale performance. The authors then examined whether performance in the top four NICUs in one scale predicted top four performance in others. There were 547 respondents in 12 NICUs. Of 15 NICU-level correlations in performance ranking, two were >0.7, seven were between 0.4 and 0.69, and the six remaining were <0.4. The authors found a trend towards significance in comparing the distribution of performance in the top four NICUs across domains with a binomial distribution p=0.051, indicating generally consistent performance across dimensions of safety culture. A culture of safety permeates many aspects of patient care and organisational functioning. The SAQ may be a useful tool for comparative performance assessments among NICUs.Archives of Disease in Childhood - Fetal and Neonatal Edition 03/2012; 97(2):F127-32. · 3.05 Impact Factor -
Article: Electronic health record-based surveillance of diagnostic errors in primary care.
[show abstract] [hide abstract]
ABSTRACT: Diagnostic errors in primary care are harmful but difficult to detect. The authors tested an electronic health record (EHR)-based method to detect diagnostic errors in routine primary care practice. The authors conducted a retrospective study of primary care visit records 'triggered' through electronic queries for possible evidence of diagnostic errors: Trigger 1: A primary care index visit followed by unplanned hospitalisation within 14 days and Trigger 2: A primary care index visit followed by ≥1 unscheduled visit(s) within 14 days. Control visits met neither criterion. Electronic trigger queries were applied to EHR repositories at two large healthcare systems between 1 October 2006 and 30 September 2007. Blinded physician-reviewers independently determined presence or absence of diagnostic errors in selected triggered and control visits. An error was defined as a missed opportunity to make or pursue the correct diagnosis when adequate data were available at the index visit. Disagreements were resolved by an independent third reviewer. Queries were applied to 212 165 visits. On record review, the authors found diagnostic errors in 141 of 674 Trigger 1-positive records (positive predictive value (PPV)=20.9%, 95% CI 17.9% to 24.0%) and 36 of 669 Trigger 2-positive records (PPV=5.4%, 95% CI 3.7% to 7.1%). The control PPV of 2.1% (95% CI 0.1% to 3.3%) was significantly lower than that of both triggers (p≤0.002). Inter-reviewer reliability was modest, though higher than in comparable previous studies (к=0.37 (95% CI 0.31 to 0.44)). While physician agreement on diagnostic error remains low, an EHR-facilitated surveillance methodology could be useful for gaining insight into the origin of these errors.BMJ quality & safety 02/2012; 21(2):93-100. -
Article: Structural social support predicts functional social support in an online weight loss programme.
[show abstract] [hide abstract]
ABSTRACT: Background Online weight loss programmes allow members to use social media tools to give and receive social support for weight loss. However, little is known about the relationship between the use of social media tools and the perception of specific types of support. Objective To test the hypothesis that the frequency of using social media tools (structural support) is directly related to perceptions of Encouragement, Information and Shared Experiences support (functional support). Design Online survey. Participants Members of an online weight loss programme. Methods The outcome was the perception of Encouragement (motivation, congratulations), Information (advice, tips) and Shared Experiences (belonging to a group) social support. The predictor was a social media scale based on the frequency of using forums and blogs within the online weight loss programme (alpha = 0.91). The relationship between predictor and outcomes was evaluated with structural equation modelling (SEM) and logistic regression, adjusted for sociodemographic characteristics, BMI and duration of website membership. Results The 187 participants were mostly female (95%) and white (91%), with mean (SD) age 37 (12) years and mean (SD) BMI 31 (8). SEM produced a model in which social media use predicted Encouragement support, but not Information or Shared Experiences support. Participants who used the social media tools at least weekly were almost five times as likely to experience Encouragement support compared to those who used the features less frequently [adjusted OR 4.8 (95% CI 1.8-12.8)]. Conclusions Using the social media tools of an online weight loss programme at least once per week is strongly associated with receiving Encouragement for weight loss behaviours.Health expectations: an international journal of public participation in health care and health policy 01/2012; · 1.80 Impact Factor -
Article: Rethinking resident supervision to improve safety: from hierarchical to interprofessional models.
[show abstract] [hide abstract]
ABSTRACT: Inadequate supervision is a significant contributing factor to medical errors involving trainees, but supervision in high-risk settings such as the intensive care unit (ICU) is not well studied. We explored how residents in the ICU experienced supervision related to medication safety, not only from supervising physicians but also from other professionals. DESIGN, SETTING, MEASUREMENTS: Using qualitative methods, we examined in-depth interviews with 17 residents working in ICUs of three tertiary-care hospitals. We analyzed residents' perspectives on receiving and initiating supervision from physicians within the traditional medical hierarchy, and from other professionals, including nurses, staff pharmacists, and clinical pharmacists ("interprofessional supervision"). While initiating their own supervision within the traditional hierarchy, residents believed in seeking assistance from fellows and attendings, and articulated rules of thumb for doing so; however, they also experienced difficulties. Some residents were concerned that their questions would reflect poorly on them; others were embarrassed by their mistaken decisions. Conversely, residents described receiving interprofessional supervision from nurses and pharmacists, who proactively monitored, intervened in, and guided residents' decisions. Residents relied on nurses and pharmacists for nonjudgmental answers to their queries, especially after-hours. To enhance both types of supervision, residents emphasized the importance of improving interpersonal communication skills. Residents depended on interprofessional supervision when making decisions regarding medications in the ICU. Improving interprofessional supervision, which thus far has been underrecognized and underemphasized in graduate medical education, can potentially improve medication safety in high-risk settings.Journal of Hospital Medicine 10/2011; 6(8):445-52. · 1.40 Impact Factor -
Article: Neonatal intensive care unit safety culture varies widely.
[show abstract] [hide abstract]
ABSTRACT: Variation in healthcare delivery and outcomes in neonatal intensive care units (NICUs) may be partly explained by differences in safety culture. To describe NICU care giver assessments of safety culture, explore variability within and between NICUs on safety culture domains, and test for association with care giver characteristics. NICU care givers in 12 hospitals were surveyed using the Safety Attitudes Questionnaire (SAQ), which has six scales: teamwork climate, safety climate, job satisfaction, stress recognition, perception of management and working conditions. Scale means, SDs and percent positives (percent agreement) were calculated for each NICU. There was substantial variation in safety culture domains among NICUs. Composite mean score across the six domains ranged from 56.3 to 77.8 on a 100-point scale and NICUs in the top four NICUs were significantly different from the bottom four (p<0.001). Across the six domains, respondent assessments varied widely, but were least positive on perceptions of management (3%-80% positive; mean 33.3%) and stress recognition (18%-61% positive; mean 41.3%). Comparisons of SAQ scale scores between NICUs and a previously published adult ICU cohort generally revealed higher scores for NICUs. Composite scores for physicians were 8.2 (p=0.04) and 9.5 (p=0.02) points higher than for nurses and ancillary personnel. There is significant variation and scope for improvement in safety culture among these NICUs. The NICU variation was similar to variation in adult ICUs, but NICU scores were generally higher. Future studies should validate whether safety culture measured with the SAQ correlates with clinical and operational outcomes in NICUs.Archives of Disease in Childhood - Fetal and Neonatal Edition 09/2011; 97(2):F120-6. · 3.05 Impact Factor -
Article: Exploring situational awareness in diagnostic errors in primary care.
[show abstract] [hide abstract]
ABSTRACT: Diagnostic errors in primary care are harmful but poorly studied. To facilitate the understanding of diagnostic errors in real-world primary care settings that use electronic health records (EHRs), this study explored the use of the situational awareness (SA) framework from aviation human factors research. A mixed-methods study was conducted involving reviews of EHR data followed by semi-structured interviews of selected providers from two institutions in the USA. The study population included 380 consecutive patients with colorectal and lung cancers diagnosed between February 2008 and January 2009. Using a pre-tested data collection instrument, trained physicians identified diagnostic errors, defined as lack of timely action on one or more established indications for diagnostic work-up for lung and colorectal cancers. Twenty-six providers involved in cases with and without errors were interviewed. Interviews probed for providers' lack of SA and how this may have influenced the diagnostic process. Of 254 cases meeting inclusion criteria, errors were found in 30 of 92 (32.6%) lung cancer cases and 56 of 167 (33.5%) colorectal cancer cases. Analysis of interviews related to error cases revealed evidence of lack of one of four levels of SA applicable to primary care practice: information perception, information comprehension, forecasting future events, and choosing appropriate action based on the first three levels. In cases without error, application of the SA framework provided insight into processes involved in attention management. A framework of SA can help analyse and understand diagnostic errors in primary care settings that use EHRs.BMJ quality & safety 09/2011; 21(1):30-8. -
Article: Improving erythropoietin-stimulating agent administration in a multihospital system through quality improvement initiatives: a pre-post comparison study.
[show abstract] [hide abstract]
ABSTRACT: : Erythropoietin-stimulating agent (ESA) use is associated with serious adverse events in patients with hemoglobin levels of 12 g/dL or higher at the time of administration. Our aim was to determine whether inappropriate ESA use has changed over time since the implementation of new drug warning alerts and local quality improvement initiatives. : We performed a retrospective review of ESA administration practices at Memorial Hermann Healthcare System (Houston, Tex). Our primary outcome measure was the proportion of inpatient encounters (one entire inpatient hospital stay) with 1 or more inappropriate uses of ESA (defined as ESA administration for a patient with hemoglobin ≥12 g/dL). We analyzed the potential influence of local and national interventions on ESA utilization patterns. : Between May 1, 2006, and May 31, 2009, 15,642 inpatients were treated with ESAs in our system. We classified inpatients as before intervention (n = 6350) and after intervention (n = 9292) based on the date of implementation of a synchronous alert in the electronic medical record. We found a significant decrease in inappropriate ESA administration before to after intervention (9.03%-6.21%; P < 0.001), which can be translated into a 31.25% (05% CI, 21.93%-40.75%) relative risk reduction. Reduced odds ratios for inappropriate ESA use changed little after controlling for relevant demographic variables and clinical characteristics. : Following several quality improvement interventions to improve patient safety related to ESA use, we found a significant reduction in inappropriate ESA administration to inpatients in a large health care system.Journal of Patient Safety 06/2011; 7(3):127-32. -
Article: Costs and cost-effectiveness of a telemedicine intensive care unit program in 6 intensive care units in a large health care system.
[show abstract] [hide abstract]
ABSTRACT: The purpose of this study is to estimate the costs and cost-effectiveness of a telemedicine intensive care unit (ICU) (tele-ICU) program. We used an observational study with ICU patients cared for during the pre-tele-ICU period and ICU patients cared for during the post-tele-ICU period in 6 ICUs at 5 hospitals that are part of a large nonprofit health care system in the Gulf Coast region. We obtained data on a sample of 4142 ICU patients: 2034 in the pre-tele-ICU period and 2108 in the post-tele-ICU period. Economic outcomes were hospital costs, ICU costs and floor costs, measured for average daily costs, costs per case, and costs per patient. After the implementation of the tele-ICU, the hospital daily cost increased from $4302 to $5340 (24%); the hospital cost per case, from $21,967 to $31,318 (43%); and the cost per patient, from $20,231 to $25,846 (28%). Although the tele-ICU intervention was not cost-effective in patients with Simplified Acute Physiology Score II 50 or less, it was cost-effective in the sickest patients with Simplified Acute Physiology Score II more than 50 (17% of patients) because it decreased hospital mortality without increasing costs significantly. Hospital administrators may conclude that a tele-ICU program aimed at the sickest patients is cost-effective.Journal of critical care 03/2011; 26(3):329.e1-6. · 2.13 Impact Factor -
Article: Measuring social support for weight loss in an internet weight loss community.
[show abstract] [hide abstract]
ABSTRACT: Although overweight and obese individuals are turning to Internet communities for social support for weight loss, there is no validated online instrument for measuring the subjective social support experiences of participants in these communities. The authors' objective was to determine whether an online version of a validated paper questionnaire, the Weight Management Support Inventory, is appropriate for measuring social support among members of Internet weight loss communities. The authors administered the paper and online versions of the questionnaire in random, counterbalanced fashion to 199 members of a large Internet weight loss community. Scores for the paper and online versions were comparable in between-subjects and within-subjects comparisons. Convergent validity is suggested by the finding that participants who posted messages on Internet forums several times per day reported more social support than those who posted less frequently. However, the instrumental (tangible) support items did not load significantly on the instrumental support factor, suggesting that instrumental support is not relevant to the social support exchanged among participants in these communities. The authors conclude that the online, modified Weight Management Support Inventory, without items for instrumental support, is an appropriate instrument for measuring social support for weight loss among members of Internet weight loss communities.Journal of Health Communication 02/2011; 16(2):198-211. · 1.61 Impact Factor -
Article: Compliance with guidelines to prevent surgical site infections: As simple as 1-2-3?
[show abstract] [hide abstract]
ABSTRACT: the purpose of this study was to assess predictive factors and compliance with surgical site infection (SSI) prevention guidelines at 2 county hospitals. chart review and analysis of laparotomy patients undergoing colorectal, hysterectomy, or abdominal vascular procedures over two 6-month periods 1 year apart and evaluation of safety climate using the Safety Attitudes Questionnaire (SAQ). overall compliance with all antibiotic prophylaxis guidelines was 62% (n = 442). Gynecologic surgery was an independent predictor of compliance with antibiotic prophylaxis guidelines in elective cases, and nonemergency status was an independent predictor when all cases were considered. Postoperative normothermia was predicted by hospital, procedure length, initial intraoperative temperature, and service. The SAQ had a 91% response rate. Contrary to expected, safety domain scores and agreement with statements on collaboration and teamwork were not predictive of compliance. interventions to improve poor compliance with infection prevention guidelines must be multifaceted, hospital- and service-specific, and resilient during emergencies. Good safety and teamwork climate are not sufficient.American journal of surgery 01/2011; 201(1):76-83. · 2.36 Impact Factor -

Article: A tale of 2 hospitals: a staggered cohort study of targeted interventions to improve compliance with antibiotic prophylaxis guidelines.
[show abstract] [hide abstract]
ABSTRACT: The purpose of this prospective study was to determine the effectiveness of targeted interventions to improve compliance with antibiotic prophylaxis guidelines (timing, spectrum, and discontinuation) at 2 university-affiliated hospitals. Based on barriers identified previously, hospital-specific interventions were developed such as educational conferences, standardized forms, an extended time-out, and feedback. Guideline compliance and surgical site infection (SSI) data were recorded on all patients who underwent elective laparotomies for colorectal procedures, vascular operations, and hysterectomies during four 6-month study periods. Prestudy data from July to December 2006 served as a baseline. One year later, a prospective cohort study was performed. The interventions were introduced to the 2 hospitals in a staggered fashion with 2-month implementation periods before reassessing compliance during the 6-month study periods. General linear modeling was performed (P < .05 significant). Compliance with all 3 guidelines combined improved during the year preceding the study, after attention only, at both hospitals. Hospital-specific differences were found in the effectiveness of the intervention package on individual guidelines. Hospital 2 but not 1 improved in timing after the interventions; both hospitals improved in spectrum, and neither hospital improved in discontinuation. Overall compliance with all 3 antibiotic prophylactic measures was greater at hospital 1, but hospital 2 had lower SSI rates. Simply increasing attention to a quality problem can result in a significant and sustained improvement. Quality improvement interventions should be evaluated rigorously for effectiveness given hospital-specific differences in effectiveness and for correlation of guideline compliance with outcome.Surgery 08/2010; 148(2):255-62. · 3.10 Impact Factor -
Article: Errors of diagnosis in pediatric practice: a multisite survey.
[show abstract] [hide abstract]
ABSTRACT: We surveyed pediatricians to elicit their perceptions regarding frequency, contributing factors, and potential system- and provider-based solutions to address diagnostic errors. Academic, community, and trainee pediatricians (N = 1362) at 3 tertiary care institutions and 109 affiliated clinics were invited to complete the survey anonymously through an Internet survey administration service between November 2008 and May 2009. The overall response rate was 53% (N = 726). More than one-half (54%) of respondents reported that they made a diagnostic error at least once or twice per month; this frequency was markedly higher (77%) among trainees. Almost one-half (45%) of respondents reported diagnostic errors that harmed patients at least once or twice per year. Failure to gather information through history, physical examination, or chart review was the most-commonly reported process breakdown, whereas inadequate care coordination and teamwork was the most-commonly reported system factor. Viral illnesses being diagnosed as bacterial illnesses was the most-commonly reported diagnostic error, followed by misdiagnosis of medication side effects, psychiatric disorders, and appendicitis. Physicians ranked access to electronic health records and close follow-up of patients as strategies most likely to be effective in preventing diagnostic errors. Pediatricians reported making diagnostic errors relatively frequently, and patient harm from these errors was not uncommon.PEDIATRICS 07/2010; 126(1):70-9. · 4.47 Impact Factor -
Article: Job satisfaction ratings: measurement equivalence across nurses and physicians.
[show abstract] [hide abstract]
ABSTRACT: The measurement equivalence of job satisfaction ratings from physicians and nurses working in intensive care units was tested in the present study. Seventy-two nurses and 72 physicians completed the Safety Attitudes Questionnaire, which contains five items about job satisfaction. Measurement equivalence across nurses and physicians of the job satisfaction ratings was examined via multiple-group confirmatory factor analysis. The results indicated that physicians and nurses use the same metric when providing ratings for this job satisfaction measure. The primary implication from the present study is that nurses and physicians conceptualize job satisfaction in a similar manner. This implication needs to be extended to other survey measures of interest to health services researchers. Future areas of research are discussed.Western Journal of Nursing Research 06/2010; 32(4):530-9. · 1.19 Impact Factor
