Epidemiology of Critical Care Syndromes, Organ Failures, and Life-Support Interventions in a Suburban US Community
ABSTRACT ICU services represent a significant and increasing proportion of medical care. Population-based epidemiologic studies are essential to inform physicians and policymakers about current and future ICU demands. We aimed to determine the incidence of critical care syndromes, organ failures, and life-support interventions in a defined US suburban community with unrestricted access to critical care services.
This population-based observational cohort from January 1 to December 31, 2006, in Olmsted County, Minnesota, included all consecutive critically ill adult residents admitted to the ICU. Main outcomes were incidence of critical care syndromes, life-support interventions, and organ failures as defined by standard criteria. Incidences are reported per 100,000 population (95% CIs) and were age adjusted to the 2006 US population.
A total of 1,707 ICU admissions were identified from 1,461 patients. Incidences of critical care syndromes were respiratory failure, 430 (390-470); acute kidney injury, 290 (257-323); severe sepsis, 286 (253-319); all-cause shock, 194 (167-221); acute lung injury, 86 (68-105); all-cause coma, 43 (30-55); and overt disseminated intravascular coagulation, 18 (10-26). Incidence of mechanical ventilation was invasive, 310 (276-344); noninvasive, 180 (154-206); vasopressors and inotropes, 183(155-208). Renal replacement therapy incidence was 96 (77-116). Of the cohort, 1,330 patients (91%) survived to hospital discharge. Short- and long-term survival decreased by the number of failing organs.
In a suburban US community with high access to critical care services, cumulative incidences of critical care syndromes and life-support interventions were higher than previously reported. The results of this study have important implications for future planning of critical care delivery.

ABSTRACT: Background Noninvasive mechanical ventilation (NIV) is a front-line therapy for the management of acute respiratory failure (ARF) in the intensive care units. However, the data on factors and outcomes associated with the use of NIV in ARF patients is lacking. Therefore, we aimed to determine the utilization of NIV for ARF in a population-based study. Methods We conducted a populated-based retrospective cohort study, where in all consecutively admitted adults (≥18 years) with ARF from Olmsted County, Rochester, MN, at the Mayo Clinic medical and surgical ICUs, during 2006 were included. Patients without research authorization or on chronic NIV use for sleep apnea were excluded. Results Out of 1461 Olmsted County adult residents admitted to the ICUs in 2006, 364 patients developed ARF, of which 146 patients were initiated on NIV. The median age in years was 75 (interquartile range, 60–84), 48% females and 88.7% Caucasians. Eighteen patients (12%) were on Continuous Positive Airway Pressure (CPAP) mode and 128 (88%) were on noninvasive intermittent positive-pressure ventilation (NIPPV) mode. Forty-six (10%) ARF patients were put on NIV for palliative strategy to alleviate dyspnea. Seventy-six ARF patients without treatment limitation were given a trial of NIV and 49 patients succeeded, while 27 had to be intubated. Mortality was similar between the patients initially supported with NIV versus invasive mechanical ventilation (33% vs 22%, P=0.289). In the multivariate analysis, the development of acute respiratory distress syndrome (ARDS) and higher APACHE III scores were associated with the failure of initial NIV treatment. Conclusions Our results have important implications for a future planning of NIV in a suburban US community with high access to critical care services. The higher APACHE III scores and the development of ARDS are associated with the failure of initial NIV treatment.BMC Emergency Medicine 04/2013; 13(1):6. DOI:10.1186/1471-227X-13-6

ABSTRACT: The aim of this study is to investigate the recent trend over time of outcomes of patients with disseminated intravascular coagulation (DIC) based on the Japanese administrative database. A total of 34,711 patients with DIC had been referred to 1,092 hospitals from 2010 to 2012 in Japan. We collected patients' data from the administrative database to compare in-hospital mortality within 14 and 28 days between periods. The study periods were categorized into three groups: 2010 (n = 8,382), 2011 (n = 13,372), and 2012 (n = 12,957). These analyses were performed according to the underlying diseases associated with DIC. The in-hospital mortality within 14 or 28 days of DIC patients with infectious diseases decreased between 2010 and 2012 (within 14 days: 20.4 vs. 18.1 vs. 17.9 %, P = 0.009; within 28 days: 31.1 vs. 28.7 vs. 27.7 %, P = 0.003; respectively). Multiple logistic regressions also showed that the period was associated with in-hospital mortality of DIC patients with infectious diseases. The odds ratios of 2011 and 2012 for in-hospital mortality within 14 days were 0.86 [95 % confidence intervals (CI) 0.77-0.97] and 0.84 (95 % CI 0.75-0.94) whereas those for in-hospital mortality within 28 days were 0.89 (95 % CI 0.81-0.98) and 0.83 (95 % CI 0.76-0.92), respectively. However, there were no significant differences in mortality of patients with DIC associated with other underlying diseases between 2010 and 2012. This study demonstrated that in-hospital mortality of DIC patients with infectious diseases gradually improved between 2010 and 2012 in Japan.Journal of Thrombosis and Thrombolysis 05/2014; 38(3).

ABSTRACT: The purpose of the study is to evaluate the impact of primary service involvement on rapid response team (RRT) evaluations. The study is a combination of retrospective chart review and prospective survey-based evaluation. Data included when and where the activations occurred and the patient's code status, primary service, and ultimate disposition. These data were correlated with survey data from each event. A prospective survey evaluated the primary team's involvement in decision making and the overall subjective quality of the interaction with primary service through a visual analog scale. We analyzed 4408 RRTs retrospectively and an additional 135 prospectively. The primary team's involvement by telephone or in person was associated with significantly more transfers to higher care levels in retrospective (P < .01) and prospective data sets. Code status was addressed more frequently in primary team involvement, with more frequent changes seen in the retrospective analysis (P = .01). Subjective ratings of communication by the RRT leader were significantly higher when the primary service was involved (P < .001). Active primary team involvement influences RRT activation processes of care. The RRT role should be an adjunct to, but not a substitute for, an engaged and present primary care team.
