Resuscitation Practices Associated With Survival After In-Hospital Cardiac Arrest: A Nationwide Survey.

ABSTRACT: IMPORTANCE:Although survival of patients with in-hospital cardiac arrest varies markedly among hospitals, specific resuscitation practices that distinguish sites with higher cardiac arrest survival rates remain unknown. OBJECTIVE:To identify resuscitation practices associated with higher rates of in-hospital cardiac arrest survival. DESIGN, SETTING, AND PARTICIPANTS:Nationwide survey of resuscitation practices at hospitals participating in the Get With the Guidelines-Resuscitation registry and with 20 or more adult in-hospital cardiac arrest cases from January 1, 2012, through December 31, 2013. Data analysis was performed from June 10 to December 22, 2015. MAIN OUTCOMES AND MEASURES:Risk-standardized survival rates for cardiac arrest were calculated at each hospital and were then used to categorize hospitals into quintiles of performance. The association between resuscitation practices and quintiles of survival was evaluated using hierarchical proportional odds logistic regression models. RESULTS:Overall, 150 (78.1%) of 192 eligible hospitals completed the study survey, and 131 facilities with 20 or more adult in-hospital cardiac arrest cases comprised the final study cohort. Risk-standardized survival rates after in-hospital cardiac arrest varied substantially (median, 23.7%; range, 9.2%-37.5%). Several resuscitation practices were associated with survival on bivariate analysis, although only 3 were significant after multivariable adjustment: monitoring for interruptions in chest compressions (adjusted odds ratio [OR] for being in a higher survival quintile category, 2.71; 95% CI, 1.24-5.93; P?=?.01), reviewing cardiac arrest cases monthly (adjusted OR for being in a higher survival quintile category, 8.55; 95% CI, 1.79-40.00) or quarterly (OR, 6.85; 95% CI, 1.49-31.30; P?=?.03), and adequate resuscitation training (adjusted OR, 3.23; 95% CI, 1.21-8.33; P?=?.02). CONCLUSIONS AND RELEVANCE:Using survey information from acute care hospitals participating in a national quality improvement registry, we identified 3 resuscitation strategies associated with higher hospital rates of survival for patients with in-hospital cardiac arrest. These strategies can form the foundation for best practices for resuscitation care at hospitals given the high incidence and variation in survival for in-hospital cardiac arrest.

Project description:Background and objectivesPatients on maintenance dialysis with in-hospital cardiac arrest have been reported to have worse outcomes relative to those not on dialysis; however, it is unknown if poor outcomes are related to the quality of resuscitation. Using the Get With The Guidelines-Resuscitation (GWTG-R) registry, we examined processes of care and outcomes of in-hospital cardiac arrest for patients on maintenance dialysis compared with nondialysis patients.Design, setting, participants, & measurementsWe used GWTG-R data linked to Centers for Medicare and Medicaid data to identify patients with ESKD receiving maintenance dialysis from 2000 to 2012. We then case-matched adult patients on maintenance dialysis to nondialysis patients in a 1:3 ratio on the basis of age, sex, race, hospital, and year of arrest. Logistic regression models with generalized estimating equations were used to assess the association of in-hospital cardiac arrest and outcomes by dialysis status.ResultsAfter matching, there were a total of 31,144 GWTG-R patients from 372 sites, of which 8498 (27%) were on maintenance dialysis. Patients on maintenance dialysis were less likely to have a shockable initial rhythm (20% versus 21%) and less likely to be within the intensive care unit at the time of arrest (46% versus 47%) compared with nondialysis patients; they also had lower composite scores for resuscitation quality (89% versus 90%) and were less likely to have defibrillation within 2 minutes (54% versus 58%). After adjustment, patients on maintenance dialysis had similar adjusted odds of survival to discharge (odds ratio [OR], 1.05; 95% confidence interval [95% CI], 0.97 to 1.13), better acute survival (OR, 1.33; 95% CI, 1.26 to 1.40), and were more likely to have favorable neurologic status (OR, 1.12; 95% CI, 1.04 to 1.22) compared with nondialysis patients.ConclusionsAlthough there appears to be opportunities to improve the quality of in-hospital cardiac arrest care for among those on maintenance dialysis, survival to discharge was similar for these patients compared with nondialysis patients.

Project description:BackgroundMaternal in-hospital cardiac arrest is a rare event with the potential for resuscitation treatment delays because of the difficulty accessing hospital obstetrical units and limited simulation training or resuscitation experience of obstetrical staff. However, it is unclear whether survival rates and processes of care differ between women with a maternal in-hospital cardiac arrest and those with a nonmaternal in-hospital cardiac arrest.ObjectiveWe aimed determine whether to there are delays in process measures and differences in survival outcomes between pregnant and nonpregnant women who have in-hospital cardiac arrest.Study designUsing data from 2000 to 2019 in the Get With The Guidelines-Resuscitation registry, we compared resuscitation outcomes between women aged 18 to 50 years with a maternal or nonmaternal in-hospital cardiac arrest. Using a nonparsimonious propensity score, we matched patients with a maternal in-hospital cardiac arrest to as many as 10 women with a nonmaternal in-hospital cardiac arrest. We constructed conditional logistic regression models to compare survival outcomes (survival to discharge, favorable neurologic survival [discharge cerebral performance score of 1], and return of spontaneous circulation) and processes of care (delayed defibrillation [>2 minutes] and administration of epinephrine [>5 minutes]) between women with a maternal in-hospital cardiac arrest vs those with a nonmaternal in-hospital cardiac arrest.ResultsOverall, 421 women with a maternal in-hospital cardiac arrest were matched by propensity score to 2316 women with a nonmaternal in-hospital cardiac arrest. The mean age among propensity score-matched women with a maternal in-hospital cardiac arrest was 31.4 (standard deviation, 6.5) years, where 33.7% were of Black race and 86.9% had an initial nonshockable cardiac arrest rhythm. Unadjusted survival rates were higher in women with a maternal in-hospital cardiac arrest than in women with a nonmaternal in-hospital cardiac arrest: survival to discharge of 45.1% vs 26.5%, survival with cerebral performance category 1 status of 36.1% vs 17.7%, and return of spontaneous circulation of 75.8% vs 70.6%. After adjustment, there was no difference in the likelihood of survival to discharge (odds ratio, 1.19; 95% confidence interval, 0.82-1.73) or return of spontaneous circulation (odds ratio, 0.94; 95% confidence interval, 0.65-1.35) between women with a maternal in-hospital cardiac arrest and those with a nonmaternal in-hospital cardiac arrest. However, women with a maternal in-hospital cardiac arrest were more likely to have favorable neurologic survival (odds ratio, 1.57; 95% confidence interval, 1.06-2.33). Compared with women with a nonmaternal in-hospital cardiac arrest, women with a maternal in-hospital cardiac arrest had similar rates of delayed defibrillation (42.5% vs 34.4%; odds ratio, 1.14 [95% confidence interval, 0.41-3.18]; P=.31) and delayed administration of epinephrine (13.8% vs 10.6%; odds ratio, 0.96 [95% confidence interval, 0.50-1.86]; P=.09).ConclusionAlthough concerns have been raised about resuscitation outcomes in women with a maternal in-hospital cardiac arrest, the rates of survival and resuscitation processes of care were not worse in women with a maternal in-hospital cardiac arrest.

Project description:Background Identifying actionable resuscitation practices that vary across hospitals could improve adherence to process measures or outcomes after in-hospital cardiac arrest (IHCA). We sought to examine whether hospital debriefing frequency after IHCA varies across hospitals and whether hospitals which routinely perform debriefing have higher rates of process-of-care compliance or survival. Methods We conducted a nationwide survey of hospital resuscitation practices in April of 2018, which were then linked to data from the Get With The Guidelines-Resuscitation national registry for IHCA. Hospitals were categorized according to their reported frequency of debriefing immediately after IHCA; rarely (0%-20% of all IHCA cases), occasionally (21%-80%), and frequently (81%-100%). Hospital-level rates of timely defibrillation (≤2 minutes), epinephrine administration (≤5 minutes), survival to discharge, return of spontaneous circulation, and neurologically intact survival were comparted for patients with IHCA from 2015 to 2017. Results Overall, there were 193 hospitals comprising 44 477 IHCA events. Mean patient age was 65±16, 41% were females, and 68% were of White race. Across hospitals, 84 (43.5%) rarely performed debriefings immediately after an IHCA, 82 (42.5%) performed debriefing sessions occasionally, and 27 (14.0%) performed debriefing frequently. There was no association between higher reported debriefing frequency and hospital rates of timely defibrillation and epinephrine administration. Mean hospital rates of risk-standardized survival to discharge were similar across debriefing frequency groups (rarely 25.6%; occasionally 26.0%; frequently 25.2%, P=0.72), as were hospital rates of risk-adjusted return of spontaneous circulation (rarely 72.2%; occasionally 73.0%; frequently 70.0%, P=0.06) and neurologically intact survival (rarely 21.9%, occasionally 22.2%, frequently 21.1%, P=0.75). Conclusions In a large contemporary nationwide quality improvement registry, hospitals varied widely in how often they conducted debriefings immediately after IHCA. However, hospital debriefing frequency was not associated with better adherence to timely delivery of epinephrine or defibrillation or higher rates of IHCA survival.

Project description:BACKGROUND:The prognosis in refractory out-of-hospital cardiac arrest (OHCA) with ongoing cardiopulmonary resuscitation (CPR) at hospital arrival is often considered dismal. The use of extracorporeal cardiopulmonary resuscitation (eCPR) for perfusion enhancement during resuscitation has shown variable results. We aimed to investigate outcome in refractory OHCA patients managed conservatively without use of eCPR. METHODS:We included consecutive OHCA patients with refractory arrest or prehospital return of spontaneous circulation (ROSC) in the Copenhagen area in 2002-2011. RESULTS:A total of 3992 OHCA patients with resuscitation attempts were included; in 2599, treatment was terminated prehospital, and 1393 (35%) were brought to the hospital either with ROSC (n?=?1285, 92%) or with refractory OHCA (n?=?108, 8%). Of patients brought in with refractory OHCA, 56 (52%) achieved ROSC in the emergency department. There were no differences between patients with refractory OHCA or prehospital ROSC with regard to age, sex, comorbidities, or etiology of OHCA. Time to emergency medical services (EMS) arrival was similar, whereas time to ROSC (when ROSC was achieved) was longer in refractory OHCA patients (EMS, 6 (5-9] vs. 7 [5-10] min, p?=?0.8; ROSC, 15 [9-22] vs. 27 [20-41] min, p?<?0.001). Independent factors associated with transport with refractory OHCA instead of prehospital termination of therapy were OHCA in public (OR, 3.6 [95% CI, 2.2-5.8]; p?<?0.001), witnessed OHCA (OR, 3.7 [2.0-7.1]; p?<?0.001), shockable rhythm (OR, 3.0 [1.9-4.7]; p?<?0.001), younger age (OR, 1.2 [1.1-1.2]; p?<?0.001), and later calendar year (OR, 1.4 [1.2-1.6]; p?<?0.001). Thirty-day survival was 20% in patients with refractory OHCA compared with 42% in patients with prehospital ROSC (p?<?0.001). Four of 28 refractory OHCA patients with duration of resuscitation >?60 min achieved ROSC. No difference in favorable neurological outcome in patients surviving to discharge was found (prehospital ROSC 84% vs. refractory OHCA 86%; p?=?0.7). CONCLUSIONS:Survival after refractory OHCA with ongoing CPR at hospital arrival was significantly lower than among patients with prehospital ROSC. Despite a lower survival, the majority of survivors with both refractory OHCA and prehospital ROSC were discharged with a similar degree of favorable neurological outcome, indicating that continued efforts in spite of refractory OHCA are not in vain and may still lead to favorable outcome even without eCPR.

Project description:BackgroundDuring 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.MethodsBetween 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.Findings31,198 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).InterpretationDuration 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.FundingAmerican Heart Association, Robert Wood Johnson Foundation Clinical Scholars Program, and the National Institutes of Health.

Project description:Background Hospitals participating in the national Get With The Guidelines-Resuscitation registry receive an award for high rates of adherence to quality metrics for in-hospital cardiac arrest. We sought to evaluate whether awards based on these quality metrics can be considered a proxy for performance on cardiac arrest survival. Methods and Results Among 195 hospitals with continuous participation in Get With The Guidelines-Resuscitation between 2012 and 2015, we identified 78 that received an award (Gold or Silver) for ≥85% compliance for all 4 metrics for in-hospital cardiac arrest-time to chest compressions, ≤1 minute; time to defibrillation, ≤2 minutes; device confirmation of endotracheal tube placement; and a monitored/witnessed arrest-for at least 12 consecutive months during 2014 to 2015. Award hospitals had higher cardiac arrest volumes than nonaward hospitals but otherwise had similar site characteristics. During 2014 to 2015, award hospitals had higher rates of return of spontaneous circulation for in-hospital cardiac arrest than nonaward hospitals (median [interquartile range], 71% [64%-77%] versus 66% [59%-74%]; Spearman ρ, 0.19; P=0.009). However, rates of risk-standardized survival to discharge at award hospitals (median, 25% [interquartile range, 22%-30%]) were similar to nonaward hospitals (median, 24% [interquartile range, 12%-27%]; Spearman ρ, 0.13; P=0.06). Among hospitals in the best tertile for survival to discharge in 2014 to 2015, 55.4% (36/65) did not receive an award, with poor discrimination of high-performing hospitals by award status (C statistic, 0.53). Similarly, there was only a weak association between hospitals' award status in 2014 to 2015 and their rates of survival to discharge in the preceding 2-year period (Spearman ρ, 0.16; P=0.03). Conclusions The current recognition mechanism within a national registry for in-hospital cardiac arrest captures hospital performance on return of spontaneous circulation but is not well correlated with survival to discharge. This suggests that current awards for resuscitation quality may not adequately capture hospital performance on overall survival-the outcome of greatest interest to patients.

Project description:BackgroundTo enable older people to make decisions about the appropriateness of cardiopulmonary resuscitation (CPR), information is needed about the predictive value of pre-arrest factors such as comorbidity, functional and cognitive status on survival and quality of life of survivors. We systematically reviewed the literature to identify pre-arrest predictors for survival, quality of life and functional outcomes after out-of-hospital (OHC) CPR in the elderly.MethodsWe searched MEDLINE (through May 2011) and included studies that described adults aged 70 years and over needing CPR after OHC cardiac arrest. Prognostic factors associated with survival to discharge and quality of life of survivors were extracted. Two authors independently appraised the quality of each of the included studies. When possible a meta-analysis of odd's ratios was performed.ResultsTwenty-three studies were included (n = 44,582). There was substantial clinical and statistical heterogeneity and reporting was often inadequate. The pooled survival to discharge in patients >70 years was 4.1% (95% CI 3.0-5.6%). Several studies showed that increasing age was significantly associated with worse survival, but the predictive value of comorbidity was investigated in only one study. In another study, nursing home residency was independently associated with decreased chances of survival. Only a few small studies showed that age is negatively associated with a good quality of life of survivors. We were unable to perform a meta-analysis of possible predictors due to a wide variety in reporting and statistical methods.ConclusionsAlthough older patients have a lower chance of survival after CPR in univariate analysis (i.e. 4.1%), older age alone does not seem to be a good criterion for denying patients CPR. Evidence for the predictive value of comorbidities and for the predictive value of age on quality of life of survivors is scarce. Future studies should use uniform methods for reporting data and pre-arrest factors to increase the available evidence about pre arrest factors on the chance of survival. Furthermore, patient-specific outcomes such as quality of life and post-arrest cognitive function should be investigated too.
