ImportanceAlthough 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.ObjectiveTo identify resuscitation practices associated with higher rates of in-hospital cardiac arrest survival.Design, Setting, And ParticipantsNationwide 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 MeasuresRisk-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.ResultsOverall, 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 RelevanceUsing 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.
