• IntroductionThe cumulative burden of chronic health conditions could contribute to out-of-hospital cardiac arrest (OHCA) physiology and response to therapy during attempted resuscitation. Yet little is known about how chronic health conditions influence prognosis. We evaluated the relationship between cumulative comorbidity and outcome following ventricular fibrillation OHCA using 3 different scales.MethodsWe performed a cohort investigation of persons >=18 years who suffered non-traumatic OHCA and presented with ventricular fibrillation between January 1, 2007 and December 31, 2013 in a metropolitan emergency medical service (EMS) system. Chronic conditions were ascertained from EMS reports. The primary relationship between cumulative comorbidity and outcome (survival to hospital discharge) used the Charlson Index. Analyses used logistical regression.ResultsThe median Charlson Index was 1 (25-75%0-2). Overall survival was 43.9%. After adjustment for Utstein predictors, increase in cumulative comorbidity was associated with a dose-dependent decrease in the likelihood of survival. Compared to Charlson Score of 0, the odds ratio of survival was 0.68 (0.48-0.96) for Charslon of 1, 0.49 (0.35-0.69) for Charlson of 2, and 0.43 (0.30-0.61) for Charlson of >=3. This inverse comorbidity-survival association was similar for the other 2 scales and was observed for different clinical outcomes (admission to hospital, functional survival, 30-day survival, and 1-year survival).ConclusionBased on these results, cumulative comorbidity can help explain survival variability and improve prognostic accuracy. Whether information about cumulative comorbidity or specific health conditions can inform resuscitation care is unknown though the results suggest comorbidity may influence acute pathophysiology and treatment response.
