Deprivation was assessed using the Area Deprivation Index. Both were derived from US Census data and grouped by EMS agency.<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n Outcomes were restoration of spontaneous circulation (ROSC) at emergency department (ED) arrival, survival to hospital discharge, and favorable discharge destination. Discharge outcomes were only available for patients transported to hospitals using health data exchange. Generalized estimating equations were used to account for correlated data.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n A total of 162\u202f289 patients with OHCA had resuscitation attempted (median [IQR] age, 66 [53-76] years; 62.3% male). Overall, 28.1% of these patients lived in rural or suburban locations, 12.3% lived in areas with high deprivation, 18.7% had a first rhythm of ventricular tachycardia or ventricular fibrillation or shockable by automated external defibrillator rhythm, and 27.6% received bystander cardiopulmonary resuscitation. The mean (SD) EMS response time was 8.7 (5.6) minutes. Upon arrival at the ED, 23.7% of patients had ROSC. Compared with OHCAs in urban areas with low deprivation, those in rural areas with high deprivation (adjusted odds ratio [AOR], 0.81; 95% CI, 0.72-0.91), moderate deprivation (AOR, 0.75; 95% CI, 0.70-0.81), or low deprivation (AOR, 0.74; 95% CI, 0.62-0.88) had lower odds of ROSC at ED arrival. Among patients transported to hospitals using health data exchange, OHCAs in urban areas with high or moderate deprivation had lower odds of survival (AOR, 0.78 [95% CI, 0.68-0.90] and 0.82 [95% CI, 0.75-0.89], respectively) and favorable discharge destination (AOR, 0.65 [95% CI, 0.53-0.79] and 0.77 [95% CI, 0.69-0.87], respectively).<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n In this cohort study, OHCAs in rural areas of all levels of economic deprivation were associated with less ROSC at ED arrival vs urban areas with low deprivation, and OHCAs in urban areas with high or moderate deprivation are associated with less survival and less favorable discharge destination, suggesting worse neurologic outcomes. Care improvements alone may not reduce geographic differences in outcomes after OHCA.<\/jats:p>\n
