There is little evidence about the relationship between neighborhood characteristics and survival from out-of-hospital cardiac arrest (OOHCA). We conducted a prospective observational study of consecutive patients within NYC from April 1, 2002-March 31, 2003. Data were collected from prehospital providers by trained paramedics. All OOHCA were geocoded to their neighborhood of residence (n=59). Overall, data was collected on 4653 OOHCA. Citywide OOHCA incidence was 7.6/10,000 adults and survival was 2.9%. Analyses were restricted to 2765 NYC residents with complete data available on all key variables. Survival from OOHCA among persons living in neighborhoods characterized by more unequally distributed income was 1.45%, compared to 2.93% for persons living in neighborhoods characterized by more equitable income distribution (p=0.01); persons living in wealthier neighborhoods had higher survival than those living in less wealthy neighborhoods (2.88% vs. 1.75%, p=0.02). In multivariable logistic models that accounted for demographics (patient age, race/ethnicity, prior cardiac history and functional status), OOHCA event characteristics (witnessed status, CPR receipt, initial cardiac rhythym), and median neighborhood income, living in a high income inequality neighborhood was associated with a lower likelihood of survival (p=0.01) than living in less inequitable neighborhoods. Those living in neighborhoods characterized by income inequality had a 23.2% lower chance of surviving OOHCA than persons living in neighborhoods characterized by one standard deviation more equitably distributed income. This study suggests that quality of the urban residential environment may be associated with OOHCA survival. Further work needs to determine etiologic factors underlying the observed associations.
