Abstract 16922: Impact of Neighborhood Socio-economic Status on Bystander Cardiopulmonary Resuscitation in Paris

IntroductionThere is no European data on the impact of neighborhood socio-economic status (SES) on Out-of-Hospital Cardiac Arrest (OHCA) bystander CPR. This study aims to analyze, based on a robust deprivation index, neighborhood SES impact on bystander CPR.HypothesisWe hypothesize that OHCA victims in deprived area could be less likely to beneficiate a bystander CPR.MethodsData of all OHCA were collected prospectively between 2000 and 2010, in Paris. A geographical neighborhood unit was assigned to each case. Median household income, blue-collar workers rate, unemployment rate and adults without high school diploma rate were selected as SES characteristics and neighborhoods were classified in low SES neighborhood or medium- high SES neighborhood. We analyzed the relationship between neighborhood SES characteristics and the probability to receive bystander CPR.ResultsOf the 4,009 OHCA recorded with mappable addresses, 777 (19.4%) received bystander CPR. OHCA victims who received bystander CPR were more likely to be in public locations, with a witnessed cardiac arrest in neighborhoods ranged in low SES, or where median household income was in the highest quartile, and where no high school studies rate and blue collar worker rate were in the lowest quartile (p
