Race and Survival After Cardiac Arrest—Reply

JAMA. 2010;303(2):130-131. doi:10.1001/jama.2009.1967

In Reply: Dr Dezfulian and colleagues raise the question of whether racial differences in survival after in-hospital cardiac arrest are greatest in the top performing hospital quintile, which has the lowest hospital proportion of black patients with cardiac arrest. We did not find that racial differences in survival differed significantly across hospital quintiles (P = .65 for interaction). In part, this is because black patients comprised only 3% of patients in the quintile with the lowest hospital proportion of black patients1; thus, the extent of racial differences in this quintile was imprecise, as illustrated by the wide 95% confidence interval.
