Postresuscitation risk\u2010standardized survival rates were calculated using predicted (hospital\u2010specific) to expected (population\u2010averaged) survival, reflecting whether post\u2013return of spontaneous circulation survival at a given hospital was better or worse than expected for an average hospital. Social Deprivation Index was assigned via ZIP\u2010to\u2010ZIP Code Tabulation Area linkage and analyzed by quartile.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      Of 686\u2009273 IHCAs, 206467 from 755 hospitals were included. Overall, 71\u2009691 (34.7%) survived to discharge. The median risk\u2010standardized survival rate was 33.9% (interquartile range, 32.6%\u201335.1%). The risk\u2010standardized survival rate varied substantially across hospitals (25.0% to 44.8%). Five hundred ninety\u2010five (78.8%) hospitals were linked to the Social Deprivation Index by ZIP code. Patients from hospitals in the lowest Social Deprivation Index quartile (least deprivation) had a higher postresuscitation risk\u2010standardized survival rate than those in the highest quartile (adjusted odds ratio, 1.13 [95% CI, 1.03\u20131.23];\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      &lt;0.01); the relationship across quartiles was not monotonic.
