OBJECTIVES:The purpose of this study was to determine whether gender differences exist in the characteristics and outcomes for out-of-hospital cardiac arrest (OHCA) occurring in a rural setting.BACKGROUND:In urban settings,women have a lower incidence of OHCA than men but otherwise a comparable survival for ventricular fibrillation (VF) OHCA.Whether OHCA gender differences exist in rural settings is not clear.METHODS:The study consisted of a prospective collection and analysis of nontraumatic,adult OHCA prompting a 911 call in six rural Indiana counties.RESULTS:Over an average period of 2.2 years,138 women and 250 men experienced OHCA (annual incidence rate:56.4 per 100,000 men and 29.3 per 100,000 women).Women were older,less likely to experience OHCA in a public setting,more likely to be in an extended care facility,and less likely to have a witnessed arrest than were men.Women were less likely to present with an initial rhythm of VF than men (33.3% vs 53.6%,P < .001).Women in VF had a longer time interval from 911 call to first shock compared with men.Women had poorer survival to hospital discharge for all OHCA (2.2% vs 7.2%,P = .04) and VF OHCA (2.2% vs 13.4%,P = .05) compared with men.After age adjustment,female gender remained associated with a poorer OHCA survival outcome.With adjustment for all significant arrest characteristics,female gender was no longer associated with survival.CONCLUSIONS:In a rural population,women suffering OHCA have a dismal survival rate likely because of multiple unfavorable arrest characteristics.
