Abstract

The majority of the burden of firearm injury in the United States is on men as compared to women. There is limited evidence regarding sex differences in short-term hospitalization outcomes after surviving firearm injury. The risk of cardiovascular and all-cause hospital readmission, length of stay (LOS), and costs within 180 days after surviving an index firearm injury was compared between males and females. A claims-based, retrospective, cohort study was performed using Nationwide Readmission Database (2013-2014) to obtain a cohort of patients who survived an index hospitalization of firearm injury. The analysis was performed in August 2017. Cox proportional hazard regression models were used to estimate hazard ratio (HR) and 95% confidence intervals (95% CIs). Among 17,594 males and 2,289 females discharged alive after index firearm injury hospitalization, 14.4% and 13.2% were readmitted within 180 days. Within 180 days, the risk of cardiovascular readmission was 3.3 times greater among males versus females (HR = 3.34, 95% CI [1.18, 9.44]. Risk of all-cause readmission among males was greater at 90 days (HR = 1.40, 95% CI [1.04, 1.87]. Patients surviving a firearm injury have a substantial risk of subsequent hospitalizations. Cardiovascular readmissions are greater among males than females during the first 6 months after injury and may be indicative of a continuing long-term risk of health and patient outcomes that contributes to the overall burden of firearm injury.
