Association Between Male Sex and Increased Mortality After Falls

Objectives Whether sex affects the mortality of trauma patients remains unknown. The hypothesis of this study was that sex was associated with altered mortality rates in trauma. Methods A retrospective review of trauma patients’ records in the Japan Trauma Data Bank was conducted (n = 80,813) from 185 major emergency hospitals across Japan. The primary outcome variable was in‐hospital mortality within 28 days. Secondary outcome variables included serious injuries to different body regions with an Abbreviated Injury Scale of ≥3. Results In the analysis of 80,813 trauma patients, males had significantly greater 28‐day mortality compared to females (adjusted p = 0.0072, odds ratio [OR] = 1.14, 95% confidence interval [CI] = 1.06 to 1.23) via logistic regression analysis adjusted for age, mechanism, Injury Severity Score, Revised Trauma Score, and potential preexisting risk factors. Of 10 injury categories examined, sex significantly affected in‐hospital 28‐day mortality rate in falls (adjusted p
