Global Disparities in Burn Outcomes: Does Gender Predict Mortality in the Global Burn Registry?

      Abstract

      Introduction

      Global burn injury burden disproportionately impacts low- and middle-income countries. Surgery is a mainstay of burn treatment, yet access to surgical care appears to be inequitably distributed for women. This study sought to identify gender disparities in mortality and access to surgery for burn patients in the World Health Organization Global Burn Registry (GBR).

      Methods

      We queried the World Health Organization GBR for a retrospective cohort (2016-2021). Patients were stratified by sex. Outcomes of interest were in-hospital mortality and surgical treatment. Patient demographics, injury characteristics, outcomes, and health facility resources were compared between sexes with Wilcoxon rank sum test for nonparametric medians, and chi-squared or Fisher’s exact test for nonparametric proportions. Multivariable logistic regressions were performed to assess the relationships between sex and mortality, and sex and surgery.

      Results

      Of 8445 patients in the GBR from 20 countries (10 low resource), 40% of patients were female, with 51% of all patients receiving surgical treatment during their hospitalization. Female patients had a higher incidence of mortality (24% versus 15%, P < 0.001) and a higher median total body surface area (20% versus 15%, P < 0.001), yet a lower incidence of surgery (47% versus 53%, P < 0.001) following burn injury when compared to males. In multivariable analysis, female sex was independently associated with mortality after controlling for age, time to presentation, smoke injury, percent total body surface area, surgery, and country income status. Female sex was independently associated with surgical care (odds ratio 0.86, P = 0.001).

      Conclusions

      Female burn patients suffer higher mortality compared to males and are less likely to receive surgery. Further study into this gender disparity in burns is warranted.
