INTRODUCTION: Early excision and grafting remains the standard of care after burn injury. However, in a resource-limited setting, operative capacity often limits patient access to surgical intervention. This study sought to describe access to excision and grafting for adult burn patients in a sub-Saharan African burn unit and its relationship with burn-associated mortality.
METHODS: We analyzed patients recorded in the Kamuzu Central Hospital Burn Registry in Lilongwe, Malawi from 2011-2019. We examined patient characteristics, interventions, and outcomes for adults aged ≥16 years. Modified Poisson regression modeling was used to identify risk factors for mortality.
RESULTS: Five hundred and seventy-three patients were included. Median age was 30 years (IQR 23-40) with a male preponderance (63%). Median percent total body surface area burned (%TBSA) was 15% (IQR 8-26) and 68% of burns were caused by flame. 27% (n = 154) had burn excision with skin grafting, with a median time to operation of 18 days (IQR 9-38). When adjusted for age, %TBSA, and time to presentation, operative intervention conferred a survival benefit for patients with flame burns with a RR 0.16 (95% CI 0.06, 0.42).
CONCLUSIONS: In a resource-limiting setting, access to the operating room is inadequate, and burn patients are not prioritized. While many scald burn patients may be managed with wound care alone, patients with flame burn require surgical intervention to improve clinical outcomes. Burn injury in this region continues to confer a high risk of mortality, and more investment in operative capacity is imperative.
