IntroductionLiterature examining the impact of obesity on burn injury remains mixed. Previous examination of the National Burn Repository, now the BCQP, in obesity-related burn research is limited. The aim of this work was to provide an assessment of the BCQP dataset to examine the effect of obesity on burn-related outcomes.Materials And MethodsA retrospective review of the BCQP dataset from 2015-2018 was conducted. The primary outcome measure was mortality. Secondary outcomes included overall length of stay (LOS), ICU LOS, and total hospital costs. Patients were grouped as obese or non-obese and were further stratified by total body surface area burned (TBSA) for comparison purposes. Multiple logistic regression (MLG) was used to compare the effect of several independent variables on mortality, ICU LOS > 7days, hospital LOS > 10 days, and total hospital costs > $200,000.ResultsOf 41,031 patients in the analysis, 3845 (9.37 %) were obese. Obese patients had a higher mean TBSA (p = 0.01), longer overall LOS (p < 0.001), ICU LOS (p < 0.001), and total hospital costs (p < 0.001). MLG found obesity to be an independent predictor of ICU LOS > 7 days, hospital LOS > 10 days, and total hospital costs > $200,000. Obesity was not an independent predictor of mortality in burn patients, even when stratified by burn size.ConclusionsThe presence of obesity in this dataset was not found to be a predictor of mortality for any burn size, but was a predictor of overall LOS, ICU LOS, and total hospital costs. Including obesity-related variables in databases may improve analysis in obesity-related burn research.Copyright © 2024 Elsevier Ltd and International Society of Burns Injuries. All rights reserved.
