Abstract

IntroductionWe sought to examine the impact of preexisting and new onset renal disease on burn injury mortality. MethodsRetrospective analysis of patients admitted to a regional burn center from 2002-2012 was performed. Variables analyzed included demographics, burn mechanism, inhalation injury status, and % TBSA. Poisson regression was performed to estimate risk of in-hospital burn mortality. ResultsThere were a total of 7640 patients over the study period. The adjusted 60-day risk of in-hospital mortality in patients with preexisting renal disease (PRD was 3 times higher compared to patients with no preexisting renal disease (IRR = 3.22, 95% CI = 1.26–8.25). The adjusted 60-day risk of mortality is 2 times higher for patients with new onset renal disease compared to those without (IRR = 2.11, 95% CI = 1.55–2.87). ConclusionPreexisting and new onset renal disease results in a significantly higher risk of mortality following burn injury compared to patients without renal disease. Prevention of new onset renal injury and careful management of patients with preexisting renal disease to prevent exacerbation should be pursued.
