Does Acute Kidney Injury Condition Affect Revised BAUX Score in Predicting Mortality in Major Burn Patients?

Abstract

Objective: This study aimed to assess the accuracy of the revised BAUX score for predicting mortality among the major burn patients with acute kidney injury (AKI) compared with non-AKI group. The epidemiologic information and risk factors of AKI in major burn patients were also the point of interest. Methods: This study was a retrospective cohort study. The medical records of 144 major burn patients admitted at the burns unit of Siriraj Hospital from 2010-2016 were reviewed and important data were retrieved. Results: Age, hypertension, diabetes mellitus, severity of the burn injuries, and inhalation injuries were the factors related to AKI in major burn patients. The mortality rate due to AKI in burn patients was high (44.4%). The accuracy of the revised BAUX score in predicting the mortality among the major burn patients from our series was only fair (66.7%). Conclusion: AKI affected on mortality of the major burn patients. Until the better predictor comes up, the revised BAUX score should be considered as a predictor of mortality in these patients.
