Acute kidney injury is one of the severe complications after burns. The purpose of this study was to identify prevalence, risk factors to the development of acute kidney injury (AKI) in burn patients and mortality, using RIFLE classification: risk (R), injury (I), failure (F), loss (L), and end-stage kidney disease (E). This 3-year retrospective study was conducted in burn patients admitted to the Dr. Soetomo Hospital Burn Center between January 2018 and September 2020. Burn patients aged >18 years old and diagnosed with acute kidney injury during hospitalization were enrolled in this study. Factors influencing AKI and its mortality were assessed using bivariate and multivariate logistic regression analysis. Eighty-nine burn patients were available for analysis, and 18 (20%) of them developed AKI according to the RIFLE classification: risk in 6 (33%), injury in 7 (39%) and failure in 5 (28%). Patients with AKI had a significantly higher age and % of TBSA than those without AKI (p-value <0.05). Age more than 60 years old was significantly associated as a risk factor to develop AKI (OR=25.553, p value=0.014). The mortality rate of patients with AKI was 83% (15 deaths from 18 patients), with the overall mortality of patients 16.8%. Chi-square analysis indicated inhalation injury, % of TBSA, and age as risk factors for mortality (p-value < 0.05). The conclusion of our study was that the incidence of AKI in burn patients was relatively high. Older age as a risk factor to develop AKI and inhalation injury, TBSA, and age were associated with mortality.
