The Impact of Multidrug-Resistant Organisms Infection on Outcomes in Burn Injury Patients at Sanglah General Hospital, Bali

Abstract BACKGROUND: Research related to the impact of multidrug resistant organisms (MDRO) infection on clinical outcomes in burns is still limited. AIM: This study evaluated the effect of MDRO infection on morbidity and mortality of burn patients. METHODS: A single-center retrospective cohort study was conducted on burn patients admitted to the burn unit of Sanglah General Hospital, Bali, between 2018 and 2020. MDRO patients were described as those who had at least one positive MDRO culture. All other patients were included in the non-MDRO group. Measurement and analysis included mortality and five indicators of morbidity: length of stay, duration of antibiotic therapy, sepsis, pneumonia, and acute kidney injury (AKI). RESULTS: Significant associations of MDRO infection were found for duration of antibiotic therapy (0 vs. 7 days), sepsis (odds ratio [OR] 13.90 [95% Confidence interval (CI) 95% 2.88–67.10]), pneumonia (OR 12,67 [95% CI 3.26– 49.23]), and mortality (OR 9.75 [95% CI 2.00–47.50]). No significant association was found for the length of stay and the incidence of AKI. Multivariate analysis found that MDRO infection increased risk of sepsis (OR 36.53 [95% CI 2.05–652.45], pneumonia (OR 10.75 [95% CI 1.87–61.86]) and mortality (OR 57.09 [95% CI 1.41–2318.87]). Multivariate analysis of MDRO infection with duration of antibiotic therapy found no independent variables that were significantly related. CONCLUSION: These research findings suggest that MDRO infections are associated with increasing length of antibiotic treatment, sepsis, pneumonia, and mortality in burn patients.
