THE EFFECT OF MULTIDRUG-RESISTANT ORGANISM INFECTION ON MORTALITY OF BURN PATIENTS AT RSUPN DR. CIPTO MANGUNKUSUMO.

Susceptibility to infection and increased antibiotic resistance place burn patients at risk of infection caused by multidrug-resistant organisms (MDRO). This condition can progress to sepsis, which can increase morbidity and mortality. A retrospective cohort study using medical record data of patients treated at RSUPN dr. Cipto Mangunkusumo in the period January 2020 to June 2022 was conducted. Of a total 160 subjects in the study period, 82.5% were aged <60 years, 16.88% had comorbidities, the most common cause of burns was fire (86.25%), the use of medical devices was 90.63%, with a median length of stay of 14 days. The most common Gram-negative MDRO pathogens were K. pneumoniae (29.91%), Enterobacter sp (22.32%) and Acinetobacter (20.54%): 45% of MDRO infected patients died. Bivariate analysis was conducted to find the effect of MDRO infection on burn patient mortality (RR 1,103; 95% CI 1,004-1,211, p=0.046). After adjusting for the role variables, namely: age, comorbidities, TBSA, use of medical devices, length of stay and multivariate analysis, it was found that the variables that had an effect on MDRO infection mortality were length of stay and age. MDRO infection has an effect on the mortality rate of burn patients. Mortality of burn patients due to MDRO infection is greater (45%) compared to non MDRO (21.43%). The most common Gram-negative MDRO pathogen is K. pneumoniae.
