INTRODUCTION: Severe burns significantly weaken the immune system and disrupt the skin's natural barrier, which increases the likelihood of healthcare-associated infections (HAIs) and raises the risk of mortality.
METHODS: Based on CDC criteria, this study retrospectively examines the incidence of HAIs in burn patients hospitalized at a university hospital in São Paulo, Brazil, over five years from 2018 to 2022.
RESULTS: 536 patients were treated during this time, with 130 HAIs recorded in 88 individuals. The average age of the patients was 41 years, and the mean total body surface area (TBSA) affected by burns was 20.4%. The primary causes of burns were flammable liquids (39.7%), electrical injuries (25%), and scalds from heated liquids (14.8%). Burn wound infections were the most frequent HAI (51.5%), followed by bloodstream infections (13.8%), urinary tract infections (13.1%), and ventilator-associated pneumonia (10.7%). Regarding microbiological findings, 141 microorganisms were isolated, with gram-negative bacteria making up 71.6% of the total, gram-positive bacteria accounting for 21.2%, and fungi representing 7.1%. In three cases, no microorganism was identified. The mortality rate among these patients was 13,6%.
CONCLUSION: Notably, the predominance of gram-negative bacteria in this population, responsible for more than 70% of infections, contrasts with findings from other studies. The findings highlight the importance of infection control to reduce morbidity and mortality in this vulnerable population.
