ANALYSIS OF THE MICROBIOTA OF PATIENTS WITH PRESSURE INJURIES IN A TEACHING HOSPITAL

Abstract

Introduction: The chronicity of diseases and the development of chronic lesions trigger an increase in the incidence of patients with multidrug-resistant bacteria (MDR). Objective: To describe the microbiological profile of patients with pressure ulcers admitted to a teaching hospital. Method: This is a cross-sectional study with retrospective analysis of the results of safety cultures of 74 patients with chronic lesions, stages 3, 4 and unclassifiable, admitted to a medical, surgical, ICU and Onco-Hematology clinic at the University Hospital of Aracaju/SE, from January 2018 to December 2022. Results: Among the 74 patients selected for the study, 27 (36.5%) were female and 47 (63.5%) were male. Among the positive samples, 6 different microorganisms were identified, all of which were Gram-negative bacteria, identified as: Pseudomonas aeruginosa 4 (5.4%), Klebsiella pneumoniae 7 (9.5%), Enterobacter 2 (2.7%), Acinetobacter baumanii 2 (2.7%), Serratia marcescens 1 (1.4%) and Burkholderia sp 2 (2.7%). Conclusion: There is a clear need to investigate the presence of microorganisms in chronic pressure ulcers, since these agents are frequently identified in these patients, both in the short and long term, which can lead to complications and even death.
