Prevalência de microrganismos e resistência bacteriana em isolados de amostras do trato respiratório de pacientes internados em um hospital filantrópico da região do Vale do Rio Pardo.

Abstract

Infections related to health care are a serious public health problem that has generated an in-crease in morbidity, mortality and in the time of pacient’s hospitalization. The hospital envi-ronment offers a large reservoir of virulent and opportunistic agents, which are often resistant to most antimicrobials. The objective of this study was to analyze the demographic and clinical characteristics of patients admitted to a philanthropic hospital who were asked for cultural tests of the respiratory tract, as well as to characterize the isolated microorganisms and their resis-tance profile. Observational, cross-sectional and prospective study, carried out in a hospital in the Vale do Rio Pardo Region, from September to October of 2021. Information were collected regarding the patient and his hospitalization, as well as the agent responsible for the infection and his resistance profile. The study consisted of 26 patients and 39 TRI samples, 27 of which were positive with microbial growth. The average age was 64 years, the predominant sex was male (57.7%) and 88.5% of the participants used mechanical ventilation. All respondents had at least one type of comorbidity, cardiovascular being the most recurrent, affecting 50.0% of them. Regarding the microorganisms found, the most frequent were Enterobacter spp. (21.1%), followed by Stenotrophomonas maltophilia (13.2%) and Candida spp. (13.2%). As for the bac-terial resistance, 30.3% of the isolates were resistant to 3 or more different classes of antibiotics, 25.9% were classified as probable ESBL and 11.1% as probable producers of carbapenemase.
