Infecção do trato urinário associada ao cateter vesical em unidade de terapia intensiva

Abstract

Background and Objectives: Urinary tract infections (UTI) related to the use of long-term urinary catheter (LUC) (ITU-LUC) present high prevalence in intensive care units (ICU). Therefore, the objective of the present study is to determine the prevalence and factors associated with UTI-LUC at ICU. Methods: Retrospective documentary research with quantitative approach conducted by the analyses of medical records from all patients admitted to the ICU from a University Hospital located in the north region of the State of Minas Gerais, from January 2013 to December 2014. Data collection and analysis were based in the medical records and notification sheets of healthcare-associated infections (HAI). Poisson regression was adopted with a 95% confidence interval. Results: From 169 patients analyzed, 145 (85.8%) underwent bladder catheterization. The prevalence of UTI-LUC was 16.6%. The factors associated were hospitalization time ≥ 15 days (prevalence ratio: 4.6) and use of urinary catheter ≥ 10 days (prevalence ratio: 7.4). Conclusion: Time of hospitalization and LUC permanence was directly related to the occurrence of UTI-LUC, pointing out to the commitment of health care professionals in the monitoring of time of hospitalization, continuous evaluation and strict indication of LUC use.
