Infecção do trato urinário em pacientes internados em clínica médica de um hospital universitário

Abstract

Objective : The aim of this study was to evaluate the incidence and the factors related to catheter-associated urinary tract infection in adults who were hospitalized in the internal medicine service, and to identify catheter utilization rates, frequency of the register of order of insertion and removal, adequacy of use in terms of indication, and catheter vesical length of permanence. Method : This is a prospective cohort study conducted at a university hospital in Minas Gerais. Univariate analyses were performed using the chi-squared test or Fisher’s exact test for categorical variables, and the non-parametric Mann-Whitney test for numerical variables. Results : In ten months, 1121 patients were admitted, 63 (5.6%) of these used the vesical catheter, being 880 urinary catheters/day. The incidence of catheter-associated urinary tract infection was 31.7%. The results showed positive associations between the occurrence of urinary tract infection with the length of permanence and time of use of the vesical catheter. Conclusion : The use of urinary catheters should be limited to carefully selected patients, followed by a safe insertion and maintenance, and removed promptly, when no longer required, in order to ensure patients’ safety.
