Prevalencia de infecciones de la vía urinaria asociadas con catéter vesical en un hospital privado de tercer nivel.

OBJECTIVE: To evaluate the prevalence of catheter-associated urinary tract infection in all adult patients. MATERIAL AND METHOD: A cross-sectional and descriptive study in which cases of catheter-associated urinary tract infection were reviewed in Sanatorio Durango, Mexico City, from January 2015 to December 2016. All adult patients with a urinary catheter were followed up for more than 48 hours and the data were collected based on the reason for admission other than urinary infection, which was ruled out upon admission, as well as ensuring the recent non-intervention of urology and use of antimicrobials 14 days before hospitalization. RESULTS: There were included 1440 patients carriers of urinary catheter; of them, 75 patients were positive for catheter-associated urinary tract infection with an estimated prevalence of 5.2%, it was found an average time of infection development after 11.79 days of permanence of the catheter. E. coli producing extended-spectrum beta-lactamases was the main responsible for catheter-associated urinary tract infection (n = 30; 40%). Based on the statistical analysis, we found no correlation between the permanence of the urinary catheter and the development of infection. Regarding the time of hospital stay and the development of infection, no correlation was found in our institution. CONCLUSIONS: Being a urinary catheter carrier favors cases of urinary infection; however, other specific risk factors and the patient should be considered, responsible for the permanence of this complication in our hospitals.
