Infección urinaria relacionada con sonda uretral en pacientes críticos ingresados en UCI. Datos descriptivos del estudio ENVIN-UCI

Objective: To describe trends in national catheter-related urinary tract infection (CRUTI) rates, as well as etiologies and multiresistance markers..Design: An observational, prospective, multicenter voluntary participation study was conducted from 1 April to 30 June in the period between 2005 and 2010.Setting: Intensive Care Units (ICUs) that participated in the ENVIN-ICU registry during the study period.Patients: We included all patients admitted to the participating ICUs and patients with urinary catheter placement for more than 24 hours (78,863 patients).Intervention: Patient monitoring was continued until discharge from the ICU or up to 60 days. Variables of interest: CRUTIs were defined according to the CDC system, and frequency is expressed as incidence density (ID) in relation to the number of urinary catheter-patients days.Results: A total of 2329 patients (2.95%) developed one or more CRUTI. The ID decreased from 6.69 to 4.18 episodes per 1000 days of urinary catheter between 2005 and 2010 (p<0.001). In relation to the underlying etiology, gramnegative bacilli predominated (55.6 to 61.6%), followed by fungi (18.7 to 25.2%) and grampositive cocci (17.1 to 25.9%). In 2010, ciprofloxacin-resistant E. coli strains (37.1%) increased, as well as imipenem-resistant (36.4%) and ciprofloxacin-resistant (37.1%) strains of P aeruginosa.Conclusions: A decrease was observed in CRUTI rates, maintaining the same etiological distribution and showing increased resistances in gramnegative pathogens, especially E. call and aeruginosa.
