Abstract
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. coli and P. aeruginosa.
