Highlights
- •We aimed to determine risk factors for urinary tract infection (UTI) in ICU patients to inform potential interventions.
- •We compared 90 cases of UTIs with 90 patients with asymptomatic bacteriuria and 344 uninfected controls.
- •UTIs tended to occur early in the course of ICU admission, and were more common in surgical patients
- •Risk factors included catheter placement in emergency or the operating room.
Abstract
Introduction
Urinary tract infections (UTI) are common in intensive care units (ICU) due to the
high prevalence of urinary catheters. We aimed to determine risk factors for urinary
tract infection to inform potential interventions to reduce this infection in ICU
patients.
Methods
We performed a case-control-control study to determine risk factors for symptomatic
UTIs, compared to asymptomatic bacteruria and control patients.
Results
We identified 90 patients with symptomatic urinary tract infections and 90 patients
with asymptomatic bacteriuria, and 344 control patients without bacteriuria or urinary
tract infection between January 2007 and August 2009. A higher proportion of patients
with symptomatic UTIs had catheters placed in emergency or the operating theatres
than in ICU. The risk of infection increased with increasing APACHE 2 score. The median
duration of admission prior to symptomatic UTI was 6 days, and asymptomatic bacteriuria
was 9 days.
Discussion
UTIs tended to occur early in the course of ICU admission, and were more common in
surgical patients, particularly where the catheter was placed in emergency or the
operating room.
