Catheter-associated urinary tract infections (CAUTIs) occur at similar rates in the
intensive care unit (ICU) and in non-ICU settings, according to a new study.
intensive care unit (ICU) and in non-ICU settings, according to a new study.
Researchers at Duke University Medical Center in Durham, N.C., analyzed CAUTI
surveillance data from 15 community hospitals in the Duke Infection Control
Outreach Network over a two-year period (January 1, 2010 to December 31,
2011).

During the study period, 506 CAUTIs occurred over 312,946 catheter-days and
1,331,280 patient-days during the 24-month study period. Only 143 of the CAUTIs
(28%) occurred in ICU patients. The overall CAUTI rate was 1.6 per 1,000
catheter days, according to the investigators. The rates of CAUTI in the ICU and
non-ICU patients were 1.83 and 1.55 cases per 1,000 catheter days, respectively,
a non-significant different between the groups.

“Overall, we found that three quarters the catheter-associated urinary tract
infections occurred outside the intensive care unit,” said lead investigator
Sarah Lewis, MD, an infectious diseases fellow at Duke. “It was a little bit of
a surprise because we traditionally think of the ICU as being the most high-risk
hospital location for these infections. We often think that ICU patients are
sicker and have more medical comorbidities, which make them more susceptible to
hospital-acquired infections.”

CAUTIs are the leading cause of hospital-acquired infections in the United
States, Dr. Lewis said. Surveillance and prevention initiatives, however, mainly
have focused on patients in the ICU. The epidemiology of CAUTIs in non-ICU
settings and in community hospitals has not been well documented, she noted.

“We may need to reframe our prevention efforts and initiatives,” Dr. Lewis
told Renal & Urology News. “We may need to look more specifically
what is different between ICU and non-ICU patients and target things differently
outside the ICU than we do in the ICU to prevent catheter-associated urinary
tract infections.” She presented study findings at IDWeek, a joint meeting of
the Infectious Diseases Society of America and three other medical
societies.

The most common pathogens were Escherichia coli (24%), Enterococcus
species (20%), Candida species (20%), and Klebsiella species
(7%). In addition, 8% of the pathogens exhibited multiple drug resistance. The
researchers observed no major differences in causative organisms when comparing
ICU and non-ICU patients, except for Candida species, which were observed
more often in ICU patients.
