Background:
Urinary tract infections (UTI) in patients with urinary catheters could be a serious complication of hospitalisation in the intensive care unit (ICU).
Methods:
A prospective study (01.01.2012-31.12.2014) was conducted in the 20-bed ICU of the University Hospital in Wroclaw, Poland. The frequency (density, incidence) and aetiology of UTI as well as prophylactic method compliance were estimated in patients of the ICU according to the INICC project.
Results:
Among 1261 ICU patients, urinary tract infections were diagnosed in 91 (7%). The incidence index was 7.25/100 admissions to the ICU. CA-UTI constituted 36% of the device-associated, healthcare-associated infections (n = 255). A urinary catheter was used in 92.21 ± 4.51% of patients during 14,006 patient-days and 12,917 urinarycatheter- days. The density of CA-UTI/1000 catheter-days was 6.44, 6.84, 7.16 during the years 2012, 2013, and 2014, respectively. The main pathogens of CA-UTI were Enterococcus spp. (22%), Acinetobacter baumannii (20%), Klebsiella pneumoniae (18%), Pseudomonas aeruginosa (13%), and Candida spp. (13%). Only in four elements of the "Urinary Catheter Bundle" was 100% compliance noted.
Conclusions:
In the observed period of time, the incidence of CA-UTI was higher than in the INICC (2014) report and the NHSN/CDC (2012) report. Analysis of compliance with a "Urinary Catheter Bundle" to prevent UTI shows low implementation of preventative methods with the INICC protocol.
