Introduction. Urinary tract infections are the most frequent hospital
infections and account for about 40% of total hospital infections. The main
risk factor for their development is the use of catheters. Objective.
Assessment of basic epidemiological and etiological characteristics of
nosocomial urinary tract infections (NUTIs) and investigation of differences
in risk factors among the patients with NUTIs with and without the urinary
catheter. Methods. The study comprised patients treated in chosen units/ of
the Clinical Center in Kragujevac, in whom NUTI was registered during 2009.
Differences in risk factors for NUTIs between the catheterized and
uncatheterized patients were tested by the logistic regression analysis.
Results. NUTIs was registered in 162 patients whose average age was 66.2±13.5
years with approximately equal gender participation (51.2% men and 48.8%
women). Almost three quarters of the patients with NUITs had indwelling
urinary catheter, 12.0±7.7 days on average (from 1 to 39 days). In the
patients with urinary catheter, the risk for NUITs was significantly
positively associated with emergency admission to hospital treatment
(p=0.0185). The uncatheterized patients had a significant frequency of
malignant tumours comparing to the patients with a urinary catheter
(p=0.039). The compared groups did not differ in other risk factors. The
most frequently isolated microbial agents was Klebsiella spp (37.3%), then
Pseudomonas aeruginosa (14.1%) and Proteus mirabilis (11.9%). Most of the
bacteria showed a great level of resistance to frequently used antibacterial
drugs, even up to 100%. Conclusion. It is necessary to define national
recommendations for the prevention and control of NUTIs in the future.
