Infection in hospitals is a serious problem for the Public Health System. It is responsible for the increasing number of hospital deaths, as well as the longer time patients may have to stay in hospital, raising the costs of confinement more and more. The most common hospital infection is urinary tract infections (UTI), the use of the urinary catheter being the main risk factor. The aim of this study was to evaluate the profile of UTI among hospitalized patients in a University Hospital in Brazil, from October to December 2003. Out of 271 samples of urine checked, 51 were positive, 27 of these from patients having community-acquired UTI and 24 whose infection originated in the hospital. The community-acquired UTIs were more frequent in female patients (63%). The highest incidence of infection was caused by Escherichia coli (74%), especially in patients aged from 0 to 15 (37%). The episodes of hospital-acquired infection happened, in the main, in male patients aged above 50 (68%) who were using a lasting vesical catheter; in this group of patients the infection was frequently caused by E. coli (29.1%) and Klebsiella spp. (29.1%). E. coli and Klebsiella pneumoniae exhibited strong resistance (62.5%) to trimethoprim-sulfamethoxazole, as well as to ampicillin, showing that these drugs should not be used to cure UTIs in this institution.

Laboratory tests to detect urinary infection at a lawer cost than uroculture are necessary. Triphenyl tetrazolium chloride was evaluated in parallel with uroculture in 342 urine samples, for the detection of significant bacteriuria. The results showed that the test has high sensitivity (91.3%) but low specificity (64.3%), and negative predictive value 99.0%. Although the test cannot replace uroculture as a diagnostic method, it can be recommended for preliminary screening, and could eliminate the need for uroculture of negative samples.
