The objective is to assess risk factors and microbiological aspects of hospital-acquired urinary tract infection (HAUTI) on six wards of a general regional hospital in Serbia. A case-control study was nested within prospective cohort HAUTIs study conducted from January 1 to December 31, 2007. Three controls were identified for each patient with HAUTI, being chronologically the next three patients surveyed who did not develop HAUTI. The patients and controls were matched by sex and age (±5 years). Assessment of 8,467 patients during the study period revealed HAUTI in 125 (116 symptomatic and 9 asymptomatic). The overall incidence rate of HAUTI was 14.8 cases/1,000 admissions. The mean age (range) of cases and controls was 64.9 (18-85) and 65.2 (17-86), respectively. Multivariate logistic regression analysis showed that duration of catheterization >5 days (OR = 51.91; 95% CI = 23.46-114.82) and the ASA score (OR = 13.42; 95% CI = 2.14-84.30) were independently associated with increased risk of HAUTIs. The most frequently isolated Gram-negative bacteria were Enterobacter, Klebsiella sp., Proteus mirabilis and Escherichia coli. Enterococcus sp. was the most frequent Gram-positive bacteria.

Hospital readmissions are costly for patients and institutions. We conducted a study to evaluate rates of readmission within 30 days after anatomical total shoulder arthroplasty (ATSA) and reverse tot...
Bacteremia is an uncommon complication of urinary tract infection (UTI). The aim of this study was to identify risk factors for bacteremic UTI in pediatric patients.
To identify the potential risk factors for urinary tract infections following midurethral sling procedures.

This study consists of two studies with overlapping cohorts. One is a follow up epidemiological study of urinary incontinence, the other is a case control study of lower urinary tract dys...
Urinary tract infections are the most common type of hospital-acquired infection. The majority of these infections result from the use of indwelling urinary catheters. Often caregivers l...

An abnormal anatomical passage between the INTESTINE, and another segment of the intestine or other organs. External intestinal fistula is connected to the SKIN (enterocutaneous fistula). Internal intestinal fistula can be connected to a number of organs, such as STOMACH (gastrocolic fistula), the BILIARY TRACT (cholecystoduodenal fistula), or the URINARY BLADDER of the URINARY TRACT (colovesical fistula). Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (MEDICAL ERRORS).
Strains of Escherichia coli that preferentially grow and persist within the urinary tract. They exhibit certain virulence factors and strategies that cause urinary tract infections.
The presence of bacteria in the urine which is normally bacteria-free. These bacteria are from the URINARY TRACT and are not contaminants of the surrounding tissues. Bacteriuria can be symptomatic or asymptomatic. Significant bacteriuria is an indicator of urinary tract infection.
The non-susceptibility to infection of a large group of individuals in a population. A variety of factors can be responsible for herd immunity and this gives rise to the different definitions used in the literature. Most commonly, herd immunity refers to the case when, if most of the population is immune, infection of a single individual will not cause an epidemic. Also, in such immunized populations, susceptible individuals are not likely to become infected. Herd immunity can also refer to the case when unprotected individuals fail to contract a disease because the infecting organism has been banished from the population.
A surgical specialty concerned with the study, diagnosis, and treatment of diseases of the urinary tract in both sexes, and the genital tract in the male. Common urological problems include urinary obstruction, URINARY INCONTINENCE, infections, and UROGENITAL NEOPLASMS.
