title: Hospital-acquired urinary tract infection.
abstract: From 16,534 admissions, 60 patients, 4 days to 15 years of age, with one or more hospital-acquired urinary tract infections were identified during a 5-year period by a prospective surveillance system. The patient charts were subsequently reviewed to characterize the population at risk for such infections and to describe the course and consequences of these infections. Infections in individual patients ranged from one to greater than 50. The hospital-acquired urinary tract infection rate for the study period was 14.2 infections per 1,000 admissions. In the patients in whom all urinary tract infections were well documented, the following characteristics were defined: (1) 92% (97 of 105) of the infections occurred in catheterized patients; (2) almost half (49 of 105) of the infections occurred in patients exposed to only intermittent catheterization; (3) 28% (29 of 105) of the infections were asymptomatic; (4) fever was the most frequent finding in the symptomatic patients and occurred in 66% (60 of 105); (5) pyuria was found in only 51% (35 of 69) of the urinalyses performed at diagnosis; (6) 85% (89 of 105) of the infections were single-organism infections; (7) 82% (101 of 123) of the causative organisms were Escherichia coli, Pseudomonas sp, coagulase-negative staphylococci, Enterococcus spp, Klebsiella spp, or Enterobacter sp. The urinary tract infections in the 60 patients were not complicated by bacteremia, and no direct relationship between the infections and the minimal mortality in our patients could be established.
