Abstract:
By a retrospective relative risk analysis for conditions associated with urinary tract infection over a four-year period in a defined teaching nursing home population (n = 97), we reached the following conclusions: (1) UTI was associated with cerebrovascular accident (relative risk 2.2, 95% confidence interval 1.4 to 3.2), decreased activities of daily living (relative risk 2.6 to 3.2, 95% confidence interval 1.4 to 4.7), decreased mental status (relative risk 2.2, 95% confidence interval 1.2 to 3.1), urinary catheterization (relative risk 2.5, 95% confidence interval 1.3 to 3.7), and antibiotic prophylaxis (relative risk 2.1, 95% confidence interval 1.2 to 3.0). (2) Risk of UTI from urinary catheterization and antibiotic prophylaxis was additive for these functionally impaired patients. (3) Renal insufficiency, diabetes, anemia, malnutrition, age, and incontinence (without catheterization) were not related to risk of UTI.
