Abstract
BACKGROUND: Catheter-associated urinary tract infections (CAUTIs) are the most common cause of hospital-acquired infections, especially in elderly patients. Data on CAUTIs in older persons in acute care settings are lacking, however. This study aimed to describe the epidemiology of CAUTIs and related outcomes (ie, length of stay and mortality), in patients admitted to an acute geriatric care hospital in central Italy. METHODS: A CAUTI surveillance program was implemented from October 2011 to April 2012, according to the Centers for Disease Control and Prevention's National Healthcare Safety Network methodology. RESULTS: A total of 2773 patients aged ≥65 years were included in the study, and 483 catheterized patients were monitored for the risk of CAUTI. The catheterization rate was 16.7% (95% confidence interval [CI], 15.3%-18.2%), and the overall CAUTI incidence rate was 14.7/1000 device-days (95% CI, 11.7-18.3/1000). Mortality was significantly higher in catheterized patients with a CAUTI compared with noncatheterized patients (19.2% vs 10.5%; P < .05). Female sex (odds ratio [OR], 1.31; 95% CI, 1.06-1.67), increasing age (≥90 years: OR, 2.76; 95% CI, 2.00-3.83), and longer hospital stay before catheter insertion (≥15 days: OR, 2.90; 95% CI, 2.20-3.83) were independent risk factors for catheterization; increasing age (>90 years: OR, 2.75; 95% CI, 1.03-7.35), and duration of hospital stay before catheter insertion (OR, 2.41; 95% CI, 1.12-5.51) were associated with CAUTIs. CONCLUSIONS: These results underscore the importance of the proper choice of patients for catheterization, particularly in individuals aged >90 years.
