Abstract
This retrospective study aimed to identify the catheter-associated urinary tract infection rate and risk factors among patients admitted to a tertiary-care medical center in Bangkok.Participants included 994 patients with indwelling urinary catheters from October 1 to December 31, 2020. The research instruments comprised a personal information form and a urinary catheterization data collection form. Data were analyzed using descriptive statistics and logistic regression analysis. Results revealed that the catheter-associated urinary tract infection rate was 5.67 per 1,000 catheter days, 21.11 and 4.39 per 1,000 in private medical wards and the intensive care unit, respectively. The logistic regression analysis model revealed that factors predicting catheter-associated urinary tract infections were gender,heart failure, infection of other body parts,and urinary catheter days. These variables could jointly explain the variance in catheter-associated urinary tract infections by 39.20%.Participants with infection of other body parts had the risk of catheter-associated urinary tract infections 14.46 times significantly compared with those without infection when controlled for variables of gender,heart failure, and catheter days.Also, a 1-day increase in catheter days significantly increased the risk of catheter-associated urinary tract infections by 7% after controlling for other variables. Therefore, healthcare professionals should closely monitor patients requiring long-term indwelling urinary catheters and infections of other body parts. Re-evaluating the reasons for indwelling urinary catheters is necessary to reduce the riskof catheter-associated urinary tract infections.
