Prevalence and Risk Factors of Urinary Tract Infection in Hospitalized Hip Fracture Patients: A Cross-Sectional Study

Background Urinary tract infection (UTI) is a common complication among hospitalized patients with hip fractures. Several risk factors may increase the likelihood of UTI in this population and can lead to serious complications. This cross-sectional study aims to determine the prevalence of UTI and identify associated risk factors among hospitalized hip fracture patients at a tertiary public hospital in Thailand. Methods We conducted a retrospective cross-sectional study of 140 hospitalized patients with hip fractures from April 2016 to March 2025 and analyzed the prevalence of UTIs and associated risk factors. Logistic regression analysis was used to assess the odds ratio (OR) and 95% confidence intervals (CI). Results UTI occurred in 51 participants (36.4%) of hospitalized hip fracture patients. The mean age in the UTI group was 81.4 years, and UTI was more common in females. Female sex (OR 5.109; 95% CI 1.164 - 22.426), the Osteoporosis Self-Assessment Tool for Asians (OSTA) index ≤ -6 (OR 5.798; 95% CI 1.343 - 25.032), and the estimated glomerular filtration rate (eGFR) stage ≥ 2 (OR 8.946; 95% CI 1.477 - 54.178) were significant risk factors. Conclusion UTI was common among hospitalized hip fracture patients. Female sex, OSTA ≤ -6, and eGFR stage ≥ 2 were the main associated risk factors.
