International Journal of Environmental Research UTI Study

This research article, published in the International Journal of Environmental Research and Public Health, presents a retrospective cohort study examining the incidence and risk factors for urinary tract infections (UTIs) in an elderly home care population in Taiwan. The study included 598 patients who received home care for at least three months in 2017. A UTI episode was defined by admission for UTI treatment or outpatient visits with antibiotic prescriptions. The findings revealed a 47% overall incidence of UTIs. The most significant risk factor identified was urinary catheter indwelling, followed by underlying diseases such as coronary artery disease, chronic kidney disease, and diabetes mellitus. Other related factors included polypharmacy and lower Barthel index scores. Higher albumin and hemoglobin levels were inversely associated with UTI. The study concludes that apart from unmodifiable factors, avoiding prolonged urinary catheter placement, unnecessary prescriptions, and maintaining good nutritional status may help prevent UTIs in home care patients. The study highlights the importance of preventative strategies to improve the quality of home care for the elderly population.
