The incidence, clinical features and outcome of urinary tract infections in geriatric patients: A prospective longitudinal study
Abstract
Objectives: This study compares the incidence, clinical features, microbial profiles, and outcomes of urinary tract infections (UTIs) in patients aged 65 years and older versus those younger than 65 years. Methods: A longitudinal cohort of 1,123 patients was divided into Group A (≥65 years, n = 560) and Group B (<65 years, n = 563) and followed for 2 years. The study analyzed UTI incidence, clinical features, microbial profiles, and outcomes, including recurrence and antibiotic resistance. Results: species more common in recurrent UTIs, particularly in older patients. Risk factors for recurrent UTIs included advanced age, female sex, diabetes, immunosuppression, and renal stones. Conclusions: These findings highlight the need for age-specific UTI prevention and management strategies that account for microbial resistance patterns and higher recurrence rates in older patients, addressing clinical and microbial challenges.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 1,123 participants or records.
