Assessment of Aetiology and Risk Factors of Urinary Tract Infections in Geriatric Patients Admitted to the Surgery Department in Tertiary Care Hospital of West Bengal: A Cross-Sectional Study

Abstract

Background: Urinary Tract Infections (UTIs) are among the most common infections in the elderly population, often complicating surgical admissions due to comorbidities and age-related physiological changes. Understanding their aetiology and risk factors is essential for effective management and prevention. Objectives: To evaluate the underlying causes and associated risk factors for UTIs in geriatric patients admitted to the surgical department of tertiary care hospitals in West Bengal. Methods: A cross-sectional study was conducted on 32 geriatric patients (age ≥60 years) diagnosed with UTIs. Data on demographic characteristics, clinical history, comorbidities, and microbiological findings were collected. Statistical analysis identified significant risk factors and causative organisms. Results: The mean age was 68.4 years. Female patients (59.4%) had a slightly higher prevalence. The most common causative organism was Escherichia coli (62.5%), followed by Klebsiella pneumoniae (18.7%). Key risk factors identified included indwelling catheter use (68.7%), diabetes mellitus (53.1%), immobility (37.5%), and previous antibiotic use (31.2%). Conclusion: UTIs in the elderly surgical population are primarily caused by gram-negative bacteria, with catheterization and diabetes being the most significant risk factors. Proper catheter care, glycaemic control, and preventive strategies are necessary to minimize incidence.
