Pattern of Antibiotic Use in Patients with Urinary Tract Infections at a Tertiary Care Hospital

Background: Urinary Tract Tnfection (UTI) is one of the most common bacterial infections worldwide. Inappropriate antibiotic prescribing, together with the increasing emergence of antimicrobial resistant organisms, compromises the effective management of urinary tract infections. This study aimed to evaluate antibiotic use patterns among patients with urinary tract, identify the most commonly prescribed antibiotics and assess empirical antibiotic use as well as antibiotic prescribing following culture and Antimicrobial Susceptibility Testing (AST). Materials and methods: This was an observational study conducted at Uttara Adhunik Medical College Hospital, Dhaka, Bangladesh from June to August 2025. A total of 94 culture-confirmed UTI patients were enrolled in the study. After obtaining informed written consent, epidemiological and demographic data were collected from each participant using a structured data collection form. The collected variables included age, sex, relevant clinical history and antibiotic prescription information. Results: UTI cases were reported more among middle-aged adults (35.11%). Higher proportion of females were affected by urinary tract infections in both indoor and outdoor cases. 32% of the total patients were received empirical antibiotic before culture and Antimicrobial Susceptibility Testing (AST). Escherichia coli (62.77%) was the predominant organism followed by Klebsiella pneumoniae (28.72%). 59.6% cases came as a follow up case who received prescribed antibiotics and the most prescribed antibiotics were ceftriaxone (26.79%) followed by meropenem (19.64%). Conclusion: Empirical antibiotic use was common among patients with urinary tract infections before culture and antimicrobial susceptibility testing, whereas antibiotic therapy after follow-up was guided by culture and AST results. Escherichia coli was the predominant uropathogen and ceftriaxone was the most commonly prescribed antibiotic after culture and AST. IAHS Medical Journal Vol 9(1), June 2026;91-96
