Drug Utilisation Pattern of Antimicrobial Agents Prescribed for Urinary Tract Infection in Geriatric Patients at a Tertiary Care Hospital: A Retrospective Study

Abstract Introduction: Drug utilisation studies may lead to several perspectives such as the correct usage of drugs and appropriateness of drug utilisation. Prescription indicators are used to assess the effectiveness of healthcare practitioners in several critical characteristics connected to drug usage. Objectives: 1. To determine the most commonly prescribed antimicrobial agents for treating UTI in Geriatric patients.2. To analyse prescriptions in comparison with WHO prescribing indicators. Methods: All the cases of UTI in geriatric patients with positive urine culture report in the past 6 months (Feb 2023 –July 2023) were included and it was a complete enumeration study. Discrete variables and Categorical variables were represented by percentage. Continuous variables were expressed in mean ± SD. Result: Total of 70 geriatric patients with UTIs were enrolled in the study. Of these male Patients were 31 (44.28%) and female Patients were 39 (55.71%). No of antibiotics per Prescription was 1.97± 1.43. Approximately 40.54% of medications were prescribed using their generic names. About 79.27% of medications were prescribed from the NLEM. 62.16% of drugs were prescribed by injection. systemic hypertension (67.74%) was observed in the majority of UTI patients. Piperacillin + Tazobactam were the most prescribed antibiotics. Duration of hospital stay was 10.22±6.71 days. Conclusion: By addressing these findings, we can enhance the pharmacological management of UTIs in geriatric populations, leading to improved patient outcomes and quality of care.
