Objective: To evaluate rational drug prescribing practices in the surgical wards of a tertiary care hospital using World Health Organization/ International Network of Rational Use of Drugs (WHO/INRUD) prescribing indicators. Methods: A prospective observational study was conducted in general surgery wards of a tertiary care hospital over a six-month period. A total of 249 patients aged ≥ 18 years, with a hospital stay exceeding 24 hours were included. Data on drug prescriptions, including dose, frequency, and type, were collected from patient case notes and treatment charts. WHO/INRUD prescribing indicators were used to assess; average number of drugs per encounter, percentage of drugs prescribed by generic name, percentage of patient encounters with antibiotics and injections, and percentage of drugs from the national essential drug list (NEML). Results: The average number of drugs per encounter was 9.26, significantly exceeding the optimal level of ≤3. Only 14.22% of drugs were prescribed by generic name. Antibiotics were prescribed in 99.53% of encounters, far above the WHO-recommended 30%. The percentage of encounters with injectable drugs was 85.14%, and drugs from the NEML constituted 63.50%. Conclusions: The study reveals substantial deviations from WHO guidelines, with high rates of polypharmacy, low generic prescribing, and excessive antibiotic use. These practices heighten the risk of antimicrobial resistance (AMR) and underscore the need for effective antimicrobial stewardship programs. Hospitals should implement multifaceted strategies to improve antimicrobial use and align with WHO recommendations.
