Assessing Drug Utilization in the Emergency Medicine Department at a Tertiary Care Teaching Hospital Using WHO Drug...

Background Patients might need urgent care in critical cases. Limited resources and limited manpower are limitations seen in developing countries. Very few studies have been conducted on drug utilization in the emergency department in Nepal. Objective To find out the drug utilization pattern and the cost of medicines in emergency medicine department as per WHO drug use indicators. Method The study design was a hospital based retrospective cross-sectional study done at the emergency department of KIST Medical College and Teaching Hospital, Lalitpur, Nepal. The study population were patients visiting the emergency department. The data was collected during the period from April to June 2023. Data was collected for one month from each quarter for the year 2023 from the medical records of the patients from the medical records section. A structured proforma was used for the data collection process. Census sampling method was used. Result Maximum patients, 257 (25.1%) were from age group 21-30 years. Females were slightly more than males, 537 (50.5%). The top three diagnosis among the admitted patients were soft tissue injury, 148 (13.9%), dengue fever, 138 (12.9%) and viral fever, 51 (4.7%). Maximum patients, 346 (32.5%) were given two therapeutic classes of drugs, followed by only one therapeutic class of drug for 251 (23.6%) patients. The common classes of drugs prescribed for the patients were analgesics, 639 (60.1%) followed by intravenous fluids, 410 (38.5%) and antiulcer drugs, 377 (35.4%). The total cost of drugs used was calculated as Rs. 305126.4 (2280.99 USD) and the average cost per patient was Rs. 297.97 NPR; 2.23 USD. The WHO drug prescribing indicators showed maximum percentage, (85.4%) of encounters with injection prescribed followed by the percentage of drugs prescribed from the Nepalese National List of Essential Medicines 81.71%. Conclusion On the basis of the findings from this study injection prescribing, and the number of drugs prescribed per encounter showed considerable deviation from the standards recommended by the WHO. Hence, it is important for the hospital to design and implement a system to promote judicious prescribing and injection medication administration.
