Drug Utilization Pattern of Antimicrobial Agents in Medicine IPD of a Tertiary Care Teaching Hospital of Western Odisha

Abstract

Background: Around the world, doctors frequently prescribe antimicrobial agents (AMAs). However, irrational and inappropriate use of AMAs results in several negative outcomes, including antimicrobial resistance, connected health issues, lengthened hospital stays, and increased treatment costs. Antimicrobial resistance (AMR) is becoming a more serious global challenge in hospitals and communities. Hence, Drug Utilization Evaluation (DUE) studies are created primarily to evaluate and improve prescribing procedures and enhance the rational use of pharmaceuticals to address this significant condition. Materials and methods: A prospective observational study was conducted in a tertiary care hospital’s in-patient department of medicine. Analyses were done on the antibacterial agent drug usage patterns. Using Defined Daily Doses (DDDs) and Anatomical Therapeutic Chemical (ATC) Classification. The cost of the AMA therapy was estimated using the government’s approval rate for generic drugs. Results: Sixty-seven of the 100 patients were women, and 33 were men. Throughout the research period, 432 medications were prescribed, of which 39.8% were antibiotics and 77 % of patients had their AMA prescriptions based on data from bacteriological culture and sensitivity tests. The National List of Essential Medicines (NLEM) of India and the state essential drug lists were followed for prescribing the antimicrobial drugs by their generic names, respectively. In 27% of prescriptions, there was evidence of polypharmacy, and 70% of the combinations were logical. The patient spent 3.47 days in the hospital on average throughout their stay. It was discovered that antibiotics cost an average of Rs 200.17 per patient every day. Conclusion: Hospital antibiotic policy according to the ASP (Antibacterial Stewardship Programme) is essential for the optimization of antimicrobial therapy in this institution to ensure rational use of AMAs and to fight antimicrobial resistance.
