Background and Aim: Global scenario of antimicrobial (AM) utilization depicts 20–50% inappropriateness. Majority of the hospital admissions are due to unwanted effects because of non-judicial usage of these drugs. The present study focuses on utilization pattern of antimicrobials (AMs) in a tertiary care hospital in northern India. Materials and Methods: A prospective observational study was conducted over a period of one year in seven departments of a tertiary care hospital in hilly Himalayan region. Aim of the study was to analyze the AM utilization pattern using World Health Organization (WHO) indicators and instruments. Results: A total 700 prescriptions were analyzed in the present study. Injectable antibiotics (71%) followed by oral (29%) were most commonly prescribed. Beta lactams (79%) were the most frequently used antibiotic class. Most commonly prescribed AM was Ceftriaxone (30%). Majority of the time AMs were given empirically (44.8%), where most common indication was respiratory infections (42%). Culture and sensitivity tests were done for guiding curative therapy in 34.71% cases. The average duration of patient hospital stay was 8.81 days in the study population. The mean duration of prescribed antimicrobial treatment was 5.12 days. On an average 1.93 AMs were prescribed per patient. AMs were prescribed by International nonproprietary name (INN) in 62.19% of the admissions. The most common AM related adverse drug reaction was gastritis (96%) and skin rash (4%) with Amoxicillin + clavulanic acid being the most common causative agent. Total antimicrobial consumption was 148.24 DDD/100 bed days with Medicine department showing the highest consumption (36.25/100 bed days). Conclusion: The present study is the first and largest antimicrobial utilization study in the hilly Himalayan region of northern India. Our study found an urgent need for improvement of prescribing patterns, patient care indicators and strict adherence to standard guidelines.
