Antimicrobial agents are the most common group of drugs prescribed, especially in inpatients, as well as contribute highest in the drug-related expenses. To gather an overview regarding the utilization pattern of antimicrobials among hospitalized patients, this retrospective study was conducted for the patients admitted in 2019. The present study was conducted at All India Institute of Medical Sciences Raipur, wherein the 600 medical records (50*12) of different departments for the year 2019 were chosen randomly for evaluation. Information regarding the number of beds, occupancy, demography, strength, route, and amount of drug that prescribed was noted for each month. Antimicrobial utilization was performed using the World Health Organization Anatomical Therapeutic Chemical/Defined Daily Dose (DDD) methodology. Antimicrobial drugs which were prescribed at least 5% of patients were evaluated in detail, and their prescribed daily dose (PDD) and anti-microbial consumption index was calculated and compared with their defined-daily dose. Monthly consumption of antimicrobials was noted and summed to get consumption for the whole year. Most of the records encountered while collecting data were of female patients, with an overall mean age of 42.4 years. Moreover, the records were largely from the patients who were admitted in either of the surgical departments. For the in-patients with an average duration of hospitalization of 6.56 days, the mean number of antimicrobials prescribed per prescription was observed to be 1.41. Highest consumption units were of ceftriaxone in 2019. The PDD of azithromycin and piperacillin + tazobactam was different from their DDD. For majority of antimicrobials, the calculated PDD was close to their DDD. The consumption was noted to be disproportionately higher in the 4 months of 2019 (September–December). Moreover, ceftriaxone was found to be prescribed routinely in the clinical practice.
