Background: Antimicrobial resistance (AMR) is a global concern requiring immediate attention. Among many proven measures of decreasing AMR, practice of antimicrobial stewardship is the lowest hanging which can be adapted with negligible financial implications. Methods: This is a case record based extended cross-sectional type of observational operation research study conducted at an institute of national importance established by Government of India. Point prevalence of antibiotic usage among the patients admitted in the hospital, on four different days in four different quarters of a year was done to study the impact of antimicrobial stewardship program (AMSP). Results: A cumulative 711 patients were exposed on antibiotics among 1396 study participants. There was a significant decrease in antibiotic consumption across the 1st and 4th quarter. The average antibiotic usage was 50.9% (61.75, 60%, 48.4%, and 39% respectively in the 1st to 4th quarter). Among the total number of patients, intravenous antibiotic usage was 47.9% (60.71%, 58.4%, 44.9%, and 34.2% respectively in 1st to 4th quarter). Among the newly admitted patients, the consumption of antibiotic usage decreased from 45.9% to 25.7%. Among the intravenous antibiotics, the top 10 consumed antibiotics were 3rd generation cephalosporin (39.8%), aminoglycoside (14.8%), amoxicillin/amoxy-clav (12.5%), piperacillin-tazobactum (8.5%), carbapenams (6.6%), cefuroxime (6.4%), quinolones (4.3%), vancomycin/linezolid (4.1%), colistin (0.8%), and others (0.8%). Conclusion: Government run hospitals can run low budget antimicrobial stewardship program with sustainable impact on antibiotic consumption. For a successful AMSP, it requires change in attitude, commitment, and administrative support rather than a huge financial support. |
