Objectives: Unregulated and inappropriate use of antimicrobial agents has been a major driver of antimicrobial resistance with a dangerous impact on health issues in developing nations. We report an audit of antimicrobial use patterns in a tertiary-care teaching hospital in order to identify opportunities for antimicrobial stewardship. Methods: A point prevalence survey was conducted to study the use of ten selected antibiotics in various adult inpatient facilities. Patient characteristics as well as indications and patterns of antibiotic prescription were recorded. Results: A total of 188 patients received any one of the survey antibiotics, accounting for 43% of patients admitted under the study specialties. Of the 188 patients, 59% were admitted in non-intensive care unit settings. The median (interquartile range) duration of hospitalisation during the survey was 8 (4.75) days. Intra-abdominal infections (75; 40%) and respiratory infections (41; 22%) were the most common reasons for admission. Empirical antibiotic use was observed in 66% of patients. Antimicrobial use without any microbiological test was evidenced in 32 patients (17%). Significant differences were noted between medical and surgical specialties in choice of antibiotic, dosage and utilisation of microbiological tests. Conclusions: High empirical antibiotic use, poor transition from empirical to rational use, and underutilisation of microbiological tests were noted. The choice of antibiotics differed among specialties. Inappropriate dosing was greater in surgical specialties, especially with aminoglycosides. Adherence to local antibiotic policy, optimal dosing and audit of reserved antibiotic use can be useful approaches to strengthen antimicrobial stewardship programmes.
