Effect of a workshop in rational pharmacotherapy for interns during family medicine clerkship in Samsun- Turkey

Objective: We aimed to investigate the effect of rational pharmacotherapy workshop for interns on the rationality, cost and number of drugs prescribed. Methods: The participants were asked to prescribe a medication for acute noninflammatory osteoarthritis (ANOA), acute bacterial rhinosinusitis (ARS), acute otitis media (AOM), acute uncomplicated cystitis (AC), and acute bacterial tonsillopharyngitis (ABT) before and after workshop. Total 3000 prescriptions were scored regarding rationality of the drug choice (0-10), format (0-5), instructions (0-4), legibility (0-1) and total (0-20 points). The mean number of drug(s) and total costs per prescription were calculated. Paired samples t-test was used to compare the pre- and post score means. Results: Total pre- and post-prescribing scores (0-20) were significantly different (p=0.00 for each): ANOA (13.59±0.27, 18.33±0.18), ARS (13.26 ±0.18, 15.15 ±0.17), AOM (12.58 ± 0.26, 14.66±0.27), AC (13.53±0.17, 15.76±0.20), ABT (13.54±0.24, 15.49 ±0.28). Mean number of drugs per prescription for the indications in the pre-test and post-test were: ANOA (1.24 ±0.29, 1.02±0.01, p=0.00), ARS (2.08±0.04, 2.00±0.04, p=0.16), AOM (1.66±0.04 and 1.69±0.03, p=0.54), AC (1.55±0.04, 1.39±0.03, p=0.00) and ABT (2.10±0.05, 1.81±0.05, p=0.00). Mean costs per prescription in Turkish Liras: ANOA (6.31±0.29, 4.60±0.05, p=0.00), ARS (13.80±0.38, 4.63±0.04, p=0.00), AOM (10.18±0.28, 4.41±0.07, p=0.00), AC (11.33±0.21, 10.68±0.18, p=0.01) and ABT (12.03±0.34 and 10.41±0.35, p=0.00). Conclusion: Training produced a significant improvement in rational prescribing.
