Antibiotic Prescription Pattern among Primary Healthcare General Practitioners in the South Batinah Governorate of Oman, 2019

Abstract Background: Misuse and overuse of antibiotics comprise leading causes of antimicrobial resistance. The study aims to assess the pattern of antibiotic prescription among primary healthcare general practitioners in the South Batinah Governorate of Oman. Method: A cross-sectional study of 600 antibiotic prescriptions issued in the South Batinah Governorate in 2019 was conducted to verify the triggering diagnoses and determine the appropriateness of the prescribed antibiotic. Logistic regression analysis was used to determine the association between predictors and inappropriate use. Results: Respiratory infections accounted for 62% of antibiotic prescriptions, of which 92.2% were inappropriately prescribed. Extended-spectrum antibiotics were inappropriately prescribed in 33.3% of cystitis cases, while 14.3% of gastroenteritis received incorrect spectrum of antibiotics. Amoxicillin represented 46.2% of antibiotic prescriptions, of which 84.4% were unnecessarily prescribed. Lower inappropriate antibiotic prescribing rate was linked to patients ≥ 18 years (OR = 0.46, 95% CI: [0.26, 0.82]), those who underwent laboratory tests (OR = 0.22, 95% CI: [0.12, 0.39]), and consultations at health centers (OR = 0.44, 95% CI: [0.24, 0.79]). Arabic-speaking physicians were more likely to prescribe antibiotics inappropriately. Conclusion Inappropriate antibiotic prescription was frequently observed in mild respiratory infections and associated with specific patient and physician characteristics. The implementation of healthcare center antibiotic stewardship initiatives, would help to promote appropriate antibiotic prescriptions.
