Study design
A prospective, single blinded, randomized controlled study was conducted at one of the largest tertiary referral hospitals in Jordan, King Abdullah University Hospital (KAUH). The study was carried out during August 2020 till September 2021. The primary outcome determined in this study was the impact of a pharmacist-led educational intervention on adherence to short-term antibiotics among adult patients. A sample of 279 patients in each of the intervention and control groups was required to detect a 15% difference in adherence level between intervention and control group at 95% statistical power and at 5% significant level.
