RAK-PRIDE: Optimizing Proton Pump Inhibitor Use Through Education and Intervention

The goal of this study is to determine if a pharmacist-led educational intervention can reduce the inappropriate use of proton pump inhibitors (PPIs) among adult patients (≥18 years) with potentially inappropriate PPI prescriptions in Ras Al Khaimah. The main questions it aims to answer are: * Can a pharmacist-led education program reduce unnecessary PPI use? * Does the intervention improve patients' quality of life and reduce healthcare costs? Researchers will compare the intervention group (receiving pharmacist-led education and materials) to the usual care group to see if the intervention reduces PPI use and improves patient outcomes. Participants will: * Receive educational materials from pharmacists, including a patient educational brochure, PPI patient decision aid, PPI deprescribing pamphlet, and PPI patient action plan. * Physicians involved will also receive a pharmaceutical intervention, which includes a physician educational brochure, PPI evidence-based deprescribing guideline, PPI deprescribing algorithm, and whiteboard videos on PPI deprescribing. * Patients will be followed up for 6 months to monitor changes in PPI use, symptoms, and quality of life.
