Abstract
Background: Prescribing appropriate medications for geriatric patients is one of the greatest challenges for healthcare professionals in both inpatients and outpatient settings. There is an important need for improving the physicians’ knowledge of drug therapy in geriatric patients to improve the healthcare system performance and serve the people using the system. Aim: This study aimed to assess the effectiveness of an educational intervention targeting prescribers in improving knowledge of potentially inappropriate medication (PIM) use among hospitalized geriatric patients. Methodology: A prospective pre test–post test quasi experimental study was conducted among physicians in the Department of Medicine at King Abdulaziz Medical City, Riyadh. A validated self administered questionnaire comprising 18 PIM knowledge questions based on the Beers and STOPP Criteria was completed before and after a structured educational session. Results: After the educational intervention was implemented, the proportion of physicians with good knowledge increased significantly from 21.6% to 63.5% (p < 0.001). Conclusion: The findings of this study suggest that the educational intervention was associated with an improvement in physicians’ knowledge of geriatric pharmacotherapy.
