Abstract

Objective: South Korea made a list of inappropriate medications for elderly patients in 2015 and have induced medical team to use proper medication by using drug utilization review (DUR) system. It's been three years since the system was introduced, but related studies have rarely been conducted. The aim of this study is to evaluate the DUR system on potentially inappropriate medications for elderly patients. Methods: The data of inappropriate medications for elderly patients(≥65 years) who received medical treatment between March 1st and May 31st in 2015 (before applying DUR) and who received medical treatment between March 1st and May 31st in 2018 (after applying DUR) were retrospectively collected from electronic medical record. Results: The prescriptions of inappropriate medications decreased from 3,716(7.7%) to 3,857(6.9%). The most frequently prescribed medications were amitriptyline (before DUR 43.8%, after DUR 35.5%) and clonazepam (before DUR 38.0%, after DUR 45.6%). Conclusion: Inappropriate medications of elderly patients were significantly decreased(Ρ<0.001) after DUR was introduced. And the wider information of inappropriate medications are needed to be offered in various ways.
