Background: The American Geriatric Society have announced the 2012 updated version of Beers criteria intended to improve care of older adults by reducing their exposure to potentially inappropriate medications (PIMs). However, there have been no reports on prevalence of PIMs prescription by the 2012 version of Beers criteria in South Korea.
Methods: This is a retrospective study using medical records and code analysis of each PIM to survey the prevalence of PIMs prescription and common PIMs used for elderly patients. Finding all kinds of PIMs was carried out in all outpatients who had visited Asan Medical Center from May 2012 to April 2013. Selection of PIMs was totally based on the 2012 updated version of Beers criteria.
Results: A total of 652,192 outpatients aged over 65 years, who visited our medical center for study period, were analyzed. Among them, 33,810 (5.19%) of the elderly patients received at least one PIM, and 125,498 cases of PIM prescription were occurred during study period. The percentage of the patients who received at least two kinds of PIMs concurrently was 33.14%. Common PIMs were tramadol (24.15%), clonazepam (11.51%), ibuprofen (10.02%), megesterol (9.80%), and amitriptyline (9.51%).
Conclusion: Our study shows the prevalence of PIMs prescription for Korean elderly outpatients in single tertiary medical center. Compared with previous reports using old version of Beers criteria, there was a change in priority of common PIMs in our study.
