Abstract

Background Beers criteria have been into the mainstay to characterize the potentially inappropriate medication since its first publication, but the recent version, Beers 2019, is yet to be validated by clinical studies nationally. Objective To identify the prevalence and the predictors of potentially inappropriate medications in hospitalized geriatric patients based on the Beers 2019 and 2015 criteria. Setting Nanjing Drum Tower Hospital, a 3000-bed tertiary care teaching hospital in China. Method We conducted a cross-sectional study from July 1, 2018 to December 31, 2018. Data from all hospitalized patients aged ≥ 65 years were collected from the hospital database. Inappropriate prescriptions were identified using the Beers 2019 criteria and the Beers 2015 criteria. Main outcome measure Prevalence Ratio (PR) and predictors of potentially inappropriate medications. Results The prevalence of inappropriate prescriptions based on the Beers 2019 criteria was 64.80%. This result was slightly higher than that of the Beers 2015 criteria (64.31%). The most commonly encountered inappropriate prescriptions identified using the two criteria were proton-pump inhibitors. The kappa coefficient was 0.826 (p < 0.001) indicating a strong coherence between the two criteria. The most important factor associated with inappropriate medications use was the number of prescribed drugs (PR 5.17, 95% CI 2.89-8.43; PR 4.58, 95% CI 1.93-7.25). Conclusion This study showed a high prevalence of potentially inappropriate medication in the Chinese geriatric population, which was associated with the number of prescribed drugs. The predictors identified in this research might help pharmacists to detect high-risk drugs and intervene in time.
