Methods: A retrospective, cross-sectional study was conducted among geriatric patients at Beijing Chao-Yang Hospital between January 2018 and March 2018. Three criteria (the Beers criteria of 2015, the STOPP criteria of 2014 and the Chinese criteria) were used to detect PIMs. A multivariate logistic regression analysis was carried out to determine factors associated with the use of PIMs. Leading PIMs for each set of criteria were also listed. The concordance among the three PIM criteria was calculated using kappa tests. Results: Totally, 863 inpatients aged ≥65 years were included. The prevalence of patients receiving at least one PIM was 80.2%, 58.1% and 44.0% according to the Chinese criteria, 2015 Beers criteria and 2014 STOPP criteria, respectively. The Beers and the STOPP criteria indicated a moderate coherence, whereas the Chinese criteria showed poor concordance with the other two criteria. Proton-pump inhibitors in the Beers and STOPP criteria and clopidogrel in the PIM-Chinese accounted for most leading PIMs. The most important factor associated with PIM use by all three sets of criteria was the number of prescribed medications. Conclusion: Data showed a high PIM prevalence among older adults in China, which was associated with the number of prescribed medications. The Chinese criteria had the highest detection rate but a poor concordance with the Beers and STOPP criteria (P<0.001).
