Objective To investigate potentially inappropriate medication used among the hospitalized elderly patients in Tianjin Medical University General Hospital, and analyze the related influencing factors. Methods A total of 1 800 patients over 65 years old in Tianjin Medical University General Hospital from January to June in 2017 were chosen. Their potentially inappropriate medications were evaluated according the Beers criteria (2015 version). Chi-square test and multivariate logistic regression analysis was conducted to reveal the related influencing factors of potentially inappropriate medication. Results According to the Beers criteria, 614 patients (34.11%) got 955 potentially inappropriate medications. Factors associated with greater likelihood of potentially inappropriate medication prescribing were the number of drugs and the illnesses. Conclusion Beers criteria is a well-established method for evaluating potentially inappropriate medication of elderly patients. In order to improve rational drug use and guarantee the drug safety, We should controlled the related influencing factors of potentially inappropriate medication in clinical treatment.
