Evaluation of Potentially Inappropriate Medication in Elderly Hospitalized Patients in Our Hospital Based on 2019 Beers Criteria / 中国药学杂志

ABSTRACT

OBJECTIVE: To investigate and analyze the potential inappropriate medication(PIM) in elderly hospitalized patients in our hospital, explore the related risk factors, and analyze the use of PIM involved drugs in different departments, so as to provide reference for the formulation of medication manuals for the elderies in different departments and for further standardizing the use of drugs in elderly patients. METHODS: The medical advice for elder patients(≥65 years old)hospitalised from January to October 2017 in our hospital was collected. Beers criteria of American Geriatrics Association 2019 was used as the reference to investigate and analyze PIM. And the risk factors of PIM were analyzed by logistic regression. RESULTS: The average age of 12 756 elderly hospitalized patients was (74.13±6.88) years and the average number of diseases per patient was (3.22±2.09). For each patient, (4.79±3.76) kinds of medicines were used. According to the 2019 Beers criteria, the incidence of PIM was 20.00%. Among them, the central nervous system medications(6.41%, 818/12 756) (estazolam tablets, alprazolam tablets) were the most frequently used. Data of PIM occurrence in different departments showed that the PIM incidence was higher in rheumatology, geriatrics, rehabilitation, anesthesia surgery and oncology departments. In addition, logistic regression analysis showed that gender, age, the number of combined medications and diseases, and length of stay were all potential risk factors for PIM. CONCLUSION: The incidence of PIM in elderly hospitalized patients in our hospital is high. The rational drug use in elderly patients needs to be improved.
