In recent years, there have been many reports on how polypharmacy is addressed in hospitals through multidisciplinary collaboration; however, there are few reports on how pharmacies are addressing polypharmacy among outpatients in collaboration with physicians and hospital pharmacists. In September 2020, physicians, hospital pharmacists, and pharmacy pharmacists collaborated to establish a model for dealing with polypharmacy in community pharmacies (creating a polypharmacy assessment tool and conducting regular joint conferences between hospitals and pharmacies). In this study, the actual state of polypharmacy intervention by pharmacy pharmacists after the introduction of this model was investigated. The study was conducted at three community pharmacies over a 6-month period. A tool-based polypharmacy assessment of patients aged 65 years or older taking six or more prescription drugs revealed that 97% (65/67 patients) experienced polypharmacy issues and in 44.8% (30/67 patients), the pharmacist considered it necessary to report the patient’s condition to the physician. Of the 35 informational letters reported to physicians, 28 were prescription suggestions, with a prescription change rate of 46.4% (13/28). The improvement rate of adverse drug events after pharmacist intervention was 54.0% (27/50), and the improvement rate of adherence was 66.7% (24/36). These results indicate that the model for dealing with polypharmacy in community pharmacies contributed to the improved ability of pharmacy pharmacists to intervene, because of the establishment of criteria for evaluating polypharmacy and because hospital-pharmacy joint conferences, which are key to community collaboration, were continuously held.
