Medical teams have been promoted in home care. It is possible for pharmacists who are part of a multidisciplinary team to maintain safety and improve the quality of medical care. Protocol-based pharmacotherapy management(PBPM)is recommended for cooperation between the pharmacist and the doctor in the management of pharmacotherapy. In order to introduce PBPM, it is necessary for the pharmacist and the doctor to cooperate and to extract the problems in community medicine. In this study, the clinic pharmacist examined the problem of unnecessary inquiries and proposed PBPM. He suggested that to smoothly introduce PBPM, a protocol creation committee should be set up and an explanation of PBPM should be provided to the Community Pharmacist Association. As a pilot study, we created 5 protocols at Doctor GON Kamakura Clinic with the cooperation of 8 pharmacies. As a result, it became possible to reduce unnecessary inquiries by 46%. Careful coordination is necessary in order to introduce PBPM at clinics and community pharmacies. Moreover, a clinic pharmacist is able to facilitate the introduction of PBPM in the role of coordinator.
