"Medical teams"have been promoted in the home care setting. For the pharmacist, it is possible to maintain the safety and improve the quality of medical care by working with a multidisciplinary team. The arrangement of the pharmacist with the clinic is specified in Article 18 of the Medical Care Law, but there is no medical treatment fee for the clinic pharmacist. We examined the work content and usefulness of the clinic pharmacist. The work content was to participate in visiting consultation, introduce pharmacotherapy management based on the clinic pharmacist's working protocol, propose prescriptions, provide drug information service, and cooperate with insurance pharmacy pharmacists. Because the pharmacist was working in the clinic, he or she was able to actively intervene in drug treatment. Intervention in medication requires organizing and gathering information, which is difficult in the position of the insurance pharmacy pharmacist. The fact that the clinic pharmacist assumes this role and works with insurance pharmacy pharmacists makes it possible to maintain the safety and improve the quality of medical care.
