It is important for pharmacists not only to improve medication adherence, but also to understand each patient's overall picture, including the patient's condition and living environment, in the context of multidisciplinary collaboration. In addition, pharmacists are required to link the appropriate use of medications with information obtained through physical assessments that appropriately utilize vital signs and clinical laboratory values. In this article, we introduce contents related to the “knowledge”, “skills”, and “attitude” required for certification as a pharmacist certified to support home care, as well as how to compile a case study of home care support for oneself. We hope that this will help many pharmacists to become certified.
