Medical care measures of Japan strongly encourage a reduction of medical costs. In such a climate, hospitals encourage inpatients to return home as early as possible, thereby reducing the number of days in their hospital stay to reduce the medical cost. Consequently, the number of patients who receive home-care services has been increasing. Meanwhile, there are many areas that need to be improved for pharmacy to adequately support such advanced home-care services. For example, when a patient switches from inpatient-care to home-care, a pharmacy staff is suddenly asked to provide drugs or to have a home visit to take care the patient. In addition to that, the pharmacy will not receive the medical treatment information of the patient from the hospital. To improve such a case, we report our discussion based on how patient information should be provided to the pharmacy.
