Home parenteral nutrition (HPN) is a useful measure when cancer patients are hoping to have a transition from the hospital to a home medical care arrangement. A contribution of pharmacist performing HPN to a patient is to manage pharmaceuticals so that an appropriate medicine is used for not only the prescription design of the infusion solution but also to give a relaxation care. Based on the patient information record gathered by a home-visit nursing care program, we tried to study what pharmacists could do to help the patient after he was discharged.
