Focusing on the Pharmaceutical Intervention Records (PIR) project conducted in collaboration with the Gifu Pharmaceutical Association and Gifu Pharmaceutical University, this study analyzed characteristics and economic effects of the audit of dispensing fees for the prevention of duplications or interactions of prescription drugs by pharmacists. The pharmacists registered audit data of 1,105 prescriptions into the PIR database in 2017. For the analysis, we divided 1,105 prescriptions into those that incurred dispensing fees for the prevention of duplications or interactions of prescription drugs (the subject group) and a control group comprising other prescriptions. The reduction in drug cost per prescription was 1,689 yen in the subject group, which was significantly higher than the reduction of 563 yen in the control group. In the subject group, pharmacists tend to use a medicine notebook for identifying duplicate administrations or drug interactions. There is a high ratio of cancellation of drugs as a result of such inquiries. This is considered a factor in the reduction of the cost of drugs. The reduction per prescription in the subject group is higher than the medical fees for the prevention of duplications or interactions of prescription drugs, and it can be evaluated that activities related to preventing duplications and interactions of prescription drugs contribute to medical economy.
