Abstract
This study examined the economic efficiency of the separation of prescription and dispensation medicines between doctors in medical institutions and pharmacists in pharmacies. The separation system in Japanese prefectures was examined with publicly available data (Ministry of Health, Labour and Welfare, 2012–2014; retrieved from http://www.mhlw.go.jp/topics/medias/year). We investigated whether the separation system reduces the number of medicines or the medication cost of a prescription because of separating the economic management between prescribing and dispensing and the effect of mutual observation between doctors and pharmacists. It is optional for Japanese medical institutions to participate in the separation system. Consequently, the spreading rate of the separation system in each administrative district is highly variable. We examined the separation system effect using the National Healthcare Insurance data for three years, 2012–2014. We tested whether the separation system ratio for each prefecture was significantly correlated to the medication price or the number of medicines on a prescription. If spreading the separation system influenced the price of prescribed daily medications or the number of medicines, the correlation would be significant. As a result, the medication price was significantly negatively correlated with the separation system ratio, but the number of medicines was not significant. Therefore, the separation system was effective in reducing daily medication cost but had little influence on reducing the number of daily medicines. This was observed over three years in Japan.
