The annual number of births in our region is about 5,000, and most of the deliveries occur in three hospitals and six clinics. As the numbers of childbirth facilities in our region has declined, since 2006 we have attempted to achieve a division of roles according to the functions of childbirth facilities in order to prevent the collapse of regional perinatal care services. A multicenter study has been conducted to evaluate the Japanese pregnancy risk score as a means of objectively evaluating how far centralization of high-risk pregnancies to regional perinatal centers and decentralization of low-risk pregnancies to regional medical institutions have progressed. Although the number of low-risk pregnancies in a regional prenatal center decreased from 305 cases per year in 2006 to 164 cases per year in 2010, the number of high-risk pregnancies in a regional perinatal center increased from 255 cases per year in 2006 to 372 cases per year in 2010. The data showed that centralization of high-risk pregnancies to a regional perinatal center and decentralization of low-risk pregnancies to regional medical institutions had been achieved in our region.
