Identifying women at high risk of giving birth early would enable the health services to provide specialized care for these women to delay the birth or make sure they are in the best place to give birth (for example a hospital with a special care baby unit). Risk scoring systems have been suggested as a possible way of identifying these women. However, there is no research in this area so it is unclear whether the risk scoring systems would prolong pregnancy and reduce the numbers of preterm births or not.[29]
