作者对早产风险评分系统（RPD）的价值进行了前瞻性分析。RPD系统预测大约10%的患者将有早产和分娩。虽然这些患者中只有三分之一在足月前分娩，但他们约占所有早产的三分之二。RPD系统对多胎妊娠的判别效果优于单胎妊娠，在孕26 ~ 28周再评分可提高预测的准确性。
The authors performed a prospective analysis of the value of a system for scoring the risk of preterm delivery (RPD). The RPD system predicts that approximately 10% of patients will have preterm labor and delivery. Although only one third of these patients deliver before term, they account for approximately two thirds of all preterm births. The discrimination of the RPD system is better for multi-gravid patients than for primigravid patients, and rescoring at 26 to 28 weeks' gestation improves the accuracy of prediction.
