Nine Professional Standards Review Organizations jointly conducted an areawide medical care evaluation study of Cesarean births. Of 5,002 Cesarean births studied in 158 hospitals, only 1.1 per cent were judged to be unjustified procedures by local physician peer review. Although there was substantial geographic variation in rates of Cesarean birth (11.0%-18.3 per cent), no statistically significant pattern of variation was identified. Maternal outcomes and infant outcomes were generally good. This study demonstrates the potential for use of PSRO data in studying major issues in health care, as well as the practical constraints of such studies.
九个专业标准审查组织联合开展了一项关于剖宫产的区域医疗评估研究。在158家医院研究的5002例剖宫产中，当地医生同行评审判定只有1.1%为不合理手术。尽管剖宫产率存在显著的地域差异（11.0%-18.3%），但未发现具有统计学意义的变化模式。产妇和婴儿的结局总体良好。这项研究表明了利用专业标准审查组织（PSRO）数据研究医疗保健重大问题的潜力，以及此类研究的实际限制。
