The objective of the study was to propose a new measure of ideal childbirth outcome, based on the proportion of women delivering without maternal or newborn childbirth morbidity.
Using the 2002 California discharge dataset, we calculated rates of childbirth complications among women with singleton, term deliveries, stratified by pregnancy risk status, method of delivery, and parity. An ideal delivery (ID) was defined as a delivery without any complications. The distribution of hospital-level ID rates was calculated for laboring women stratified by parity.
Among 382,276 women, the ID rate was 78.5%. Rates, type, and severity of complications varied by risk group (high vs low risk), parity, delivery method, and across hospitals. Complications in childbirth were not rare; approximately 22% of deliveries had at least 1 complication. Women who delivered vaginally and multiparous women were more likely to have an ideal delivery.
The ID rate is a simple hospital-level measure of childbirth outcome that is easy to calculate and interpret.
本研究的目的是基于无孕产妇或新生儿分娩并发症的女性比例，提出一种衡量理想分娩结局的新方法。
利用2002年加利福尼亚出院数据集，我们计算了单胎足月分娩女性的分娩并发症发生率，并按妊娠风险状况、分娩方式和产次进行分层。理想分娩（ID）定义为无任何并发症的分娩。计算了按产次分层的临产女性医院层面ID率的分布情况。
在382,276名女性中，ID率为78.5%。并发症的发生率、类型和严重程度因风险组（高风险与低风险）、产次、分娩方式以及不同医院而有所不同。分娩并发症并不罕见；约22%的分娩至少有1种并发症。经阴道分娩的女性和经产妇更有可能实现理想分娩。
ID率是一种简单的医院层面分娩结局衡量指标，易于计算和解读。
