Given the increasing rates of labor induction and cesarean delivery, and efforts to reduce early term births, we examined recent trends in methods and timing of delivery.
We identified delivery methods and medical indications for delivery from administrative hospital discharge data for 231 691 deliveries in 2006 and 213 710 deliveries in 2010 from 47 specialty care member hospitals of the National Perinatal Information Center/Quality Analytic Services. In a subset of 17 hospitals, we examined trends by gestational age.
From 2006 to 2010, there was an 11% increase in labor induction and a 6% increase in cesarean delivery, largely due to repeat cesareans. There was a 4 per 100 reduction in early term births (37 to 38 weeks), mostly due to a decline in non-medically indicated interventional deliveries.
We report a shift in deliveries at 38 weeks, which we believe may be attributed to efforts to actively limit non-medically indicated early term deliveries.
鉴于引产和剖宫产率不断上升,以及努力减少早产的发生,我们研究了近期分娩方式和时机的变化趋势。
我们从全国围产期信息中心/质量分析服务的 47 家专业护理成员医院的行政出院数据中,确定了 2006 年的 231691 次分娩和 2010 年的 213710 次分娩的分娩方式和分娩医学指征。在 17 家医院的一个亚组中,我们根据胎龄检查了趋势。
2006 年至 2010 年,引产率增加了 11%,剖宫产率增加了 6%,这主要是由于重复剖宫产。早期分娩(37 至 38 周)减少了每 100 例 4 例,这主要是由于非医学指征的干预性分娩减少。
我们报告了 38 周分娩的变化,我们认为这可能归因于积极限制非医学指征的早期分娩的努力。
