Three recent studies examined the national trend in labor induction in the United States. All show a doubling in the rate of induction during the 1990s, although vital statistics data show a consistently higher trend than that obtained from national hospital discharge data. Neither data source adequately documents the full range of indications for induction, its timing, hospital staffing considerations, and other factors that may play a role. Although rates of induction of labor may be leveling off, despite a lack of scientific evidence for its widespread use, rates are likely to remain at current levels for the next few years.
最近的三项研究调查了美国全国范围内引产的趋势。所有研究均表明，在20世纪90年代，引产率翻了一番，尽管人口动态统计数据显示的趋势一直高于从全国医院出院数据中得出的趋势。这两种数据来源都没有充分记录引产的全部指征范围、引产时间、医院人员配备考虑因素以及其他可能起作用的因素。尽管引产率可能正在趋于平稳，尽管缺乏广泛使用引产的科学证据，但在未来几年，引产率可能会维持在当前水平。
