目的：了解产妇护理的模式需要知道哪些妇女以前生过孩子，但这些信息通常在行政医院的数据集中是不可用的。研究设计和背景：使用医院事件统计数据，我们确定了英国国家卫生服务医院在2009年4月至2010年3月期间分娩的妇女的记录。将这些记录中编码的胎次与2000年4月至2009年3月以前住院分娩中确定的分娩估计值进行比较。结果：我们在2009-10年的出生记录中确定了358,849例符合条件的分娩，并具有完整的胎次数据。历史数据将168,041名妇女归类为经产；其中98%的人在出生记录中被编码为经产。在190,798名使用历史数据被归类为初产的妇女中，72%的人在她们的出生记录中被编码为初产。历史资料对初产状况的预测准确率随年龄的变化而变化，15-18岁的女性为，35岁以上的女性为50%。结论：行政医院数据集中的历史记录可以准确地提供有关女性经产状况的信息。对初产状况有一些错误的分类，不同的妇女亚群的错误率也不同。(C)2014 Elsevier Inc.保留所有权利。
Objectives: Understanding patterns of maternity care requires knowing which women have given birth previously, but this information is typically unavailable in administrative hospital data sets. We assessed how well parity can be derived using linked historical records.Study Design and Setting: Using Hospital Episode Statistics data, we identified records of women who gave birth between April 2009 and March 2010 in English National Health Service hospitals. The parity coded in these records was compared with an estimate derived from deliveries identified in previous hospital admissions between April 2000 and March 2009.Results: We identified 358,849 eligible deliveries with complete parity data in the 2009-10 birth records. The historical data classified 168,041 women as multiparous; of whom, 98% were coded as multiparous in their birth record. Among 190,798 women classified as primiparous using historical data, 72% were coded as primiparous in their birth record. The proportion of accurate predictions about primiparous status from historical data varied with age, ranging from 89% for 15-18 year olds to 50% for women aged more than 35 years.Conclusion: Historical records in administrative hospital data sets give accurate information on multiparous status of women. There is some misclassification of primiparous status, and error rates differ among subgroups of women. (C) 2014 Elsevier Inc. All rights reserved.
