"Due to rising data collection costs and the availability of extant data files, record linkage is becoming increasingly important in evaluation research. We begin by discussing record linkage as a data-generating technique and its applicability to evaluation studies. This paper--part of a larger study assessing the perinatal outcomes of a comprehensive prenatal program for poor, urban women--describes a method for linking client records to live and stillbirth records [in Cleveland, Ohio]. Biases which can enter into the linkage process and general issues which need to be addressed early in an investigation are also discussed."
由于数据收集成本不断上升以及现有数据文件的可得性，记录链接在评估研究中变得越来越重要。我们首先将记录链接作为一种数据生成技术进行讨论，并探讨其在评估研究中的适用性。本文——一项评估针对贫困城市女性的综合产前项目围产期结局的大型研究的一部分——描述了一种将客户记录与[俄亥俄州克利夫兰市的]活产和死产记录相链接的方法。还讨论了可能进入链接过程的偏差以及在调查早期需要解决的一般问题。
