This paper provides a detailed description of a method developed for purposes of linking records of individual patients, represented in diverse data sets, across time and geography.
The procedure for record linkage has three major components-data standardization, weight estimation, and matching. The proposed method was designed to incorporate a combination of exact and probabilistic matching techniques.
The procedure was validated using convergent, divergent, and criterion validity measures.
The output of the process achieved a sensitivity of 92 percent and a specificity that approached 100 percent.
The procedure is a first step in addressing the current trend toward larger and more complex databases.
本文详细描述了一种为跨时间和地域链接以不同数据集呈现的个体患者记录而开发的方法。
记录链接程序有三个主要组成部分——数据标准化、权重估计和匹配。所提出的方法旨在结合精确匹配和概率匹配技术。
使用收敛效度、区分效度和标准效度测量方法对该程序进行验证。
该过程的输出灵敏度达到92%，特异性接近100%。
该程序是应对当前数据库日益庞大和复杂这一趋势的第一步。
