Increasing use of administrative records for research purposes has led to the need to develop methods for linking records. Linkage of the data from the Manitoba Health Services Commission (MHSC) with Canadian Vital Statistics records was done to verify Manitoba deaths, to measure degree of agreement between the two data sets, and to link "cause of death" information from Vital Statistics back to medical histories. A multi-stage approach to matching was adopted. Individual records matching perfectly across a number of relevant variables in the two files were selected first, reducing the number of records going through the probability matching to manageable proportions. Overall, almost 96% of the MHSC records were well matched with Vital Statistics records. Both uses of the matched data and various ways to confirm data quality are discussed.
出于研究目的，行政记录的使用日益增加，这就产生了开发记录链接方法的需求。将曼尼托巴省卫生服务委员会（MHSC）的数据与加拿大人口动态统计记录进行链接，以核实曼尼托巴省的死亡情况，衡量两个数据集之间的一致程度，并将人口动态统计中的“死因”信息与病史相链接。采用了多阶段匹配方法。首先选择在两个文件中的多个相关变量上完全匹配的个体记录，将进行概率匹配的记录数量减少到可管理的比例。总体而言，几乎96%的MHSC记录与人口动态统计记录匹配良好。文中讨论了匹配数据的两种用途以及确认数据质量的各种方法。
