研究的目的是比较确定性记录链接算法和两个用于记录链接的公共领域软件应用程序(Link King和Link Plus)的准确性。这三种算法用于对包含超过500,000个客户的个人识别符的管理数据库进行重复数据删除。随后，随机抽样的相关记录被提交给四名研究人员进行盲目文书审查。以评价者的决定为‘金标准’，评估了敏感度和阳性预测值(PPV)。最理想的情况是，90年代中期的感光度和PPV都可以从Link King和Link Plus获得。使用基本确定性算法的灵敏度和PPV分别为79%和98%。因此，Link King的完整功能集使其成为SAS用户的一个有吸引力的选择。只要有必要的编程资源可用于处理Link Plus确定的记录对，Link Plus就是非SAS用户的理想选择。
The study objective was to compare the accuracy of a deterministic record linkage algorithm and two public domain software applications for record linkage (The Link King and Link Plus). The three algorithms were used to unduplicate an administrative database containing personal identifiers for over 500,000 clients. Subsequently, a random sample of linked records was submitted to four research staff for blinded clerical review. Using reviewers' decisions as the 'gold standard', sensitivity and positive predictive values (PPVs) were estimated. Optimally, sensitivity and PPVs in the mid 90s could be obtained from both The Link King and Link Plus. Sensitivity and PPVs using a basic deterministic algorithm were 79 and 98 per cent respectively. Thus the full feature set of The Link King makes it an attractive option for SAS users. Link Plus is a good choice for non-SAS users as long as necessary programming resources are available for processing record pairs identified by Link Plus.
