目的：为了确定记录匹配的准确性，使用“Link King”软件，使用一个有序的分数的确定性，链接的记录是有效的matches.Methods：我们链接的记录在北卡罗来纳州医疗补助文件的公共卫生监督文件，使用Link King匹配软件。我们从45，295份关联记录中选择了230份分层随机样本，从35，119份非关联监督记录中选择了50份，然后手动审查了这些记录。以人工回顾为金标准，根据LinkKing评分的每个临界点计算敏感性（Sn）和特异性（Sp）。（95% CI：0.785，0.892）降至0.935（0.879，0.994），Sp从0.893（0.816，0.976）降至0.865（0.790，0.947），因为改变了临界点以扩大声明匹配的范围。与Sn和SP的目标是大，准确性是最好的，当连接记录对从前三个级别的确定性包括在match.Conclusions：这项研究发现，一个公开的软件程序准确地合并医疗补助和监测数据。LinkKing可以帮助研究人员合并管理数据库。
Objective:To determine the accuracy of record matching using “Link King” software that uses an ordinal score for the certainty that linked records are valid matches.Methods:We linked records in North Carolina Medicaid files to public health surveillance files using Link King matching software. We selected a stratified random sample of 230 of 45,295 linked records and 50 of 35,119 non‐linked surveillance records, then manually reviewed the records. Sensitivity (Sn) and Specificity (Sp) were calculated based on each cut point of the Link King score, using manual review as the gold standard.Results:The Sn increased from 0.837 (95% CI: 0.785, 0.892) to 0.935 (0.879, 0.994) and Sp decreased from 0.893 (0.816, 0.976) to 0.865 (0.790, 0.947) as cut points were varied to widen the scope of declared matches. With a goal of both Sn and Sp being large, accuracy was best when linked record pairs from the top three levels of certainty were included in the match.Conclusions:This study found that a publicly available software program accurately merged Medicaid and surveillance data. The Link King could be useful to researchers in merging administrative databases.
