目的量化5个不同医疗机构电子健康记录中标识符匹配记录的百分比，作为重复或潜在重复患者记录的指标，描述可能出现的患者安全问题，并提出管理重复记录或标识符匹配记录的解决方案。我们检索具有患者名和姓以及出生日期的精确匹配的记录的去识别计数，并确定存在于前250个最频繁出现的名和姓对的患者记录的数量。我们还确定了管理重复记录或记录匹配标识符的方法，报告每个跨institutions.Results的采用率匹配的第一个和最后一个名字在两个或两个以上的个人的发生率范围从16.49%到40.66%的记录，包括出生日期降低率范围从0.16%到15.47%。每个站点最常出现的名称的现有记录数量从41到2552不等。机构在他们实施的方法，以防止，检测和删除重复的记录，并减轻由此产生的errors.Conclusions记录匹配的患者标识符的百分比很高，在几个组织，表明重复的记录或记录的比率也可能很高。需要进一步努力改善重复记录或具有匹配标识符的记录的管理，并最大限度地降低患者伤害的风险。
Objective To quantify the percentage of records with matching identifiers as an indicator for duplicate or potentially duplicate patient records in electronic health records in five different healthcare organisations, describe the patient safety issues that may arise, and present solutions for managing duplicate records or records with matching identifiers.Methods For each institution, we retrieved deidentified counts of records with an exact match of patient first and last names and dates of birth and determined the number of patient records existing for the top 250 most frequently occurring first and last name pairs. We also identified methods for managing duplicate records or records with matching identifiers, reporting the adoption rate of each across institutions.Results The occurrence of matching first and last name in two or more individuals ranged from 16.49% to 40.66% of records; inclusion of date of birth reduced the rates to range from 0.16% to 15.47%. The number of records existing for the most frequently occurring name at each site ranged from 41 to 2552. Institutions varied widely in the methods they implemented for preventing, detecting and removing duplicate records, and mitigating resulting errors.Conclusions The percentage of records having matching patient identifiers is high in several organisations, indicating that the rate of duplicate records or records may also be high. Further efforts are necessary to improve management of duplicate records or records with matching identifiers and minimise the risk for patient harm.
