摘　　要：目的:设计一种结构化电子病历的相似性查重方法,解决结构化电子病历中违规拷贝病历的质量控制问题。方法:定义结构化电子病历的文档模版查重属性、文档段查重属性,采用最小相似比字符串匹配(KMP)算法,实现相似病历查重,查找违规拷贝病历。结果:结构化电子病历的病历文档能够查找相似比大于某固定阀值的病历文档,进行违规拷贝病历的相似性查重,累计从3500余份病历中查重发现违规拷贝病历173份。结论:结构化电子病历的相似性查重方法可实现从患者的结构化电子病历文书中查找违规拷贝的病历,可有效控制医院病历质量。Objective: To design a method of similarity duplicate checking for structured electronic medical record so as to solve the problem of quality control of illegal copy in structured electronic medical records. Methods: To define the duplicate checking property of document template and document segment of structured electronic medical record, and adopt knuth-morris-pratt(KMP) of minimum ratio of similitude to achieve duplicate checking for similar medical record and look up medical records that were copy by using deregulation method. Results: It can find medical records with similar ratio greater than a fixed threshold from structured electronic medical records, and check the similarity of illegally copied medical records. A total of 173 copies of illegally copied medical records were found from more than 3500 medical records. Conclusion: The similarity duplicate checking method of structured electronic medical records can realize look up medical record that is copied by using deregulation from structured electronic medical record files, and can effectively control quality of medical records of hospital.
