摘　　要：研究试图使用在散点图中发现离群值的方法检测病案疾病分类的质量。若疾病分类错误,则可能产生离群值,反之,若产生离群值,则可能存在疾病分类错误。为验证此理论的有效性,随机抽取有手术和无手术的疾病的病案,分别是有手术的腹股沟疝,无手术的慢性阻塞性肺疾病。以住院费用为纵轴,住院天数为横轴,制作散点图。发现腹股沟疝病案的散点图中有两个离群值,结合病案分析,正确的主要诊断分别为弥漫性腹膜炎和腹股沟疝术后切口感染。慢性阻塞性肺疾病的散点图中也发现有离群值,分析显示其主要诊断也有误。散点图可用于提高疾病编码质量的工作。This paper attempts to detect the disease classification quality of medical records by discover the outlier with the application of scatter diagram. If the disease classification is error, it may bring the outliers, conversely, if the outliers exists, there may exists relevant disease classification error. In order to verify the validity of this theory, to extract the medical records with operation and non operation randomly, respectively, it is the operation of inguinal hernia, no operation for chronic obstructive pulmonary disease . Hospitalization expense is the vertical axis, and length of hospital stay is the horizontal axis, it makes the scatter diagram. Two outliers exist In the scatter diagram of inguinal hernia of the medical record, by analyzing the medical records, the correct main diagnosis is infection of incision wound diffuse peritonitis and inguinal hernia after surgery. Scatter diagram of the chronic obstructive pulmonary disease is also found to have outliers, and also there are mistakes in the primary diagnosis. Scatter diagram could be used to improve the quality of diseases coding work.
