目的建立基于浙江省医院病案首页信息且覆盖常见病种的疾病诊断相关组(diagnosisrelated groups,DRGs)。方法应用自动交互检测方法(automatic interaction detector,AID),对浙江省住院病人进行病例组合研究,用RIV(reduction in variance)值、变异系数、非参数检验和回代检验对建立的方案进行评价。结果根据ICD-10建立19个主要诊断类目及53个细类,分析后共得266个病例组合。RIV值平均值为0．2573,变异系数平均值为87．70％,所有组合经Kruskal-Wallis检验,P值均< 0．0001,且回代检验效果较好,均说明病例组合方案合理。结论应用AID方法研究病例组合,对浙江省住院病人建立覆盖常见病种的包含266个组合的DRGs是合理的。
Objective To establish diagnosisrelated groups (DRGs) based on the first page of medical records in Zhejiang Province and cover common diseases. Methods By using automatic interaction detector (AID), the case study of inpatients in Zhejiang Province was carried out. The reduction in variance (VIV), coefficient of variation (CV), nonparametric test and back-test were used to evaluate the scheme. Results According to ICD-10, 19 main diagnostic categories and 53 sub-categories were established. A total of 266 case combinations were analyzed. The average RIV value was 0.2573 and the average coefficient of variation was 87.70%. All the combinations were all tested by Kruskal-Wallis test, P <0.0001. Conclusion It is reasonable to use AID method to study combination of cases and to establish 266 inpatient DRGs covering common diseases in Zhejiang Province.
