【摘要】 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。更多还原

【Abstract】 Objective To establish DRGs based on data from the first pages of inpatient records in the hospitals of Zhejiang and covering common disease categories. Methods A case mix study was made on the inpatients in Zhejiang using AID and a prospective plan was evaluated with RIV values,the coefficients of variance, the non-parametric test, and the back substitution test. Results 19 major diagnosis categories and 53 subcategories were established according to ICD-10 and 266 case mixes were identified. The RIV values averaged 0. 2573 and the coefficients of variance averaged 87. 70%. The P values of all the case mixes, analyzed with the Kruskal-Wallis test, were < 0. 0001 and the results of the back substitution test were good, which showed that the case mix plan was rational. Conclusion It is reasonable to use AID to study case mixes and to establish DRGs of inpatients in Zhejiang that cover common disease categories and contain 266 case mixes.更多还原
