目的应用主成分分析法对某三甲医院2006年-2010年的医疗质量进行综合评价。方法采用文献分析法,选用代表性好的指标。数据来自北京市某三级甲等医院的统计报表,选择其中具有代表性指标18项,构建综合评价指标体系。然后通过主成分分析法对各指标排序,进行综合评价。结果从18项代表性指标中提取了三个公因子,前三个因子的特征值均大于1,且其累计贡献率为94.705%,远大于70%,故考虑取前3个因子。该医院2006年-2010年综合得分分别为-0.52、-0.45、0.13、0.37、0.45。其得分与医院实际情况相符合,反映医院医疗质量呈逐年上升趋势。结论本文运用主成分分析法对医院的医疗指标进行了综合评价,主成分分析法能够客观、全面地反映医院各项指标的变化。可以为医院管理者提供科学管理的依据和参考。
Objective To evaluate the medical quality of a top-three hospital from 2006 to 2010 by using principal component analysis. Methods using literature analysis, the selection of good indicators. The data come from the statistical reports of a tertiary level hospital in Beijing and selected 18 representative indexes to construct a comprehensive evaluation index system. Then through the principal component analysis of the indicators of the sort, a comprehensive evaluation. Results Three common factors were extracted from 18 representative indexes. The first three factors all had eigenvalues greater than 1, and their cumulative contribution rate was 94.705%, much higher than 70%. Therefore, the first three factors were taken into consideration. The hospital from 2006 to 2010 comprehensive score was -0.52, -0.45,0.13,0.37,0.45. The score is consistent with the actual situation in the hospital, reflecting the rising trend of the medical quality of the hospital year by year. Conclusion In this paper, principal component analysis is used to comprehensively evaluate the hospital’s medical indicators. The principal component analysis method can objectively and comprehensively reflect the changes of various indicators in the hospital. Hospital administrators can provide the basis for scientific management and reference.
