目的分析医疗质量指标的潜在影响因素,综合评价医疗质量,探寻不同阶段医疗质量的变化情况。方法用因子分析法统计山东大学附属省立医院2007年1月至2008年12月的14项医疗指标,包括总诊疗人次、出院人次、手术台次、床位使用率、床位周转次数、平均住院日、治愈好转率、病死率、入院与出院诊断符合率、病理与临床诊断符合率、手术前后诊断符合率、院内感染率、平均住院费用、无菌手术甲级愈合率,使用SPSS16.0软件进行统计学处理。结果从14项指标中提取出3个公因子,第一公因子为医疗数质量因子;第二公因子为医疗水平因子;第三公因子为医疗感染因子。3个公因子的累积方差贡献率达75.04%;2年间总因子得分同期相比均上升。结论医疗数质量因子、医疗水平因子和医疗感染因子是医疗质量指标的主要影响因素,因子得分可以为医疗质量综合评价提供指导建议。
Objective To analyze the potential influencing factors of medical quality indicators, comprehensively evaluate the quality of medical care and explore the changes of medical quality at different stages. Methods A total of 14 medical indicators from January 2007 to December 2008 of Provincial Hospital Affiliated to Shandong University were calculated by factor analysis, including total number of patients, number of discharge, operation table, bed occupancy rate, number of bed turnover, average length of stay , Cure improvement rate, case fatality rate, the coincidence rate of hospital admission and discharge diagnosis, coincidence rate of pathology and clinical diagnosis, preoperative and postoperative diagnosis coincidence rate, nosocomial infection rate, average hospitalization costs, aseptic surgery grade A healing rate, using SPSS16.0 software Statistical analysis. Results Three common factors were extracted from 14 indexes, the first common factor was the medical quality factor, the second common factor was the medical level factor, and the third common factor was the medical infection factor. The cumulative variance contribution rate of three common factors reached 75.04%, while the total factor score increased over the same period in two years. Conclusion The quality of medical factors, medical factors and medical infection factors are the main influencing factors of medical quality indicators. The score of factors can provide guidance for the comprehensive evaluation of medical quality.
