基于改进DS证据理论评价县级医院眼科服务能力

Evaluation on ophthalmic service ability of county hospitals based on improved DS evidence theory

目的:基于改进DS证据理论,对我国县级医院眼科服务能力进行评价。方法:以方便抽样方法,选取我国东、中、西部9家县级医院眼科的2019年数据,应用基于马氏距离权系数的改进DS证据理论方法开展医疗服务能力评价,并与经典证据理论方法的评价结果进行比对分析。结果:我国县域眼科服务能力区域性发展不均衡,部分指标的评价结果存在地区差异性,东部地区医院在医疗服务量相关的多项指标评价上总体领先,东部地区医院住院手术量、门诊手术量、床位周转次数、床位使用率、住院人次、门诊人次、急诊人次等指标均值分别为西部地区医院均值的3.25、1.60、1.81、1.61、2.64、2.63、4.47倍。与经典证据理论方法相比,改进DS证据理论方法分析结果与各医院实际业务发展情况一致,评估结果可信,能更有效降低评估结果中的不确定性。结论:我国县级医院眼科服务能力仍有待持续提升,有必要应用改进DS证据理论方法开展持续评价。

Objective To evaluate the ophthalmic service ability of county hospitals in China based on the improved DS evidence theory.Methods Convenient sampling method was used to select the data of ophthalmology department of 9 county hospitals in eastern,central and Western China in 2019.The improved DS evidence theory method based on Mahalanobis distance weight coefficient was applied to evaluate the medical service ability,and the evaluation results were compared with the classical evidence theory method.Results The regional development of ophthalmic service capacity in counties of China was uneven,and there were regional differences in the evaluation results of some indicators.Hospitals in the eastern region were generally leading in the evaluation of a number of indicators related to the amount of medical services.The numbers of inpatient operations,outpatient operations,bed turnover times,bed utilization rate,number of inpatients,number of outpatients,number of patients in the eastern region were 3.25,1.60,1.81,1.61,2.64,2.63 and 4.47 times of the numbers of hospitals in western region.Compared with the classical evidence theory method,the analysis results of the improved DS evidence theory method were consistent with the actual business development of each hospital,and the evaluation results were credible,which could more effectively reduce the uncertainty in the evaluation results.Conclusions Ophthalmic service ability of county hospitals in China needs to be continuously improved.Improved DS evidence theory can be adopted to make continuous evaluation.
