Evaluation on ophthalmic service ability of county hospitals based on improved DS evidence theory / 中华医院管理杂志

ABSTRACT

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.
