Abstract
ObjectiveTo evaluate the ophthalmic service ability of county hospitals in China based on the improved DS evidence theory.
MethodsConvenient 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.
ResultsThe 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.
ConclusionsOphthalmic service ability of county hospitals in China needs to be continuously improved. Improved DS evidence theory can be adopted to make continuous evaluation.
