Abstract Objective To explore the relative weight setting of diagnosis related groups. Methods Based on the five categories of cost composition of the cost of hospitalization, through three methods to determine the proportion of various types of costs, and calculated the each DRG group relative weight on Peking University Shenzhen Hospital through the CN-DRGs (2016 version). Results The number of cases admitted to the study in the hospital in 2016 was 57719. The DRG group distribution, total weight, CMI was not very different among the three methods of calculation results. The total weight and CMI was respectively 57523.54, 57538.42, 56955.98 and 0.9966, 0.9969, 0.9868. Conclusion To apply DRGs for the performance evaluation of capacity dimension, the relative weight of each DRG group should be further studied in combination with clinical experience and statistical method.
