Abstract: This paper uses the data collected from 138,477 patient discharge records of 37 Shanghai tertiary public hospitals in December 2013 and classifies all the records into different groups by using a localized diagnosis re-lated group tool.The coefficient of variation index ( CV) of each group was used to analyze the dispersion of average hospital cost per inpatient day for each group, in order to evaluate the suitability of diagnosis related group systems and to set the coefficients of difficulty ( relative weights) for each disease.The study has found that severity-based di-agnosis related group systems are more suitable and consistent.However, future studies should collect more detailed information on health costs in order to reflect the value of health professionals and technologies and therefore further improve diagnosis related classification and develop new systems that can be adapted to local conditions by applying the weights of different groups.
