Evaluation of DRG Grouping Efficiency in Intensive Care Department based on Coefficient of Variation

Objective To evaluate the effectiveness of DRG grouping in Department of Critical Care Medicine,to find out existing problems,and provide suggestions for DRG payment or performance appraisal.Methods The DRG grouping was used to obtain the grouping results of discharged patients from the sample hospitals from 2016 to 2019.Among the 2555 discharged patients from the Department of Critical Care Medicine,the DRG group with the top 5 cases was selected as the DRG study group.All cases in the DRG study group were screened out of 351,148 discharged patients from the hospital.Patients in the same DRG group were divided into the whole hospital group(including patients discharged from the Department of Critical Care Medicine and non-critical medicine departments)and the Department of Critical Care Medicine group(including only patients discharged from the Department of Critical Care Medicine)according to the discharge department to which they belonged.The variable coefficient of hospitalization expenses was calculated to evaluate the intraclass homogeneity of the whole hospital group and the Department of Critical Care Medicine group.Results In the same DRG group,the variable coefficient of the hospitalization expenses of the discharged patients in the Department of Critical Care Medicine group was lower than that of the discharged patients in the whole hospital.That is to say,for the same DRG group,the intraclass homogeneity of hospitalization expenses in the group was higher when the patients discharged from the Department of Critical Care Medicine were evaluated separately.Conclusion When applying DRG payment or performance appraisal,for patients discharged from the Department of Critical Care Medicine,the DRG grouping should be refined or the group weight should be adjusted to form a more scientific and reasonable disease grouping.
