Structural analysis of hospitalization expenses of patients with mental disorder based on new gray relational and structural variation degree

Objective To investigate the composition and variation trend of hospitalization expenses of mental disorder inpatients in a psychiatric hospital in Shenzhen from 2013 to 2017, to explore the main factors affecting the hospitalization expense structure, and to determine its change direction.Methods In this study, a database was established based on hospitalization expense information of discharged mental disorder patients from a psychiatric hospital in Shenzhen from 2013 to 2017. The new gray relational analysis method was used to analyze the relationship between the single item cost and the total cost, then the structural variation degree method was used to analyze the structural changes of hospitalization expenses during the five years.Results From 2013 to 2017, the per capita total hospitalization expenses of mental disorder inpatients increased by 4 603.95 RMB, with an average annual growth rate of 9.37%. The cost of comprehensive medical service had the biggest impact on the total cost, followed by the diagnosis cost and treatment cost. The five-year change of hospitalization expenditure structure was 76.06%, and the average annual change was 19.02%. The main items affecting the structural change of hospitalization expenses included treatment, comprehensive medical services and diagnosis. The cumulative contribution rate of these three items was 93.13%.Conclusion The main items of the total cost are transformed from the treatment category to the comprehensive medical service category. The application of new gray relational analysis and structural variation analysis method plays a vital role in the analysis of hospitalization expenses of patients with mental disorders.
