Abstract：Objective To explore the structure and importance ranking of average hospitalization costs for patients with depression, and to provide a basis for improving the structure of patients′ hospitalization costs and effective cost control.Methods Information on the hospitalization costs of patients with depression in a tertiary hospital in Guangzhou City from 2018 to 2023 was collected, and the degree of association, composition ratio, and change of each cost with the average hospitalization costs per-time were evaluated by using the degree of structural variation and new gray correlation analysis.Results From 2018 to 2023, the average hospitalization cost per-time of patients with first gradually increased and then decreased, the proportion of diagnostic fee and examination fee continued to increase, and the proportion of nursing fee and drug fee continued to decrease. The degree of structural change of average hospitalization cost per-time during the 6-year period was 33.84%, and the degree of annual average structural change was 5.64%. The top 3 contributors to the structural change were drug fee (26.77%), diagnostic fee (23.43%) and medical service fee (19.77%), and the cumulative contribution of the three amounted to 69.97%. The results of the new gray correlation analysis showed that the treatment fee (0.939) had the greatest impact on the average hospitalization cost per-time of depressed patients, followed by the diagnostic fee (0.883), the examination fee (0.866) and the medical service fee (0.817).Conclusion Treatment fee, diagnostic fee and examination fee are the main factors affecting the hospitalization cost of depressed patients, and the income of nursing fee and drug fee continues to decrease. It is recommended to continuously optimize the cost structure and establish a reasonable, stable and efficient cost control program.
