Objective: To analyze the internal composition and changes of the hospitalization costs of lung cancer surgery patients, explore the main influencing factors of hospitalization costs, predict the trend of hospitalization costs, and provide an empirical basis for reducing the hospitalization medical burden of lung cancer patients. Methods: The information on the front pages of the hospitalization medical records of lung cancer surgery patients in a certain third-level Class-A hospital from 2018 to 2022 was collected. The new grey correlation and structural change degree analysis methods were used to study the internal structural changes of hospitalization costs and the correlation degree among them. Through univariate analysis and multiple linear regression analysis, the main influencing factors of hospitalization costs were explored. The GM(1,1) model was used to predict the hospitalization costs from 2023 to 2025. Results: (1) From 2018 to 2022, the average hospitalization cost per case of lung cancer surgery patients in this hospital decreased year by year, with an average annual decrease of 6.67%. (2) Drug costs, diagnostic costs, and surgical treatment costs were the main factors for the structural changes of hospitalization costs, with a cumulative structural change degree of 33.76% and a cumulative contribution rate of 86.23%. (3) The top three in the correlation degree ranking were material costs (0.952), comprehensive medical service costs (0.843), and diagnostic costs (0.697) in turn. (4) Multiple linear regression analysis showed that higher age, more number of complications/accompanying diseases, the medical payment method of urban employee basic medical insurance, and more hospitalization days were the influencing factors for the increase of hospitalization costs of lung cancer surgery patients (P < 0.05); the marital status of being widowed or divorced and emergency admission were the influencing factors for the decrease of hospitalization costs of lung cancer surgery patients (P < 0.05). (5) The GM(1,1) model predicted that the hospitalization costs would further decrease in the next three years. Conclusion: The control of hospitalization costs for lung cancer surgery in this hospital has achieved certain results, especially in controlling drug costs. The costs of surgical treatment that reflect the labor value of medical staff have increased. Diagnostic costs and material costs are the key points for the hospital to further control hospitalization costs in the next step. Clinically, the hospitalization costs of lung cancer surgery patients can be further reduced by early detection, early diagnosis, early treatment, and scientifically reducing the number of hospitalization days. Comprehensive measures should be taken to optimize the composition of patients' hospitalization costs, strengthen the management of controllable factors, and reduce the hospitalization medical burden of lung cancer surgery patients.
