Assessment of Medical Expenditure for Patients With Breast Cancer in China: Evidence From Current Curative Expenditure by System of Health Accounts 2011

Objectives: The incidence and mortality of breast cancer have been increasing in China and bring heavy economic burdens to patients, families, and society. This study aimed to analyze the structure and influencing factors of inpatient expenditures of patients with breast cancer and put forward suggestions for insurance management. Methods: A multistage stratified random sampling method was used to investigate 379 medical institutions and 7366 pieces of inpatient records of patients with breast cancer in Dalian in 2018. Under the framework of "System of Health Accounts 2011," the current curative expenditure (CCE) and its distribution were calculated. The relationships between hospitalization expenditure and factors were analyzed by multiple stepwise regression and structural equation modeling. Results: The CCE of patients with breast cancer in Dalian in 2018 was U273.38 million, accounting for 10.66% of the total expenditure on cancer. The majority of the CCE flowed to large general hospitals. The CCE was concentrated in patients aged 40 to 69 years (23.46%). The hospitalization expenditure correlated positively with length of stay, surgery, and drug expenses (rs = 0.586-0.754, P < .01) and negatively associated with age (rs = 20.074, P < .01). The length of stay mediated the relationship between surgery and hospitalization expenses for patients with breast cancer. The factors that affected the hospitalization expenditure were the drug expenses, surgery, length of stay, insurance status, and institution level. Conclusions: The cost control for CCE of breast cancer inpatient treatment is crucial in China. Promoting hierarchical diagnosis and treatment, reducing the length of stay, and improving medical insurance depth would be effective measures to reduce the financial burden of patients.
