Abstract:

Objective: To study the economic burden of Crohn’s disease and its related factors, and to provide opinions for reducing personal burden and improving reimbursement policy. Methods: Using a cross-sectional method, a self-created questionnaire based on the basic principles of health services research was used to survey Crohn’s disease patients served by the Shanghai volunteer service foundation platform. Information collected included basic characteristics, therapy, and medical costs related to Crohn’s disease in the past 12 months. Descriptive statistics were used to analyse the composition of inpatient and outpatient costs of Crohn’s disease for treatment of the disease in the past year. Further, a logarithm-linear model was constructed to analyse the factors associated with the financial burden of Crohn’s disease. Results: In the study, 820 questionnaires were distributed and 799 questionnaires were returned, of which 797 were valid. There were 528 (66.25%) males and 269 (33.75%) females. The mean age of the patients was (34.02±11.49) years, with a concentration between 18-39 years (510 cases, 63.99%) and a mean disease duration of (5.58±5.13) years. 10.7% of the patients did not receive continuous treatment, and the average annual treatment cost for the patients with continuous treatment was 54 246 Yuan, of which 30 279 Yuan (55.8%) was paid by the individuals and 23 966 Yuan (44.2%) was paid by the insurance. The personal financial burden was close to the national per capita disposable income in 2020, which was 32 189 Yuan (94.1%), exceeding the annual cost for type 2 diabetes in China in 2016, 8 245 Yuan. In terms of the distribution of outpatient and inpatient services, the average annual cost of inpatient services was 31 092 Yuan, of which 14 673 Yuan (48.5%) was paid out of pocket by the individuals and 16 418 Yuan (51.5%) was paid by the insurance; the average annual cost of outpatient services was 23 154 Yuan, of which 15 606 Yuan (65.1%) was paid out of po-cket by the individuals and 7 548 Yuan (34.9%) was paid by the insurance. The personal burden of outpatient care was higher than of inpatient care. The regression results of the logarithm-linear model showed that the total annual treatment cost was related to the duration of illness (β=0.03, P<0.01), having complications (β=-0.68, P<0.01), receiving surgical treatment (β=0.52, P<0.01), using immunosuppressive drugs (β=0.51, P<0.01), annual outpatient visits (β=0.02, P<0.05), and number of hospitalizations per year (β=0.08, P<0.01). Conclusion: The annual financial burden for patients with Crohn’s disease is heavy and rises significantly with the duration of illness, exceeding that of chronic diseases such as diabetes. The personal financial burden is close to the national per capita disposable income, and the medical security department should develop policies to reduce the financial burden. The inclusion of Crohn’s disease as a special outpatient disease is a possible measure that could be considered in response to the fact that the outpatient personal financial burden is heavier than the inpatient’s.
