A multicenter study to evaluate the disease burden and health economics of inpatients with multiple sclerosis in China.

OBJECTIVE:To assess the disease burden and health economics of inpatients with multiple sclerosis (MS) in China by evaluating the direct, indirect, and intangible costs. METHODS:A total of 863 patients were included for a cross-sectional retrospective study in 50 centers. The direct economic burden was measured by the cost of hospitalization and out-of-hospital application drugs, and the indirect economic burden was measured by the human capital method. The disability-adjusted life year (DALY) was used to express the intangible economic burden. Cost-utility analysis (CUA) using DALYs as indicators of health benefits was performed by calculating the incremental cost-utility ratio. RESULTS:The mean direct economic burden/year, daily medication expenses/year, DALY, indirect economic burden, and indirect economic burden/year were 27,655.57 Yuan, 17,944.97 Yuan, 10.89 Yuan, 512,041.7 Yuan, and 11,299.85 Yuan, respectively. For the study period of two years, the direct economic burden, daily medication expense, and indirect economic burden were 48.6%, 31.5%, and 19.85% of the total economic burden, respectively. Disease burden and the number of episodes of remission were not statistically significant (p>0.001). The direct economic burden and total economic burden of the disease-modifying therapy (DMT) group were higher than those of the non-DMT group, but DALYs had no statistical significance (p>0.001). CUA showed that inpatients with MS in the DMT group received a DALY every time compared with the non-DMT group. CONCLUSION:The DALY losses are concentrated in young and middle-aged Chinese people. In this two-year study, CUA prompted the application of DMT drugs to increase the economic burden and DALYs. However, follow-up time is still short, and further follow-up observation is required.
