Healthcare costs for patients with rare diseases: Evidence from China

Abstract

Objective: Rare diseases cause a huge financial burden to countless patients and families. It is an important public health issue that requires widespread attention. This study analyzes medical expenses composition and the change in trends of out-of-pocket (OOP) expenses for patients with Amyotrophic lateral sclerosis (ALS) and explores the factors influencing these changes.

Methods: Data were obtained from the Chinese Medical Insurance Department database from 2018 to 2020, including 857 patients with ALS in 60 cities across 30 provinces. We used descriptive methods to analyse the baseline characteristics and medical expenses of outpatients and inpatients with ALS. And we used quantile regression to analyse the differences in patient OOP ratio and the factors influencing them.

Results: In China, 80.3% of ALS patients chose tertiary hospitals, with an annual direct medical cost of 11,339.7 RMB per patient and an OOP ratio of 41.6%. The annual medical cost for outpatients was 345.1 RMB per patient, with an OOP ratio of 36.7%. The annual medical cost for inpatients was 28,139.8 RMB per patient, with an OOP ratio of 41.7%. Compared to outpatients, inpatients had higher medical costs but lower actual reimbursement rates. The OOP ratio of ALS patients decreased, then increased over time. And the OOP ratio was influenced by medical institution, medical insurance, and age (p < 0.05). Patients who chose tertiary hospitals, those who were covered by the urban resident basic medical insurance and younger patients had relatively higher OOP ratio.

Conclusion: In recent years, although China has begun to pay attention to the rights and interests of patients with rare diseases, the government has provided some healthcare security to patients with rare diseases. However, the level of medical insurance coverage was still low, the equity of protection was still insufficient and the financial burden on patients was high. Therefore, the government should further improve the healthcare system to provide full life-cycle and affordable healthcare services to patients with rare diseases.
