Patient Access to Orphan Drugs Covered by Medical Insurance in China: Real-World Evidence From Patient Survey

After the inclusion of more high-cost orphan drugs in China's National Reimbursement Drugs List, this study investigated issues relating to patient access to the 7 medicines for 4 rare diseases after listing.This study collected data from a national survey conducted in China. Three aspects associated with the accessibility of medicines, namely, approachability, availability, and affordability, were analyzed using descriptive statistics. In addition, multilevel logistic regression models were used to investigate the associations between patient characteristics and the accessibility of surveyed orphan drugs.Of the 999 completed responses included in the study, 15% of the patients (n = 150) did not use the medicines because of non-medicine-related issues. Among the 849 patients using the surveyed medications, 64.4% (n = 547) encountered the problem of unavailability, whereas 51.2% (n = 435) reported affordability as an issue, and 49.6% (n = 320) had health expenditure beyond the catastrophic threshold. The data also indicated that Commercial Medical Insurance helped patients to relieve the cost burden on orphan drugs, but the payout of Commercial Medical Insurance failed to influence patients' decisions to continue the treatments.Accessibility of orphan drugs has improved in China after their inclusion in the National Reimbursement Drugs List. Nevertheless, the availability and affordability of medicines remained the barriers for patients to access the desired treatments. It is recommended that further policy refinement in conjunction with the collaboration among healthcare stakeholders is required to deliver better care for patients with rare disease.
