Financial Toxicity in Neuromyelitis Optica Spectrum Disorder: An ABC‐X Mixed‐Methods Study

This study demonstrates substantial FT among NMOSD patients, influenced by clinical, psychological, and social factors. These findings highlight the importance of integrating FT assessment into routine clinical care. In the Chinese healthcare context, challenges including delayed diagnosis, restricted access to medication, and high costs contribute significantly to this burden. Policy-level interventions should focus on improving disease awareness, expanding treatment accessibility, and reducing financial strain on affected individuals and families.
