Perspectives of Patients with Multiple Sclerosis on Drug Treatment: A Qualitative Study

Patients experience multiple sclerosis (MS) differently based on their disease type and other factors. This study aimed to explore the relative importance that patients with MS place on various attributes of MS drug therapies and to elucidate these patients' preferences regarding treatment characteristics such as administration, potential benefits, and side effects of the therapies.

Focus groups were conducted in Vancouver, Canada, with 23 adult patients with MS. Participants were interviewed in three groups based on disease category and MS treatment experience: treatment-naive, non-treatment-naive relapsing-remitting and non-treatment-naive progressive MS.

Overall, the most important characteristics of MS drugs were effectiveness and side effects. As such, there is hesitancy about trying new-to-market drugs because the risks, benefits, and costs may not be well known. Participants valued stability in their treatment and generally did not want to take on the additional risk of trying a new drug if they felt that their current medication was providing benefit. Convenience and method of administration were secondary considerations that would generally be valued only if expected risks and benefits were considered equal or superior.

This qualitative study shows that patients consider the impact and likelihood of benefits and side effects first and foremost when making drug treatment decisions and that other factors, such as convenience and method of administration, are of secondary concern.
