| Sumario: | Objective: To assess patients' preferences for a range of disease-modifying therapy (DMT) attributes in multiple sclerosis (MS). Design: A cross-sectional observational study. Setting: The data reported were from 17 MS units throughout Spain. Participants: Adult patients with relapsing-remitting MS. Main outcome: A conjoint analysis was applied to assess preferences. A total of 221 patients completed a survey with 10 hypothetical DMT profiles developed using an orthogonal design and rating preferences from 1 (most acceptable) to 10 (least acceptable). Medication attributes included preventing relapse, preventing disease progression, side effect risk, route and frequency of administration. Results: Patients placed the greatest relative importance on the side effect risk domain (32.9%), followed by route of administration (26.1%), frequency of administration (22.7%), prevention of disease progression (10.0%) and prevention of relapse (8.3%). These results were independent of the Expanded Disability Status Scale score. The importance assigned to side effect risk was highest for patients with a recent diagnosis. Patients who had previously received more than one DMT gave a higher importance to relapse rate reduction than patients receiving their first DMT. Conclusions: Patient DMT preferences were mainly driven by risk minimisation, route of administration and treatment schedule. The risk-benefit spectrum of available DMT for MS is becoming increasingly complicated. Understanding which treatment characteristics are meaningful to patients may help to tailor information for them and facilitate shared decision-making in clinical practice. |
