Using a Patient-Centered Multicriteria Decision Analysis to Assess the Value of Multiple Sclerosis Treatments in the US: A Study Protocol.

Objective: The engagement of patients and family caregivers in value assessment is pivotal since they provide valuable contributions to assessment acceptability and relevance. The proposed study aims to use patient-centered techniques and multicriteria decision analysis (MCDA) to evaluate the values of disease-modifying therapies (DMTs) for multiple sclerosis (MS) from the perspectives of patients and family caregivers living in three 'Deep South' States of the US-Alabama, Louisiana, and Mississippi.

Methods: This study will follow guidance from the Patient-Centered Outcomes Research Institute (PCORI) for patient engagement and two best practice reports for MCDA from the Professional Society for Health Economics and Outcomes Research (ISPOR) to complete value assessment. Throughout the study, we will engage multiple stakeholders, including patients, family caregivers, healthcare providers, and payers. Forty patients with MS and their family caregivers from Alabama, Louisiana, and Mississippi will be invited to participate in this study. We will intensively train them for value assessment knowledge and MCDA before we engage them in MCDA to determine the value of DMTs for MS.

Discussions: Our approach differs from common MCDA since we incorporated a patient-centered framework in this study. Unlike previous studies only briefly inform or prepare participants before the MCDA process, in this study, we will provide basic value assessment trainings for patients and family caregivers to ensure they can effectively engage throughout the patient-centered MCDA process. We expect this study will demonstrate that the patient-centered MCDA approach is feasible and likely leads to improved patients' and family caregivers' engagement in value assessment.
