Patient involvement in reflective multicriteria decision analysis to assist decision making in oncology.

Patient involvement in drug evaluation decision making is increasing. The aim of the current study was to develop a multi-criteria decision analysis (MCDA) framework that would enable the inclusion of the patient perspective in the selection of appropriate criteria for MCDAs being used in the value assessments of oncologic drugs. A literature review was conducted to identify and define criteria used in drug assessments from patient perspectives. The Evidence and Value: Impact on Decision Making methodology was used to develop a MCDA framework. Identified criteria were discussed by a sample of oncology patient association representatives who decided which criteria were important from patient perspectives. Selected criteria were rated by importance. The preliminary MCDA framework was tested through the assessment of a hypothetical oncology treatment. A discussion was carried out to agree on a final pilot MCDA framework. Twenty-two criteria were extracted from the literature review. After criteria discussion, sixteen criteria remained. The most important criteria were comparative patient reported outcomes (PRO), comparative efficacy and disease severity. After the discussion generated by the scoring of the hypothetical oncology treatment, the final pilot MCDA framework included seven quantitative criteria ("disease severity", "unmet needs", "comparative efficacy / effectiveness", "comparative safety / tolerability", "comparative PROs", "contribution of oncological innovation") and one contextual criterion ("population priorities and access"). The present study developed a pilot reflective MCDA framework that could increase patient's capability to participate in the decision-making process by providing systematic drug assessments from the patient perspective.
