This document discusses the potential for conflicts of interest between patients and advocacy groups that receive funding from medical companies. It proposes three recommendations to address this issue. First, it recommends ensuring a diverse mix of patient perspectives in research. Second, it recommends providing guidance on identifying and mitigating financial and non-financial conflicts of interest for patients involved in research. Third, it recommends disclosing any conflicts of interest that patients who are study personnel may have, as is done for other study staff. The goal is to prevent medical companies from inappropriately influencing or "capturing" the patient voice through advocacy organizations.
