BackgroundThe debate within the multiple sclerosis (MS) community initiated by the chronic cerebrospinal venous insufficiency (CCSVI) hypothesis and the subsequent liberation procedure placed some people with MS at odds with health care professionals and researchers.ObjectiveThis study explored decision making regarding the controversial liberation procedure among people with MS.Subjects And MethodsFifteen people with MS (procedure, n=7; no procedure, n=8) participated in audiotaped semistructured interviews exploring their thoughts and experiences related to the liberation procedure. Data were transcribed and analyzed using an iterative, consensus-based, thematic content-analysis approach.ResultsParticipants described an imbalance of motivating factors affirming the procedure compared to hesitating factors that provoked the participant to pause or reconsider when deciding to undergo the procedure. Collegial conversational relationships with trusted sources (eg, MS nurse, neurologist) and ability to critically analyze the CCSVI hypothesis were key hesitating factors. Fundraising, family enthusiasm, and the ease of navigation provided by medical tourism companies helped eliminate barriers to the procedure.ConclusionKnowledge of factors that helped to popularize the liberation procedure in Canada may inform shared decision making concerning this and future controversies in MS.
