Communication About Complementary and Alternative Medicine When Patients Decline Conventional Cancer Treatment: Patients' and Physicians' Experiences

Background: Complementary and alternative medicine (CAM) is a broad set of nonconventional practices used alongside or instead of conventional treatment: The latter poses obvious risks related to cancer prognosis. Patient-physician dialogue about CAM is crucial for patient safety and mutual trust. Little is known about communication in the rare situations when patients decline recommended cancer treatment and consider using CAM. The objective of this study was to explore patients' and physicians' experiences from situations when patients decline recommended cancer treatment and consider using CAM.Materials and Methods: Semi-structured interviews were carried out with 7 CAM-using cancer patients who had declined some or all conventional treatment as well as 10 physicians from oncology and palliative care. Framework analysis was used.Results: Regarding treatment choices, there was a dissonance between physicians' focus on medical reasoning and patients' expression of complex values. Physicians' difficulty in understanding patients' treatment decline was exacerbated when patients considered using CAM, impairing communication even further. Inequalities in roles resulting in power struggles risked pushing both parties toward extreme and inflexible standpoints. Despite these challenges regarding treatment choices and hierarchical roles, both parties considered open and respectful communication as crucial.Conclusions: This study highlights the difficulty of shared decision-making in practice when patients' and physicians' views on treatment decisions deviate in clinically challenging situations. Our results point to a need to address the complexity of these situations, pay attention to patients' values, and improve knowledge among physicians about CAM.
