What is "shared" in shared decision-making? Philosophical perspectives, epistemic justice, and implications for...

Drawing from the philosophical work of Hans-Georg Gadamer and the perspectives of theorists Mikhail Bakhtin and Kenneth Burke, the aim of this paper is to critically reflect on the meaning of the word "shared."

The authors draw on the concept of epistemic justice, which they argue permeates the clinical encounter, to discuss how various forms of, and claims to, knowledge may influence the attainement of shared decision-making in health care contexts. The specific objectives are twofold: first, the authors draw key concepts from key Gadamerian, Burkean, and Bakhtinian philosophical perspectives to consider shared decision-making in relation to two types of epistemic injustice: testimonial and hermeneutic epistemic injustice. Second, building on philosopher Paulo Freire's critical pedagogy, the authors emphasize that major changes in educational structures and systems are required to promote the critical reflexivity required to address issues of epistemic justice, in the broader pursuit of authentic shared decision-making.

They propose three main areas of focus for helath professions education: (a) changes in content (moving from a focus on biomedical knowledge to more content on social sciences) and methods of teaching (more dialogue and the creation of moments of dissonance); (b) a re-examination of teachers' role in promoting epistemic justice; and (c) inclusion of patients as partners.

Without major transformation in what, how, and with whom we teach, future clinicians may be unprepared to enact shared decision-making in a manner that does justice to the various ways of knowing.
