Why Not? Persuading Clinicians to Reduce Overuse.

Objective: To explore how best to deimplement nonrecommended medical services, which can result in excess costs and patient harm.

Methods: We conducted telephone interviews with 15 providers at 3 health systems from June 19 to November 21, 2017. Using the case of nonrecommended imaging in patients with cancer, participants assessed the potential for 7 rationales or "arguments," each characterizing overuse in terms of a single problem type (cost or quality) and affected stakeholder group (clinicians, institutions, society, or patients), to convince colleagues to change their practices.
