Empowering patients with the PREPARE advance care planning program results in reciprocal clinician communication.

The patient-directed PREPARE program was associated with greater clinician supportive ACP communication with older adults compared with an AD alone; the effect was most pronounced among Spanish speakers and was mediated by active patient participation. Thus, PREPARE helps patients be more engaged communicators, which in turn encourages clinicians to be more supportive of patients. Enhanced patient-clinician communication represents an important mechanism by which PREPARE may decrease disparities in ACP.
