Recognizing the need to thoughtfully consider and address the challenges and opportunities in efforts to improve care quality and value, the Roundtable on Quality Care for People with Serious Illness of the National Academies of Sciences, Engineering, and Medicine held the public workshop Integrating the Patient and Caregiver Voice into Serious Illness Care, on December 15, 2016, in Washington, DC. This workshop was the first in a series planned by the roundtable, and was designed specifically to bring together diverse personal perspectives and experiences about priorities and values that are important to patients and families coping with serious illness, and to consider solutions that support integration of these priorities and values in practice. This publication summarizes the presentations and discussions from the workshop.
