“…Even in situations where a health care agent cannot be identified, characterizing the individual's values relative to health care decisions while they are able to communicate these values is essential (Naik et al, 2016;Whitlatch, 2008) particularly in the case of dementia (Dassel et al, 2018;Geshell et al, 2019;Orsulic-Jeras et al, 2020;Supiano et al, 2019). The elucidation of patient values to the extent possible is consistent with identifying what matters most to patients, an important component of the 4Ms framework of geriatric care outlined in the Age-Friendly Health Systems movement (Fulmer et al, 2018;Moye et al, 2021), and should inform subsequent care decisions made by guardians for unrepresented patients. It may be useful to engage other members of the interprofessional team-for example, geriatrics care managers, social workers, or nurses-in advance care planning conversations, or at minimum refer patients to self-directed Advance care planning (ACP) resources (Amundson, 2008;Dassel et al, 2019;Gaster et al, 2017;Institute for Health Care Improvement, 2021;Sudore et al, 2014).…”
