Ethical & Legal Aspects of Care
Advance care planning, advance directives, and surrogate decision-making are the legal and ethical tools that help ensure your wishes are honored during a serious illness. This page explains what the research shows about how widely these documents are completed, how effective ACP interventions have been in practice, and what Medicare now pays for to support caregiver training and decision-making.

Contested evidence notice: The effectiveness of advance care planning as commonly practiced is actively debated in the peer-reviewed literature. This page presents both supportive and null/contested findings with equal weight. See Morrison et al. (2021) and the SUPPORT trial (1995).
Scope: advance directive prevalence, ACP effectiveness evidence, communication intervention trials, caregiver training billing pathways, and surrogate decision-support programs. This page does not provide legal advice or clinical protocols.
What the evidence shows
A nationally representative study (Yadav et al., Health Affairs 2017) found that approximately 36.7% of U.S. adults have completed any type of advance directive — with substantially lower completion rates among younger adults and racial/ethnic minority populations. The majority of Americans have no documented end-of-life preferences at the time of a serious illness.
A 2021 JAMA viewpoint (Morrison, Meier, Arnold) argues that advance care planning as commonly practiced is NOT consistently associated with reduced aggressive end-of-life care in the existing evidence base. This position is contested: other research supports benefit in specific contexts (earlier disease stage, structured facilitated conversations, longitudinal follow-up). Clinicians and systems designers should weigh this evidence tension when investing in ACP programs.
The SUPPORT trial (1995) found that a structured nurse-led communication and advance care planning intervention in seriously ill hospitalized patients produced no statistically significant improvement in patient-physician communication, DNR orders, pain control, or resource use — demonstrating that information delivery alone does not translate into preference-concordant care.
The CMS CY2025 Physician Fee Schedule Final Rule (CMS-1807-F) established Caregiver Training Services (CTS) codes G0541, G0542, and G0543 — creating a Medicare reimbursement pathway for training family caregivers and surrogate decision-makers in care management skills, safety techniques, and disease-specific care routines.
The CMS GUIDE (Guiding an Improved Dementia Experience) Model, launched July 2024, provides $2,500 in annual respite and care coordination support for family caregivers and surrogate decision-makers of Medicare beneficiaries with dementia — representing the first CMS innovation model specifically targeting informed surrogate support and caregiver burden reduction as primary goals.
