Advance directives are legal instruments that allow competent individuals to express, in writing, their preferences for medical treatment in circumstances where they can no longer speak for themselves. They are among the most practical tools available for extending personal autonomy into the period of incapacity that often precedes death, and among the most systematically underutilized. The gap between the availability of advance directives and their actual completion is one of the clearest examples in healthcare of a stewardship failure — a failure of the collective systems that should support individuals in one of the most important planning acts of a lifetime.
The two primary forms of advance directive are the living will and the durable power of attorney for healthcare (also called a healthcare proxy or healthcare agent). A living will specifies the types of treatments the individual does or does not want under particular circumstances — typically focused on circumstances of terminal illness, permanent unconsciousness, or end-stage condition where recovery is not expected. A durable power of attorney for healthcare designates a person — the healthcare agent or proxy — who will make medical decisions on the individual's behalf when the individual cannot make them. The two instruments complement each other: the living will addresses what the person wants; the healthcare agent addresses who will advocate for those wishes and exercise judgment in situations the living will did not anticipate.
POLST (Physician Orders for Life-Sustaining Treatment), now known in many states under variant names, is a related but distinct instrument. Unlike advance directives, which are patient-created documents that express preferences, POLST forms are medical orders signed by a physician or other qualified clinician. They translate advance directive preferences into actionable medical orders that travel with the patient across care settings — from home to emergency room to hospital to skilled nursing facility — and are directly actionable by emergency responders and clinical staff without requiring further physician input. POLST is particularly important for seriously ill or frail elderly individuals for whom the question of emergency intervention is immediately practical rather than hypothetical.
The Patient Self-Determination Act of 1990 required all healthcare facilities receiving Medicare or Medicaid funding to inform adult patients about their right to make advance directives and to inquire whether they have completed one. Despite this federal mandate, completion rates have remained low across the general population — typically estimated between 25% and 35% for adults, with significant variation by age, race, education, and health status. Older adults complete them at higher rates, but still far below 100%. Among young and middle-aged adults, completion rates are distressingly low, despite the obvious relevance: the circumstances that make advance directives necessary are not limited to old age.
The reasons for low completion rates are multiple and interact. First is the psychological barrier: completing an advance directive requires confronting one's own mortality in a concrete and deliberate way, specifying what one does not want done to one's body, and imagining scenarios of severe incapacity. Many people avoid this process not out of ignorance but out of motivated avoidance — the discomfort of imagining those scenarios exceeds the perceived benefit of planning. Second is the access barrier: knowing that advance directives exist, knowing how to complete them, and knowing how to ensure that they are honored requires information and navigation skills that are unevenly distributed. Third is the healthcare system barrier: clinicians often do not initiate advance directive conversations, either because they are not trained to do so, because they are uncomfortable with death discussions, or because the visit is already full of clinical tasks. The structured conversation that would make advance directive completion more likely and more meaningful is rarely had.
Even when advance directives are completed, they frequently fail at the point of use. Documents that are completed but not accessible — locked in a desk drawer, in a lawyer's office, in a storage system not integrated with the clinical record — cannot be acted on. Emergency responders respond to their observations, not to documents they cannot access. Electronic health record integration of advance directives has improved in some systems but remains inconsistent. Family members who are designated as healthcare agents may not be informed of what the directive says, may not know where it is, or may not be willing to advocate for the directives' provisions in the face of clinical pressure or their own grief.
Law 4 — stewardship — is the normative frame that makes advance directive systems a collective rather than merely individual concern. The stewardship obligation runs in several directions simultaneously. Healthcare systems are obligated to create the conditions — through conversation, documentation, accessibility — in which advance directives can function as intended. States are obligated to maintain legal frameworks that are consistent, accessible, and portable across jurisdictions. Employers — particularly those with EAPs — can play a role in supporting advance directive completion as part of a comprehensive approach to health and wellbeing. Families are obligated to have the conversations that make healthcare proxies meaningful rather than nominal.
Law 5 — limits and mortality — is the grounding principle. Advance directives are possible only within a cultural frame that accepts mortality as a reality to be engaged rather than defeated. The medicalization of dying — the default assumption that all available treatments should be applied unless actively refused — creates the conditions in which advance directives are necessary. A healthcare system that treated death as a natural endpoint rather than a medical failure would integrate advance care planning into routine care throughout adulthood, not as an emergency measure reserved for the actively dying.
Law 0 — observation — demands attention to the population-level patterns in advance directive completion and honoring. Racial disparities in completion are well-documented: Black, Hispanic, and Asian American patients complete advance directives at significantly lower rates than white patients, partly due to differences in trust of the healthcare system, cultural differences in end-of-life norms, language barriers, and differential access to the clinician conversations that facilitate completion. Observing these patterns — and designing interventions that address their specific causes rather than applying generic promotion campaigns — is a stewardship imperative.
The advance directive is, at its core, a mechanism for extending the self across time — for ensuring that the values and preferences of the competent person continue to govern the care of the incapacitated one. It is one of the most concrete expressions of human dignity in the face of finitude.
