Advance Care Planning Assessment

Advance care planning assessment is a structured clinical process used in geriatric medicine to identify, document, and align a patient's medical preferences with their values before a health crisis makes real-time decision-making impossible. This page covers the definition of the assessment process, the mechanisms through which clinicians conduct it, the scenarios in which it is most commonly applied, and the boundaries that determine which planning instruments or interventions are appropriate. For older adults managing complex, chronic conditions, the stakes of this process are high: without documented preferences, default medical interventions may directly contradict a patient's stated wishes.

Definition and scope

Advance care planning (ACP) assessment refers to the formal evaluation of a patient's understanding of their health trajectory, their values and goals, and the legal instruments available to express those preferences. The Centers for Medicare & Medicaid Services (CMS) recognizes advance care planning as a billable clinical service under Medicare (CPT codes 99497 and 99498 cover the first 30 minutes and each additional 30 minutes, respectively), reflecting its standing as a discrete medical activity rather than incidental counseling.

The scope of ACP assessment spans three domains:

Cognitive and decisional capacity — determining whether the patient can understand, reason about, and communicate treatment preferences
Values clarification — identifying what quality of life, functional outcomes, and care settings matter most to the patient
Document status — reviewing existing legal instruments such as a durable power of attorney for healthcare (DPOA-HC), living will, or POLST (Physician Orders for Life-Sustaining Treatment) form

The National POLST Paradigm maintains a state-by-state registry of POLST form validity, because the legal enforceability of these forms varies across the 50 states. An assessment that fails to verify whether a form is legally current in the patient's state of residence introduces direct care risk.

Advance care planning assessment sits within the broader framework of comprehensive geriatric assessment, though it has a distinct legal and ethical dimension not shared by functional or nutritional screening.

How it works

A complete ACP assessment follows a structured sequence that integrates clinical judgment, communication, and documentation review.

Phase 1 — Capacity screening. Before preferences can be solicited, clinicians establish whether the patient retains decisional capacity. This is distinct from cognitive screening (see cognitive screening with MMSE and MoCA); capacity is decision-specific, not a global cognitive score. The MacArthur Competence Assessment Tool for Treatment (MacCAT-T), developed by researchers Grisso and Appelbaum and described in peer-reviewed literature, is one structured instrument used for this purpose.

Phase 2 — Health trajectory discussion. The clinician presents a clear, jargon-free description of the patient's likely disease course. For a patient with advanced heart failure, this includes likely hospitalization frequency, functional decline, and probable causes of death. The American College of Physicians (ACP) and the American Geriatrics Society (AGS) both publish guidance supporting prognosis-informed conversations as the clinical standard.

Phase 3 — Values clarification. Structured prompts help patients articulate priorities. Common frameworks include the Five Wishes document (legally valid in 47 states as of the most recent update from Aging with Dignity) and the Serious Illness Conversation Guide developed by Ariadne Labs.

Phase 4 — Document review and update. Existing documents are reviewed for completeness, currency, and consistency with expressed preferences. A DPOA-HC that names a deceased or estranged surrogate, for example, requires immediate revision.

Phase 5 — System entry and communication. Completed documents are entered into the electronic health record and, critically, communicated to the designated healthcare proxy, relevant specialists, and any facilities where the patient receives care. The Joint Commission has standards requiring that advance directive status be documented at admission (Joint Commission Standard RI.01.05.01).

Common scenarios

ACP assessment is triggered by specific clinical and situational conditions rather than applied uniformly to all older adults.

Newly diagnosed serious illness. A patient receiving a diagnosis of stage IV malignancy, end-stage renal disease, or advanced dementia is a primary candidate. At this stage, prognosis is definable and decisions about dialysis, mechanical ventilation, or artificial nutrition are practically imminent.

Functional decline crossing a threshold. When a patient transitions from independent living to requiring assistance with 3 or more activities of daily living (ADLs), the care burden and hospitalization risk rise sharply, making documented preferences operationally necessary. The relationship between functional status in older adults and care planning urgency is well established in geriatrics literature.

Pre-surgical or pre-procedural planning. Hospitals accredited by The Joint Commission are required to document advance directive status before elective procedures. This creates a formal checkpoint for ACP review.

Surrogate identification. When a patient lacks existing documentation and cognitive screening reveals early decline, identifying and legally designating a surrogate decision-maker before full incapacity is a time-sensitive priority.

Transition between care settings. Discharge from hospital to skilled nursing facility, or from home to memory care, represents a high-risk transition during which previously documented wishes are frequently lost or ignored. The regulatory context for these transitions — including requirements under 42 CFR Part 483 for nursing facilities — is covered in depth at regulatory context for geriatrics.

Decision boundaries

Not every older adult requires the same depth of ACP assessment, and the instrument or intervention selected depends on defined clinical thresholds.

POLST vs. advance directive. A POLST form translates preferences into immediately actionable medical orders — appropriate for patients with serious illness or advanced frailty. An advance directive (living will plus DPOA-HC) is a legal planning document suited to patients who are not yet acutely ill but want preferences on record. Applying POLST documentation to a healthy 68-year-old without serious illness is outside its intended scope according to the National POLST Paradigm clinical guidance.

Full assessment vs. update visit. A patient with existing, current, and legally valid documents who has had no significant change in health status requires only a brief review — not a full five-phase assessment. CMS billing guidance distinguishes between an initial ACP encounter and a subsequent revisit; clinicians who bill both at the same intensity without documentation of changed circumstances face audit risk.

Capacity present vs. absent. When decisional capacity is confirmed, the patient is the primary party. When capacity is absent, the assessment pivots to surrogate counseling, focusing on the surrogate's understanding of substituted judgment (what would the patient have wanted?) versus best-interest standards. This boundary is codified differently across state law, and legal consultation may be required in contested cases.

Integration with palliative care referral. ACP assessment does not constitute palliative care, but findings frequently trigger a palliative care consultation for older adults. The clinical threshold for referral — typically a positive response to the "surprise question" ("Would you be surprised if this patient died within 12 months?") — is a decision tool used by geriatricians and hospitalists. Patients and families seeking broader context about geriatric care coordination can find orientation material at the geriatrics site index.
