In skilled nursing homes and hospital consult liaison psychiatry, requests for a capacity assessment are common. Courts, attorneys, and families often request clinical documentation when pursuing guardianship or activating a medical power of attorney.
For psychiatrists and psychiatric mental health nurse practitioners, assessing medical decision-making capacity is a routine part of clinical care.
A formal “capacity letter” is not always required. In most cases, capacity is evaluated and documented within a clinical encounter. A separate letter may be requested for legal proceedings such as guardianship, and when that occurs, it should reflect the same clinical framework used in the assessment.
This guide outlines how to assess decisional capacity and how to translate that evaluation into documentation that is clinically sound and appropriate for legal review.
Capacity vs Competency
A common point of confusion is the distinction between capacity not competency.
Capacity is a clinical determination made by a treating provider. It is:
- Decision specific
- Time specific
- Subject to change
Competency is a legal determination made by a court.
The clinician’s role is to assess and document capacity. The clinician does not determine competency or assign a guardian.
This distinction is well-established in the literature and central to defensible documentation.
Assessing Capacity Without Formal Cognitive Testing
In skilled nursing homes and hospitals, patients may be unable or unwilling to complete structured cognitive testing such as the MMSE or MoCA.
Capacity assessment does not require standardized testing. It is based on a clinical evaluation of the patient’s decision-making abilities.
Relevant sources of information include:
- Direct psychiatric interview
- Observed behavior during the encounter
- Nursing and staff reports
- Family or collateral information
- Functional limitations related to the decision being evaluated
Capacity may be impaired in a range of conditions, including major neurocognitive disorder, delirium, psychiatric illness, or acute medical conditions.
Appelbaum’s Criteria for Decisional Capacity
The standard clinical framework for assessing capacity is based on four domains:
- Ability to communicate a choice
- Understanding of relevant information
- Appreciation of the situation and its consequences
- Reasoning in comparing options
A capacity determination is based on whether the patient can demonstrate these abilities in relation to a specific decision.
Translating a Capacity Assessment Into Documentation
When a letter or formal documentation is requested, the goal is to describe the clinical findings that support your assessment clearly. The documentation should reflect observed abilities and limitations within the four domains.
Clinical Relationship and Timeframe
Begin by stating your role and the timeframe of care:
The patient has been under my psychiatric care from [date] to [date], or specify the dates of evaluation.
Diagnosis With Severity
Use DSM-5-TR terminology and include severity:
Major neurocognitive disorder due to probable Alzheimer’s disease, severe, with behavioral disturbance
Severity is part of the diagnostic criteria and should be stated.
Functional and Behavioral Findings
Include the findings that prompted the psychiatric consultation. These should be observable and documented:
- Requires assistance with activities of daily living, such as dressing or continence care
- Behavioral disturbances such as agitation, aggression, or physical altercations
- Inability to manage medications or participate in medical decision-making
- Wandering or unsafe behaviors, if present
These findings provide context for the capacity assessment but are not, in themselves, the criteria for capacity.
Capacity Analysis Using Clinical Language
Document the patient’s abilities or deficits within the four domains:
The patient is unable to articulate a clear, consistent choice.
The patient demonstrates limited understanding of their medical condition and treatment.
The patient does not appear to appreciate the consequences of decisions.
The patient demonstrates impaired reasoning when discussing options.
Clinical Impression of Capacity
Capacity should be documented as a clinical finding at the time of evaluation:
The patient demonstrates impaired decisional capacity at this time.
This phrasing reflects the fact that capacity is decision-specific and may change over time.
Treatment Plan and Level of Care
Include your clinical recommendations:
- Continue psychiatric medications for the diagnosed condition
- Continue skilled nursing level of care due to inability to care for self, behavioral disturbance, or safety concerns
- If the patient becomes a danger to self or others again, recommend emergency evaluation
Recommendation for Involvement of Surrogate Decision Makers
Frame this as a clinical recommendation:
Recommend involvement of family, spouse, significant other, or designated medical power of attorney or guardian for medical, treatment, and placement decisions due to current limitations in decisional capacity.
Do not assign a specific individual unless already legally established.
Documentation in Geriatric and Consult Psychiatry
In geriatric psychiatry and consult settings, capacity assessments are frequently required and often occur in the context of complex medical and cognitive conditions.
Defensible documentation:
- Uses the four-domain model of capacity
- Describes observed abilities and limitations
- Avoids legal conclusions
- Reflects the patient’s condition at the time of evaluation
This type of documentation is commonly used in guardianship proceedings, care planning, and coordination with families and facilities.
Closing
Capacity assessments are a routine part of psychiatric practice in skilled nursing homes and hospital consult settings. Clear, structured documentation supports clinical care, communication with families, and interactions with legal systems.
PMHScribe is designed specifically for psychiatric mental health documentation, including geriatric and long-term care settings. It supports clinicians in generating structured notes and clinical letters that reflect real-world psychiatric workflows and the level of detail required in specialized practice.
