Why capacity?
![Page 9: Capacity Assessment in Older People ASM/2018 CAGP... · MMSE and MoCA can be useful in predicting the likelihood of impaired capacity shown to correlate with capacity to consent to](https://reader030.fdocuments.us/reader030/viewer/2022011903/5f10843a7e708231d4497f11/html5/thumbnails/9.jpg)
Capacity is fundamental
● Capacity = ability to make one’s own decisions● Fundamental to ethical principle of respect for
autonomy● Key component of informed consent to medical
treatment● Inherent aspect of all clinician-patient interactions

How to assess capacity
● face-to-face interview● series of open-ended questions that relate to the
decision at hand
![Page 18: Capacity Assessment in Older People ASM/2018 CAGP... · MMSE and MoCA can be useful in predicting the likelihood of impaired capacity shown to correlate with capacity to consent to](https://reader030.fdocuments.us/reader030/viewer/2022011903/5f10843a7e708231d4497f11/html5/thumbnails/18.jpg)
Clinical judgment
● In most cases, capacity judgment is made by the evaluating clinician
![Page 19: Capacity Assessment in Older People ASM/2018 CAGP... · MMSE and MoCA can be useful in predicting the likelihood of impaired capacity shown to correlate with capacity to consent to](https://reader030.fdocuments.us/reader030/viewer/2022011903/5f10843a7e708231d4497f11/html5/thumbnails/19.jpg)

Evaluate at least one of the four decision-making abilities
● understanding● expressing a choice● appreciation● reasoning

Understanding
Know the meaning of information
● What is the illness?● What is the treatment?● Risks and benefit of treatment for illness?
![Page 22: Capacity Assessment in Older People ASM/2018 CAGP... · MMSE and MoCA can be useful in predicting the likelihood of impaired capacity shown to correlate with capacity to consent to](https://reader030.fdocuments.us/reader030/viewer/2022011903/5f10843a7e708231d4497f11/html5/thumbnails/22.jpg)
Expressing a choice
Clearly communicate a choice when presented with multiple treatment options
Frequent reversals of choice in the setting of neurologic or psychiatric conditions may indicate lack of capacity
![Page 23: Capacity Assessment in Older People ASM/2018 CAGP... · MMSE and MoCA can be useful in predicting the likelihood of impaired capacity shown to correlate with capacity to consent to](https://reader030.fdocuments.us/reader030/viewer/2022011903/5f10843a7e708231d4497f11/html5/thumbnails/23.jpg)
Appreciation
Ability to recognize how facts are relevant to the patient personally
Stating how illness
● affects him/her now ● could affect him/her in the future
Impaired insight or delusional beliefs → may lack capacity on basis of failed appreciation of facts

Reasoning
Ability to compare options (comparative reasoning)
Ability to infer consequences of a choice (consequential reasoning)
Ask questions to
● elicit patient’s values● require the patient to compare the consequences of
what he wants to do with what he does not want to do

Risk for impaired capacity
● Older adults● Hospitalized patients● Neurodegenerative diseases (eg, Alzheimer disease
and Parkinson disease)● Traumatic brain injury● Delirium● Psychiatric illnesses

“Altered mental status, assess for competence”
![Page 30: Capacity Assessment in Older People ASM/2018 CAGP... · MMSE and MoCA can be useful in predicting the likelihood of impaired capacity shown to correlate with capacity to consent to](https://reader030.fdocuments.us/reader030/viewer/2022011903/5f10843a7e708231d4497f11/html5/thumbnails/30.jpg)
Capacity vs. Competence
Capacity = Person’s ability to make a decision
Denotes decision-making abilities in the context of a specific choice, such as medical treatment
Clinicians assess capacity to decide whether patients can make their own decisions
Competence = Legal judgment, informed by an assessment of capacity
Relates to whether individuals have the legal right to make their own decisions
![Page 31: Capacity Assessment in Older People ASM/2018 CAGP... · MMSE and MoCA can be useful in predicting the likelihood of impaired capacity shown to correlate with capacity to consent to](https://reader030.fdocuments.us/reader030/viewer/2022011903/5f10843a7e708231d4497f11/html5/thumbnails/31.jpg)

Capacity is a clinical assessment
![Page 33: Capacity Assessment in Older People ASM/2018 CAGP... · MMSE and MoCA can be useful in predicting the likelihood of impaired capacity shown to correlate with capacity to consent to](https://reader030.fdocuments.us/reader030/viewer/2022011903/5f10843a7e708231d4497f11/html5/thumbnails/33.jpg)
How urgent is it?
Depends on
● expected duration of impairment● severity of the impairment● seriousness of the decision
![Page 34: Capacity Assessment in Older People ASM/2018 CAGP... · MMSE and MoCA can be useful in predicting the likelihood of impaired capacity shown to correlate with capacity to consent to](https://reader030.fdocuments.us/reader030/viewer/2022011903/5f10843a7e708231d4497f11/html5/thumbnails/34.jpg)
Capacity is not static
● particularly relevant in hospitalized patients
● treatment of reversible factors such as delirium or medication side effects repeated assessments
● surrogate can be designated

The patient’s MMSE score is 23/30. Is he competent to make decisions about medical treatment?
![Page 36: Capacity Assessment in Older People ASM/2018 CAGP... · MMSE and MoCA can be useful in predicting the likelihood of impaired capacity shown to correlate with capacity to consent to](https://reader030.fdocuments.us/reader030/viewer/2022011903/5f10843a7e708231d4497f11/html5/thumbnails/36.jpg)

Limitations of MMSE, MoCA
● Brief measures of overall cognition are not a substitute for an assessment of capacity
● Higher scores may or may not correlate with full capacity to make decisions
![Page 38: Capacity Assessment in Older People ASM/2018 CAGP... · MMSE and MoCA can be useful in predicting the likelihood of impaired capacity shown to correlate with capacity to consent to](https://reader030.fdocuments.us/reader030/viewer/2022011903/5f10843a7e708231d4497f11/html5/thumbnails/38.jpg)
MMSE and MoCA● can be useful in predicting the likelihood of impaired capacity● shown to correlate with capacity to consent to complex research studies
MMSE can assist in stratifying the risk that an individual with AD lacks capacity
● <16/30: highly correlated with an inability to understand and appreciate, highly correlated with impaired capacity
● >24/30: correlate with retained decision-making abilities● In between: variable sensitivity and specificity → decision-specific
capacity assessment
In one study, a MoCA score ≤22 had a sensitivity of 90 percent for detecting individuals incapable of providing their own consent

Diagnosis is not a substitute for capacity assessment
● Diagnostic labels cannot substitute for an assessment of capacity
● Limited association with severity of mood and other neuropsychiatric symptoms
![Page 42: Capacity Assessment in Older People ASM/2018 CAGP... · MMSE and MoCA can be useful in predicting the likelihood of impaired capacity shown to correlate with capacity to consent to](https://reader030.fdocuments.us/reader030/viewer/2022011903/5f10843a7e708231d4497f11/html5/thumbnails/42.jpg)
Depression and capacity
● less impact on decision making abilities than has been assumed
● Inpatients and outpatients with depression typically perform well on all four decision making abilities

Substance abuseIn 300 psychiatric consultations for decisional capacity,
● 41 percent of patients had substance use disorder.
● Of these, 37 percent were found to have impaired decisional capacity
In comparison, capacity was impaired in
● 17 percent of those with mood disorder● 54 percent of those with cognitive disorder

Fostering trust and respect
Explain that
● one of the main goals of a capacity assessment is to better understand the patient’s own values and preferences
● a judgment will still need to be made based on the available information so that care can proceed

3. nature and extent of one’s assets
4. general plan of distribution of assets to heirs

Substitute decision maker
● impairment severe enough that patient judged to lack the capacity to make a decision
● Ideally chosen by patient in advance● In absence of a designated surrogate, laws
vary● Generally hierarchy of spouse, adult
children, parents, siblings, and other relatives

Formal guardianship● Rarely necessary unless patient has no health care surrogate
or next of kin● Guardian is assigned by a judge in a court of law; legal
determination that the patient is decisionally incompetent
Occasionally necessary if
● multiple first-degree relatives who cannot agree on an approach to medical care despite mediation by the health care team
● next of kin is clearly acting in self interest rather than the best interest of the patient
