Advance care planning (ACP) is one of the things we talk about in our workshops on Personal Planning. We as an organization and I as an individual hold the assumption that ACP will result in goal-concordant end-of-life care. I was surprised to read the following article What’s Wrong With Advance Care Planning? Written by R. Sean Morrison, MD; Diane E. Meier, MD; Robert M. Arnold, MD and published by JAMA. Published online October 8, 2021.
However, the scientific data do not support this assumption. ACP does not improve end-of-life care, nor does its documentation serve as a reliable and valid quality indicator of an end-of-life discussion.
What Is ACP?
The purpose of ACP is to ensure goal-concordant care near the end of
life for patients who lack decisional capacity. It is a process to support
adults in understanding and sharing their values, goals, and preferences
regarding future potential medical care decisions; choosing and preparing a
trusted person(s) to make medical decisions; and documenting these wishes so
that they can be acted on when future medical decisions need to be made. Most
approaches to ACP encourage all adults to participate in the process regardless
of their health status. Advance care planning is distinct from “in-the-moment”
decision making, in which seriously ill patients and their families engage with
their clinicians in goals of care and treatment discussions at present and
regarding their current situation.
If ACP led to higher-quality care at the end of life, it would make
sense to continue efforts to promote it and integrate it into value-based care.
However, a substantial body of high-quality evidence now exists demonstrating
that ACP fails to improve end-of-life care. A 2018 review of 80 systematic
reviews (including 1600 original articles)1 found no evidence that ACP was
associated with influencing medical decision making at the end of life,
enhancing the likelihood of goal-concordant care, or improving patients’ or
families’ perceptions of the quality of care received. A 2020 scoping review2
that included 62 recent high-quality articles also demonstrated no link between
ACP and occurrence of goal-concordant care or patient quality of life.
Additionally, these reviews found no association of ACP with subsequent health
care use, including emergency department visits, hospitalizations, and critical
care. Subsequently, 5 large multisite randomized clinical trials that enrolled
patients with cancer (1117 patients at 23 hospital cancer centers),3 nursing
home residents (12 479 residents from 360 nursing homes),4 older adults in
primary care (759 patients from 8 primary care practices),5 adults with serious
illness (515 patients from 20 outpatient clinics),6 and patients with heart
failure (282 patients from 2 heart failure centers)7 could not identify
meaningful differences in health care use, patient quality of life, or
goal-concordant care between those randomly assigned to receive either ACP or
usual care.
Why Does ACP Not Achieve Its Desired Outcomes?
The inability of ACP to achieve its desired outcomes represents the gap
between hypothetical scenarios and the decision-making process in clinical
practice settings. The success of ACP depends on 8 steps: (1) patients can
articulate their values and goals and identify which treatments would align
with those goals in hypothetical future scenarios; (2) clinicians can elicit
these values and preferences; (3) preferences are documented; (4) directives or
surrogates are available to guide clinical decisions when patients’ preferences
have not changed and they lose enough decisional capacity for their ACP views
to become operative; (5) surrogates will invoke substituted judgment (make the
decision the patient would make if they were able) and base their treatment decisions
on the patient’s prior stated preferences; (6) clinicians will read prior
documents and integrate patient preferences into conversations with surrogates;
(7) previously expressed wishes will be honoured; and (8) health care systems
will commit resources and care delivery to support goal-concordant care.
Scenarios and situations in clinical practice settings rarely reflect
these conditions. Treatment choices near the end of life are not simple,
consistent, logical, linear, or predictable but are complex, uncertain,
emotionally laden, and fluid. Patients’ preferences are rarely static and are
influenced by age, physical and cognitive function, culture, family
preferences, clinician advice, financial resources, and perceived caregiver
burden (eg, need to provide personal care, time off from work, emotional
strain, out-of-pocket or non-covered medical costs), which change over time.
Surrogates find it difficult to extrapolate treatment decisions in the present
from hypothetical discussions with patients that occurred in the past, piece
together what the patient would have wanted, disentangle their own preferences
and emotions, or challenge physicians who recommend different treatments. When
a decision must be made, prior directives are often absent, poorly documented,
or either so prescriptive or so vague that they cannot promote informed
goal-concordant care. Moreover, treatment choices do not occur in a vacuum but
are driven by financial pressures, societal capacity to support patient and
family needs, and institutional/regional cultures and practice patterns.
Should Efforts Address the Problems of ACP Continue?
Some suggest that these data do not diminish the potential positive
effects of ACP. Advocates maintain that although ACP is necessary for good
end-of-life care, it is not sufficient. Why not promote and incentivize
conversations with patients regarding their future values, goals, and treatment
choices?
The problem with accepting these arguments and continuing along the
current path is the potential for unintended consequences. Encouraging the
belief that ACP is essential to good end-of-life care meaningfully detracts
from other initiatives. For example, health care institutions are incentivized
to devote resources that promote and measure ACP and thus direct them away from
equally and perhaps more important areas of clinical care. Research
demonstrates that patients leave clinically-based ACP sessions with serious
misconceptions about life-sustaining treatments and that advance directive are
often misinterpreted by physicians, families, and surrogates.8 In addition, the
presence of an advance directive can inhibit current discussions about goals of
care; this occurred in overwhelmed hospitals during the COVID-19 pandemic when
treatment decisions were made according to written documents rather than
discussions with patients or their surrogates.
If ACP is not essential to high-value end-of-life care, then what is?
One approach is to encourage the appointment of a trusted surrogate decision-maker
(health care proxy) in advance and to focus research and clinical efforts on
improving current shared decision-making between proxies and clinicians.
Psychometrically valid patient-reported outcomes, including the presence and
severity of symptoms and health-related quality of life, can be measured in
real-time; others, such as experiences of “feeling heard and understood by
their clinician” and “receiving desired help for pain,” are being field-tested.
Surveys of surrogates after the death of the patients they have represented are
now a standard quality measure within the Veterans Health Administration, have
shown good linkages with health care processes, and are a more direct measure
of patient and family end-of-life experience than the occurrence of an ACP discussion.
The history of ACP is the story of science working.
There was logic to the belief that ACP would lead to better care for
seriously ill patients. During the last 25 years, studies have evaluated ACP
with various methods and across large groups of patients. Despite the intrinsic
logic of ACP, the evidence suggests it does not have the desired effect. Many
clinicians may be disappointed that promoting conversations with patients well
in advance of needed medical decisions has not improved subsequent care as
hoped. The new research focused on training clinicians and preparing patients and
families to engage in high-quality discussions when actual (not hypothetical)
medical decisions must be made is needed to achieve the outcomes that ACP has
not. The clinical and research communities should learn from the evidence that
does not support prior hypotheses and proceed with different approaches to
improve care for seriously ill patients.
