A survey experiment involving nearly 6,000 U.S. adults found respondents were about 19 percentage points less likely to recommend life-sustaining treatment for a seriously ill patient with dementia than for one without dementia. Advance directives influenced recommendations but did not erase the difference; the study also found that a surrogate’s own preferences mattered.
A survey experiment of nearly 6,000 U.S. adults found that respondents were about 19 percentage points less likely to recommend life-sustaining treatment for a seriously ill patient with dementia than for a similar patient without dementia, even when an advance directive requested treatment. The University of Colorado Anschutz research, published in JAMA Network Open, suggests that documented wishes can shape—but may not fully determine—how surrogate decision-makers approach end-of-life care.
Participants reviewed randomized scenarios about seriously ill, hospitalized older adults. The researchers varied whether the patient had dementia, whether an advance directive asked for life-sustaining or comfort-focused care, and whether a physician recommended treatment. The survey measured participants’ recommendations in those hypothetical cases; it did not track actual clinical decisions or patient outcomes.
For patients with dementia and no advance directive, participants recommended life-sustaining treatment in 15.6% of scenarios. That figure rose to 41.0% when the directive requested life-sustaining treatment and fell to 7.6% when it called for comfort-focused care. For patients without dementia, the corresponding rates were 38.9%, 66.3% and 14.4%.
The researchers also found that surrogate decision-makers’ own preferences influenced recommendations. The study’s lead author, Lauren Hersch Nicholas, said the results indicate that a patient’s stated wishes may not be reflected in care if the person making decisions holds a different view of quality of life. The findings concern survey responses, not proof that dementia itself caused different treatment in real-world hospitals.
When Directives Meet Dementia
The results highlight a potential gap between what people document in advance and what others may recommend when they later make decisions on their behalf. For patients with dementia, respondents were less likely to favor life-sustaining treatment, including in scenarios where the patient’s directive requested it. That difference matters because a directive is intended to communicate preferences when a person cannot speak for themselves.
The study also points to the role of the chosen surrogate. A decision-maker’s personal views may shape how they interpret a directive or apply it to a particular situation. The findings do not establish how often this occurs in actual care, but they support the researchers’ emphasis on discussing a person’s values with the person expected to make decisions.

How the Survey Tested Directives
An advance directive records a person’s preferences for future medical care if they become unable to communicate or make decisions. A surrogate decision-maker is someone authorized or selected to make health care decisions for a patient who cannot make or communicate them. The survey examined how these elements interacted with dementia status and physician recommendations in constructed scenarios.
Earlier research cited in the report suggests that more than two-thirds of older adults may face a situation in which someone else makes end-of-life medical decisions for them. The report also notes that many older adults have not designated a surrogate or documented their preferences. The current study adds evidence about how dementia status and a surrogate’s own preferences can affect recommendations in a survey setting; it does not measure the prevalence of such differences in clinical practice.
“Having a document that clearly states your wishes mattered. But so did the preferences of the person making the decision.”
— Lauren Hersch Nicholas, study lead author and professor of medicine at the University of Colorado Anschutz School of Medicine

What Survey Responses Cannot Show
The findings come from an online survey experiment, so they show how respondents reacted to hypothetical cases—not what clinicians or families ultimately do in real hospital settings. The source report does not provide enough detail here to determine how results varied across participant groups or how closely the scenarios reflected decisions in different clinical circumstances.
The study also cannot establish why respondents made different recommendations. The report says assumptions about life with dementia may play a role, but that is an interpretation rather than a confirmed explanation. It remains unclear how often advance directives are set aside or interpreted differently in actual care, and whether the observed patterns lead to different patient outcomes.

Keeping Care Wishes Current
The researchers argue for ongoing advance care planning, rather than relying on a document alone. Nicholas said people should discuss what matters to them with their chosen surrogate and revisit those conversations as health and circumstances change. The study report does not announce a specific follow-up study or policy change.
For now, the findings offer evidence that directives can influence recommendations while leaving room for dementia status and surrogate preferences to affect them. Whether those patterns hold in actual clinical decisions remains a question for further research.

Key Questions
What did the study find about dementia and life-sustaining treatment?
In the survey scenarios, respondents were about 19 percentage points less likely to recommend life-sustaining treatment for a seriously ill patient with dementia than for one without dementia, including when a directive requested treatment.
Did advance directives affect recommendations?
Yes. For patients with dementia, life-sustaining treatment was recommended in 15.6% of scenarios without a directive and 41.0% when the directive requested it. A directive influenced responses but did not remove the difference associated with dementia status.
Did the study measure actual hospital care?
No. It was a randomized online survey experiment using hypothetical cases. The findings describe participants’ recommendations, not observed treatment decisions or patient outcomes.
What did the researchers say people can do with this information?
The study’s lead author recommended discussing care values with the person chosen as a surrogate and revisiting those conversations over time, rather than relying only on a written directive.
