Care-Model Redesign, Not Education or Decision Aids Alone, Moves Advance Care Planning Documentation in Dementia

Question: What interventions and care-model approaches have been shown to increase completion and documentation of advance care planning in community-dwelling older adults with cognitive impairment or dementia?

Answer

Taken together, the retrieved papers support a narrow and somewhat deflationary answer: multicomponent programmes that bundle education, structured conversation, and explicit documentation support are the only intervention class with consistently reported gains in advance care planning (ACP) uptake, and even these are supported largely by small, methodologically uneven studies concentrated outside community-dwelling dementia populations [1]. Decision aids and knowledge-translation tools reliably improve knowledge, confidence, and decisional conflict but have not been shown to move documented completion [3]. Most consequentially, the one controlled test in the retrieved set found that structured team-based conversation training produced no improvement in serious illness conversation documentation relative to passive dissemination [10], and patient-reported shared decision-making was only weakly and non-significantly associated with documented ACP among adults with Alzheimer disease and related dementias (ADRD), where documentation prevalence was approximately 5% [15]. Across these papers the active ingredients appear to be structural rather than educational: a designated accountable facilitation role, systematic case-finding, and documentation templates embedded in existing workflows [5] [9].

Multicomponent programmes are the only intervention class with consistent uptake effects

A rapid review of 25 studies (2015–2025, 12 countries) sorted dementia ACP interventions into three categories — video decision aids, web-based tools, and multicomponent programmes combining education, structured discussions, and documentation support for people with dementia, families, and professionals — and reported that primary outcomes consistently showed increased ACP uptake across all three, while secondary outcomes such as carer burden, hospitalisation, quality of life, and burdensome treatment rates were mixed [1]. That review's own quality appraisal ranged from poor (n=8) to high (n=6) with common small samples and unclear randomisation, so the "consistent" finding rests on a weak base [1]. A separate scoping review of 40 studies concluded that structured communication models and psychoeducational programmes are the promising intervention types, but that few have been fully adapted for dementia [6].

Decision aids and knowledge-translation tools shift process outcomes, not documented completion

An umbrella review of 22 reviews covering 32 knowledge-translation interventions found ACP to be the most common decision topic (21 of 32 interventions), with most targeting care partners only (n=16) or dyads (n=13) and only three targeting individuals with dementia alone; reported benefits were increased knowledge and confidence and decreased decisional conflict [3]. Those are upstream process measures, not completed or documented plans, and the review does not report documentation as an outcome [3]. A designed website with three AI-driven assistants for value exploration, knowledge, and decision support achieved an excellent usability rating and significantly improved value exploration, knowledge, and decisional confidence in a small comparative evaluation (n=12), again without documentation endpoints and without a dementia-specific sample [14].

Training clinicians in conversation skills does not, by itself, raise documentation

A quasi-experimental study across 13 primary care clinics (2,368 patients, mean age 75.8, Charlson index 4.88) compared structured team-based Serious Illness Care Program training against toolkit dissemination alone and found no statistically significant improvement in serious illness conversation documentation in either the pandemic or post-toolkit period; the authors concluded that educational interventions must be supported by structural change, workflow integration, and organisational leadership [10]. In linked survey–EHR data from 3,635 adults with ADRD, high patient-reported shared decision-making was associated with documented ACP only in unadjusted analysis (PR 1.44, 95% CI 1.04–1.99), attenuating to non-significance after adjustment (aPR 1.28, 95% CI 0.93–1.77), whereas the association remained significant among adults without ADRD [15]. Qualitative work in English primary care explains why: practitioners described reliance on tick-box approaches, inconsistent preparation, uncertainty about care plan purpose and ownership, and time-pressured checklist-driven encounters that undermine shared decision-making [13].

Care-model redesign around an accountable role and systematic identification is where documentation gains plausibly originate

The PriDem programme's primary care-led post-diagnostic model, in which Clinical Dementia Leads worked with general practices to strengthen care systems, confirmed mechanisms including improved review processes leading to enhanced care plan personalisation and staff training increasing confidence, with care planning templates functioning as educational resources and pre-implementation training and champion identification critical to success; role ambiguity and capacity concerns acted as negative mechanisms [5]. In a primary care cohort of 39,079 adults, an automated robotic process using palliative care process markers plus GP validation added 131 patients (24% of those flagged) to the palliative care register and raised the register's capture of subsequent deaths from 25.4% to 35.5% [9]. Structurally embedding frontline workers is a plausible delivery route but is currently unrealised: nursing assistants in community care described themselves as not structurally involved in ACP and in need of additional knowledge and skills, with team culture shaping both opportunity and motivation [4]. A manualised, non-clinician-facilitated dyadic intervention (NIDUS-Family, delivered by non-clinical facilitators in 6–8 telephone or video sessions) improved goal attainment at 18 and 24 months, though secondary outcomes including care recipient functioning, quality of life, and time to care home admission or death were not significant, and ACP documentation was not an endpoint [12].

Documentation is worth pursuing because completeness tracks goal-concordant care, and dementia decedents document more yet still face greater decisional burden

Among 5,622 U.S. decedents, 42.7% had both a living will and durable power of attorney and 28.9% had none, with documentation rising substantially around 2014; any documentation was associated with lower likelihood of life-sustaining treatment (aRR 0.85, 95% CI 0.74–0.98) and higher likelihood of hospice enrolment (aRR 1.43, 95% CI 1.28–1.60) and out-of-hospital death (aRR 1.11, 95% CI 1.06–1.18), with only modest incremental benefit from two documents versus one [11]. Decedents with dementia were more likely than those without to have completed advance directives (81.3% vs 69.1%) yet had higher decision-making needs in the final days of life (54.3% vs 47.2%) and more frequent involvement of children or grandchildren (63.9% vs 45.6%) [8]. Documenting a directive is therefore not the same as pre-empting the decisional load that falls on surrogates [8].

Conflicts and gaps

The central conflict is between reviews reporting that primary ACP outcomes "consistently" improved [1] and the single controlled primary care comparison in this set, which found no documentation gain from structured training [10]. The two are reconcilable only if "uptake" in the reviews means something other than a documented plan — which the umbrella review's reliance on knowledge, confidence, and decisional conflict outcomes suggests it often does [3].

The population specified in the question is largely missing. The rapid review spans dementia care broadly without separating community-dwelling from residential settings [1]; the documentation-completeness and shared decision-making analyses are retrospective, using decedents or EHR-linked survey cohorts rather than incident community cohorts [11] [15]; and the community-dwelling cognitively impaired population is addressed only by an RCT protocol whose results are not yet reported [2]. A direct contest between scripted medical and flexible psychosocial ACP approaches remains unresolved on outcomes: GPs distinguished the two by understanding, trust, readiness, and momentum and judged that skill in both would improve tailoring, but no completion or documentation comparison was reported [7]. Whether documents completed by care partners count toward "completion" is nowhere specified.

What would change the answer

A pragmatic cluster-randomised trial in community-dwelling MCI and mild dementia with EHR-extracted documented ACP as the primary outcome, crossing three factors — documentation template embedded in the workflow, a designated accountable facilitator role (nurse, Clinical Dementia Lead, or trained non-clinical facilitator), and systematic case-finding — would separate the structural ingredients from the educational ones that the null primary care trial implicates [10] [5] [9]. Completion of the virtual nurse-led primary palliative care RCT in community-dwelling older adults with cognitive impairment would supply the first randomised documentation data in the target population [2]. A head-to-head trial of the medical versus psychosocial ACP approach with documentation and surrogate-decisional-burden co-primary endpoints would settle the approach question [7]. Finally, extending a dyadic goal-setting intervention to include ACP documentation endpoints would test whether non-clinician delivery can carry documentation as well as goal attainment [12].

How this survey was made

This survey answers one question: “What interventions and care-model approaches have been shown to increase completion and documentation of advance care planning in community-dwelling older adults with cognitive impairment or dementia?”

We keep our own collection of recent preprints and refresh it every day from bioRxiv, medRxiv, arXiv, PsyArXiv, SocArXiv and ChemRxiv. For each survey, we search that collection for recent work and keep the strongest matches: papers that use the same terms as the question, and papers on the same topic in different words.

The text was written from the titles and abstracts of those papers; the full texts were not read. Statements that draw on a particular paper are marked with a number in brackets. The reference list just above is the 15 papers whose work this text draws on, chosen from the 90 papers those searches returned; the rest of the shortlist is not printed. It is not a complete review of everything published on the question.

Treat this as a starting point and a reading list, not a peer-reviewed review. The searches behind this survey ran on October 22, 2026 and covered work from the previous two years.
