Association of Palliative Care Initiation With Acute Healthcare Utilization Among Community-Dwelling Adults Living With Dementia.
Article in Journal of the American Geriatrics Society, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo measure the association between initiating palliative care using the combined criteria of short survival expectations and increased care needs with acute healthcare utilization among community-dwelling people living with dementia.
designA population-level propensity-based overlap-weighted cohort study.
settingOntario, Canada.
participants50,961 community-dwelling people living with dementia between 2010 and 2023, with 1-year follow-up until 2024. We used moderate to severe dementia and the initiation of homecare services as proxies for short survival expectations and increased care needs, respectively. We used linked health administrative data with propensity-based overlap weighting on sociodemographic and clinical factors to address confounding by the indication to receive palliative care. EXPOSURES: Receipt of home-based palliative care within 30 days of homecare initiation.
main outcome measuresIndividual 1-year cause-specific hazards of emergency department (ED) use, hospitalization, and intensive care unit (ICU) admission.
resultsPalliative care was associated with a higher risk of hospitalization in the first 90 days (e.g., hazard ratio (HR) 1.43 at 30 days; 95% confidence interval (CI) 1.25-1.64), which was driven predominantly by hospitalization with palliative intent, but was no longer significantly different beyond 180 days, compared to not receiving palliative care. [Correction added on 31 January 2026, after first online publication: The preceding sentence has been revised in this version.] At 90 days, the cumulative incidence of hospitalization, death, or admission to a nursing home was approximately 20% among those receiving palliative care, compared to 15% in those not receiving palliative care. Although the overall absolute rate of ICU admission was low (0.01 ± 0.1 admissions per month), palliative care initiation was associated with a 186% higher risk in the first 30 days (HR 2.86; 95% CI 1.75-4.69) but not beyond 90 days. Palliative care was not associated with ED use over the following year (HR 1.02; 95% CI 0.72-1.45).
conclusionsThe current approach to delivering palliative care services for community-dwelling people living with dementia in Canada may paradoxically increase early acute care use, likely reflecting system gaps and unmet needs. Given the high prevalence of dementia, there is an urgent need to re-examine homecare delivery models.
