Do ward changes affect outcomes differently in people living with dementia?
Observational study in Age and ageing, 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
backgroundWard changes during hospital admissions are associated with poorer outcomes, but their impact on people living with dementia is unknown.
objectiveTo examine whether individuals with dementia are more adversely affected by ward changes.
settingFour hospitals within a UK NHS Trust. SUBJECTS: Individuals aged ≥65 years.
methodsThis service evaluation included data from 01/2023-02/2024. Generalised estimating equations were used to fit linear and logistic regression models. Associations between ward changes, dementia status and their interaction on three outcomes-length of stay (LOS), inpatient mortality and discharged to a care home-were examined. Fully adjusted models accounted for demographic, socioeconomic factors and hospital site.
results27,140 admissions, 19,392 unique individuals (2760 with dementia) were included. Mean age at first admission 79.0 (SD 8.1). In the fully adjusted LOS model, both ward changes (β = 5.2, P < .001) and the interaction with dementia (β = 1.7, P < .001) were associated with longer LOS. In the fully adjusted mortality model, dementia was associated with increased risk of mortality (OR = 1.4, P = .013) but there was no interaction effect of ward changes and dementia. In the fully adjusted care home admission model, dementia (OR = 4.4, P < .001) and ward changes (OR = 1.3, P < .001) were associated with increased risk, without evidence of interaction.
conclusionsOur results suggest that ward changes disproportionately affect LOS, but not mortality or discharge destination, in people living with dementia. Minimising ward transfers may improve outcomes for all older adults but is particularly important in dementia care to reduce the risk of extended LOS and potential associated inpatient harm.
