Emergency Department Utilisation and Related Costs in People With and Without Dementia in Their Last Years of Life.
Article in Emergency medicine Australasia : EMA, 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 compare emergency department (ED) utilisation and related costs between people with and without dementia in their last 3 years of life (including the year of death and two full years prior to the year of death).
methodsThis retrospective study used linked data (2013-2015) from 8389 people with dementia and 7813 people without dementia who died in 2015 in Queensland, Australia. ED utilisation data from the Queensland public hospitals were linked to cost data from the National Hospital Costing Data Collection using the patient's unique identifier. Two-sample t-test, Chi-square test and Generalised Estimating Equations regression were used for data analysis.
resultsAfter adjusting for potential confounders, we show that people with dementia were more likely to have ED presentations (OR = 2.001, p < 0.01), short-stay unit admissions (OR = 1.435, p < 0.01) and arrive by ambulance (OR = 2.367, p < 0.01) than those without dementia. The average ED cost per episode for people with dementia is AUD 943.24 compared to AUD 912.82 for people without dementia, with a mean difference of AUD 30.43 (p < 0.01). ED costs for individuals with dementia were 3% higher, amounting to an estimated AUD 5 million for Australia's health sector in 2023.
conclusionPeople with dementia have higher ED utilisation and costs than those without dementia. The results highlight the need for improved ED care models and targeted resource allocation to accommodate the complex needs of people with dementia.
