Predicting Mortality and Costs After Emergency Department Visits by People With Dementia: Timing and Location Matter.
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. Cited by 1 paper.
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
backgroundPeople with dementia have high rates of emergency department (ED) and hospital utilization, high mortality and costs, and other poor outcomes. To successfully impact the care trajectories of these patients, health care systems must pragmatically identify the correct target population. This study described patterns of ED utilization by people with dementia and explored the accuracy of administrative data models to predict mortality and costs.
methodsRetrospective cohort study of a 20% random sample of Traditional Medicare (TM) beneficiaries with dementia, age ≥ 66 years, and an index ED visit in 2018. One-year mortality and high costs were described, and associations with the timing of prior hospitalizations examined. As a preliminary step to evaluate models based on administrative data only, C-statistics were used to examine the accuracy of eight multivariate models, stratified by the setting of care before and after an ED visit.
resultsThe majority of the 250,343 person cohort of individuals with dementia resided in the community before their index ED encounter (83.9%) rather than in a nursing home (NH, 16.1%), and 34.4% required hospitalization. One-year mortality by location varied from 18.4% (community before and after ED visit) to 47% (admitted NH residents). One-year mortality was 40.3% for those hospitalized within the past month, and 26.2% for those hospitalized 6+ months before the ED encounter. C-statistics were less than or equal to 0.72 for seven multivariate models, and 0.81 for the model examining high costs for NH residents discharged back to their NH.
conclusionsMortality and costs for people with dementia vary by location of care before and after ED encounters, as well as by timing of prior hospitalizations. However, multivariate models using only administrative data lack accuracy, suggesting the need to add pragmatically selected clinical data and/or other measures to better identify the "right patients, at the right time".
