Prevalence, risk factors, and preventive interventions for delirium in older adults living at home and in residential care: a scoping review.
Article in BMC geriatrics, 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
backgroundDelirium is a common yet often underdiagnosed neuropsychiatric syndrome among older adults, especially those residing in the home setting or in residential care. It has been associated with elevated risks of morbidity, mortality, and institutionalization. While delirium has been extensively studied in hospital settings, its prevention and risk factors in the home setting and residential care setting remain insufficiently investigated.
objectivesThis review investigates the prevalence, risk factors, and preventive interventions for delirium among older adults residing in the home setting and in residential care, including assisted home care facilities and nursing homes.
methodsA scoping review was undertaken, including studies of individuals aged ≥ 65 years diagnosed with delirium through validated assessment tools (e.g., DSM, ICD). Eligible studies were to have a primary emphasis on the prevalence, associated risk factors, or preventive strategies related to delirium. Data on study characteristics, methodological approaches, and key findings were extracted and synthesized in a narrative format, supplemented by tables and figures.
resultsSixty studies fulfilled the inclusion criteria. Reported delirium prevalence ranged from 0.1% to 44.0% in the home setting and from 1.0% to 70.3% in residential care. Key risk factors associated with delirium in the home setting and in residential care included cognitive impairment, the presence of dementia, and level of dependence, while age was generally not found to be significantly associated with delirium and was only investigated in residential care. Although various preventive interventions were identified, most studies examined their feasibility rather than their effectiveness in reducing the incidence of delirium.
conclusionDelirium and its risk factors remain insufficiently studied in non-hospital settings. The use of validated diagnostic criteria in community settings is crucial to reduce variation in prevalence estimates, and randomized controlled trials are needed to assess the effectiveness of interventions.
