Impact of delirium subtypes on survival in older adults hospitalised for acute heart failure: a prospective study in an acute geriatric unit.
Observational study in European geriatric medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
purposeDelirium is a common complication in older adults hospitalised for acute heart failure (AHF), but its incidence, subtypes, and short-term outcomes remain poorly characterised in the very old population. This study aimed to determine the prevalence and incidence of delirium in patients admitted to an acute geriatric unit (AGU) with AHF, describe its subtypes, and assess their impact on 90-day post-discharge survival.
methodsThis prospective observational study included older adults hospitalised for AHF in an AGU between April 2022 and November 2024. Delirium was assessed using the 4AT and DSM-5 criteria and categorised as prevalent (on admission) or incident (during hospitalisation). Delirium psychomotor subtypes were classified as hyperactive, hypoactive, or mixed. Sociodemographic, clinical, and follow-up data were collected. Ninety-day survival was evaluated using Kaplan-Meier curves and Cox regression models.
resultsAmong 399 patients (median age 87.4 years, 52% female), 132 (33%) experienced delirium, with 13.8% classified as prevalent and 19.2% as incident cases. Among those with delirium, 48% presented with the hyperactive, 31% with hypoactive, and 21% with the mixed subtype. In multivariable regression analysis, adjusted for relevant covariates, the hypoactive (adjusted HR 2.03, 95% CI 1.13-3.64) and mixed (adjusted HR 2.28, 95% CI 1.18-4.43) subtypes-but not the hyperactive subtype-were independently associated with an increased risk of death.
conclusionsDelirium is common in very old patients hospitalised for AHF. Our findings indicate that the hypoactive and mixed subtypes are independently associated with poor 90-day post-discharge survival, highlighting the importance of their active identification and management.
