Nutrition Support in Patients With Delirium: A Retrospective Case Series.

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
aimMalnutrition and delirium are highly prevalent and closely linked, with poor nutritional status increasing delirium risk, and delirium worsening nutritional intake. This study aimed to characterise the nutritional journey for patients with delirium in an acute tertiary hospital.
methodsA retrospective case series was conducted across six general medical units at Austin Hospital, Victoria, between January and July 2024. Of the 157 patients with a positive Confusion Assessment Method score for ≥ 5 days, 100 were randomly selected. Data were extracted from medical records, including demographics, admission details, delirium characteristics, nutrition screening and assessment, and nutrition interventions. Patient-journey timelines were constructed to illustrate key events from hospital admission to discharge. Referral and assessment timelines and length-of-stay data were analysed using Mann-Whittney U test.
resultsSixteen percent of patients with delirium were malnourished. 44% were automatically referred to a dietitian via the malnutrition screening tool, while 56% did not meet referral thresholds. 50% (19/38) of assessments completed in malnourished patients recorded that patients were unable to answer the weight loss question. 15.8% (6/38) of patients responded 'no' to the weight loss question despite documented evidence of weight loss. Malnourished patients with delirium had a longer length of stay than patients with delirium who were not malnourished (median 22.0 days, IQR 15.9-33.8 vs median 11.8 days, IQR 8.6-17.0; p < 0.001).
conclusionThis study highlights issues of suboptimal screening, delayed intervention, and poorer outcomes in those with delirium. Hospitals should improve nutrition screening and referral pathways to facilitate proactive nutrition intervention in patients with delirium.
