Association of pre- and postoperative delirium with functional status at discharge after hip fracture: findings from the Gruppo Italiano di Ortogeriatria (GIOG 2.0) study.
Article in European geriatric medicine, 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
purposeEvidence on how the timing of delirium onset influences functional outcomes after hip fracture is scarce, yet is crucial for informing service planning and optimizing orthogeriatric care pathways. We therefore examined the association between delirium occurring at distinct perioperative phases and functional status at discharge in older patients undergoing hip fracture surgery.
methodsThis multicenter prospective cohort study included patients aged ≥ 65 years who underwent hip fracture surgery between July 2019 and June 2024 at 12 Italian orthogeriatric centers. Delirium was assessed with the 4AT from the day before surgery through postoperative day three. Poor functional status at discharge was defined as a Cumulated Ambulation Score ≤ 2. Associations of preoperative, postoperative, and preoperative + postoperative delirium with poor functional status were examined using multivariable logistic regression adjusted for age, sex, comorbidity, pre-fracture activities of daily living, pre-fracture ambulation, and time-to-surgery > 48 h.
resultsA total of 1492 patients were included (median age 84 years, Q1-Q3: 79-89; 76.9% female). Delirium occurred in 444 (29.8%) patients: 34 (2.3%) had preoperative delirium, 182 (12.2%) postoperative delirium, and 228 (15.3%) both. The combined presence of preoperative and postoperative delirium was significantly associated with higher odds of poor functional status at discharge (Odds Ratio: 1.57; 95% Confidence Interval: 1.13-2.20) versus no delirium.
conclusionDelirium persisting from the preoperative to the postoperative phase was associated with poor functional status at discharge. Systematic assessment of delirium in both phases may help identify older hip fracture patients at increased risk of poor functional outcome.
