Factors associated with hospitalization from a geriatric short-stay unit (OBI-GER): a retrospective cohort study.
Article in Aging clinical and experimental research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundGeriatric Short-Stay Observation Units (G-SSU) are specialized units designed to improve care for older adults within the emergency department (ED). At our hospital, the Osservazione Breve Intensiva Geriatrica (OBI-GER) was established as a dedicated G-SSU.
aimsThis study aims to characterize the clinical profile of older adults admitted to OBI-GER and identify factors associated with hospitalization within the first 24 h of admission.
methodsRetrospective, single-center study including individuals aged ≥ 75 years, admitted to OBI-GER between August 2023 and August 2024, with frailty and/or delirium during ED stay. Multivariable logistic regression model with stepwise selection was used to assess associations between hospitalization and clinical, functional, laboratory, and organizational variables.
resultsOverall, 353 patients (mean age 86.8 ± 5.5 years, 47.9% male) were included, of whom 109 (30.8%) required hospitalization. The cohort exhibited moderate frailty (median Clinical Frailty Scale = 6, IQR 6-7) and a considerable comorbidity burden (median Charlson Comorbidity Index [CCI] = 6, IQR 5-8), along with a high prevalence of dementia (45%) and polypharmacy (mean 7.1 ± 3.4 medications). Independent risk factors for hospitalization included higher CCI (OR 1.19, 95% CI 1.05-1.35), delirium on the first day of OBI-GER (OR 2.03, 95% CI 1.13-3.64), frequent faller profile (OR 2.66; 95% CI 1.38-5.12), and lower hemoglobin levels at ED admission (OR 0.89, 95% CI 0.79-0.99).
conclusionsDespite their clinical complexity, only one-third of patients admitted to OBI-GER required hospitalization. CCI, delirium, fall history, and hemoglobin levels may serve to stratify hospitalization risk and optimize patient selection for G-SSU.
