Prevalence of hospital readmission, related causes and determinants in older people from 2010 to 2022.
Article in Internal and emergency 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
Reducing the rate of re-hospitalization is an important goal to improve the quality of care and reduce healthcare costs. The aims of this study were to assess the prevalence of hospital readmissions, to investigate the causes of index admissions, readmissions and related determinants in an older population. Data from the REgistro dei pazienti per le POlipatologie e politerapie in reparti della rete SIMI (REPOSI) register were used. Older patients (65 + years old) acutely hospitalized and discharged from internal medicine and geriatric wards were followed-up by phone interview after 3 months. Prevalence of hospital readmission was calculated from 2010 to 2022, as well as the patterns of causes of index admission and readmission. Multivariate logistic regression models were used to evaluate the association with 3-month readmissions of patients' variables. Out of 4216 patients evaluated, 828 (19.6%) were re-hospitalized within 3 months. The most frequent causes of index hospitalization were ill-defined conditions (28.6%) and heart failure (12.1%), and those of re-hospitalization heart failure (14.0%) and rehabilitation procedures (11.7%). Multimorbidity, functional dependence and previous hospital admissions were the most important risk factors for re-hospitalization. Among the patients readmitted, 24.3% (201/828) were re-hospitalized with the same condition of their index admission. These results demonstrate that the prevalence of hospital readmission remains high, thus underlying the need for increased medical and social attention towards elderly patients at the time of hospital discharge.
