Derivation and validation of a 90-day unplanned hospital readmission score in older patients discharged form a geriatric ward.
Article in European geriatric medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo derive and validate a 90-day unplanned hospital readmission (UHR) score based on information available to non-hospital based care providers.
methodsRetrospective longitudinal study with cross-validation method. Participants were older adults (≥ 65 years) admitted to a geriatric short-stay department in a general hospital in France. Patients were split into a derivation cohort and a validation cohort. We recorded demographic information, medical history, and concurrent clinical characteristics. The main outcome was 90-day UHR. Data obtained from hospital discharge letters were used in a logistic regression model to construct a predictive score, and to identify risk groups for 90-day UHR.
resultsIn total, 750 and 250 aged adults were included in both the derivation and the validation cohorts. Mean age was 87.2 ± 5.2 years, most were women (68.1%). Independent risk factors for 90-day UHR were: use of mobility aids (p = .02), presence of dementia syndrome (p = .02), history of recent hospitalisation (p = .03), and discharge to domiciliary home (p = .005). From these four risk factors, three groups were determined: low-risk group (score < 4), medium-risk group (score between 4 and 6), and high-risk group (score ≥ 6). In the derivation cohort the 90-day UHR rates increased significantly across risk groups (14%, 22%, and 30%, respectively). The 90-day UHR score had the same discriminant power in the derivation cohort (c-statistic = 0.63) as in the validation cohort (c-statistic = 0.63).
conclusionsThis score makes it possible to identify aged adults at risk of 90-day UHR and to target multidisciplinary interventions to limit UHR for patients discharged from a Geriatric Short-Stay Unit.
