[Rockwood Frailty Index as a prognostic classifier in hospital at home: an observational survival study].
Article in Atencion primaria, 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
objectiveTo evaluate the association between the Rockwood Frailty Index (RFI) and survival across three populations in a Hospital-at-Home Unit (HaH): complex chronic patients, non-oncologic palliative patients (advanced organ failure, severe functional limitation and impaired physiological reserve) and oncologic palliative patients.
designRetrospective longitudinal observational cohort study. SITE: Hospital-at-Home Unit of the Hospital Universitari i Politècnic La Fe (Valencia, Spain).
participantsPatients aged 65 or older discharged between January 2021 and December 2024, with an RFI recorded at admission and follow-up in the Case Management programme. 2,610 patients were included (53.8% complex chronic; 34.0% non-oncologic palliative; 12.2% oncologic palliative).
interventionsNone; observational study with no intervention. MAIN: measurements Survival (time to death) using Kaplan-Meier curves, log-rank tests and multivariate Cox regression, adjusted for demographic (age, sex), clinical (Charlson and Barthel indices, diagnosis-related group, prior emergency admissions) and laboratory variables (albumin, C-reactive protein, glomerular filtration rate).
resultsSignificant differences were observed between groups (χ
conclusionsThe RFI is a powerful independent prognostic predictor across all three populations, outperforming comorbidity and functional dependency. A threshold of ≥0.53 identifies non-oncologic patients with advanced organ failure and severe functional impairment -median survival below nine months- without a formal palliative designation. Its implementation in Primary Care electronic health records would enable early identification of this population and anticipate end-of-life palliative care, regardless of diagnosis.
