Development of FastFrail-a rapid frailty screening tool for medical calls: a development study based on cross-sectional data from an urgent care centre in Norway.
Article in BMJ open, 2025. 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 develop a rapid screening tool for the identification of frailty in medical calls and other out-of-hospital acute care services.
designDevelopment study based on cross-sectional data. A set of potential items were developed based on existing frailty tools and other relevant literature by a panel with geriatric and primary care expertise. The items and the Clinical Frailty Scale (CFS) were administered on a convenience sample of older urgent care patients. Further development of the tool was based on statistical analyses of this data material and final discussions in the panel.
settingUrgent care centre in Norway, data collected between January and August 2022.
participantsAll patients ≥70 years were eligible for inclusion, with the exception of patients triaged to the highest urgency level and patients not able to answer questions with no next of kin present. PRIMARY OUTCOME: Potential items associated with frailty by CFS, measured by explained variance (adjusted R
resultsNine potential items were developed and administered on 200 patients (59% female), of whom 48% were 70-79 years, 38% were 80-89 years and 14% were ≥90 years. The median CFS score was 4 (
conclusionsReceiving help weekly, being homebound and using a walking aid are strong indicators of frailty among urgent care patients. We developed a frailty screening tool for medical calls-FastFrail-consisting of three simple, binary questions (yes/no) on these aspects. We hypothesise that FastFrail can supplement traditional symptom-based triage and enable more accurate assessment of older adults calling for acute medical help. We intend to test the tool in clinical practice.
