Evidence stage
CapabilityA demo, benchmark or paper shows the task can be done. Updates what the technology can do — not what employers will do.
Tasks this bears on
Reading ECGs and assessing patients
Recording and interpreting a 12-lead ECG, recognising a heart attack or stroke, and deciding where the patient needs to go.
Being augmented≈ Platform inference
Where this applies
An observational cohort study of 7,313 consecutive patients from multiple clinical sites. The authors derived and externally validated a model for occlusion heart attacks without ST-elevation on the presenting ECG, which they say outperformed practising clinicians and widely used commercial interpretation systems; combined with the clinical judgement of trained emergency personnel, it helped correctly reclassify one in three patients with chest pain. A research model, not a deployed tool.
What this means
Models can catch heart attacks that clinicians miss on the ECG, and work best alongside the crew's judgement.
What it does not yet show
An observational research study; it does not show use in ambulances.
What you can check
Open the Nature Medicine study (doi 10.1038/s41591-023-02396-3) and find "reclassify one in three patients".
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
