How this service works
Nor 2005 ROSIER: seven caller-assigned flags. Loss of consciousness or syncope −1, seizure −1; new acute-onset (or on awakening) asymmetric face, arm, or leg weakness, speech disturbance, and visual field defect +1 each. Range −2 to +5. stroke_more_likely if score > 0. Score ≤ 0 does not exclude stroke. Not a diagnosis, not NIHSS, and not a medical device. magent does not examine the patient or collect a time of onset.
Output
Returns the computed ROSIER total score (integer ranging from −2 to +5) and a stroke_more_likely flag (true if score > 0, false if ≤ 0), along with the individual point contributions of each input flag
Example use cases
Emergency triage stroke screening
“I have a patient in the ED with sudden onset right-sided arm and leg weakness and slurred speech, no seizure, no syncope, no facial droop, and no visual field changes — what's their ROSIER score and is stroke more likely?”
Clinical documentation support tool
“Can you run the ROSIER score for a patient presenting with new facial weakness on the left, no arm or leg weakness, no speech problem, no visual field defect, no syncope, and a witnessed seizure before arrival?”
Automated neurology referral trigger
“Check the ROSIER score for a patient who woke up with facial weakness, arm weakness, and a visual field defect but no leg weakness, no speech disturbance, no syncope, and no seizure history — does the score suggest stroke is more likely?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rosierWhen to prefer
Use this endpoint when you need a fast, reproducible computation of the ROSIER stroke-screening score from caller-supplied clinical flags; prefer it over manual calculation when integrating stroke triage logic into an automated clinical workflow, EHR augmentation, or emergency decision support agent where the seven ROSIER boolean inputs have already been assessed by a clinician
Side effects
- Missing any of the seven required boolean query parameters returns a validation error
- Passing non-boolean values for flags causes a schema validation failure
- Score ≤ 0 does not exclude stroke — the endpoint returns a result but the caller must not interpret it as ruling out stroke
- Endpoint does not collect or validate time of onset — caller must supply clinically determined flags
