How this service works
SEDAN (Strbian 2012 Ann Neurol) for sICH after stroke thrombolysis. Glucose 8.1-12.0 mmol/L (1) or >12.0 (2); early infarct signs (1); hyperdense cerebral artery (1); age >75 (1); admission NIHSS ≥10 (1); max 6. Derivation absolute sICH 1.4%, 2.9%, 8.5%, 12.2%, 21.7%, 33.3% for scores 0-5; no published percent for 6. Not a tPA withhold decision. magent does not assign NIHSS or read CT.
Output
Returns the total SEDAN score (integer 0–6) and the corresponding published absolute sICH risk percentage from the Strbian 2012 derivation cohort (1.4% for 0, 2.9% for 1, 8.5% for 2, 12.2% for 3, 21.7% for 4, 33.3% for 5; no published percent for score 6). The score is advisory only and does not constitute a tPA withhold decision.
Example use cases
Pre-tPA sICH risk stratification in ED
“My stroke patient is 82 years old, NIHSS is 16, admission glucose is 13.5 mmol/L, early infarct signs are present on CT, and the hyperdense MCA sign is also present — what's their SEDAN score and expected sICH risk if we give tPA?”
Low-risk thrombolysis candidate assessment
“Can you calculate the SEDAN score for a 65-year-old with NIHSS of 7, glucose of 6.4 mmol/L, no early infarct signs, and no hyperdense artery on CT? I want to document the sICH risk estimate in the chart.”
Borderline glucose elevation impact on SEDAN
“Our patient is 76 years old, NIHSS 11, glucose is 9.0 mmol/L, no hyperdense artery, early infarct signs present — compute the SEDAN score so I can see how the borderline glucose affects the overall hemorrhage risk.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/sedanWhen to prefer
Use this endpoint when you need a fast, reproducible SEDAN score calculation from structured clinical inputs (age, NIHSS, glucose, CT findings) and want to avoid manual arithmetic errors. Prefer this over generic medical calculators when you specifically need the Strbian 2012 sICH-after-tPA risk score with the published absolute risk percentages. Not intended to replace clinical judgment or serve as a standalone tPA withhold decision tool.
Side effects
- Missing required parameters (age, nihss, early_infarct_signs, hyperdense_artery) returns a validation error
- Providing both glucose_mg_dl and glucose_mmol_l simultaneously is rejected
- Age or NIHSS outside expected integer range may return an error or unexpected result
- Glucose outside the accepted range (2.8–55.5 mmol/L or 50–1000 mg/dL) may be rejected
- Score 6 returns no published sICH percentage as none exists in the Strbian 2012 paper
