How this service works
Grossman 2007 Boston Syncope from eight caller-assigned flags: ACS signs/symptoms, conduction disease, worrisome cardiac history, valvular heart disease, family history of sudden death, persistent abnormal ED vitals, volume depletion, and primary CNS event. high_risk (Boston-positive) iff any is true; low_risk iff none. Adult (enrolled 18+). Not a disposition or admission order. magent does not examine the patient or interpret ECG/hematocrit. Not San Francisco Syncope, EGSYS, ROSE, or OESIL.
Output
Returns a Boston Syncope risk classification: high_risk (Boston-positive) if any of the eight clinical flags is true, or low_risk if all eight are false. The result reflects caller-assigned inputs only — the endpoint does not independently examine the patient, interpret ECGs, or assay laboratory values.
Example use cases
ED triage risk stratification for syncope
“I have a 67-year-old male syncope patient in the ED. He has a worrisome cardiac history and persistent abnormal vitals, but no ACS signs, no conduction disease, no valvular disease, no family history of sudden death, no volume depletion, and no CNS event. Run the Boston Syncope Rule and tell me if he's high risk.”
Low-risk syncope discharge support
“Young healthy patient came in after fainting — no ACS symptoms, no conduction disease, no cardiac history concerns, no valvular disease, no family history of sudden death, vitals are normal and stable, no dehydration or bleeding, and no CNS event. Apply the Boston Syncope Rule to confirm she's low risk.”
Volume-depletion syncope with hematocrit concern
“My ED patient syncopized and has a hematocrit below 30, so the caller is flagging volume depletion. No other Boston Syncope criteria are positive — no ACS, no conduction disease, no cardiac history, no valvular disease, no family history of sudden death, normal vitals, no CNS event. What does the Boston rule say about her risk?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/boston_syncopeWhen to prefer
Use this endpoint when you need a fast, rule-based Boston Syncope Rule calculation for an adult ED patient and have already collected clinician-assigned binary flags for all eight Grossman 2007 criteria. Prefer this over San Francisco Syncope Rule, EGSYS, ROSE, or OESIL endpoints when the Boston rule is specifically required or when the clinical workflow follows Grossman 2007. Not appropriate for pediatric patients or as a standalone admission decision.
Side effects
- Missing any of the eight required boolean query parameters returns a validation error
- Non-boolean values for flag parameters cause a bad request error
- Network or payment authorization failure results in no response
- Caller misassigning flags (e.g. assuming the API interprets ECGs or examines the patient) leads to clinically incorrect results
