    Canadian Syncope Risk Score

    Predicts 30-day serious adverse events in patients presenting with syncope.

    INSTRUCTIONS

    Applicable to patients ≥16 years old presenting ≤24 hours of syncope. Do not use if: prolonged (>5 min) LOC, change in mental status from baseline, obvious witnessed seizure, major trauma, intoxication, language barrier, or head trauma causing LOC. This calculator is externally validated, according to data presented at the Society for Academic Emergency Medicine Annual Meeting 2018.

    When to Use
    Pearls/Pitfalls
    Why Use
    • Patients ≥16 years old presenting ≤24 hours of syncope.
    • Do not use in patients with any of the following:
      • Prolonged (>5 min) LOC.
      • Change in mental status from baseline.
      • Obvious witnessed seizure.
      • Major trauma requiring hospital admission.
      • Intoxication with alcohol or illicit drugs.
      • Language barrier.
      • Head trauma causing LOC.
    • Predicts risk of 30-day serious adverse events associated with syncope, defined as any of the following: death, arrhythmia, non-arrhythmic cardiac causes, or non-cardiac causes (see Evidence for full list).
    • In 2020, the CSRS was successfully validated (see Evidence, below).
    • Syncope is a common, often benign presenting complaint in emergency departments, that sometimes has life-threatening underlying causes. The Canadian Syncope Risk Score identifies patients with syncope who are at higher risk of adverse outcomes.
    • Can potentially avoid unnecessary investigation and/or admission.
