OESIL Score for Syncope
Why Use
Provides a simple risk stratification tool to predict 1-year all-cause mortality after a syncopal episode, helping to identify patients at higher risk who may need a more aggressive evaluation and treatment. Assists ED disposition decisions (admission vs. discharge) and potentially avoids unnecessary hospitalizations for low-risk patients.
When to Use
Use in the evaluation of adult patients presenting with syncope in the emergency department (ED). Particularly useful for risk stratification when the etiology of syncope is unclear after initial assessment.
Formula
Pearls / Pitfalls
Not appropriate for use in patients with significant underlying pathology and does not differentiate between specific causes of syncope (e.g., cardiac vs. neurogenic). Designed to be used at the time of initial presentation to the ED; results may not be reliable if applied in other clinical settings or situations. Developed and validated in patients aged ≥12 years. The derivation study excluded patients with known seizure disorders, those presenting with presyncope, dizziness, or vertigo, and those without a clear loss of consciousness.
Management
Low risk (score 0–1): Consider further outpatient evaluation and follow-up. Provide patient education on warning signs and when to return to the ED. Intermediate to high risk (score ≥2): Consider hospital admission for further monitoring and investigation (e.g., telemetry, echocardiography). Initiate consultations with cardiology or neurology as needed.
Advice
This tool complements, but does not replace, clinical judgment, a careful history, and a thorough evaluation of syncope patients in the ED.
