We previously reviewed the Sudbury Risk Score for Vertigo. It was initially published in:
Ohle R, et al. Development of a Clinical Risk Score to Risk Stratify for a Serious Cause of Vertigo in Patients Presenting to the Emergency Department. https://doi.org/10.1016/j.annemergmed.2024.06.003. Article in Press.
The aim of this study was “to prospectively assess the clinical characteristics of patients presenting with vertigo to the ED and to derive a clinical risk score to identify high- and low-risk patients for a serious cause of their vertigo.”
What They Did
This was a prospective multicenter cohort study, conducted in three Canadian Emergency Departments. It included adult patients ( > 17 yo) presenting with acute vertigo, dizziness, or imbalance.
What They Found
They concluded with a predictive score as below:
Probability of a serious cause (stroke, TIA, vertebral artery dissection, or brain tumor)
- 0% for a score of <5,
- 2.1% for a score of 5 to 8, and
- 41% for a score >8
