Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults over 18 years old who present to the emergency department within 24 hours of experiencing syncope.

Probably not a fit

Patients who do not meet the criteria for syncope or have conditions such as prolonged loss of consciousness or seizures may not benefit from this study.

What this trial studies

This clinical trial aims to implement the Canadian Syncope Risk Score (CSRS) in emergency departments across Canada to improve decision-making for patients presenting with syncope. The study will involve a stepped-wedge cluster randomized trial design, where 16 emergency department clusters will sequentially transition from usual care to the CSRS-based intervention over a total duration of 16 months. The primary focus is to assess the impact of this implementation on health resource utilization and patient outcomes, particularly in reducing unnecessary hospitalizations. The trial will also evaluate the effectiveness of knowledge translation strategies in enhancing the adoption of the CSRS recommendations in clinical practice.

Why it matters

Potential benefit: If successful, this approach could significantly reduce unnecessary hospitalizations for patients with syncope while ensuring that high-risk patients receive appropriate care.

How similar studies have gone: Previous studies have shown promise in implementing risk stratification tools in emergency settings, suggesting that this approach could be effective.

* Patients who had a serious underlying for the syncope identified during the index ED evaluation and those who were consulted to an inpatient service or hospitalized for reasons other than syncope workup (e.g., social reasons such as inability to cope at home, pain due to the fall, significant trauma).
