CSRS Implementation - A Pilot Study

Syncope is a common reason for emergency department (ED) presentation. While often benign, some patients have serious and life-threatening underlying causes, both cardiac and non-cardiac, which may or may not be apparent at the time of the initial ED assessment. Identifying which patients will benefit from further investigation, ongoing monitoring and/or hospital admission is essential to reduce both adverse outcomes and the high costs. Our group has spent over a decade developing the evidence base for a risk stratification tool directed at optimizing the accuracy of ED decisions: the Canadian Syncope Risk Score (CSRS). This tool is now ready for the final phase of its introduction into clinical practice, namely a robust, multicentre implementation trial of the CSRS based practice recommendations to demonstrate its real-world effectiveness. Prior to the launch of the large-scale implementation trial, a pilot study to assess primarily the feasibility and secondarily the effectiveness is needed.
