Is the Canadian Syncope Risk Score a valid clinical prediction tool for use in the emergency department?

BEEM Bottom Line

Why is this study important?

Syncope is a common emergency department (ED) presentation but there is a need for robust evidence to guide risk stratification for serious outcomes. This study aimed to prospectively validate the Canadian Syncope Risk Score (CSRS) to predict which patients were at risk of a serious outcome within 30 days of the index ED visit as well as to determine the patient’s immediate disposition, i.e., discharge home or admit to hospital. If validated, the use of CSRS will be able to improve patient safety and health care efficiency.

Which, if any, threats to validity are most likely to have an impact on the results and how?
