This research, posted in JAMA, looked to validate the Canadian Syncope Risk Score (CSRS), and its ability to help in decision-making for emergency department patients with syncope based on short-term serious outcomes. This prospective cohort study, comprising of 3,819 patients across 9 large emergency departments across Canada categorized patients from very-low to high-risk for the potential of a severe adverse event happening within 30-days of presenting to the ED. Categories were assigned based on a points system that accounted for clinical evaluation, diagnostic investigation, and diagnosis in the emergency department and from there, patients would be worked-up and closely monitored accordingly, either as outpatient or as an admitted patient. Their results showed that less than 1% of very-low-risk and low-risk patients, approximately 20% of high-risk patients, and 50% of very-high-risk CSRS patients experienced 30-day serious outcomes. Such strong risk classification offers short-term prognostic information to clinicians that may be translated into meaningful clinical management options.
