“Clinical Question: Does the Canadian TIA Score perform better than the ABCD2 score in stratifying subsequent stroke risk in patients with TIAs?
Author Conclusion: “The Canadian TIA Score stratifies patients’ seven day risk for stroke, with or without carotid endarterectomy/carotid artery stenting, and is now ready for clinical use. Incorporating this validated risk estimate into management plans should improve early decision making at the index emergency visit regarding benefits of hospital admission, timing of investigations, and prioritization of specialist referral.”
Clinical Take Home Point: As they always do, Perry and colleagues have done an amazing job deriving and validating the Canadian TIA Score. This score is certainly better than ABCD2 and ABCD2i in risk stratification of patients with suspected TIAs. However, risk stratification is one thing, and the resources available, follow up available, and the health system in which one works may make risk stratification a moot point.”
