Five percent of transient ischemic attack (TIA) patients have a subsequent stroke within 7 days. The Canadian TIA Score uses clinical findings to calculate the subsequent stroke risk within 7 days. Our objectives were to assess 1) anticipated use; 2) component face validity; 3) risk strata for stroke within 7 days; and 4) actions required, for a given risk for subsequent stroke.    Methods  After a rigorous development process, a survey questionnaire was administered to a random sample of 300 emergency physicians selected from those registered in a national medical directory. The surveys were distributed using a modified Dillman technique.    Results  From a total of 271 eligible surveys, we received 131 (48.3%) completed surveys; 96.2% of emergency physicians would use a validated Canadian TIA Score; 8 of 13 components comprising the Canadian TIA Score were rated as  Very Important  or  Important  by survey respondents. Risk categories for subsequent stroke were defined as minimal-risk:   10% risk of subsequent stroke within 7 days.    Conclusion  A validated Canadian TIA Score will likely be used by emergency physicians. Most components of the TIA Score have high face validity. Risk strata are definable, which may allow physicians to determine immediate actions, based on subsequent stroke risk, in the emergency department.
