Practice variability in management of transient ischemic attacks.

To define practice patterns in the management of transient ischemic attacks (TIAs), we surveyed practicing neurologists attending an educational conference in San Francisco, evaluating management decisions in 2 TIA case vignettes. In a vignette describing a hemispheric TIA 1 day prior with ipsilateral bruit, 53% chose admission, 47% elected an outpatient work-up, 28% treated with intravenous heparin and 70% chose aspirin, reflecting the disagreement about medical management of carotid stenosis in the literature. There was more agreement in the second case, a posterior circulation TIA 1 day prior with atrial fibrillation, in which 84% chose hospital admission, 74% chose intravenous heparin and 90% treated with some form of anticoagulation. There are areas of important practice variability in the management of TIAs. Further research is justified to guide patient care decisions in TIA patients.
