P211 Background: Previous studies have suggested that  carotid ultrasound (CUS) tests are less likely to be utilized in  African American (AA) patients with stroke or TIA compared to whites  (Stroke 1999; 30: 1350). Whether the localization of the  cerebral ischemic event or the stroke subtype influences the ordering  of carotid imaging tests is unclear.Objective: To determine the  patterns of CUS utilization in a large cohort of AA stroke patients.Methods: The African American Antiplatelet Stroke Prevention  Study database was used for this analysis. Stroke localization was  evaluated and stroke subtype was also recorded. CUS utilization was  analyzed for the various stroke subgroups and statistical significance  was determined by chi square testing. To ensure that site variation in  CUS use did not explain any observed differences, the Mantel-Haenszel  test was applied using the sites as strata.Results: As of  7/99, 1087 patients were entered in the database. In 67 patients, the  stroke localization was uncertain, leaving 1020 patients for analysis.  Using the stroke localization and subtype information available, 479  patients were classified as carotid (CAR) territory, 278 as  vertebrobasilar (VB), 139 as indeterminate (IND), and 124 as both  territories (BOTH). CAR strokes were further subdivided into lacunar  and nonlacunar events. There was a statistically significant difference  in the CUS utilization among the five groups. CUS exams were obtained  in 56% of VB patients, compared to 75 to 81% in the other groups  (p&lt;0.001). For the other groups, CUS was performed in CAR nonlacunar  (75.6%), CAR lacunar (76.5%), IND (80.2%), and BOTH (80.8%). There  was no difference in CUS use in patients with a lacunar vs. nonlacunar  presentation (p=0.816). An adjustment stratified by center among sites  with at least 20 patients produced the same statistical significance  (p&lt;0.001).Conclusions: There appears to be an  underutilization of CUS exams in AA patients with carotid territory  strokes, especially for patients with a nonlacunar mechanism. This may  lead to decreased performance of potentially valuable stroke prevention  measures such as carotid endarterectomy in symptomatic AA  patients.

Are African American stroke patients receiving appropriate carotid ultrasound exams?
