Objective

Background BACKGROUND: We examined associations between age, gender, and race-ethnicity and use of acute reperfusion therapy for acute ischemic stroke (AIS) in Cook County, Illinois.

Design/Methods DESIGN/METHODS: Using the Illinois Hospital Association CompData®, we identified patients hospitalized for AIS at Cook County's primary stroke centers (PSCs) between September 2008 and August 2011. We assessed use of RT by ICD-9 procedure codes (tPA: 99.10 and V45.88; mechanical embolectomy: 37.94). Patients were classified by age: <55 y, 55-65 y, 65-75 y, 75-85 y, and >85 y. Within combined age, race/ethnicity and gender subgroups, we assessed use of RT.

Results RESULTS: There were 18,474 AIS discharges and use of RT was 5.8%. RT differed by race (B: 4.8% vs. W: 6.7% and H: 6.2%; p<0.001), age groups(< 55 y: 7.7% vs. other groups: 5.5%: p<0.001) but was similar by gender (women: 5.9% vs. men: 5.7%, p=0.723). Among women, black and Hispanics 75-85 y were less likely to receive RT than whites (B: 2.9% and H: 2.5% vs. W: 8.1%, p<0.001). Among men, blacks < 55 y were less likely to receive RT (B: 6.3% vs. H: 10.0% and W: 9.6%; p=0.049) and blacks and Hispanics aged 65-75 y were less likely to receive RT than whites (B: 3.3% and H: 4.1% vs. W: 6.5%; p=0.017).

Conclusions CONCLUSIONS: Age-related differences in stroke RT were seen in specific race/ethnic and gender subgroups. Compared to whites < 55 y and 65-75 y, black and Hispanic men were less likely to receive RT while black and Hispanic women in the 75-85 y age group less likely to receive RT than whites. Our data suggest that race/ethnic barriers for acute stroke therapy may differ by age and gender subgroups.
