Abstract
Background:
Race and ethnicity can have a major impact on the quality of care patients with acute ischemic stroke (AIS) receive. We sought to assess the impact of race and ethnicity on quality benchmarks of AIS therapy and clinical outcomes at a comprehensive stroke center (CSC).
Methods:
A retrospective analysis of AIS patients presenting to a CSC between 2015 to 2020 was performed. Data included demographics, NIH Stroke Scale scores, time to thrombolysis, discharge diabetic and hypertensive medications, length of stay (LOS), discharge functional status, 30-day readmission, and 30-day mortality. Quality benchmarks and outcomes were analyzed by the five most prevalent racial-ethnic groups including Non-Hispanic White (NHW), Hispanic, Black, Asian, Other and Unknown.
Results:
3,735 AIS patients were identified. NHW represented 53.3% (n=1992),Black 21.3% (n=797), Hispanic 10.4% (n=390), Asian 7.2% (n=267), Other 4.6% (n=170) and Unknown 3.2% (n=119). There were no significant differences in door to needle (P=0.93), door to puncture time (P=0.98), intravenous thrombolysis (P=0.32) and mechanical thrombectomy utilization (P=0.19) by race-ethnicity. In univariable analysis, there was a higher rate of 30-day mortality in Unknown 23.5% vs NHW 7.3% (P< 0.0001). A significantly (P>0.05) higher rate of 30-day readmission was noted in NHW 20.3% vs Black 15.7%, Hispanics 15.6%, Others 11.8% and Unknown 8.4%. Black 67.6%, Hispanic 64.9% and Unknown 80.5% had a significantly (P<0.05) higher rate of post stroke disability (mrs>2) vs NHW 60.3%. A significant difference (P<0.05) in LOS with Black patients staying 8.4, Hispanic 10.8, Asians 11.9 and Unknown 11.2 days vs NHW 7.7.Adjusting for age, sex, NIHSS and comorbidities, multivariable logistic regression continued to show differences in post stroke disability for Black (OR=1.40, P=0.003), Hispanic (OR=1.49, P=0.008) and Unknown (OR=2.03, P=0.016) vs NHW. Median LOS was 0.85 and 0.77 days longer for Asian and Hispanic (P=0.006, P=0.014) respectively vs NHW.
Conclusions:
Our analysis reveals persistent disparities in stroke outcomes, with Black and Hispanic patients suffering greater disability post stroke. Further investigation is needed to uncover how race-ethnicity mediates stroke care and outcomes.

Abstract
Background:
Language barriers can have a major impact on the quality of care that patients with acute ischemic stroke (AIS) receive. We sought to assess the impact of patient language on quality benchmarks of AIS therapy and clinical outcomes at a high-volume comprehensive stroke center (CSC).
Methods:
A retrospective analysis of AIS patients presenting to a CSC between 2015 to 2020 was performed. Data included demographics, NIH Stroke Scale scores (NIHSS), discharge diabetic and hypertensive medications, length of stay (LOS), discharge functional status, 30-day readmission, and 30-day mortality. Quality benchmarks and outcomes were analyzed by the five most prevalent primary languages including English, Spanish, Russian, Farsi, Korean and Other. All non-English speaking patients received medical interpretation via digital or in-person translation.
Results:
3,812 AIS patients were identified. English language represented 80.2% (n=3091), Spanish 7.6% (n=238), Russian 4.1% (n=184), Farsi 3.0% (n=129), Korean 1.5% (n=47) and Other 3.6% (n=122).There were no significant differences in the rate of intravenous thrombolysis (P=0.52), door-to-needle time (P=0.91), door-to-puncture time (P=0.85), LOS (P=0.089) and 30 day readmission (P=0.74) among groups. In univariable analysis, Spanish 74.7%, Korean 84.4%, Russian 73.4%, Farsi 78.2% and Other 70.0% had significantly (P< 0.05) higher rates of post stroke disability (mRS> 2) compared to the English group 60.7%. A higher rate of 30-day mortality was noted in the Korean 17.8% compared to the English group 7.3%. The Spanish group had a higher rate of mechanical thrombectomy than the English group (11.8 vs 6.5%, P=0.009). Adjusting for age, sex, NIHSS and comorbidities, multivariable logistic regression models for post stroke disability (mRS>2) continued to show significant differences with Spanish (OR=1.66, P=0.008) and Farsi (OR=1.89, P=0.017) vs English.
Conclusions:
Our analysis reveals persistent disparities in AIS outcomes by primary language, with patients with limited English proficiency suffering worse disability after AIS. The effect of communication barriers on outcomes of stroke care in the inpatient setting requires further evaluation to close this gap.
