Comparison of stroke process measures and clinical outcomes between English and Non-English preferring patients.

Background: In the United States, limited English proficiency may reduce the quality of care and worsen outcomes after stroke. The aim was to compare stroke process measures and clinical outcomes between English preferring and non-English preferring stroke patients.

Methods/materials: This single-center retrospective cohort study evaluated patients from one United States hospital with acute ischemic stroke between July 2013 and June 2022. The primary outcomes were defect-free care, a composite of 7 stroke process measures, and independent ambulation at hospital discharge. Multivariate logistic regression models quantified the association between language preference and outcomes. Secondary outcomes included individual components of defect-free care, discharge modified Rankin scale, and discharge disposition.

Results: There were 4,030 patients with acute ischemic stroke identified, of which 2,965 were matched with language data from the electronic medical record. There were 373 non-English preferring patients, among which 76.9% preferred Spanish and 23.1% were non-English, non-Spanish preferring. In the multivariable model, there was no significant association between non-English preference and defect-free care (OR=0.64, 95% CI=0.26-1.59) or independent ambulation at discharge (OR=0.89, 95% CI=0.67-1.17). When compared to Spanish preferring patients, non-English, non-Spanish preferring patients had more severe strokes (P<0.001) but there was no difference in defect-free care or independent ambulation after adjustment.

Conclusion: Our results suggest that process and clinical outcomes are similar regardless of language preference; although, our data are limited by small numbers of non-English, non-Spanish preferring patients. Additional research is needed among this population.
