Abstract WP246: Acute Ischemic Stroke Patients With a Primary Language Other Than English Do Not Have Significantly Increased Door-to-Needle Times for Intravenous TPA
Background: Rapid administration of intravenous alteplase (IV tPA) leads to better outcomes, but language barriers have the potential to introduce delays and to hinder effective communication with patients and collateral historians during the acute evaluation.
Hypothesis: Acute ischemic stroke patients with a non-English primary language will have significantly longer door-to-needle times for IV tPA.
Methods: We abstracted information on primary language for all adults that received IV tPA for acute ischemic stroke in the emergency department of an academic referral center in San Francisco, CA, from February 2008 to May 2015. Approximately 38% of San Francisco residents speak a language other than English at home. Primary language was determined from the electronic medical record and was confirmed by reviewing specific documentation in subsequent speech therapy evaluations and admission notes. Age, sex, race, presenting NIHSS, aphasia as a presenting symptom, whether the patient was accompanied to the emergency department by a family member or caregiver, discharge disposition, and door-to-needle (DTN) administration time for IV tPA were abstracted from clinical records and quality improvement registries.
Results: A total of 237 patients received IV tPA for acute ischemic stroke in the emergency department during the study period. Median age was 76 years (IQR 64-86), 53% were female, and median DTN time was 62 minutes (IQR 48-86). A total of 34% of patients had a primary language other than English (20% Cantonese, 6% Russian, 3% Spanish). These patients were more likely to be older (median age 80 vs. 73 years, p = 0.001), to be accompanied by a family member or caregiver (80% vs. 59%, p = 0.003), and to have a higher NIHSS (median 9 vs. 11, p = 0.03), but DTN times were similar among English and non-English primary language speakers (median 62 vs. 62, p=0.88) and short-term outcomes were not significantly different (in-hospital mortality 9% English primary language vs 14% non-English primary language, p=0.27; discharge to home 43% vs 32%, p=0.16) .
Conclusions: At a center serving a multiethnic population, a patient’s primary language did not appear to predict DTN times for acute ischemic stroke.
