Disparities and Trends in Door-to-Needle Time: The FL-PR CReSD Study (Florida-Puerto Rico Collaboration to Reduce Stroke Disparities).
2017
Background and Purpose—In the United States, about half of acute ischemic stroke patients treated with tPA (tissue-type plasminogen activator) receive treatment within 60 minutes of hospital arrival. We aimed to determine the proportion of patients receiving tPA within 60 minutes (door-to-needle time [DTNT] ≤60) and 45 minutes (DTNT ≤45) of hospital arrival by race/ethnicity and sex and to identify temporal trends in DTNT ≤60 and DTNT ≤45. Methods—Among 65 654 acute ischemic stroke admissions in the National Institute of Neurological Disorders and Stroke-funded FL-PR CReSD study (Florida-Puerto Rico Collaboration to Reduce Stroke Disparities) from 2010 to 2015, we included 6181 intravenous tPA-treated cases (9.4%). Generalized estimating equations were used to determine predictors of DTNT ≤60 and DTNT ≤45. Results—DTNT ≤60 was achieved in 42% and DTNT ≤45 in 18% of cases. After adjustment, women less likely received DTNT ≤60 (odds ratio, 0.81; 95% confidence interval, 0.72–0.92) and DTNT ≤45 (odds ratio, ...
