BackgroundRacial‐ethnic disparities in acute stroke care can contribute to inequality in stroke outcomes. We examined race‐ethnic disparities in acute stroke performance metrics in a voluntary stroke registry among Florida and Puerto Rico Get With the Guidelines‐Stroke hospitals.Methods and ResultsSeventy‐five sites in the Florida Puerto Rico Stroke Registry (66 Florida and 9 Puerto Rico) recorded 58 864 ischemic stroke cases (2010–2014). Logistic regression models examined racial‐ethnic differences in acute stroke performance measures and defect‐free care (intravenous tissue plasminogen activator treatment, in‐hospital antithrombotic therapy, deep vein thrombosis prophylaxis, discharge antithrombotic therapy, appropriate anticoagulation therapy, statin use, smoking cessation counseling) and temporal trends. Among ischemic stroke cases, 63% were non‐Hispanic white (NHW), 18% were non‐Hispanic black (NHB), 14% were Hispanic living in Florida, and 6% were Hispanic living in Puerto Rico. NHW patients were the oldest, followed by Hispanics, and NHBs. Defect‐free care was greatest among NHBs (81%), followed by NHWs (79%) and Florida Hispanics (79%), then Puerto Rico Hispanics (57%) (P<0.0001). Puerto Rico Hispanics were less likely than Florida whites to meet any stroke care performance metric other than anticoagulation. Defect‐free care improved for all groups during 2010–2014, but the disparity in Puerto Rico persisted (2010: NHWs=63%, NHBs=65%, Florida Hispanics=59%, Puerto Rico Hispanics=31%; 2014: NHWs=93%, NHBs=94%, Florida Hispanics=94%, Puerto Rico Hispanics=63%).ConclusionsRacial‐ethnic/geographic disparities were observed for acute stroke care performance metrics. Adoption of a quality improvement program improved stroke care from 2010 to 2014 in Puerto Rico and all Florida racial‐ethnic groups. However, stroke care quality delivered in Puerto Rico is lower than in Florida. Sustained support of evidence‐based acute stroke quality improvement programs is required to improve stroke care and minimize racial‐ethnic disparities, particularly in resource‐strained Puerto Rico.
Background: Minor stroke/TIA is the most common cause for thrombolysis exclusion in patients acutely presenting to the hospital. Thrombolysis administration in this subgroup is highly variable amongst different clinicians and institutions. We aim to study the predictors of thrombolysis in patients with mild ischemic stroke in the FL-PR CReSD Study. Methods: 73,712 patients with ischemic stroke/TIA were prospectively enrolled from January 2010 to April 2015. We included 7,746 patients who had persistent neurological symptoms with NIHSS score ≤5 and arrived within 4 hours of symptom onset. Multilevel logistic regression analysis was used to identify independent predictors of thrombolysis in the subgroup of patients without contraindications to thrombolysis Results: 6,826 patients (25% final diagnosis TIA, 75% minor stroke) were included (mean age=70±14 years), 52.7% male, 70.3% white, 13% black, 16.7% Hispanic, median NIHSS=2 (IQR=1,4). Patients who received thrombolysis (N=1281, 18.7%) were younger (67 vs. 70.7 years, P<0.001), had less vascular risk factors (HTN, DM, dyslipidemia), lower risk of prior vascular disease (MI, PVD, previous stroke) and had a higher presenting median NIHSS score (4 vs. 2, P<0.0001). In the multivariable analysis, younger age (OR 1.02, 95% CI 1.02-1.03, P<0.0001), white or Hispanic vs. black (OR 1.2, 95% CI 1.04-1.37, P=0.0097), early hospital arrival (unit change in 30 min.) (OR 1.26, 95% CI 1.21-1.31, P<0.0001), arrival by EMS (OR 1.28, 95% CI 1.08-1.49, P<0.0001), higher NIHSS score (OR 1.96, 95% CI 1.87-2.06, P<0.0001), altered level of consciousness (OR 1.43, 95% CI 1.11-1.85, P=0.0062) and aphasia at presentation (OR 1.34, 95% CI 1.13-1.58, P=0.0008) were independent predictors of thrombolysis administration. Conclusion: Minor acutely presenting stroke patients were more likely to receive thrombolysis if they were young, white or Hispanic, and arrived early to the hospital with more severe neurological presentation specifically aphasia and altered level of consciousness. Identification of predictors of thrombolysis utilization is important in the design of educational programs and randomized trials to increase the use of thrombolysis for minor stroke.
Mild acutely presenting stroke patients are more likely to receive thrombolysis if they are young, white, or Hispanic and arrive early to the hospital with more severe neurological presentation. Identification of predictors of thrombolysis is important in design of future studies to assess the use of thrombolysis for mild stroke.
