Stroke Hospital Characteristics in the Florida-Puerto Rico Collaboration to Reduce Stroke Disparities Study.

OBJECTIVES: Although disparities in stroke care and outcomes have been well documented nationally, state-based registries to monitor acute stroke care in Florida (FL) and Puerto Rico (PR) have not been established. The FL-PR Collaboration to Reduce Stroke Disparities (CReSD) was developed to evaluate race-ethnicity and regional disparities in stroke care performance. The objective of this study was to assess and compare hospital characteristics within a large quality improvement registry to identify characteristics associated with better outcomes for acute ischemic stroke care. METHODS: Trained personnel from 78 FL-PR CReSD hospitals (69 FL, 9 PR) completed a 50-item survey assessing institutional characteristics across seven domains: acute stroke care resource availability, emergency medical services integration, stroke center certification, data collection and use, quality improvement processes, FL-PR CReSD recruitment incentives, and hospital infrastructure. RESULTS: The rate of survey completion was 100%. Differences were observed both within FL and between FL and PR. Years participating in Get With The Guidelines-Stroke (8.9 ± 2.6 years FL vs 4.8 ± 2.4 years PR, P < 0.0001) and proportion of hospitals with any stroke center certification (94.2% FL vs 11.1% PR, P < 0.0001) showed the largest variations. Smaller hospital size, fewer years in Get With The Guidelines-Stroke, and lack of stroke center designation and acute stroke care practice implementation may contribute to poorer outcomes. CONCLUSIONS: Results from our survey indicated variability in hospital- and system-level characteristics in stroke care across hospitals in Florida and Puerto Rico. Identification of these variations, which may explain potential disparities, can help clinicians understand gaps in stroke care and outcomes and targeted interventions to reduce identified disparities can be implemented.

Racial-Ethnic Disparities in Acute Stroke Care in the Florida-Puerto Rico Collaboration to Reduce Stroke Disparities Study.

BACKGROUND: Racial-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 RESULTS: Seventy-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%). CONCLUSIONS: Racial-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.
