Racial, Socioeconomic, and Geographic Disparities in Acute Stroke Care in the United States: Miles to Go Before We Sleep

Introduction : Stroke is a leading cause of morbidity, mortality and healthcare spending in the United States. Acute management of ischemic stroke is time‐dependent and evidence suggests improved clinical outcomes for patients treated at designated certified stroke centers. There is an increasing trend among hospitals to obtain certification as designated stroke centers. A common source or integrated tool providing both information and location of all available stroke centers in the US irrespective of the certifying organization is not readily available. The objective of our research is to generate a comprehensive and interactive electronic resource with combined data on all geographically‐coded certified stroke centers to assist in pre‐hospital triage and study healthcare disparities in stroke including availability and access to acute stroke care by location and population. Methods : Data on stroke center certification was primarily obtained from each of the three main certifying organizations: The Joint Commission (TJC), Det Norske Veritas (DNV) and Healthcare Facilities Accreditation Program (HFAP). Geographic mapping of all stroke center locations was performed using the ArcGIS Pro application. The most current data on stroke centers is presented in an interactive electronic format and the information is frequently updated to represent newly certified centers. Utility of the tool and its analytics are shown. Role of the tool in improving pre‐hospital triage in the stroke systems of care, studying healthcare disparities and implications for public health policy are discussed. Results : Aggregate data analysis at the time of submission revealed 1,806 total certified stroke centers. TJC‐certified stroke centers represent the majority with 106 Acute Stroke Ready (ASR), 1,040 Primary Stroke Centers (PSCs), 49 Thrombectomy Capable Centers (TSCs) and 197 Comprehensive Stroke Centers (CSCs). A total of 341 DNV‐certified programs including 36 ASRs, 162 PSCs, 16 PSC Plus (thrombectomy capable) and 127 CSCs were identified. HFAP‐certified centers (75) include 16 ASRs, 49 PSCs, 2 TSCs and 8 CSCs. A preliminary map of all TJC‐certified CSCs and TSCs is shown in the figure (1). Geospatial analysis reveals distinct areas with currently limited access to certified stroke centers and currently, access to certified stroke centers is extremely limited to non‐existent in fe States (for example: Idaho, Montana, Wyoming, New Mexico and South Dakota). Conclusions : Stroke treatment and clinical outcomes are time‐dependent and prompt assessment and triage by EMS directly to appropriate designated stroke centers is therefore critical. A readily available electronic platform providing location and treatment capability for all nearby certified centers will enhance regional stroke systems of care, including enabling more rapid inter‐hospital transfers for advanced intervention. Identifying geographic areas of limited access to treatment can also help improve policy and prioritize the creation of a more equitable and well‐distributed network of stroke care in the United States.

Background: Critical access hospitals (CAH) are the first point of stroke care in many rural regions of the United States (US). The Illinois Critical Access Hospital Network (ICAHN), a network of 51 CAH in Illinois, began a quality improvement program to address acute stroke care in 2009. We evaluated the performance on several metrics in acute stroke care at CAH between 2009 and 2011. Methods: Currently, 28 of 51 CAHs in Illinois currently participate in the American Heart Association’s Get With The Guidelines - Stroke (GWTG-S) registry for quality improvement. The GWTG-S registry captured elements including demographics, diagnosis, times of arrival, imaging completion, and intravenous tissue plasminogen activator (IV tPA) administration, and final discharge disposition. We analyzed the change in percent of stroke patients receiving tPA, door-to-needle (DTN) time, and proportion of total stroke patients admitted versus transferred to another facility over the 3 years. Fisher’s exact and Mann-Whitney tests were used as appropriate. Results: In the baseline assessment (2009), there were 111 strokes from 8 sites which grew to 12 sites and 305 strokes in year 1 (2010) and 14 sites and 328 strokes in year 3 (2011). The rate of tPA use for ischemic stroke was 2.2% in 2009, 4.0% in 2010, and 6.2% in 2011 (P=0.20). EMS arrival (41.1%), EMS pre-notification (82.6%), door-to-CT times (median 35 minutes; 34.6% < 25 minutes), and DTN times (average 93 minutes; 13.3% DTN time < 60 minutes) were not different over time. The rate of transfer from CAH to another hospital (51.3%) was constant. Every patient that received tPA except 1 (96.9%) was transferred (drip-ship) for post-tPA care. Conclusions: Improving acute stroke care at CAHs is feasible and represents a significant opportunity to increase tPA utilization in rural areas. As stroke systems develop, it is vital that CAHs be included in quality improvement efforts. The ICAHN stroke collaborative provided the opportunity to coordinate resources, share best practices, participate in targeted educational programming, and utilize data for performance improvement through the funded GWTG-S registry.

Introduction: Stroke is a leading cause of disability in the United States. Disparities in stroke care between metropolitan and rural areas have long been recognized. Access to high-level timely stroke expertise improves outcomes, but in rural areas this is limited by sparse availability of stroke specialists. Since 2006, the Nebraska Stroke Advisory Council, a statewide coalition of stroke experts and stakeholders, began implementing strategies to improve stroke care. In 2016, the Nebraska legislature approved Bill 722, mandating the development of stroke systems of care. In 2018, the AHA and the Helmsley Charitable Trust launched Mission: Lifeline Stroke, a coordinated 3-year program to enhance stroke systems of care in Nebraska. Purpose: To assess advances in acute stroke care in Nebraska after implementing a statewide stroke system of care focused on rural areas. Methods: The Council joined with AHA to expand public and professional stroke education offerings including workshops, conferences, and EMS trainings. They developed state specific treatment guidelines and created educational reinforcement materials. From 2016 to 2019 Get With The Guidelines® (GWTG) was used for stroke data collection and quality improvement in Nebraska. GWTG participating hospitals expanded from 7 to 40 sites (21 critical access). Results: The number of stroke and Transient Ischemic Attack cases reported more than doubled from 2016 to 2019 (1848 to 3987 cases). The door to CT initiated in < 25 minutes improved by 13%. IV alteplase therapy gains included: utilization increased from 8.7% to 11.3%; median door to drug time reduced from 54 to 42 minutes; and door to drug within 60 minutes of arrival increased from 67% to 80.4%.The number of alteplase monitored patients doubled and mechanical thrombectomy cases increased from 77 in 2017 to 138 in 2019. Conclusion: Implementation of strategies in Nebraska, with an emphasis on rural critical access hospitals, led to significant improvements in acute stroke care. This work represents the authors’ independent analysis of local or multicenter data gathered using the AHA Get With The Guidelines® Patient Management Tool but is not an analysis of the national GWTG dataset and does not represent findings from the AHA GWTG National Program

Geographic Disparities

Stroke is the second-leading cause of death and a major cause of disability worldwide. The majority of strokes are ischaemic, and effective therapy to achieve reperfusion includes intravenous thrombolysis and, for proximal large vessel occlusion strokes, endovascular mechanical thrombectomy (MT). There has been a paradigm shift in acute stroke care, driven by a series of randomised controlled trials demonstrating that timely reperfusion with MT results in superior outcomes compared to intravenous thrombolysis in patients with large vessel occlusion strokes. There are significant geographic disparities in delivering acute stroke care because of the maldistribution of neurointerventional specialists. There are now several case series demonstrating the feasibility and safety of first medical contact MT by carotid stent-capable interventional cardiologists and noninvasive neurologists working on stroke teams, which is a solution to the uneven distribution of neurointerventionalists and allows stroke interventions to be delivered in local communities.

Get With The Guidelines

Background and Purpose: The coronavirus disease 2019 (COVID-19) pandemic has created challenges in the delivery of acute stroke care. In this study, we analyze the characteristics, evaluation, treatment, and in-hospital outcomes of patients presenting with acute ischemic stroke (AIS) pre-COVID-19 and during COVID-19. Methods: Get With The Guidelines-Stroke is a national registry of adults with stroke in the United States. Using this registry, we identified patients with a diagnosis of AIS before (n=39 113; November 1, 2019–February 3, 2020) and after (n=41 971; February 4, 2020–June 29, 2020) the first reported case of COVID-19 in the registry. Characteristics, treatment patterns, quality metrics, and in-hospital outcomes were compared between the 2 groups. Results: Stroke presentations decreased by an average of 15.3% per week in the during COVID-19 time period when compared with similar months in 2019. Compared with patients with AIS in the pre-COVID-19 era, patients in the COVID-19 time period had similar rates of intravenous alteplase and endovascular therapy, and similar door to computed tomography, door to needle, and door to endovascular therapy times. In adjusted models, inpatient mortality was similar between those presenting with AIS pre-COVID-19 and during COVID-19 (4.8% versus 5.2%; odds ratio, 1.05 [95% CI, 0.97–1.13]). Conclusions: Among hospitals participating in Get With The Guidelines-Stroke, patients presenting with AIS during COVID-19 received, with few exceptions, similar quality care and experienced similar risk-adjusted outcomes when compared with patients with AIS presenting pre-COVID-19. These findings demonstrate that stroke care in the United States remains robust during the COVID-19 pandemic.

Iv Tpa

Background: Only 5% of ischemic stroke (IS) patients receive IV tPA and less than 1% receive endovascular therapy (ET). Prior work has described access to Primary Stroke Centers (PSC). We describe access of the US population to all facilities that provide IV tPA or ET for IS. Methods: We used US demographic data and IV tPA and ET rates in the 2011 Medicare Provider and Analysis Review (MEDPAR), a claims-based dataset that contains fee-for-service Medicare-eligible inpatient hospital discharges in the US. ICD-9 codes 433.xx, 434.xx and 436 identified IS cases. ICD-9 code 99.10 defined IV tPA treatment. Among IS cases, hospitals that gave any IV tPA were considered IV capable. ET was defined by ICD-9 code 39.74. Hospitals that performed any ET in IS cases were considered endovascular capable. PSCs were defined as hospitals certified as such by the Joint Commission in 2010. We estimated ambulance response times using arc-GIS’s network analyst and helicopter transport times using validated models. Population access to care was determined by summing the population contained within travelsheds that could reach capable hospitals within 60minutes. Results: Of 370351 IS primary diagnosis discharges, 14926 (4%) received IV tPA and 1889 (0.5%) had ET. By ground, 81% percent of the US population had access to IV capable hospitals within 60minutes, 66% had access to PSCs and 56% had access to ET capable hospitals. By air, 97% percent had access to IV capable hospitals within 60minutes, 91% had access to PSCs and 85% had access to ET hospitals. The Figure shows 60 (yellow) and 120 minute (green) access to IV rt-PA capable hospitals. Conclusion: Most of the US population has geographic access to acute stroke care, but treatment rates remain extremely low. Given our definitions of capability, actual access may be less than described. To optimize US stroke care systems and increase the use of acute therapies, pre- and inhospital interventions to overcome barriers in access to acute stroke care are needed.
