Introduction: Diffusion weighted MR imaging (DWI) is the most accurate method to confirm or exclude acute ischemic stroke, however due to logistics is not widely used in the emergent setting. While many patients with stroke symptoms will get an MRI during their hospitalization, it may occur only after hours of care in the ER or after admission. Hypothesis: Providing emergent MR imaging in Stroke Code patients avoids unnecessary admission and associated costs for work-up of stroke mimics which otherwise would not be rapidly identified. Methods: IRB-approved retrospective review of the first year of expedited acute stroke MR imaging availability at a TJC Comprehensive Stroke Center. Imaging included immediate non-contrast head CT on arrival with CT Angiography at discretion of Stroke Code Leader. Emergent MR was then performed in patients without MRI contraindications who had unclear diagnosis, or to clarify extent of infarct. Demographic, clinical and imaging data were analyzed with time from triage to imaging, tPA decision, and discharge. Results: MRI was performed prospectively in 68/456 patients presenting with possible acute stroke symptoms from 7/1/2014-7/1/2015 (44 male, 26 female, age 60+/-15 years). Symptom onset was within 3 hours in 34 (49%), 3-6 hours in 12 (17%) and >6 hours or awoke with symptoms in 22 (31%); NIHSS of 4 or less in 40 (59%). Median time from arrival to completion of non-contrast head CT was 16 minutes; median time from CT imaging to completion of DWI was 39 minutes. Twenty-nine patients were discharged directly from the ER after MRI, with median ER stay of 5 hours, 15 minutes. Conclusions: Through multi-departmental collaboration, expediting MR imaging in the setting of acute stroke evaluation can avoid unnecessarily prolonged ER observation and admission in patients with stroke mimics.

Background: It is unknown if improvements in ischemic stroke (IS) outcomes reported after cerebral reperfusion therapies (CRT) in developed countries are also applicable to the “real world” scenario of low and middle-income countries. We aimed to measure the long-term outcomes of severe IS treated or not with CRT in Brazil. Methods: Patients from a stroke center of a state-run hospital were included. We compared the survival probability and functional status at 3 and 12 months in patients with severe IS treated or not with CRT. From 2010 to 2011, we performed intravenous reperfusion when patients arrived within 4.5 h time-window (IVT group) and after 2011, mechanical thrombectomy (MT) combined or not with intravenous alteplase (IAT group). Those who arrived >4.5 h in 2010-2011 and >6 h in 2012-2017 did not undergo CRT (NCRT group). Results: From 2010 to 2017, we registered 917 patients: 74% (677/917) in the NCRT group, 19% (178/917) in the IVT group and 7% (62/917) in the IAT group. Compared to the NCRT group, IVT patients had a 28% higher (HR: 0.72; 95% CI 0.53-0.96) 3-month adjusted probability of survival and risk of functional dependence was 19% lower (adjusted RR: 0.81; 95% CI 0.73-0.91). For those who underwent MT, the adjusted probability of survival was 59 % higher (HR: 0.41; 95% CI 0.21-0.77) and the risk of functional dependence was 21% lower (adjusted RR: 0.79; 95% CI 0.66-094). These outcomes remained significantly better throughout the first year. Conclusion: CRT led to better outcomes in patients with severe IS in Brazil.

Abstract Purpose Mechanical thrombectomy (MT) is the first-line treatment in acute stroke patients presenting with large vessel occlusion (LVO). The efficacy of intravenous thrombolysis (IVT) prior to MT is being contested. The objective of this study was to evaluate the efficacy of MT without IVT in patients with no contraindications to IVT presenting directly to a tertiary stroke center with acute anterior circulation LVO. Materials and Methods We collected the data of 106 acute stroke patients who underwent MT in a single high-volume stroke center. Patients with anterior circulation LVO eligible for IVT and directly admitted to our institution who subsequently underwent MT were included. We recorded baseline clinical, laboratory, procedural, and imaging variables and technical, imaging, and clinical outcomes. The effect of intravenous thrombolysis on 3-month clinical outcome (mRS) was analyzed with univariate tests and binary and ordinal logistic regression analysis. Results Fifty-eight out of the 106 patients received IVT + MT. These patients had 2.6-fold higher odds of poorer clinical outcome in mRS shift analysis (p = 0.01) compared to MT-only patients who had excellent 3-month clinical outcome (mRS 0–1) three times more often (p = 0.009). There were no significant differences between the groups in process times, mTICI, or number of hemorrhagic complications. A trend of less distal embolization and higher number of device passes was observed among the MT-only patients. Conclusions MT without prior IVT was associated with an improved overall three-month clinical outcome in acute anterior circulation LVO patients.

Clinical Care Pathway

Background: We review our initial experience of India’s and Asia’s first mobile stroke unit (MSU) following the completion of its first year of operation. We outline the clinical care pathway integrating the MSU services using a case example taking readers along our clinical care workflow while highlighting the challenges faced in organizing and optimizing such services in India. Methods: Retrospective review of data collected for all patients from March 2018 to February 2019 transported and treated within the MSU during the first year of its operation. Recent case example is reviewed highlighting complete comprehensive acute clinical care pathway from prehospital MSU services to advanced endovascular treatment with focus on challenges faced in developing nation for stroke care. Results: The MSU was dispatched and utilized for 14 patients with clinical symptoms of acute stroke. These patients were predominantly males (64%) with median age of 59 years. Ischemic stroke was seen in 7 patients, hemorrhagic in 6, and 1 patient was classified as stroke mimic. Intravenous tissue plasminogen activator was administered to 3 patients within MSU. Most of the patients’ treatment was initiated within 2 h of symptom onset and with the median time of patient contact (rendezvous) following stroke being 55 mins. Conclusion: Retrospective review of Asia’s first MSU reveals its proof of concept in India. Although the number of patients availing treatment in MSU is low as compared to elsewhere in the world, increased public awareness with active government support including subsidizing treatment costs could accelerate development of optimal prehospital acute stroke care policy in India.

Background and purpose: Prediction of swallowing function in dysphagic patients with acute stroke is indispensable for discussing percutaneous endoscopic gastrostomy (PEG) placement. We performed a retrospective study using database of a large number of acute ischemic stroke patients to clarify predictors for acquisition of oral intake in chronic phase. Methods: A total 4,972 consecutive acute stroke patients were admitted to our stroke center during 8.5 years; a questionnaire was sent to all the survivors after 3 months of onset. We investigated nutritional access after 3 months of onset in 588 patients who could not eat orally 10 days after admission, and analyzed predictive factors for their acquisition of oral intake. Continuous variables were dichotomized to identify the most sensitive predictors; the cutoff values were investigated by receiver operating characteristics curve analysis. Results: Out of 588 dysphagic patients, 75 died during the 3 months, and 143 (28%) of the residual 513 achieved oral intake after 3 months. In logistic-regression models, age ≤80 years, absence of hyperlipidemia, absence of atrial fibrillation, modified Rankin Scale score 0 before onset, and low National Institutes of Health Stroke Scale (NIHSS) score independently predicted oral intake 3 months after onset. From two different model analyses, NIHSS score ≤17 on day 10 (OR 3.63, 95% CI 2.37-5.56) was found to be a stronger predictor for oral intake than NIHSS score ≤17 on admission (OR 2.34, 95% CI 1.52-3.59). At 3 months, 17/143 (12%) patients with oral intake were living at home, while only 1/370 (0.3%) patients without oral intake were. Conclusion: A quarter of dysphagic patients with acute stroke obtained oral intake 3 months after onset. Clinicians should be cautious about PEG placement for stroke patients with severe dysphagia who were independent prior to the stroke, aged ≤80 years, and show NIHSS score ≤17 on day 10, because their swallowing dysfunction may improve in a few months.

Aims: In 2011, the VA released the Acute Ischemic Stroke (AIS) Directive which mandated reorganization of acute stroke care, including self-designation as Primary (P), Limited Hours (LH), or Supporting (S) stroke center. We conducted interviews across stroke centers to understand barriers and facilitators faced in response. Methods: The final sample included 38 (84% invited) facilities: 9 P, 24 LH, and 5 S facilities. In total, 107 persons were interviewed including ED Chiefs, Chiefs of Neurology, ED Nurse Managers/Nurses and other staff. Semi-structured interviews were based on the AIS Directive. Completed interviews were transcribed and analyzed using Nvivo 10. Results: Barriers reported were a lack of personnel assigned to coordinate the facility response to the directive. Data collection and lack of staff were likewise commonly reported as barriers. For thrombolysis measures, the low number of eligible Veterans was another major barrier. LH and S facilities reported some unique barriers: access to radiology and neurology services; EMS diverting stroke patients to nearby stroke centers, maintaining staff competency, and a lack of stroke clinical champions. Some solutions applied included cross training X-ray technicians to provide head CT coverage, developing stroke order sets and templates, and staff training. Larger facilities added a stroke code pager system and improved upon its use, and established ED nurses to become first alerts for an acute stroke patient. LH and S facilities also responded by attempting to secure additional services and by establishing formal transfer agreements to improve Veteran tPA access. Conclusions: The AIS Directive brought focused attention to reorganizing and improving stroke care across a range of facility types. Larger VA facilities tended to follow established practices for organizing stroke care, but the unique LH designation presented challenges to consistently organize systems. Since Veterans have financial interest in presenting to a VA facility, ongoing work to organize VA care and to improve access to thrombolysis at smaller VA facilities is needed. This protocol was supported by Genentech Inc. Protocol ML 28238, VA HSRD QUERI Rapid Response Project 11-374, and the VA Stroke QUERI Center.

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.

Anticoagulant use, such as heparin, is usually contraindicated in acute stroke patients. We present a study of patients, who were treated with intravenous heparin after a stroke that were also found to have an intraluminal thrombus. Prior studies imply that recanalization is achieved with heparin; however heparin should only prevent thrombus propagation. Therefore it is unclear whether and how IV heparin can achieve recanalization of intraluminal thrombi in acute stroke patients. A retrospective review of all acute stroke patients from a single stroke center who received a therapeutic IV heparin infusion from 5/2006 to 9/2011 were included in the study. We compared patients who had complete/partial recanalization and/or improved flow versus those that did not, with both these groups on a standard intravenous heparin infusion protocol. Demographic data was compared between the groups. Average partial thromboplastin time (PTT) during heparin infusion, time between computed tomography angiographies (CTAs), time from stroke onset to receiving IV heparin, and vessel occluded were also compared between groups. Forty-one patients (19 female, 22 male) were included in the study with a total of 55 vessels (either carotid, middle cerebral artery, anterior cerebral artery, posterior cerebral artery/posterior circulation) having intraluminal thrombi; 31 patients had 41 vessels with either partial or complete recanalization of effected vessels, while 10 patients had 14 vessels that did not have at least one vessel recanalize while on heparin. Using t-test we noted that the average PTT between the vessels that had partial/complete recanalization group (61.74) and non-recanalization group (66.30) was not statistical significantly different (P=0.37).The average time in days on heparin between vascular imaging studies (CTA/conventional angiogram) in the group of vessels with partial/complete recanalization (7.12 days) and the ones with no change (6.11 days) was not significantly different between the two groups (P=0.59). Patient’s vessels receiving heparin for &lt;24 hours <em>versus</em> those &gt;24 hours did not significantly differ either (P=0.17). This study compares patient characteristics associated with recanalization of intraluminal thrombi in acute stroke patients on heparin. Recanalization of intraluminal thrombi are not associated with average PTT or duration on heparin.
