Abstract Background Rates of thrombolysis in most countries are well below best practice benchmarks. We aimed to investigate thrombolysis utilization and its associated factors in acute ischemic stroke (AIS) patients in Hubei province, China, to assess neurologists’ experiences of the treatment, and to identify barriers against the treatment from perspective of AIS patients and neurologists. Methods Survey of 2096 AIS patients and 709 neurologists from 66 hospitals was conducted in Hubei province between 2014 and 2015. A multivariable logistic regression model was utilized to identify the factors associated with thrombolysis utilization and neurologists’ experiences with thrombolysis. Results Of the 2096 AIS patients, only 3.8% received thrombolysis. Of the 709 neurologists, 66.0% reported using thrombolysis for AIS patients. The main reasons for not using thrombolysis were late arrival of patients, fear of the risk of complications of thrombolysis, and light or quickly recovered stroke symptoms. The behavior and clinical characteristics of patients, including early admission to hospital (odds ratio [OR]=5.81, 95% confidence intervals [CI] 3.31-10.20), using emergency medical services to be hospitalized (OR=3.36, 95% CI 2.00-5.62), stroke history (OR=0.53, 95% CI 0.28-0.99), and National Institute of Health Stroke Scale score < 4 (OR=0.46, 95% CI 0.27-0.77) were shown to significantly affect the thrombolysis utilization in the multivariate model. In addition, hospital grade (OR=2.84, 95% CI 1.84-4.37), education level (OR=2.49, 95% CI 1.09-5.73), and working years (OR=1.88, 95% CI 1.18-3.00) were strongly associated with neurologists’ experiences of thrombolysis. Conclusions A very low proportion of AIS patients received thrombolysis in Hubei province, China. Considerable education programs and interventions were required regarding knowledge of stroke treatment for clinicians and proper behavior after stroke for AIS patients and their families.

Background Stroke rehabilitation improves functional recovery among stroke patients. However, little is known about clinical practice in China regarding the assessment and provision of rehabilitation among patients with acute ischemic stroke. Aims We examined the frequency and determinants of an assessment for rehabilitation among acute ischemic stroke patients from the China National Stroke Registry II. Methods Data for 19,294 acute ischemic stroke patients admitted to 219 hospitals from June 2012 to January 2013 were analyzed. The multivariable logistic regression model with the generalized estimating equation method accounting for in-hospital clustering was used to identify patient and hospital factors associated with having a rehabilitation assessment during the acute hospitalization. Results Among 19,294 acute ischemic stroke patients, 11,451 (59.4%) were assessed for rehabilitation. Rates of rehabilitation assessment varied among 219 hospitals (IQR 41.4% vs 81.5%). In the multivariable analysis, factors associated with increased likelihood of a rehabilitation assessment ( p < 0.05) included disability prior to stroke, higher NIHSS on admission, receipt of a dysphagia screen, deep venous thrombosis prophylaxis, carotid vessel imaging, longer length of stay, and treatment at a hospital with a higher number of hospital beds (per 100 units). In contrast, patients with a history of atrial fibrillation and hospitals with higher number of annual stroke discharges (per 100 patients) were less likely to receive rehabilitation assessment during the acute stroke hospitalization. Conclusions Rehabilitation assessment among acute ischemic stroke patients was suboptimal in China. Rates varied considerably among hospitals and support the need to improve adherence to recommended care for stroke survivors.

Social Security Death Index

Introduction: Despite randomized trials demonstrating the benefit of endovascular therapy (EVT), large artery occlusion (LAO) acute ischemic stroke (AIS) remains associated with high mortality. Identifying factors associated with mortality for patients presenting with LAO AIS can assist in therapeutic decision-making and prognostication. Hypothesis: Among patients with LAO AIS, factors associated with 90-day mortality include older age, higher presenting NIHSS score, and lower final Thrombolysis in Cerebral Infarction (TICI) score. Methods: From November 2016 to April 2019, we conducted a retrospective analysis from a large healthcare system’s stroke network registry of patients presenting with ICA and/or MCA occlusions. Ninety-day mortality status from registry follow-up was corroborated with the Social Security Death Index. A multivariable logistic regression model was fitted to determine demographic and clinical characteristics associated with 90-day mortality. Results: Among 796 patients with 800 encounters, mean age was 68 years, 52% were women, mean presenting NIHSS was 14, and 97% presented within 24 hours of last known well time. Fifty-one percent were treated with EVT. Mortality rate for the entire cohort was 25%. In a univariate analysis, there were significant differences in age, gender, race, blood glucose, presenting NIHSS, hypertension, atrial fibrillation, CTP core volume, CTP delayed perfusion volume, EVT treatment, number of passes for EVT, final TICI score, and discharge mRS, between patients with and without 90-day mortality. In the multivariable model, increasing age (per 10 years, OR 1.54, 95% CI 1.20, 1.97) and higher discharge mRS (per 1 point, OR 4.47, 95% CI 3.05, 6.55) were associated with 90-day mortality. Female gender (OR 0.57, 95% CI 0.27, 1.18) and final TICI score of 2B or better (OR 0.42, 95% CI 0.18, 1.01) were protective against 90-day mortality. Conclusions: Increasing age and worse discharge functional outcome are associated with 90-day mortality after LAO AIS. Female gender and better revascularization after EVT are associated with lower mortality. Additional studies are required to refine mortality outcome prediction models for patients presenting with LAO AIS.

Background: Stroke rehabilitation improves functional recovery among stroke patients. However, little is known about clinical practice in China regarding the assessment and provision of rehabilitation among patients with acute ischemic stroke (AIS). Aims: We examined the frequency and determinants of an assessment for rehabilitation among AIS patients from the China National Stroke Registry II. Methods: Data for 19,294 AIS patients admitted to 219 hospitals from June 2012 to January 2013 were analyzed. The multivariable logistic regression model with the generalized estimating equation method accounting for in-hospital clustering was used to identify patient and hospitals factors associated with having a rehabilitation assessment during the acute hospitalization. Results: Among 19,294 AIS patients, 11,451 (59.4%) were assessed for rehabilitation. Rehabilitation assessment rates varied considerably among centers: median 64.8% (interquartile range: 41.4%-83.3%). Factors associated with increased likelihood of a rehabilitation assessment in the multivariable model (p<0.05) included disability prior to this stroke, increasing NIHSS on admission, receiving dysphagia screening, deep venous thrombosis prophylaxis, and carotid vessel imaging, longer length of stay, and increasing hospital beds (per 100 units). In contrast, patients with a history of atrial fibrillation, and increasing annual stroke discharges (per 100 patients) were less likely to receive rehabilitation assessment during the acute stroke hospitalization. Conclusions: Up to a third of patients in China do not receive rehabilitation assessment follow an AIS. Thus, there appears to be opportunities to improve adherence to recommended care for stroke survivors in China.

Treatment of patients with cerebral large vessel occlusion with thrombectomy and tissue plasminogen activator (tPA) leads to incomplete reperfusion. Using rat models of embolic and transient middle cerebral artery occlusion (eMCAO and tMCAO), we investigated the effect on stroke outcomes of small extracellular vesicles (sEVs) derived from rat cerebral endothelial cells (CEC-sEVs) in combination with tPA (CEC-sEVs/tPA) as a treatment of eMCAO and tMCAO in rat. The effect of sEVs derived from clots acquired from patients who had undergone mechanical thrombectomy on healthy human CEC permeability was also evaluated. CEC-sEVs/tPA administered 4 h after eMCAO reduced infarct volume by ∼36%, increased recanalization of the occluded MCA, enhanced cerebral blood flow (CBF), and reduced blood-brain barrier (BBB) leakage. Treatment with CEC-sEVs given upon reperfusion after 2 h tMCAO significantly reduced infarct volume by ∼43%, and neurological outcomes were improved in both CEC-sEVs treated models. CEC-sEVs/tPA reduced a network of microRNAs (miRs) and proteins that mediate thrombosis, coagulation, and inflammation. Patient-clot derived sEVs increased CEC permeability, which was reduced by CEC-sEVs. CEC-sEV mediated suppression of a network of pro-thrombotic, -coagulant, and -inflammatory miRs and proteins likely contribute to therapeutic effects. Thus, CEC-sEVs have a therapeutic effect on acute ischemic stroke by reducing neurovascular damage.

Background: The benefits of intravenous tPA in acute ischemic stroke are time-dependent with guidelines recommending a door-to-needle (DTN) time of ≤60 minutes. The implementation of Target: Stroke Phase I in 2010 was associated with an increase in the proportion of patients with DTN times ≤60 minutes in the US from 28.9% in 2009 to 51.0% in 2013. This study aims to assess whether these improvements in DTN times could be maintained or further improved since the launch of Target: Stroke Phase II in Q2 2014. Methods: Target: Stroke Phase II identified and disseminated additional best practice strategies, provided updated clinical decision support tools, and set new hospital recognition goals. Rates of DTN times ≤60 minutes were compared during final 4 quarters of Phase I (Q4 2012-Q3 2013) vs. Phase II (Q2 2014-Q1 2015) and overall by linear weighted regression. Results: There were 99,176 intravenous tPA treated patients from 1228 GWTG-Stroke hospitals. Patient characteristics were similar during Phase I and II. Median DTN time significantly declined from the last 4 quarters of Phase I to the first 4 quarters of Phase II: 61 minutes (IQR 47-81) to 57 minutes (IQR 43-74) (P<0.0001). The % of patients with DTN times ≤60 minutes increased from last 4 quarters of Phase I to Phase II: 49.7% to 58.5%, absolute difference +8.8%, (P<0.0001). The % of patients with DTN times ≤45 minutes also increased from Phase I to Phase II: 22.0% to 29.2%, absolute difference +7.2%, (P<0.0001). The estimated annual rate of increase in patients with DTN times ≤60 minutes was 0.6% per year pre-Target Stroke, 5.6% per year during Phase I, and 8.6% in the first year of Phase II (P<0.0001) (Figure). Conclusions: The timeliness of tPA administration is continuing to improve in GWTG-Stroke hospitals participating in Target: Stroke Phase II. Nevertheless, ongoing quality improvement efforts will be required to meet the goals of ≥75% of patients with DTN times ≤60 minutes and ≥50% of patients with DTN times ≤ 45 minutes.

Introduction : Previous research into the administration of rTPA therapy in acute ischemic stroke patients has largely focused on the general population, however the comorbid clinical factors held by stroke patients are important factors in clinical decision making. One such comorbid condition is Atrial Fibrillation. The purpose of this study is to determine the clinical factors associated with the administration of rtPA in Acute Ischemic Stroke (AIS) patients specifically with a past medical history of Atrial Fibrillation (AFib). Methods : The data for this analysis was collected at a regional stroke center from January 2010 to June 2016 in Greenville, SC. It was then analyzed retrospectively using a multivariate logistic regression to identify factors significantly associated with the inclusion or exclusion receiving rtPA therapy in the AIS/AFib patient population. This inclusion or exclusion is presented as an Odds Ratio and all data was analyzed using IBM SPSS. Results : A total of 158 patients with Atrial Fibrillation who had Acute Ischemic Strokes were identified. For the 158 patients, the clinical factors associated with receiving rtPA therapy were a Previous TIA event (OR = 12.155, 95% CI, 1.125‐131.294, P < 0.040), the administration of Antihypertensive medication before admission (OR = 7.157, 95% CI, 1.071‐47.837, P < 0.042), the administration of Diabetic medication before admission (OR = 13.058, 95% CI, 2.004‐85.105, P < 0.007), and serum LDL level (OR = 1.023, 95% CI, 1.004‐1.042, P < 0.16). Factors associated with not receiving rtPA therapy included a past medical history of Depression (OR = 0.012, 95% CI, 0.000‐0.401, P < 0.013) or Obesity (OR = 0.131, 95% CI, 0.034‐0.507, P < 0.003), Direct Admission to the Neurology Floor (OR = 0.179, 95% CI, 0.050‐0.639, P < 0.008), serum Lipid level (OR = 0.544, 95% CI, 0.381‐0.984, P < 0.044), and Diastolic Blood Pressure (OR = 0.896, 95% CI, 0.848‐0.946, P < 0.001). Conclusions : The results of this study demonstrate that there are significant associations between several clinical risk factors, patient lab values, and hospital admission factors in the administration of rTPA therapy to AIS patients with a past medical history of Atrial Fibrillation. Further research is recommended to determine the extent and reasoning behind of these associations as well as their impact on the clinical course for AIS/AFib patients.

Background: Recent trials have demonstrated a reduction in death or disability with endovascular treatment in patients with acute ischemic strokes. However, readmission rates and predictors are not known. Objective: To identify rates and factors associated with 30-day readmission after endovascular treatment in ischemic stroke patients. Methods: Nationwide Readmissions Data (NRD) between 2010 and 2017 was utilized to identify endovascular treatment in acute ischemic stroke patients using ICD-9 and ICD-10 codes. We used hierarchical logistic regression model to identify factors associated with 30-day readmissions. Results: Among 17, 562 acute ischemic stroke patients who survived to discharge after endovascular treatment, 2334 (13.29%) were readmitted within 30-days. Age => 65 years (odds ratio [OR]: 1.23, 95% confidence interval [CI]: 1.09 to 1.39, p =0.0005), chronic kidney disease (OR: 1.28, 95%CI: 1.12 to 1.47, p = 0.0004), congestive heart failure (OR: 1.25, 95%CI: 1.13 to 1.39, p <.0001), post procedure intracranial hemorrhage (OR: 1.09, 95%CI: 0.99 to 1.20, p = 0.04) and diabetes mellitus (OR: 1.09, 95%CI: 0.99 to 1.20, p = .09) during the index hospitalization were associated with readmission within 30 days. Conclusion: In this large nationally representative study, nearly one in 10 patients were readmitted within 30 days after discharge in acute ischemic stroke patients undergoing endovascular treatment. Medical comorbidities and post procedure intracranial hemorrhage were associated with 30-day readmission.

Prevalence and risk factors associated with memory disturbance and dementia were determined in acute ischemic stroke (AIS) patients in hospitals before discharge, three and six months after stroke. A prospective cohort study was conducted during January-December 2017 with 401 AIS patients admitted to Srinagarind Hospital, Khon Kaen Hospital and Chum Phae Hospital, Khon Kaen, Thailand. The demographics and clinical characteristics, previous illness and past medical history, and laboratory test results of the patients were collected from the medical records, while depression screening, NIH stroke scale (NIHSS) scoring and mini mental state examination (MMSE) were performed using particular medical record forms. The prevalence of memory disturbance and dementia was 56.6, 41.6 and 38.2% before discharge, three and six months after stroke, respectively. Based on logistic regression analysis, age, education and stroke severity were the risk factors associated with the studied disorders before discharge and three months after stroke. Meanwhile, age and education were the risk factors for six months after stroke. Our findings suggested that the prevalence of memory disturbance and dementia remained high at all study periods.
