The Impact

Background: Stroke coordinator roles often involve quality data collection and compliance with standards to maintain certification, yet have limited clinical patient contact. Implementing a Clinical Stroke Coordinator Role, with a focus on the patient, assists with care continuity and improves the success rate of follow-up phone calls to acute ischemic stroke patients. Purpose: To evaluate the impact of implementing a Clinical Stroke Coordinator on the percentage of successful patient follow-up phone calls to all acute ischemic stroke patients discharged from the hospital. Methods: Our hospital, a high volume academic medical center, implemented the role of Clinical Stroke Coordinator in October 2014. The Coordinator met with each acute ischemic stroke patient prior to discharge to personalize patient education and stroke risk assessments, and to establish an appropriate contact person and phone number for discharge follow-up phone calls. All patients (or their designee) were called by the nurse Clinical Stroke Coordinator within seven days of hospital discharge to home, rehabilitation or inpatient nursing facility. The percentage of patients reached from February 2015 through July 2015 was compared to data from the preceding year, when calls were made by Unit Managers. Results: Compared with the pre-implementation period, when the average success rate was 49% for 209 patients, implementation of the Clinical Stroke Coordinator led to an average success rate of 86% for 240 patients, most recently reaching 100% of patients discharged. Overall there was a 102% increase in successful patient discharge phone calls for this patient population (Figure). Conclusion: The Clinical Stroke Coordinator role is essential to improved discharge phone call success rates, reaching >95% of acute stroke patients in the most recent three months. Further research is warranted into the impact of follow up phone calls on patient medication compliance and life-style modification.

Background and Objective: Follow-up in outpatient stroke clinic after hospitalization for ischemic stroke is an integral aspect of the management of stroke patients. This study sought to investigate predictors of risk of not following up in outpatient stroke clinic. Methods: We reviewed consecutive acute ischemic stroke patients admitted to an urban academic medical center from 4/2013 to 4/2014. On discharge, all stroke patients except those going to long term acute care received notice of scheduled follow-up stroke clinic appointment date; they also received a phone call 2-3 days prior to the appointment. Univariate analysis examined the relationship between race, ethnicity, marital status, insurance type, and living arrangement with stroke clinic follow up status. Multivariate analysis was performed with logistic regression controlling for significant factors found in our previous study including discharge location, previously documented diagnosis of depression and outpatient physicians at same institution. Results: Among 355 acute ischemic stroke patients, 49% were female and mean age was 65 years. The follow-up rate in stroke clinic was 53%. In univariate analysis, race, ethnicity, marital status, employment status, and insurance type (i.e. self-pay) were not significantly associated with compliance with stroke clinic follow-up. In logistical regression, patients who lived alone were significantly less likely to follow up in stroke clinic compared with those living with family (OR=2.18, 95% CIs=[1.18, 4.03], p=0.01) as were patients who were depressed, (OR=5.99, CIs =[1.47, 24.4], p=0.01) who did not have other doctors at the same institution, (OR=2.23 CIs = [1.31, 3.70] p=0.003] and who were discharged to a facility other than home or acute rehab (OR=4.38, CIs [1.74, 11.03], p=0.003). Conclusions: Institutions taking care of patients with ischemic strokes should be aware that certain patients may be less likely to follow up in clinic and merit additional efforts in order to ensure that they are not lost to follow up.

Long Term Mortality

Background: Cerebral microbleeds (CMBs) were predictive of mortality in elderly and considered as a putative marker for risk of intracranial hemorrhage. Stroke patients with non valvular atrial fibrillation (NVAF) require anticoagulation, which increases the risk of hemorrhages. We investigated association of CMBs with the long term mortality in acute ischemic stroke patients with NVAF. Methods: During 6 years , consecutive ischemic stroke patients who had NVAF and who had undergone brain MRI with a gradient-recalled echo sequence were enrolled. Long-term mortality and causes of death were identified using data from Korean National Statistical Office. Survival analysis was performed whether the presence, number and location of CMBs were related with all causes, cardiovascular, and cerebrovascular mortality during follow-up. Results: Total 506 patients were enrolled during the study period and were followed up for median 2.5 years. CMBs were found in 30.8% of patients (156/506). Oral anticoagulation with warfarin was prescribed at discharge in 477 (82.7%) patients. During follow up, 177 (35%) patients died and cerebrovascular death was noted in 93 patients (81 ischemic stroke and 12 hemorrhagic stroke). After adjusting age, sex and significant variables in univariate analysis (p<0.1), multiple CMBs (≥5) were the independent predictor for all-cause, cardiovascular and ischemic stroke mortalities. The strictly lobar CMBs were associated with hemorrhagic stroke mortality in multivariate Cox regression analysis (HR 4.776, p=0.032) (Figure 1). Conclusions: Multiple CMBs were the independent predictor for the long term mortality in stroke patients with NVAF. Among them, patients with strictly lobar CMBs had a high risk of death due to hemorrhagic stroke. Our findings suggest that detection of CMBs in stroke patients with NVAF are of clinical relevance for predicting long term outcome and that particular concern is necessary in those with strictly lobar CMBs for their increased risk of death due to hemorrhagic stroke.

Background/Objective: There is growing importance on discovering factors that delay time to intervention for acute ischemic stroke (AIS) patients, as rapid intervention remains essential for better patient outcomes. The management of these patients involves a multidisciplinary effort and quality improvement initiatives to safely increase treatment with intravenous thrombolytic (IV tPa). The objective of this pilot is to evaluate factors of acute stroke care in the emergency department (ED) and the impact they have on IV tPa administration. Methods: A sample of 89 acute ischemic stroke patients that received IV tPa from a single academic medical institution was selected for retrospective analysis. System characteristics (presence of a stroke nurse and time of day) and patient characteristics (mode of arrival and National Institutes of Health Stroke Scale score (NIHSS) on arrival) were analyzed using descriptive statistics and multiple regression to address the study question. Results: The mean door to needle time is 53.74 minutes ( + 38.06) with 74.2% of patients arriving to the ED via emergency medical services (EMS) and 25.8% having a stroke nurse present during IV tPa administration. Mode of arrival ( p = .001) and having a stroke nurse present ( p = .022) are significant predictors of door to needle time in the emergency department (ED). Conclusion: While many factors can influence door to needle times in the ED, we did not find NIHSS on arrival or time of day to be significant factors. Patients arriving to the ED by personal vehicle will have a significant delay in IV tPa administration, therefore emphasizing the importance of using EMS. Perhaps more importantly, collaborative efforts including the addition of a specialized stroke nurse significantly decreased time to IV tPa administration for AIS patients. With this dedicated role, accelerated triage and more effective management of AIS patients is accomplished, leading to decreased intervention times and potentially improving patient outcomes.

Introduction : In acute ischemic stroke patients, current guidelines recommend noninvasive vascular imaging to identify intracranial vessel occlusions (VO) that may benefit from endovascular treatment (EVT). However, VO can be missed in CT angiography (CTA) readings. We aim to evaluate the impact of consistently including CT perfusion (CTP) in admission stroke imaging protocols on VO diagnosis and EVT rates. Methods : We included patients with a suspected acute ischemic stroke that underwent urgent non‐contrast CT, CTA and CTP from April to October 2020. Hypoperfusion areas defined by Tmax>6s delay (RAPID software), congruent with the clinical symptoms and a vascular territory, were considered due to a VO (CTP‐VO). Cases in which mechanical thrombectomy was performed were defined as therapeutically relevant VO (EVT‐VO). For patients that received EVT, site of VO according to digital subtraction angiography was recorded. Two experienced neuroradiologists blinded to CTP but not to clinical symptoms, retrospectively evaluated NCCT and CTA to identify intracranial VO (CTA‐VO). We analyzed CTA‐VO sensitivity and specificity at detecting CTP‐VO and EVT‐VO respecitvely. We performed a logistic regression to test the association of Tmax>6s volumes with CTA‐VO identification and indication of EVT. Results : Of the 338 patients included in the analysis, 157 (46.5%) presented a CTP‐VO, (median Tmax>6s: 73 [29‐127] ml). CTA‐VO was identified in 83 (24.5%) of the cases. Overall CTA‐VO sensitivity for the detection of CTP‐VO was 50.3% and specificity was 97.8%. Higher hypoperfusion volume was associated with an increased CTA‐VO detection, with an odds ratio of 1.03 (95% confidence interval 1.02‐1.04) (figure). DSA was indicated in 107 patients; in 4 of them no EVT was attempted due to recanalization or a too distal VO in the first angiographic run. EVT was performed in 103 patients (30.5%. Tmax>6s: 102 [63‐160] ml), representing 65.6% of all CTP‐VO. Overall CTA‐VO sensitivity for the detection of EVT‐VO was 69.9%. The CTA‐VO sensitivity for detecting patients with indication of EVT according to clinical guidelines was as follows: 91.7% for ICA occlusions and 84.4% for M1‐MCA occlusions. For all other occlusion sites that received EVT, the CTA‐VO sensitivity was 36.1%. The overall specificity was 95.3%. Among patients who received EVT, CTA‐VO was not detected in 31 cases, resulting in a false negative rate of 30.1%. False negative CTA‐VO cases had lower Tmax>6s volumes (69[46‐99.5] vs 126[84‐169.5]ml, p<0.001) and lower NIHSS (13[8.5‐16] vs 17[14‐21], p<0.001). Conclusions : Systematically including CTP perfusion in the acute stroke admission imaging protocols may increase the diagnosis of VO and rate of EVT.

Introduction: The effects of blood pressure (BP) reduction on clinical outcomes among acute stroke patient remain uncertain. Hypothesis: We tested the effects of immediate BP reduction on death and major disability at 14 days or hospital discharge and 3-month follow-up in acute ischemic stroke patients with and without a previous history of hypertension or use of antihypertensive medications. Methods: The China Antihypertensive Trial in Acute Ischemic Stroke (CATIS) randomly assigned patients with ischemic stroke within 48 hours of onset and elevated systolic BP (SBP) to receive antihypertensive treatment (N=2,038) or to discontinue all antihypertensive medications (N=2,033) during hospitalization. Randomization was stratified by participating hospitals and use of antihypertensive medications. Study outcomes were assessed at 14 days or hospital discharge and 3-month post-treatment follow-up. The primary outcome was death and major disability (modified Rankin Scale score≥3), and secondary outcomes included recurrent stroke and vascular events. Results: Mean SBP was reduced 12.7% in the treatment group and 7.2% in the control group within 24 hours after randomization (P<0.001). Mean SBP was 137.3 mmHg in the treatment group and 146.5 in the control group at day 7 after randomization (P<0.001). At 14 days or hospital discharge, the primary and secondary outcomes were not significantly different between the treatment and control groups by subgroups. At the 3-month follow-up, recurrent stroke was significantly reduced in the antihypertensive treatment group among patients with a history of hypertension (odds ratio 0.43, 95% CI 0.24-0.75, P=0.003) and among patients with a history of use of antihypertensive medications (odds ratio 0.41, 95% CI 0.20-0.84, P=0.01). All-cause mortality (odds ratio 2.84, 95% CI 1.11-7.27, P=0.03) was increased among patients without a history of hypertension. Conclusion: Immediate BP reduction lowers recurrent stroke among acute ischemic stroke patients with a previous history of hypertension or use of antihypertensive medications at 3 months. On the other hand, BP reduction increases all-cause mortality among patients without a history of hypertension.

Introduction/Background information: At the onset of acute stroke symptoms, speed, capability, safety and skill are essential-lost minutes can be the difference between full recoveries, poor outcome, or even death. The Joint Commission's Certificate of Distinction for Comprehensive Stroke Centers recognizes centers that make exceptional efforts to foster better outcomes for stroke care. While many hospitals have been surveyed, Cedars Sinai was the 5 th hospital in the nation to receive this certification. Researchable question: Does Comprehensive stroke certification (CSC) demonstrate a significant effect on volume and quality of care? Methods: We assembled a cross-functional, multidisciplinary expert team representing all departments and skill sets involved in treating stroke patients. We carefully screened eligible patients with acute ischemic stroke We assessed the number of patients treated at Cedars-Sinai with IV-T-pa t 6 months before and then 6 months after CSC and the quality of their care including medical treatment and door to needle time. Results: In the 6 months prior to Joint Commissions Stroke Certification we treated 20 of 395acute stroke patients with t-PA with an average CT turnaround time of 31±19minutes and an average Door to needle time (DTNT) of 68±32minutes. In the 6 months since Joint Commission Stroke Certification we have increased the number of acute stroke patients treated by almost double. There were 37 out of 489(P=0.02, Chi Square) patients treated with IV t-PA with an average CT turnaround time of 22±7minutes (p=0.08, t-test, compared to pre-CSC) and an average DTNT of 61± 23minutes (not different than pre-CSC). Conclusion: We conclude that Joint Commission Certification for stroke was associated with an increased rate of treatment with IV rt-PA in acute ischemic stroke patients. We were not able to document an effect on quality of care. Further studies of the impact of CSC certification are warranted.

New Devices

Interventional neuroradiology is characterized by engineering- and experience-driven device development with design improvements every few months. However, clinical validation of these new devices requires lengthy and expensive randomized controlled trials. This contribution proposes a machine learning-based in silico study design to evaluate new devices more quickly with a small sample size. Acute diffusion- and perfusion-weighted MRI, segmented one-week follow-up imaging, and clinical variables were available for 90 acute ischemic stroke patients. Three treatment option-specific random forest models were trained to predict the one-week follow-up lesion segmentation for (1) patients successfully recanalized using intra-arterial mechanical thrombectomy, (2) patients successfully recanalized using intravenous thrombolysis, and (3) non-recanalizing patients as an analogue for conservative treatment for each patient in the sample, independent of the true group membership. A repeated-measures analysis of the three predicted follow-up lesions for each patient revealed significantly larger lesions for the non-recanalizing group compared to the successful intravenous thrombolysis treatment group, which in turn showed significantly larger lesions compared to the successful mechanical thrombectomy treatment group (p < 0.001). A groupwise comparison of the true follow-up lesions for the three treatment options showed the same trend but did not reach statistical significance (p = 0.19). We conclude that the proposed machine learning-based in silico trial design leads to clinically feasible results and can support new efficacy studies by providing additional power and potential early intermediate results.

Abstract Background: Recent studies have suggested that omentin-1 plays a critical role in the development of cardiovascular disease. However, reported findings are inconsistent, and no study has evaluated the association between omentin-1 levels and a poor functional outcome after ischemic stroke onset. Methods: A total of 266 acute ischemic stroke patients were included in this study. All patients were prospectively followed up for 3 months after acute ischemic stroke onset and a poor functional outcome was defined as a major disability or death occurring during the follow-up period. A multivariable logistic model was used to evaluate the association between serum omentin-1 levels and the functional outcome of ischemic stroke patients at 3 months. Results: Ischemic stroke patients with poor functional outcome had significantly lower levels of serum omentin-1 than patients without poor functional outcome at the 3-month follow-up (50.2 [40.2–59.8] vs. 58.3 [44.9–69.6] ng/mL, p<0.01). Subjects in the highest tertile of serum omentin-1 levels had a 0.38-fold risk of having poor functional outcome, compared with those in the lowest tertile (p<0.05). A negative association between omentin-1 levels and poor functional outcome was found (p for trend=0.02). The net reclassification index was significantly improved in predicting poor functional outcome when omentin-1 data was added to the multivariable logistic regression model. Conclusions: Higher omentin-1 levels at baseline were negatively associated with poor functional outcome among ischemic stroke patients. Omentin-1 may represent a biomarker for predicting poor functional outcome of acute ischemic stroke patients.

Introduction: The efficacy of endovascular thrombectomy in an extended time window for acute ischemic stroke patients with Target Mismatch (TM) on perfusion imaging was shown in a recent study and the ongoing DEFUSE-3 trial is studying thrombectomy in a 6-16 hour window for TM patients. A limitation of TM is that perfusion imaging is not widely available. We sought to identify a tool to predict TM based on clinical factors and CT angiogram (CTA) imaging, which is available at most hospitals. Methods: We reviewed acute ischemic stroke patients from 2010-2014 with proximal middle cerebral artery occlusion, CTA and CT perfusion (CTP) at hospital admission. TM was identified on CTP using the Olea Sphere volumetric analysis software with Bayesian deconvolution. TM was defined by the DEFUSE-3 criteria. ASPECTS was derived from the non-contrast CT head and the CTA source images (CTA-ASPECTS). Two collateral scores were derived from CTA source images. Results: 61 patients met inclusion criteria. The mean±SD age was 61±18 years and 61% were male. Mean NIH Stroke Scale (NIHSS) was 14.1±8.0 and median (IQR) follow-up modified Rankin Scale was 3 (1,6). TM was present in 35/61 (57%), who had lower mRS at follow-up (z=3.5, p<0.001). The predictor variables are shown in Table 1. The best combination of predictors was CTA-ASPECTS >4 and NIHSS <16, which had a sensitivity of 80% and specificity of 85% for TM (Figure 1). Discussion: We report a reliable, accessible, and clinically useful tool for predicting TM. This score warrants further study as a tool to guide transfer decisions from primary or secondary stroke centers to tertiary centers where endovascular intervention would be possible for selected patients.
