Symptomatic Intracranial Hemorrhage With Tenecteplase vs Alteplase in Patients With Acute Ischemic Stroke: The Comparative Effectiveness of Routine Tenecteplase vs Alteplase in Acute Ischemic Stroke (CERTAIN) Collaboration.

Importance: Symptomatic intracranial hemorrhage (sICH) is a serious complication of stroke thrombolytic therapy. Many stroke centers have adopted 0.25-mg/kg tenecteplase instead of alteplase for stroke thrombolysis based on evidence from randomized comparisons to alteplase as well as for its practical advantages. There have been no significant differences in symptomatic intracranial hemorrhage (sICH) reported from randomized clinical trials or published case series for the 0.25-mg/Kg dose. Objective: To assess the risk of sICH following ischemic stroke in patients treated with tenecteplase compared to those treated with alteplase. Design, Setting, and Participants: This was a retrospective observational study using data from the large multicenter international Comparative Effectiveness of Routine Tenecteplase vs Alteplase in Acute Ischemic Stroke (CERTAIN) collaboration comprising deidentified data on patients with ischemic stroke treated with intravenous thrombolysis. Data from more than 100 hospitals in New Zealand, Australia, and the US that used alteplase or tenecteplase for patients treated between July 1, 2018, and June 30, 2021, were included for analysis. Participating centers included a mix of nonthrombectomy- and thrombectomy-capacity comprehensive stroke centers. Standardized data were abstracted and harmonized from local or regional clinical registries. Consecutive patients with acute ischemic stroke who were considered eligible and received thrombolysis at the participating stroke registries during the study period were included. All 9238 patients who received thrombolysis were included in this retrospective analysis. Main Outcomes and Measures: sICH was defined as clinical worsening of at least 4 points on the National Institutes of Health Stroke Scale (NIHSS), attributed to parenchymal hematoma, subarachnoid, or intraventricular hemorrhage. Differences between tenecteplase and alteplase in the risk of sICH were assessed using logistic regression, adjusted for age, sex, NIHSS score, and thrombectomy. Results: Of the 9238 patients included in the analysis, the median (IQR) age was 71 (59-80) years, and 4449 patients (48%) were female. Tenecteplase was administered to 1925 patients. The tenecteplase group was older (median [IQR], 73 [61-81] years vs 70 [58-80] years; P < .001), more likely to be male (1034 of 7313 [54%] vs 3755 of 1925 [51%]; P < .01), had higher NIHSS scores (median [IQR], 9 [5-17] vs 7 [4-14]; P < .001), and more frequently underwent endovascular thrombectomy (38% vs 20%; P < .001). The proportion of patients with sICH was 1.8% for tenecteplase and 3.6% for alteplase (P < .001), with an adjusted odds ratio (aOR) of 0.42 (95% CI, 0.30-0.58; P < .01). Similar results were observed in both thrombectomy and nonthrombectomy subgroups. Conclusions and Relevance: In this large study, ischemic stroke treatment with 0.25-mg/kg tenecteplase was associated with lower odds of sICH than treatment with alteplase. The results provide evidence supporting the safety of tenecteplase for stroke thrombolysis in real-world clinical practice.

A practice game changer: Impact of tenecteplase for acute ischemic stroke in a multicenter quality improvement project.

PURPOSE: Tenecteplase is a thrombolytic that is more fibrin specific, has a longer half-life, and is easier to administer than alteplase for acute ischemic stroke (AIS). This article outlines the pharmacy experience and perspective on implementation of tenecteplase as the treatment of choice for AIS. SUMMARY: Tenecteplase has been of increasing interest for AIS and is currently being studied in several clinical trials. Although it is not indicated by the Food and Drug Administration for AIS, several published studies and an update to stroke guidelines from the American Heart Association and American Stroke Association support its use in this setting. In January 2021, Cedars-Sinai Health System made the decision to add tenecteplase to the formulary for AIS in addition to keeping alteplase for patients who met the criterion of being outside the 4.5-hour window following stroke onset. Along with the added benefits of having tenecteplase on formulary come challenges of managing multiple thrombolytics for the same indication. Identifying key stakeholders and creating an interdisciplinary team are critical to ensure safe transitions. CONCLUSION: Institutions can safely transition from alteplase to tenecteplase as a thrombolytic of choice for AIS.

COVID-19 Impact on Acute Ischemic Stroke Treatment at 9 Comprehensive Stroke Centers across Los Angeles.

OBJECTIVE: To describe the impact of COVID-19 on acute cerebrovascular disease care across 9 comprehensive stroke centers throughout Los Angeles County (LAC). METHODS: Volume of emergency stroke code activations, patient characteristics, stroke severity, reperfusion rates, treatment times, and outcomes from February 1 to April 30, 2020, were compared against the same time period in 2019. Demographic data were provided by each participating institution. RESULTS: There was a 17.3% decrease in stroke code activations across LAC in 2020 compared to 2019 (1,786 vs. 2,159, respectively, χ2 goodness of fit test p < 0.0001) across 9 participating comprehensive stroke centers. Patients who did not receive any reperfusion therapy decreased by 16.6% in 2020 (1,527) compared to 2019 (1,832). Patients who received only intravenous thrombolytic (IVT) therapy decreased by 31.8% (107 vs. 157). Patients who received only mechanical thrombectomy (MT) increased by 3% (102 vs. 99). Patients who received both IVT and MT decreased by 31.8% (45 vs. 66). Recanalization treatment times in 2020 were comparable to 2019. CSCs serving a higher proportion of Latinx populations in the eastern parts of LAC experienced a higher incidence of MT in 2020 compared to 2019. Mild increase in stroke severity was seen in 2020 compared to 2019 (8.95 vs. 8.23, p = 0.046). A higher percentage of patients were discharged home in 2020 compared to 2019 (59.5 vs. 56.1%, p = 0.034), a lower percentage of patients were discharged to skilled nursing facility (16.1 vs. 20.7%, p = 0.0004), and a higher percentage of patients expired (8.6 vs. 6.3%, p = 0.008). CONCLUSION: LAC saw a decrease in overall stroke code activations in 2020 compared to 2019. Reperfusion treatment times remained comparable to prepandemic metrics. There has been an increase in severe stroke incidence and higher volume of thrombectomy treatments in Latinx communities within LAC during the pandemic of 2020. More patients were discharged home, less patients discharged to skilled nursing facilities, and more patients expired in 2020, compared to the same time frame in 2019.

COVID-19 Is a Catalyst for Future Changes in Stroke Nursing Care.

INTRODUCTION: During the COVID-19 pandemic, hospitals still have to meet external regulations while delivering compassionate patient care. This reflections article provides a solution for certified stroke programs to continue to meet stroke certification requirements. One area of focus, in this article, is stroke education. Because of "shelter-in-place orders," there were no visitors permitted at the bedside, yet we know that high-quality poststroke education is important to improve outcomes. The purpose of this reflections article is to share what has worked at my institution. INNOVATIONS: We found that calling family members to engage them in stroke education was a great option. They seemed engaged, took notes, and asked questions. Nurses document details from these phone encounters in the patient's medical record. Many people placed the call on speaker so other family members could listen to the education session. While family members were at home, telehealth nursing has its own set of challenges. Although telehealth is not a perfect solution, it was one we found most reasonable and found it to work well through this unprecedented time. SUMMARY: These strategies are being shared to promote dissemination of innovative nursing interventions that will help to continue providing loved ones with the information and education they deserve to receive even during the COVID-19 pandemic.

The Simplest Idea Is the Best Idea.

A collaborative approach was used to ascertain an appropriate stimulus for the patients to remember their stroke-specific education. The stroke education had to stand out amidst the myriad of papers and folders patients are bombarded with in the hospital. The team came up with the simple idea of using a bright red folder. When the patients were called, the call center would prompt the patient by saying, "The stroke education was given to you in a bright red folder." Before the implementation of the red folders, only 81.5% of the patients remembered receiving stroke education. After the implementation of the red folders, 96.8% remembered receiving stroke education. The principle of Occam's razor proved to be correct in our study. A very simple idea such as changing the color of the folders to bright red proved to have very meaningful results.

Stroke vs. status epilepticus. A case report utilizing CT perfusion.

Strokes and seizures have varied presentations and their differentiation may be challenging for both primary care physicians and neurologists. We present a case of a patient evaluated for acute ischemic stroke. Status epilepticus was eventually diagnosed by utilizing CT-perfusion study and EEG.
