Canadian Stroke Best Practice Recommendations: Hyperacute Stroke Care Guidelines, Update 2015

Abstract

The 2015 update of the Canadian Stroke Best Practice Recommendations Hyperacute Stroke Care guideline highlights key elements involved in the initial assessment, stabilization, and treatment of patients with transient ischemic attack (TIA), ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage, and acute venous sinus thrombosis. The most notable change in this 5th edition is the addition of new recommendations for the use of endovascular therapy for patients with acute ischemic stroke and proximal intracranial arterial occlusion. This includes an overview of the infrastructure and resources required for stroke centers that will provide endovascular therapy as well as regional structures needed to ensure that all patients with acute ischemic stroke that are eligible for endovascular therapy will be able to access this newly approved therapy; recommendations for hyperacute brain and enhanced vascular imaging using computed tomography angiography and computed tomography perfusion; patient selection criteria based on the five trials of endovascular therapy published in early 2015, and performance metric targets for important time-points involved in endovascular therapy, including computed tomography-to-groin puncture and computed tomography-to-reperfusion times. Other updates in this guideline include recommendations for improved time efficiencies for all aspects of hyperacute stroke care with a movement toward a new median target door-toneedle time of 30 min, with the 90th percentile being 60 min. A stronger emphasis is placed on increasing public awareness of stroke with the recent launch of the Heart and Stroke Foundation of Canada FAST signs of stroke campaign; reinforcing the public need to seek immediate medical attention by calling 911; further engagement of paramedics in the prehospital phase with prehospital notification to the receiving emergency department, as well as the stroke team, including neuroradiology; updates to the triage and same-day assessment Conflict of interest: Leanne K. Casaubon: Medtronic (as an independent study patient assessor for a cardiac TAVI study); NoNO Inc. as site PI for the Frontier study of NA-1 neuroprotective in stroke; Covidien as an advisory board member. Jean-Martin Boulanger: conference speaker for BI Novartis, Sanofi Aventis, Merck, Merz, Allergan, Pfizer, Bayer, Boehringer Ingelheim. Gord Gubitz: speaker for Bayer, Boehringer Ingleheim, and BMS Pfizer. Dr. Michael D. Hill: Heart and Stroke Foundation of Alberta Board Chair, salary award holder; Vernalis Group Ltd and Merck Ltd Consultant; Hoffmann-LaRoche Canada, provided drug for clinical trial, consultancy and CME lecturer; Coviden, research grant holder; Servier Canada, CME lecturer (funds donated to charity); BMS Canada, consultancy (funds donated to charity); Alberta Innovates Health Solutions, program grant award; principal investigator, ESCAPE trial. Brian Moses: speaker for AstraZeneca, Bayer, Boehringer Ingelheim, Sanofi Aventis, and Servier; speaker and advisory board member for BMS, Eli Lilly, Merck, NovoNordisk, Pfizer; advisory board member for Medtronic. Funding: The development of the Canadian Stroke Best Practice Recommendations is funded in their entirety by the Heart and Stroke Foundation, Canada. No funds for the development of these guidelines come from commercial interests, including pharmaceutical and medical device companies. All members of the recommendation writing groups and external reviewers are volunteers and do not receive any remuneration for participation in guideline development, updates, and reviews. All participants complete a conflict of interest declaration prior to participation. of patients with transient ischemic attack; updates to blood pressure recommendations for the hyperacute phase of care for ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage. The goal of these recommendations and supporting materials is to improve efficiencies and minimize the absolute time lapse between stroke symptom onset and reperfusion therapy, which in turn leads to better outcomes and potentially shorter recovery times
