The CSBPR Acute Stroke Management module provides guidance to healthcare providers caring for people who present to the healthcare system with current or very recent symptoms of acute stroke or transient ischemic attack (TIA). This module also addresses the issue of public and healthcare providers’ recognition of the signs of stroke and immediate actions that should be taken, including contacting emergency medical services (EMS), arriving at a stroke-enabled emergency department, and launching local healthcare institution code stroke protocols.
This module is presented in two parts. Part 1 addresses prehospital and emergency management of acute stroke, while Part 2 addresses acute inpatient stroke care (Figure 1).
- Sections 1 to 7 in the Acute Stroke Management module address prehospital and emergency department stroke care. This encompasses all direct care, investigations, interventions, service delivery, and interactions from first contact with the healthcare system after the onset of an acute stroke or TIA (usually by contacting EMS or presenting at a healthcare facility) through to discharge from an emergency department to another healthcare facility (usually with a higher or lower level of stroke care), an acute inpatient care unit, or the community. Sections 1 to 4 apply to all potential patients with stroke arriving at hospital; sections 5 and 6 are specific to people experiencing an acute ischemic stroke; and section 7 applies to all confirmed stroke and TIA patients.
- Sections 8 to 11 address acute inpatient stroke care. This encompasses all direct care, investigations, interventions, service delivery, and interactions from the time a person with stroke is admitted to an acute care hospital.
With each update of the Canadian Stroke Best Practice modules, the most current evidence on the included topics is reviewed by the writing group members and internal and external reviewers. Recommendations from the previous edition may be continued unchanged, modified to reflect updated evidence (either wording or evidence levels), or removed. New recommendations may be added to address emerging evidence and practice changes.
The following are the most notable areas that have been added or significantly revised in this 7th edition of the CSBPR Acute Stroke Management module.
- Sex and gender considerations: Specific attention has been given to potential differences in care and outcomes of acute stroke based on sex and gender. We are mindful that sex (a collection of biological attributes) and gender (a psycho-social construct related to our identity), may affect stroke care and outcomes differently; however, it is recognized that gender is not binary and that the literature, until recent years, used the terms gender and sex interchangeably in publications, and there are few current studies that differentiate between sex and gender. The terms “men” and “women” are used throughout the guideline to refer to people of male and female sex, with an appreciation that the gender constructs may have additional impacts and that this is an area requiring further research and reporting requirements.
- Evidence rating scale: Changed from the previous scale of A, B, C to the scale applied within the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methodology.
- Imaging: All recommendations related to imaging in the early phase of acute stroke have been consolidated into Section 4.
- Addition of tenecteplase: Based on new clinical trial evidence released in 2022, new recommendations for the use of tenecteplase (TNK) as an alternative to alteplase for acute intravenous thrombolysis has been added to Section 5.
- Symptomatic intracranial hemorrhage (sICH): New recommendations have been included in Section 5 on management of sICH following administration of intravenous thrombolysis.
- Pre- and post- endovascular thrombectomy care: New clinical practice guidance has been included in Section 5, Box 5D on the care of people undergoing EVT, pre and post procedure.
- Combined intravenous thrombolysis and EVT: A new clinical consideration has been added to Section 5 to address recent trials regarding combined therapy versus EVT alone, reflecting the current uncertainty in the evidence.
- Dual antiplatelet therapy: New recommendations have been added to Section 6 regarding the use of dual antiplatelet therapy (DAPT) in people who have experienced an acute ischemic stroke. These new recommendations are aligned with recommendations in the CSBPR Secondary Prevention of Stroke module, 2020.
- Medical Assistance in Dying (MAiD): New statements have been added to Section 11 regarding discussions about MAiD with appropriate patients and family members.
- Virtual care: New and updated recommendations for virtual stroke care in the emergency department and inpatient care have been added to Sections 4, 5, and 9 to reflect the sustainable integration of this modality into daily care for people with stroke.
- Mobile stroke units: A clinical consideration has been added to Section 3 on the use of mobile stroke units.
The detailed methodology and explanations for each of these steps in the development and dissemination of the CSBPR is available in the Canadian Stroke Best Practice Recommendations Overview and Methodology manual.
Conflicts of interest
All potential participants in the recommendation development and review process are required to complete confidentiality agreements and declare all actual and potential conflicts of interest prior to participation. Declared conflicts of interest are reviewed by the co-chairs of the CSBPR Advisory Committee and Heart & Stroke staff to assess the potential impact. Those with significant conflicts with respect to the module topic are not selected for writing group or reviewer roles. Participants who have conflicts for a particular topic area are identified at the beginning of discussions for that topic and are recused from voting. If a co-chair is in conflict, they are recused from their responsibilities for that discussion and another non-conflicted participant assumes the role for that discussion and vote. Heart & Stroke senior staff members participate in all writing group discussions and intervene if they perceive an untoward bias by a writing group member. Conflict of interest declarations for the Acute Stroke Management module writing group members can be found in Appendix 1.
