The Acute Stroke System of Treatment Across Canada: Findings from a National Stroke Centre Survey.

Background: Stroke is a devastating disease, but the disability due to stroke can be avoided or reduced through timely access to treatment and care. This study surveyed all designated stroke centres across Canada to better understand the national acute stroke treatment landscape.

Methods: An online survey designed to obtain information on each stroke hospital's designation level, most responsible physician for acute reperfusion treatment decision-making, availability of stroke coordinators, stroke research activity and level of transition to tenecteplase for intravenous thrombolysis was distributed to stroke centres in Canada via a network of stroke administrators and physician leads from each province.

Exploring Innovations and Factors to Optimize Adult Neurosurgery Inpatient Flow in Alberta.

Background: Poorly managed inpatient flow can lead to adverse health outcomes, including increased mortality and readmission rates. In neurosurgery, optimizing inpatient flow is crucial to improving patient experience and outcomes, but the factors influencing it are unclear. A preliminary analysis revealed suboptimal average length of stay (ALOS) and expected length of stay (ELOS) rates - key metrics used to assess inpatient flow - across Alberta, Canada.

Safety and Real-World Effectiveness in the Transition from Alteplase to Tenecteplase for Stroke Treatment.

Background: Tenecteplase has been shown to be non-inferior to alteplase for the treatment of acute ischemic stroke within 4.5 hours of stroke onset. While not formally approved by regulatory authorities, many jurisdictions have transitioned to using tenecteplase for routine stroke treatment because it is simpler to use and has cost advantages.

Rural Field Consultation for Remote Acute Stroke Transport Decisions.

Background: The best prehospital transport strategy for patients with suspected stroke due to possible large vessel occlusion varies by jurisdiction and available resources. A foundational problem is the lack of a definitive diagnosis at the scene. Rural stroke presentations provide the most problematic triage destination decision-making.

Symptomology following COVID-19 among adults in Alberta, Canada: an observational survey study.

Objective: Fatigue, headache, problems sleeping and numerous other symptoms have been reported to be associated with long COVID. However, many of these symptoms coincide with symptoms reported by the general population, possibly exacerbated by restrictions/precautions experienced during the COVID-19 pandemic. This study examines the symptoms reported by individuals who tested positive for COVID-19 compared with those who tested negative.

Optimal Planning of Health Services through Genetic Algorithm and Discrete Event Simulation: A Proposed Model and Its Application to Stroke Rehabilitation Care.

Unlabelled: Increasing demand for provision of care to stroke survivors creates challenges for health care planners. A key concern is the optimal alignment of health care resources between provision of acute care, rehabilitation, and among different segments of rehabilitation, including inpatient rehabilitation, early supported discharge (ESD), and outpatient rehabilitation (OPR). We propose a novel application of discrete event simulation (DES) combined with a genetic algorithm (GA) to identify the optimal configuration of rehabilitation that maximizes patient benefits subject to finite health care resources.

Changes in ischemic stroke presentations, management and outcomes during the first year of the COVID-19 pandemic in Alberta: a population study.

Background: Pandemics may promote hospital avoidance, and added precautions may exacerbate treatment delays for medical emergencies such as stroke. We sought to evaluate ischemic stroke presentations, management and outcomes during the first year of the COVID-19 pandemic.

Methods: We conducted a population-based study, using linked administrative and stroke registry data from Alberta to identify all patients presenting with stroke before the pandemic (Jan.

Return on Investment in Endovascular Care: The Case of Endovascular Reperfusion Alberta.

Objective: We examined the return on investment (ROI) from the Endovascular Reperfusion Alberta (ERA) project, a provincially funded population-wide strategy to improve access to endovascular therapy (EVT), to inform policy regarding sustainability.

Methods: We calculated net benefit (NB) as benefit minus cost and ROI as benefit divided by cost. Patients treated with EVT and their controls were identified from the ESCAPE trial.

Sex Differences in Endovascular Treatment for Stroke: A Population-based Analysis.

Background: Acute ischemic stroke may affect women and men differently. We aimed to evaluate sex differences in outcomes of endovascular treatment (EVT) for ischemic stroke due to large vessel occlusion in a population-based study in Alberta, Canada.

Methods And Results: Over a 3-year period (April 2015-March 2018), 576 patients fit the inclusion criteria of our study and constituted the EVT group of our analysis.

Provincial Door-to-Needle Improvement Initiative Results in Improved Patient Outcomes Across an Entire Population.

Background And Purpose: Improving door-to-needle times (DNTs) for thrombolysis of acute ischemic stroke patients improves outcomes, but participation in DNT improvement initiatives has been mostly limited to larger, academic medical centers with an existing interest in stroke quality improvement. It is not known whether quality improvement initiatives can improve DNT at a population level, including smaller community hospitals. This study aims to determine the effect of a provincial improvement collaborative intervention on improvement of DNT and patient outcomes.

Comparative Effectiveness of Endovascular Treatment for Acute Ischemic Stroke: A Population-Based Analysis.

Background A heterogeneous patient population receives endovascular treatment (EVT) for acute ischemic stroke caused by proximal large-vessel occlusion every day. We aimed to conduct a population-based study of EVT in the province of Alberta, Canada, to understand the effectiveness in a complete population and how the magnitude of effect differs from the artificial world of clinical trials. Methods and Results Within a 3-year period (April 2015 to March 2018), 576 patients fit the inclusion criteria of our study and constituted the EVT group of our analysis.

One-Year Healthcare Utilization for Patients That Received Endovascular Treatment Compared With Control.

Background and Purpose- Endovascular therapy has been shown to be highly efficacious based on 90-day modified Rankin Scale score. We examined actual daily healthcare utilization from stroke onset to 1 year afterward from the ESCAPE trial (Endovascular Treatment for Small Core and Anterior Circulation Proximal Occlusion With Emphasis on Minimizing CT to Recanalization Time) and registry data. Methods- We examined patients from Alberta, Canada, that was enrolled into the ESCAPE trial and the Quality Improvement and Clinical Research registry in the 2016/2017 fiscal year.

Improving Door-to-needle Times in the Treatment of Acute Ischemic Stroke Across a Canadian Province: Methodology.

Background: Alteplase is a proven medical treatment for acute ischemic stroke; however, the effectiveness of this treatment is highly time dependent. Therefore, it is imperative that hospitals treat acute ischemic stroke patients as quickly as possible. The measure, door-to-needle time, is the time from hospital arrival to when alteplase administration begins.

Cost-effectiveness of home blood pressure telemonitoring and case management in the secondary prevention of cerebrovascular disease in Canada.

Home blood pressure (BP) telemonitoring and pharmacist case management reduce BP, but cost-effectiveness assessments are mixed. We examined the incremental cost-effectiveness of this intervention vs usual care in Canadians with cerebrovascular disease. A Markov decision model cost-utility analysis examining community-residing, high-risk patients with a recent nondisabling cerebrovascular event was created.

Reducing Door-to-Needle Times for Ischaemic Stroke to a Median of 30 Minutes at a Community Hospital.

Background: Alteplase is an effective treatment for ischaemic stroke patients, and it is widely available at all primary stroke centres. The effectiveness of alteplase is highly time-dependent. Large tertiary centres have reported significant improvements in their door-to-needle (DTN) times.

Health Technology Optimization Analysis: Conceptual Approach and Illustrative Application.

We present a conceptual approach to determine the optimal solution to delivering a health technology, consistent with the objective of maximizing patient outcomes subject to resources available to a publicly funded health system. The article addresses two key policy questions: 1) adding system values through appropriate planning of health services delivery and 2) considering the tradeoff between patient outcomes and costs to the health system through appropriate use of health technologies for conditions with time-dependent treatment outcomes. We develop a health technology optimization framework that considers geographical variation and searches for the best delivery method through a pairwise comparison of all possible strategies, factoring in controlled variables including disease epidemiology, time or distance to hospitals, available medical services, treatment eligibility, treatment efficacy, and costs.

Approaches to the field recognition of potential thrombectomy candidates.

Systems of care for acute ischemic stroke are being challenged to implement processes that ensure rapid access to endovascular thrombectomy. Optimizing existing regionalized stroke thrombolysis programs for endovascular thrombectomy will require accurate field recognition of treatment candidates. We begin with a review of the development of early clinical tests for ischemic stroke, illustrating challenges relevant to future field tests for large vessel occlusion.
