Comparing sources of disruptions to telemedicine-enabled stroke care in an ambulance.
This study investigated the nature and source of disruptions in an ambulance during the telemedicine-based caregiving process for stroke patients to enhance the ambulance design for supporting telemedicine-based care. Thirteen simulated telemedicine-based stroke consults were video recorded and then coded and analyzed using an existing systems-based flow disruption (FD) taxonomy. Factors that impacted disruptions included seat size, arrangement of assessment equipment, location of telemedicine equipment, and design of the telemedicine camera. The left ambulance seat zone and head of the patient bed had more environmental hazard-related disruptions, while the right zone was more prone to interruptions and communication-related disruptions.

Estimated population access to acute stroke and telestroke centers in the US, 2019.
In order to provide an update on population-level access to stroke care, the investigators estimated the proportion of the US population with access to an ED with acute stroke capabilities and assessed the specific contribution of telestroke services to US population access. They observed a substantial increase in population access to acute stroke care in this cross-sectional study relative to previous reports using alternative methods, likely due to the extensive and ongoing work to improve stroke systems of care, including greater stroke center accreditation and expansion of telestroke capacity.

An exploratory study investigating the barriers, facilitators, and demands affecting caregivers in a telemedicine integrated ambulance-based setting for stroke care.
This study investigates the impact of telemedicine on workload, teamwork, workflow, and communication of geographically distributed caregivers delivering stroke care in ambulance-based telemedicine. Simulated stroke sessions were conducted with selected caregivers, then followed with a survey and interviews. Findings showed that barriers included frustration with equipment, the loss of personal connection of the neurologists with the patients, and physical constraints in the ambulance. Facilitators included live visual communication increasing teamwork and efficiency, the ease of access to neurologist, increased flexibility, and high overall satisfaction and usability.

National trends in telestroke utilization in a US commercial platform prior to the COVID-19 pandemic.
In this study, the objective was to describe characteristics of telestroke consultations among a national sample of telestroke sites on one of the most commonly used common vendor platforms, prior to the COVID-19 public health emergency. The investigators concluded that among spoke sites using a commercial telestroke platform over a seven-year time horizon, times to consult start and alteplase bolus decreased over time. Similar to academic networks, duration of telestroke participation in this commercial network was associated with faster alteplase delivery, suggesting practice improves performance.

Improving prehospital stroke diagnosis using natural language processing of paramedic reports.
Accurate prehospital diagnosis of stroke by emergency medical services (EMS) can increase treatments rates, mitigate disability, and reduce stroke deaths. IN this study, the investigators aimed to develop a model that utilized natural language processing of EMS reports and machine learning to improve prehospital stroke identification. The investigators conducted a retrospective study of patients transported by the Chicago EMS to 17 regional primary and comprehensive stroke centers.

Emergency department telemedicine consults decrease time to interpret computed tomography of the head in a multi-network cohort.
Telemedicine can improve access to emergency stroke care in rural areas, but the benefit of telemedicine across different types and models of telemedicine networks is unknown. The objectives of this study were to (1) identify the impact of telemedicine on ED stroke care, (2) identify if telemedicine impact varied by network, and (3) describe the variation in process outcomes by telemedicine across EDs.

Regional changes in patterns of stroke presentation during the COVID-19 pandemic.
The authors sought to determine the effect of the coronavirus pandemic on patterns of stroke patient presentation and quality of care. They analyzed data from 25 New England hospitals: one urban, academic, comprehensive stroke center and telestroke hub, and 24 spoke hospitals in the same telestroke network. They included all telestroke consultations from the 24 spokes, and stroke admissions to the comprehensive stroke center hub from November 2019 through April 2020. They compared rates of presentation, timeliness presentation, and quality of care pre- versus post-March 2020. They also examined trends in patient demographics, stroke severity, timeliness, diagnosis including large vessel occlusion, alteplase use, and endovascular thrombectomy among eligible subjects. Among 1248 patient presentations, telestroke consultations and ischemic stroke patient admissions decreased through the hub and spoke network. Age and stroke severity were unchanged during the study period. However, rates of adherence for the quality measures dysphagia screening, early antithrombotic initiation, and early venous thromboembolism prophylaxis were reduced during the pandemic.

Trends in telestroke care delivery: a 15-year experience of an academic hub and its network of spokes.
Telestroke provides access to vascular neurology expertise for hospitals lacking stroke coverage, and its use has risen rapidly in the past decade. In this study the investigators aimed to characterize consultations, spoke behavior, and the relationship between spoke telestroke utilization (number of telestroke consults per year) and spoke alteplase treatment metrics in an academic telestroke network.

Evaluation of the experience of spoke hospitals in an academic telestroke network.
Implementation of telestroke has been associated with improved thrombolysis rates and clinical outcomes in remote or neurologically underserved spoke hospitals. Yet, the experience of spoke hospitals using telestroke has not been well described. In this study, the investigators sought to characterize spoke hospitals' perceptions of telestroke to understand perceived advantages, challenges, and barriers to use.

Design and implementation of structured clinical documentation support tools for treating stroke patients.
This article describes the development of a customized structured clinical documentation toolkit that standardizes patient data collection to conform to Best Practices for treating patients with stroke. The toolkit collects demographic information for patients, relevant score test measures, and information on disability, treatment, and outcomes. Basic descriptive data gathered via the toolkits is provided and their utility in collecting patient data in a manner that supports both quality clinical care and research initiatives demonstrated. Quality improvement projects and current research initiatives using the toolkit are also discussed.

Frequent hub-spoke contact is associated with improved spoke hospital performance: results from the Massachusetts General Hospital Telestroke Network.
This study investigated the association of a strong hub-spoke hospital connection with improved spoke hospital performance for acute ischemic stroke patients associated with the Massachusetts General Hospital Telestroke Network. Investigators identified 375 patients treated with tPA by conventional or telestroke methods from 2006-2015 with 16 spoke hospitals. There was a positive association between more frequent contact between a telestroke spoke and its hub and faster tPA delivery for patients.

A mHealth-based care model for improving hypertension control in stroke survivors: pilot RCT.
Hypertension (HTN) is significantly under-treated in stroke survivors. The study authors examined usability and efficacy of a mHealth -based care model for improving post-stroke HTN control. They concluded that a mHealth-based HTN care model had excellent usability and provided better HTN control than usual care in stroke survivors.
