Abstract
Stroke is one of the most common acute neurological disorders and a leading cause of disability worldwide. Evidence-based treatments over the last two decades have driven a revolution in the clinical management and design of stroke services. We need a highly skilled, multidisciplinary workforce that includes neurologists as core members to deliver modern stroke care. In the UK, the dedicated subspecialty training programme for stroke medicine has recently been integrated into the neurology curriculum. All neurologists will be trained to contribute to each aspect of the stroke care pathway. We discuss how training in stroke medicine is evolving for neurologists and the opportunities and challenges around practising stroke medicine in the UK and beyond.

The role of stroke care infrastructure on the effectiveness of a hub-and-spoke telestroke model in South Carolina. J Stroke Cerebrovasc Dis 2024; 33:107702. [PMID: 38556068 PMCID: PMC11088489 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Revised: 03/21/2024] [Accepted: 03/28/2024] [Indexed: 04/02/2024] Open
Abstract
OBJECTIVE To examine the relationship between stroke care infrastructure and stroke quality-of-care outcomes at 29 spoke hospitals participating in the Medical University of South Carolina (MUSC) hub-and-spoke telestroke network. MATERIALS AND METHODS Encounter-level data from MUSC's telestroke patient registry were filtered to include encounters during 2015-2022 for patients aged 18 and above with a clinical diagnosis of acute ischemic stroke, and who received intravenous tissue plasminogen activator. Unadjusted and adjusted generalized estimating equations assessed associations between time-related stroke quality-of-care metrics captured during the encounter and the existence of the two components of stroke care infrastructure-stroke coordinators and stroke center certifications-across all hospitals and within hospital subgroups defined by size and rurality. RESULTS Telestroke encounters at spoke hospitals with stroke coordinators and stroke center certifications were associated with shorter door-to-needle (DTN) times (60.9 min for hospitals with both components and 57.3 min for hospitals with one, vs. 81.2 min for hospitals with neither component, p <.001). Similar patterns were observed for the percentage of encounters with DTN time of ≤60 min (63.8% and 68.9% vs. 32.0%, p <.001) and ≤45 min (34.0% and 38.4% vs. 8.42%, p <.001). Associations were similar for other metrics (e.g., door-to-registration time), and were stronger for smaller (vs. larger) hospitals and rural (vs. urban) hospitals. CONCLUSIONS Stroke coordinators or stroke center certifications may be important for stroke quality of care, especially at spoke hospitals with limited resources or in rural areas.

Abstract
INTRODUCTION Telemedicine can alleviate the problems faced in rural settings in providing access to specialist stroke care. The evidence of the cost-effectiveness of this model of care outside high-income countries is limited. This study aimed to conduct: (a) a systematic review of economic evaluations of telestroke and (b) a cost-utility analysis of telestroke, using China as a case study. METHODS We systematically searched Embase, Medline Complete and Cochrane databases. Inclusion criteria: full economic evaluations of telemedicine/telestroke networks examining the use of thrombolysis in patients with acute ischaemic stroke, published in English. A cost-utility analysis was undertaken using a Markov model incorporating a decision tree to simulate the delivery of telestroke for acute ischaemic stroke in rural China, compared to no telestroke from a societal and healthcare perspective. One-way deterministic sensitivity analyses and probabilistic sensitivity analyses were performed to test the robustness of results. RESULTS Of 559 publications found, eight met the eligibility criteria and were included in the systematic review (two cost-effectiveness analyses and six cost-utility analyses, all performed in high-income countries). Telestroke was a cost-saving/cost-effective intervention in five out of the eight studies. In our modelled analysis for rural China, telestroke was the dominant strategy, with estimated cost savings of Chinese yuan 4,328 (US$627) and additional 0.0925 quality-adjusted life years per patient. Sensitivity analyses confirmed the base case results. DISCUSSION Consistent with published economic evaluations of telestroke in other jurisdictions, telestroke represents a cost-effective solution to enhance stroke care in rural China.

Abstract
BACKGROUND Efficient transfer to mechanical thrombectomy (MT)-capable centers is essential for patients with stroke. Weather may influence stroke risk, transportation, and outcomes. OBJECTIVE To investigate how weather affects stroke patient transfer and outcomes after MT. METHODS We retrospectively collected data for patients with stroke transferred from spoke to our hub hospital to undergo MT between 2017 and 2021. We examined associations between weather, transportation, and patient outcomes. RESULTS We included 543 patients with a mean age of 71.7 years. The median National Institutes of Health Stroke Score increased from 14 to 15 after transportation. The median modified Rankin Scale was 4 at discharge and 90 days, and 3 at the final follow-up (mean 91.7 days). Higher daily temperatures were associated with good outcome, whereas daily drizzle was associated with poor outcome. More patients were transferred by air when visibility was better, and by ground during heavier precipitation, higher humidity, rain, mist, and daily drizzle, fog, and thunder . Patient outcomes were not associated with transportation mode. Among the independent predictors of good outcome, none was a weather variable. Lower hourly relative humidity ( P = .003) and longer road distance ( P < .001) were independent predictors of using air transportation, among others. CONCLUSION During transportation, higher temperature was associated with good outcome, whereas daily drizzle was associated with poor outcome after MT. Although weather was associated with transportation mode, no differences in outcomes were found between transportation modes. Further studies are needed to modify transfer protocols, especially during cold and rainy days, and potentially improve outcomes.

Abstract
There is constant evolution in the diagnosis and treatment of acute ischemic stroke due to advances in treatments, imaging, and outreach. Two major revolutions were the advent of intravenous thrombolysis in the 1990s and endovascular thrombectomy in 2010s. Neuroimaging approaches have also evolved with key goals-detect hemorrhage, augment thrombolysis treatment selection, detect arterial occlusion, estimate infarct core, estimate viable penumbra, and augment thrombectomy treatment selection. The ideal approach to diagnosis and treatment may differ depending on the system of care and available resources. Future directions include expanding indications for these treatments, including a shift from time-based to tissue-based selection.

Abstract
A teleneurology hospitalist model aims to address the demand for high-quality neurologic acute care and the shortage of neurologists. Here, we review concepts and models of teleneurology services to address access and care gaps in neurology beyond telestroke models. The goal of these emergent teleservices is to empower community hospitals to deliver the highest quality care, while also reducing unnecessary patient transfers to tertiary care hospitals. We highlight the clinical models, patient populations, and innovative approaches of different tele-neurohospitalist services. This includes challenges related to clinical limitations, legal issues, and reimbursement. We highlight specific areas of research that can further clarify and refine the appropriate use, cost-effectiveness, and clinical outcomes of these telemedicine-based care models.

Abstract
BACKGROUND AND OBJECTIVES Despite the dramatic increase in the provision of virtual nephrology care, only anecdotal reports of outcomes without comparators to usual care exist in the literature. This study aimed to provide objective determination of clinical noninferiority of hybrid (telenephrology plus face-to-face) versus standard (face-to-face) inpatient nephrology care. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This retrospective study compares objective outcomes in patients who received inpatient hybrid care versus standard nephrology care at two Mayo Clinic Health System community hospitals. Outcomes were then additionally compared with those patients receiving care at another Mayo Clinic Health System site where only standard care is available. Hospitalized adults who had nephrology consults from March 1, 2020 to February 28, 2021 were considered. Regression was used to assess 30-day mortality, length of hospitalization, readmissions, odds of being prescribed dialysis, and hospital transfers. Sensitivity analysis was performed using patients who had ≥50% of their care encounters via telenephrology. Structured surveys were used to understand the perspectives of non-nephrology hospital providers and telenephrologists. RESULTS In total, 850 patients were included. Measured outcomes that included the number of hospital transfers (odds ratio, 1.19; 95% confidence interval, 0.37 to 3.82) and 30-day readmissions (odds ratio, 0.97; 95% confidence interval, 0.84 to 1.06), among others, did not differ significantly between controls and patients in the general cohort. Telenephrologists (n=11) preferred video consults (82%) to phone for communication. More than half (64%) of telenephrologists spent less time on telenephrology compared with standard care. Non-nephrology hospital providers (n=21) were very satisfied (48%) and satisfied (29%) with telenephrology response time and felt telenephrology was as safe as standard care (67%), while providing them enough information to make patient care decisions (76%). CONCLUSIONS Outcomes for in-hospital nephrology consults were not significantly different comparing hybrid care versus standard care. Non-nephrology hospital providers and telenephrologists had favorable opinions of telenephrology and most perceived it is as safe and effective as standard care.

Abstract
The application of telestroke has matured considerably since its inception in 1999. The use of telestroke is now recommended in several published guidelines. Consequently, jurisdictions without a telestroke service are seeking practical information on the best approach to implement telestroke. French et al. (2013) reviewed the challenges of implementing a telestroke network including studies between 2000 and 2010. At the time, telestroke networks were largely limited to the UK, USA, Canada and Europe and only one process evaluation had been conducted. Given the prolific expansion of telestroke services since 2010, we conducted a systematic review to determine factors associated with successful establishment, management, and sustainability of a contemporary telestroke services. A comprehensive search of telestroke studies was conducted in July 2021. Empirical studies published between 2010 and 2021 were included if they contained descriptive, evaluation or operational data on the implementation of a telestroke network. Studies were subsequently evaluated using the Consolidated Framework for Implementation Research (CFIR). The initial literature search revealed a total of 7415 potential studies; 38 of which met the inclusion criteria. The past decade of process evaluation studies has enabled a more nuanced investigations into how to implement and sustain a telestroke network. Pre-implementation planning is crucial to ensure clear telestroke processes, governance structures and stakeholder engagement. Sustainability of networks relies on securing long-term investment, providing adequate resources, and maintaining staff motivation and willingness. Recommendations are provided to overcome commonly identified barriers related to technology, staffing, planning and standardisation of processes, evaluation, and sustainability and scale-up. Further research needs to explore how new advancements in stroke care such as endovascular clot retrieval (EVT) and advanced brain imaging can be considered and planned for during the implementation of a new telestroke service.

Abstract
Objective In 2020, the coronavirus disease 2019 (COVID-19) pandemic exposed existing stressors in the neurosurgical care infrastructure in the United States. We aimed to detail innovative technologic solutions inspired by the pandemic-related restrictions that augmented neurosurgical education and care delivery. Methods Several digital health and audiovisual innovations were implemented, including use of remote video technology to facilitate inpatient consultations and outpatient ambulatory virtual visits, optimize regional hospital neurosurgical coverage, expand interdisciplinary patient management conferences (i.e., tumor board), and further enhance the neurosurgical resident education program. Enterprise patient experience data were queried to evaluate patient satisfaction following the switch to virtual visits. Results Between January 2020 and April 2021, use of virtual visits more than doubled in the Department of Neurosurgery. A survey of 10,772 patients following ambulatory visits showed that virtual visits were equal if not better in providing satisfactory patient care than in-person visits. After switching our interdisciplinary spine tumor board to a virtual meeting, we increased surgeon participation and attendance by 49.29%. Integration of remote audiovisual technology in resident didactics and clinical training improved our ability to provide comprehensive and personalized educational experiences our trainees. Conclusions Digital health technology has improved neurosurgical care and comprehensive training at our institution. Investment in the technologic infrastructure required for these remote audiovisual services during the COVID-19 pandemic will facilitate the expansion of neurosurgical care provision for patients across the United States in the future. Governing bodies within organized neurosurgery should advocate for the continued financial and licensing support of these service on a national fiscal and policy level.

Abstract
Importance Telestroke is increasingly used in hospital emergency departments, but there has been limited research on its impact on treatment and outcomes. Objective To describe differences in care patterns and outcomes among patients with acute ischemic stroke who present to hospitals with and without telestroke capacity. Design, Setting, and Participants Patients with acute ischemic stroke who first presented to hospitals with telestroke capacity were matched with patients who presented to control hospitals without telestroke capacity. All traditional Medicare beneficiaries with a primary diagnosis of acute ischemic stroke (approximately 2.5 million) who presented to a hospital between January 2008 and June 2017 were considered. Matching was based on sociodemographic and clinical characteristics, hospital characteristics, and month and year of admission. Hospitals included short-term acute care and critical access hospitals in the US without local stroke expertise. In 643 hospitals with telestroke capacity, there were 76 636 patients with stroke who were matched 1:1 to patients at similar hospitals without telestroke capacity. Data were analyzed in July 2020. Main Outcomes and Measures Receipt of reperfusion treatment through thrombolysis with alteplase or thrombectomy, mortality at 30 days from admission, spending through 90 days from admission, and functional status as measured by days spent living in the community after discharge. Results In the final sample of 153 272 patients, 88 386 (57.7%) were female, and the mean (SD) age was 78.8 (10.4) years. Patients cared for at telestroke hospitals had higher rates of reperfusion treatment compared with those cared for at control hospitals (6.8% vs 6.0%; difference, 0.78 percentage points; 95% CI, 0.54-1.03; P < .001) and lower 30-day mortality (13.1% vs 13.6%; difference, 0.50 percentage points; 95% CI, 0.17-0.83, P = .003). There were no differences in days spent living in the community following discharge or in spending. Increases in reperfusion treatment were largest in the lowest-volume hospitals, among rural residents, and among patients 85 years and older. Conclusions and Relevance Patients with ischemic stroke treated at hospitals with telestroke capacity were more likely to receive reperfusion treatment and have lower 30-day mortality.

CTA Protocols in a Telestroke Network Improve Efficiency for Both Spoke and Hub Hospitals. AJNR Am J Neuroradiol 2021; 42:435-440. [PMID: 33541900 DOI: 10.3174/ajnr.a6950] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Accepted: 10/03/2020] [Indexed: 12/29/2022]
Abstract
BACKGROUND AND PURPOSE Telestroke networks support screening for patients with emergent large-vessel occlusions who are eligible for endovascular thrombectomy. Ideal triage processes within telestroke networks remain uncertain. We characterize the impact of implementing a routine spoke hospital CTA protocol in our integrated telestroke network on transfer and thrombectomy patterns. MATERIALS AND METHODS A protocol-driven CTA process was introduced at 22 spoke hospitals in November 2017. We retrospectively identified prospectively collected patients who presented to a spoke hospital with National Institutes of Health Stroke Scale scores ≥6 between March 1, 2016 and March 1, 2017 (pre-CTA), and March 1, 2018 and March 1, 2019 (post-CTA). We describe the demographics, CTA utilization, spoke hospital retention rates, emergent large-vessel occlusion identification, and rates of endovascular thrombectomy. RESULTS There were 167 patients pre-CTA and 207 post-CTA. The rate of CTA at spoke hospitals increased from 15% to 70% (P < .001). Despite increased endovascular thrombectomy screening in the extended window, the overall rates of transfer out of spoke hospitals remained similar (56% versus 54%; P = .83). There was a nonsignificant increase in transfers to our hub hospital for endovascular thrombectomy (26% versus 35%; P = .12), but patients transferred >4.5 hours from last known well increased nearly 5-fold (7% versus 34%; P < .001). The rate of endovascular thrombectomy performed on patients transferred for possible endovascular thrombectomy more than doubled (22% versus 47%; P = .011). CONCLUSIONS Implementation of CTA at spoke hospitals in our telestroke network was feasible and improved the efficiency of stroke triage. Rates of patients retained at spoke hospitals remained stable despite higher numbers of patients screened. Emergent large-vessel occlusion confirmation at the spoke hospital lead to a more than 2-fold increase in thrombectomy rates among transferred patients at the hub.

Abstract
During the COVID-19 pandemic, one of the major changes that has occurred in emergency medicine is the evolution of telemedicine. With relaxation of regulatory and administrative barriers, the use of this already available technology has rapidly expanded. Telemedicine provides opportunity to markedly decrease personal protective equipment (PPE) and reduce healthcare worker exposures. Moreover, with the convenience and availability of access to medical care via telemedicine, a more fundamental change in healthcare delivery in the United States is likely. The implementation of telemedicine in the emergency department (ED) in particular has great potential to prevent the iatrogenic spread of COVID-19 and protect health care workers. Challenges to widespread adoption of telemedicine include privacy concerns, limitation of physical examination, and concerns of patient experience. In this clinical review, we discuss ED telemedicine applications, logistics, and challenges in the COVID-19 era as well as recent regulatory and legal changes. In addition, examples of telemedicine use are described from 2 institutions. Examples of future applications of telemedicine within the realm of emergency medicine are also discussed.

Abstract
Stroke is the second leading cause of death and a major contributor to disability worldwide. The prevalence of stroke is highest in developing countries, with ischemic stroke being the most common type. Considerable progress has been made in our understanding of the pathophysiology of stroke and the underlying mechanisms leading to ischemic insult. Stroke therapy primarily focuses on restoring blood flow to the brain and treating stroke-induced neurological damage. Lack of success in recent clinical trials has led to significant refinement of animal models, focus-driven study design and use of new technologies in stroke research. Simultaneously, despite progress in stroke management, post-stroke care exerts a substantial impact on families, the healthcare system and the economy. Improvements in pre-clinical and clinical care are likely to underpin successful stroke treatment, recovery, rehabilitation and prevention. In this review, we focus on the pathophysiology of stroke, major advances in the identification of therapeutic targets and recent trends in stroke research.

[PMID: 32992169 DOI: 10.1016/j.jstrokecerebrovasdis.2020.105310] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Revised: 08/18/2020] [Accepted: 09/06/2020] [Indexed: 12/20/2022] Open
Abstract
OBJECTIVE Although many emergency departments (EDs) have telestroke capacity, it is unclear why some EDs consistently use telestroke and others do not. We compared the characteristics and practices of EDs with robust and low assimilation of telestroke. METHODS We conducted semi-structured interviews with representatives of EDs that received telestroke services from 10 different networks and had used telestroke for a minimum of two years. We used maximum diversity sampling to select EDs for inclusion and applied a positive deviance approach, comparing programs with robust and low assimilation. Data collection was informed by the Consolidated Framework for Implementation Research. For the qualitative analysis, we created site summaries and conducted a supplemental matrix analysis to identify themes. RESULTS Representatives from 21 EDs with telestroke, including 11 with robust assimilation and 10 with low assimilation, participated. In EDs with robust assimilation, telestroke workflow was highly protocolized, programs had the support of leadership, telestroke use and outcomes were measured, and individual providers received feedback about their telestroke use. In EDs with low assimilation, telestroke was perceived to increase complexity, and ED physicians felt telestroke did not add value or had little value beyond a telephone consult. EDs with robust assimilation identified four sets of strategies to improve assimilation: strengthening relationships between stroke experts and ED providers, improving and standardizing processes, addressing resistant providers, and expanding the goals and role of the program. CONCLUSION Greater assimilation of telestroke is observed in EDs with standardized workflow, leadership support, ongoing evaluation and quality improvement efforts, and mechanisms to address resistant providers.

Trends Among Rural and Urban Medicare Beneficiaries in Care Delivery and Outcomes for Acute Stroke and Transient Ischemic Attacks, 2008-2017. JAMA Neurol 2020; 77:863-871. [PMID: 32364573 PMCID: PMC7358912 DOI: 10.1001/jamaneurol.2020.0770] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Accepted: 02/21/2020] [Indexed: 12/20/2022]
Abstract
Importance Over the last decade or so, there have been substantial investments in the development of stroke systems of care to improve access and quality of care in rural communities. Whether these have narrowed rural-urban disparities in care is unclear. Objective To describe trends among rural and urban patients with acute ischemic stroke or transient ischemic attack in the type of health care centers to which patients were admitted, what care was provided, and the outcomes patients experienced. Design, Setting, and Participants This descriptive observational study included 100% claims for beneficiaries of traditional fee-for-service Medicare from 2008 through 2017. All rural and urban areas in the US were included, defined by whether a beneficiary's residential zip code was in a metropolitan or nonmetropolitan area. All admissions in the US among patients with traditional Medicare who had a transient ischemic attack or acute stroke (N = 4.01 million) were eligible to be included in this study. Admissions for beneficiaries with end-stage kidney disease (n = 85 927 [2.14%]), beneficiaries with unidentified Rural-Urban Commuting Area codes (n = 12 797 [0.32%]), and beneficiaries not continuously enrolled in traditional Medicare in the 12 months before and 3 months after their admission (n = 442 963 [11.0%]) were excluded. Exposures Residence in an urban or rural area; admission to a hospital with a transient ischemic attack or acute stroke. Main Outcomes and Measures Discharge from a certified stroke center, receiving a neurology consultation during admission, treatment with alteplase, days institutionalized, and 90-day mortality. Results The final sample included 3.47 million admissions from 2008 through 2017. In this sample, 2.01 million patients (58.0%) were female, and the mean (SD) age was 78.6 (10.5) years. In 2008, 24 681 patients (25.2%) and 161 217 patients (60.6%) in rural and urban areas, respectively, were cared for at a certified stroke center (disparity, -35.4%). By 2017, this disparity was -26.6%, having narrowed by 8.7 percentage points (95% CI, 6.6-10.8 percentage points). There was also narrowing in the rural-urban disparity in neurologist evaluation during admission (6.3% [95% CI, 4.2%-8.4%]). However, the rural-urban disparity widened or was similar with regard to receiving alteplase (0.5% [95% CI, 0.1%-0.8%]), mean days in an institution from admission (0.5 [95% CI, 0.2-0.8] days), and mortality at 90 days (0.3% [95% CI, -0.02% to 0.6%]), respectively. Conclusions and Relevance In the last decade, care for rural residents with acute ischemic stroke and transient ischemic attack has shifted to certified stroke centers and now more likely includes neurologist input. However, disparities in access to treatments, such as alteplase, and outcomes persist, highlighting that work still is needed to extend improvements in stroke care to all US residents.

Abstract
Concussion is a form of mild traumatic brain injury that affects thousands of Canadian children and adolescents annually. Despite national efforts to harmonize the recognition and management of pediatric concussion in Canada, timely access to primary and specialized care following this injury remains a challenge for many patients especially those who live in rural and remote communities. To address similar challenges facing patients with stroke and other neurological disorders, physicians have begun to leverage advances in telemedicine to improve the delivery of specialized neurological care to those living in medically underserved regions. Preliminary studies suggest that telemedicine may be a safe and cost-effective approach to assist in the medical care of select patients with acute concussion and persistent post-concussion symptoms. Here we provide an overview of telemedicine, teleneurology, the principles of concussion assessment and management, as well as the current state of concussion care in Canada. Utilizing preliminary evidence from studies of telemedicine in concussion and experience from comprehensive systems of care for stroke, we outline steps that must be taken to evaluate the potential of telemedicine-based concussion networks to improve the care of pediatric concussion patients living in underserved rural and remote communities in Canada.

Abstract
Older people present with complex health issues on admission to hospital and are at high risk for functional decline and related complications. Thus, they require the services of diverse health-care professionals working in concert to support their functioning. Despite nurses' central role in caring for this patient population, and evidence indicating that interprofessional communication is a persistent challenge for nurses in acute-care settings, little is known about nurses' views on interprofessional communication in care preserving functioning in acutely admitted older people. To fill this knowledge gap, we gathered acute-care staff nurses' perspectives on interprofessional communication in a function-focused, interprofessional approach to hospital care for older adults. Thirteen focus groups were conducted with a purposeful, criterion-based sample of 57 nurses working in acute-care hospitals. Thematic analysis revealed two overarching themes capturing nurses' perspectives on key factors shaping interprofessional communication in a function-focused interprofessional approach to care (1) context of direct communication and (2) context of indirect communication. The first theme demonstrates that nurses preferred synchronous modes of communication, but some ascribed greater importance to unstructured forms of direct information-sharing, while others stressed structured direct communication, particularly interprofessional rounds. The second theme also documents divergence in nurses' views on asynchronous communication, with some emphasizing information technology and others analog tools. Perceptions of some modes of interprofessional communication were found to vary by practice setting. Theoretical and pragmatic conclusions are drawn that can be used to optimize interprofessional communication processes supporting hospitalized older people's functioning.

Abstract
BackgroundDebate continues as to whether patients with acute ischemic stroke with (suspected) large vessel occlusion benefit from direct referral versus secondary transportation.AimsTo analyze the change in early infarct signs, collaterals, and acute ischemia volume and their association with transfer time and functional outcome.MethodsWe retrospectively analyzed consecutive transfers between 2013 and 2016 for patients with anterior circulation stroke transported from referring hospitals to our center as potential candidates for thrombectomy. Alberta Stroke Programme Early CT Scores (ASPECTS) were automatically calculated on external and in-house CT using the Brainomix e-ASPECTS software, and collaterals were assessed using the e-CTA tool. Functional status after stroke using the modified Rankin scale (mRS) was obtained.Results102 patients with CT scans both at the referring hospital and our center were identified. During patient transfer, e-ASPECTS declined by a median of 1 point (0–2). Functional outcome correlated with the change in e-ASPECTS (decline, n=54) (Spearman rs=0.322, 95% CI 0.131 to 0.482, p=0.001). The median image-to-image time was 149 min (IQR 113–190), but did not correlate with change in e-ASPECTS (p=0.754) and mRS score at 3 months (p=0.25). Preserved good collateral status assessed at the comprehensive stroke center was associated with better functional outcome (rs=−0.271, 95% CI −0.485 to −0.037, p=0.02).ConclusionsPatient transfer in a drip-and-ship network was associated with declines in e-ASPECTS associated with worse functional outcome. Image-to-image time did not influence this association, but worsening collateral status did.

Abstract
BACKGROUND Intravenous thrombolysis has been recently introduced in Nepal for the management of acute ischemic stroke. Pre-hospital delay is one of the main reasons that hinder thrombolytic therapy. The objective of this study was to evaluate the status of prehospital delay and thrombolysis in Nepal. METHODS Data were prospectively collected from patients of both genders, age > 18 years who arrived at the emergency department (ED) with symptoms and neuroimaging findings consistent with an ischemic stroke. Patient data were obtained from ED form and standard questionnaires were used to assess factors resulting in prehospital delay. Modified Rankin scale and National Institute of Health stroke scale were used to assess the degree of disability and severity of stroke respectively. RESULTS A total of 228 patients were enrolled in the study between August 2017 and August 2018. Only 46 (20.17%) patients arrived within the time frame for thrombolysis. Onset at daytime (OR: 4.07; 95% CI: 1.65-10.1; p = 0.001), stroke symptoms facial deviation (OR: 5.03; 95% CI: 2.47 to 10.26; p = 0.000) and speech disturbances (OR: 2.34; 95% CI: 1.06 to 5.1; p = 0.021), identification of stroke (OR: 22.36; 95% CI: 9.42-53.04;p = 0.000), rushing to ED after onset of symptoms (OR: 2.93; 95% CI: 1.5-5.7; p = 0.001), awareness of treatment of stroke (OR: 10.21; 95% CI: 4.8-21.6; p = 0.000), direct presentation (OR: 4.2; 95% CI: 2.09-8.66; p = 0.000), the distance less than 20 km (OR: 7.9; 95% CI: 3.8-16.5; p = 0.000), and education above high school (OR:4.85; 95% CI: 2.2-10.5; p = 0.000) were associated with early arrival. Heavy traffic, income below 1000 USD per annum and diabetes mellitus were associated with delayed arrival to ED. Out of 46 early arrival patients, only 30 patients (13.15%) received tissue plasminogen activator during the study period, while others were deprived because of their inability to afford the treatment cost. CONCLUSION Community-based intervention to spread awareness, establishing comprehensive stroke centers, training specialists, improving emergency services, establishment of telestroke facilities and encouraging the use of low-cost tenecteplase as an alternative to alteplase can help improve care for stroke patients in Nepal.

Abstract
BackgroundWith the benefit of mechanical thrombectomy firmly established, the focus has shifted to improved delivery of care. Reducing time from symptom onset to reperfusion is a primary goal. Technology promises tremendous opportunities in the prehospital space to achieve this goal.MethodsThis review explores existing, fledgling, and potential future technologies for application in the prehospital space.ResultsThe opportunity for technology to improve stroke care resides in the detection, evaluation, triage, and transport of patients to an appropriate healthcare facility. Most prehospital technology remains in the early stages of design and implementation.ConclusionThe major challenges to tackle for future improvement in prehospital stroke care are that of public awareness, emergency medical service detection, and triage, and improved systems of stroke care. Thoughtfully applied technology will transform all these areas.

[PMID: 30619062 PMCID: PMC6305592 DOI: 10.3389/fneur.2018.01106] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Accepted: 12/03/2018] [Indexed: 12/04/2022] Open
Abstract
Introduction: The weekend effect is a well-recognized phenomenon in which patient outcomes worsen for acute strokes presenting outside routine business hours. This is attributed to non-uniform availability of services throughout the week and evenings and, though described for intravenous thrombolysis candidates, is poorly understood for endovascular stroke care. We evaluated the impact of institutional protocols on the weekend effect, and the speed and outcome of endovascular therapy as a function of time of presentation. Method: This study assesses a prospective observational cohort of 129 consecutive patients. Patients were grouped based on the time of presentation during regular work hours (Monday through Friday, 07:00–19:00 h) vs. off-hours (overnight 19:00–07:00 h and weekends) and assessed for treatment latency and outcome. Results: Treatment latencies did not depend on the time of presentation. The door to imaging interval was comparable during regular and off-hours (median time 21 vs. 19 min, respectively, p < 0.50). Imaging to groin puncture was comparable (71 vs. 71 min, p < 1.0), as were angiographic and functional outcomes. Additionally, treatment intervals decreased with increased protocol experience; door-to-puncture interval significantly decreased from the first to the fourth quarters of the study period (115 vs. 94 min, respectively, p < 0.006), with the effect primarily seen during off-hours with a 28% reduction in median door-to-puncture times. Conclusions: Institutional protocols help diminish the weekend effect in endovascular stroke treatment. This is driven largely by improvement in off-hours performance, with protocol adherence leading to further decreases in treatment intervals over time.

Abstract
Background Traditionally, patients undergoing acute ischemic strokes were candidates for mechanical thrombectomy if they were within the 6-h window from onset of symptoms. This timeframe would exclude many patient populations, such as wake-up strokes. However, the most recent clinical trials, DAWN and DEFUSE3, have expanded the window of endovascular treatment for acute ischemic stroke patients to within 24 h from symptom onset. This expanded window increases the number of potential candidates for endovascular intervention for emergent large vessel occlusions and raises the question of how to efficiently screen and triage this increase of patients. Summary Abbreviated pre-hospital stroke scales can be used to guide EMS personnel in quickly deciding if a patient is undergoing a stroke. Telestroke networks connect remote hospitals to stroke specialists to improve the transportation time of the patient to a comprehensive stroke center for the appropriate level of care. Mobile stroke units, mobile interventional units, and helistroke reverse the traditional hub-and-spoke model by bringing imaging, tPA, and expertise to the patient. Smartphone applications and social media aid in educating patients and the public regarding acute and long-term stroke care. Key Messages The DAWN and DEFUSE3 trials have expanded the treatment window for certain acute ischemic stroke patients with mechanical thrombectomy and subsequently have increased the number of potential candidates for endovascular intervention. This expansion brings patient screening and triaging to greater importance, as reducing the time from symptom onset to decision-to-treat and groin puncture can better stroke patient outcomes. Several strategies have been employed to address this issue by reducing the time of symptom onset to decision-to-treat time.

Functional Outcome Measures of Recombinant Tissue Plasminogen Activator-Treated Stroke Patients in the Telestroke Technology. J Exp Neurosci 2018; 12:1179069518793412. [PMID: 30245570 PMCID: PMC6144501 DOI: 10.1177/1179069518793412] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2018] [Accepted: 07/12/2018] [Indexed: 11/16/2022] Open
Abstract
The efficiency of telestroke programs in improving the rates of recombinant
tissue plasminogen activator (rtPA) in stroke patients has been reported.
Previous studies have reported favorable treatment outcomes with the use of
telestroke programs to improve the use of rtPA, but functional outcomes are not
fully understood. This study investigated the effect of telestroke technology in
the administration of rtPA and related functional outcomes associated with
baseline clinical variables. Retrospective data of a telestroke registry were
analyzed. Univariate analysis was used to compare demographic and clinical
variables in the rtPA group and the no rtPA group and between the improved
functional ambulation group and the no improvement group. A stepwise binary
logistic regression identified factors associated with improved functional
outcome in the total telestroke population and in the subset of the telestroke
population who received rtPA. In adjusted analysis and elimination of any
multicollinearity for patients who received rtPA in the telestroke setting,
obesity (odds ratio [OR] = 2.138, 95% confidence interval [CI], 1.164-3.928,
P < .05), higher systolic blood pressure at the time of
presentation (OR = 1.015, 95% CI, 1.003-1.027, P < .05), and
baseline high-density lipoprotein at the time of admission (OR = 1.032, 95% CI,
1.005-1.059, P < .05) were associated with improved
functional outcomes. Increasing age (OR = 0.940, 95% CI, 0.916-0.965,
P < .0001) and higher calculated National Institutes of
Health Stroke Scale (OR = 0.903, 95% CI, 0.869-0.937) were associated with a
poorer outcome in rtPA-treated patients. Telestroke technology improves
functional outcomes at spoke stations where neurological expertise is
unavailable. Further studies are necessary to determine how telestroke
technology can be optimized, especially to improve contraindications and
increase eligibility for thrombolysis therapy.

Abstract
PURPOSE OF REVIEW The management of patients with acute stroke has been revolutionized in recent years with the advent of new effective treatments. In this rapidly evolving field, we provide an update on the management of acute stroke excluding thrombectomy, looking to recent, ongoing, and future trials. RECENT FINDINGS Large definitive trials have provided insight into acute stroke care including broadening the therapeutic window for thrombolysis, alternatives to standard dose alteplase, the use of dual antiplatelet therapy early after minor ischemic stroke, and treating elevated blood pressure in intracerebral hemorrhage. Further ongoing and future trials are eagerly awaited in this ever-expanding area. Although definitive trials have led to improvements in acute stroke care, there remains a need for further research to improve our understanding of pathophysiological mechanisms underlying different stroke types with the potential for treatments to be tailored to the individual.

Abstract
INTRODUCTION Amyotrophic lateral sclerosis (ALS) patients benefit from multidisciplinary care in an ALS clinic. We studied whether multidisciplinary care of ALS patients using the store and forward method of telemedicine was feasible and acceptable to patients and providers. METHODS ALS patients seen in the University of Florida (UF) Jacksonville ALS clinic were eligible for our study. A trained telemedicine nurse performed and recorded a multidisciplinary assessment of the patient in their home. Clinic team members reviewed the assessments and provided recommendations, and the clinic director discussed the plan with the patient via videoconference. Patient and provider satisfaction was evaluated using surveys. RESULTS Eighteen patients completed a total of 27 telemedicine visits. Patient satisfaction was excellent and provider satisfaction was very good. DISCUSSION The store and forward method of telemedicine is an acceptable alternative to live telemedicine for the multidisciplinary care of ALS patients. This method of care may improve access to multidisciplinary care for this patient population. Muscle Nerve 59:34-39, 2019.

Abstract
BACKGROUND While an explosion in technological sophistication has revolutionized surgery within the operating theatre, delivery of surgical ward-based care has seen little innovation. Use of telepresence allowing off-site clinicians communicate with patients has been largely restricted to outpatient settings or use of complex, expensive, static devices. We designed a prospective study to ascertain feasibility and face validity of a remotely controlled mobile audiovisual drone (LUCY) to access inpatients. This device is, uniquely, lightweight, freely mobile and emulates 'human' interaction by swiveling and adjusting height to patients' eye-level. METHODS: Robot-assisted ward rounds(RASWR) were conducted over 3 months. A remotely located consultant surgeon communicated with patients/bedside teams via encrypted audiovisual telepresence robot (DoubleRoboticstm, California USA). Likert-scale satisfaction questionnaires, incorporating free-text sections for mixed-methods data collection, were disseminated to patient and staff volunteers following RASWRs. The same cohort completed a linked questionnaire following conventional (gold-standard) rounds, acting as control group. Data were paired, and non-parametric analysis performed. RESULTS: RASWRs are feasible (>90% completed without technical difficulty). The RASWR(n=52 observations) demonstrated face validity with strong correlations (r>0.7; Spearman, p-value <0.05) between robotic and conventional ward rounds among patients and staff on core themes, including dignity/confidentiality/communication/satisfaction with management plan. Patients (96.08%, n=25) agreed RASWR were a satisfactory alternative when consultant physical presence was not possible. There was acceptance of nursing/NCHD cohort (100% (n=11) willing to regularly partake in RASWR). CONCLUSION: RASWRs receive high levels of patient and staff acceptance, and offer a valid alternative to conventional ward rounds when a consultant cannot be physically present.

Abstract
BACKGROUND AND PURPOSE For suspected large vessel occlusion patients efficient transfer to centers that provide endovascular therapy (ET) is critical to maximizing treatment opportunity. Our objective was to examine associations between transfer time, modes of transfer, ET, and outcomes within a hub-and-spoke telestroke network. METHODS Patients with ischemic stroke were included if transferred to a single hub hospital between January 2011 and October 2015 with National Institutes of Health Stroke Scale>6, onset<12 hours from hub arrival with complete clinical, imaging, and transfer data. Transfer time was the interval between initiation of telestroke consult and arrival at the hub. Algorithms were created for ideal transfer times; ideal time was subtracted from actual time to calculate delay. We examined bivariate relationships between transfer time and several clinical outcomes and used multivariable regression modeling to explore possible predictors of delay. RESULTS Of 234 patients that met inclusion criteria, 51% were transferred by ambulance and 49% by helicopter; 27% underwent ET (36% achieved modified Rankin Scale score of 0-2 at 90 days). Median actual transfer time was 132 minutes (interquartile range, 103-165), compared with median ideal transfer time at 102 minutes (interquartile range, 96-123). Longer transfer time was associated with decreased likelihood of undergoing ET (odds ratio, 0.990; P=0.003). Nocturnal transfer (18:00 to 06:00 hours) was associated with significantly longer delay (β=20.5; P<0.0005), whereas intravenous tissue-type plasminogen activator (tPA) delivery at spoke hospital was not. The median delay for nocturnal transfer was 31 minutes (interquartile range, 11-51), compared with daytime at 14 minutes (interquartile range, -9 to 36). CONCLUSIONS Within a large telestroke network, there was an association between longer transfer time and decreased likelihood of undergoing ET. Nocturnal transfers were associated with a substantial delay relative to daytime transfers. In contrast, delivery of tPA was not associated with delays, underscoring the impact of effective protocols at spoke hospitals. More efficient transfer may enable higher ET treatment rates. Metrics and protocols for transfer, especially at night, may improve transfer times.

Abstract
Neurological disorders are the leading cause of global disability. However, for most people around the world, current neurological care is poor. In low-income countries, most individuals lack access to proper neurological care, and in high-income countries, distance and disability limit access. With the global proliferation of smartphones, teleneurology - the use of technology to provide neurological care and education remotely - has the potential to improve and increase access to care for billions of people. Telestroke has already fulfilled this promise, but teleneurology applications for chronic conditions are still in their infancy. Similarly, few studies have explored the capabilities of mobile technologies such as smartphones and wearable sensors, which can guide care by providing objective, frequent, real-world assessments of patients. In low-income settings, teleneurology can increase the capacity of local care systems through professional development, diagnostic support and consultative services. In high-income settings, teleneurology is likely to promote the expansion and migration of neurological care away from institutions, incorporate systems of asynchronous communication (such as e-mail), integrate clinicians with diverse skill sets and reach new populations. Inertia, outdated policies and social barriers - especially the digital divide - will slow this progress at considerable cost. However, a future increasingly will be possible in which neurological care can be accessed by anyone, anywhere. Here, we examine the emerging evidence regarding the benefits of teleneurology for chronic conditions, its role and risks in low-income countries and the promise of mobile technologies to measure disease status and deliver care. We conclude by discussing the future trends, barriers and timing for the adoption of teleneurology.

Abstract
BACKGROUND AND PURPOSE Prehospital stroke scales may help identify patients likely to have large-vessel occlusion to facilitate rapid triage to thrombectomy-capable stroke centers. Scale misclassification may result in inaccurate decisions and possible harm. Pre-existing leukoaraiosis has been shown to attenuate the association between deficit type and stroke severity. We sought to determine whether leukoaraiosis affects the predictive ability of 5 commonly used large-vessel occlusion scales. MATERIALS AND METHODS We retrospectively analyzed 274 consecutive patients with stroke with available brain MR imaging and vessel imaging. We used the following large-vessel occlusion scales: the 3-Item Stroke Scale; Field Assessment Stroke Triage for Emergency Destination; Rapid Arterial Occlusion Evaluation; Vision, Aphasia, Neglect score; and Cincinnati Prehospital Stroke Severity Scale. For diagnostic scale accuracy, we assessed sensitivity, specificity, positive predictive value, negative predictive value, and κ. Multivariable logistic regression was used to determine the predictive ability of the scales after adjustment for leukoaraiosis and potential confounders. RESULTS In unadjusted analyses, all scales predicted the presence of large-vessel occlusion (n = 46, P < .01 each), though diagnostic accuracy was attenuated among patients with moderate-to-severe leukoaraiosis. After adjustment, the Field Assessment Stroke Triage for Emergency Destination (OR = 3.2; 95% CI, 1.1-9.5; P = .033) and Rapid Arterial Occlusion Evaluation (OR = 3.7; 95% CI, 1.3-10.8; P = .015), but not the 3-Item Stroke Scale (OR = 5.4; 95% CI, 0.86-33.9; P = .073), Vision, Aphasia, Neglect score (OR = 2.5; 95% CI, 0.8-7.2), and Cincinnati Prehospital Stroke Severity Scale (OR = 2.8; 95% CI, 1.0-8.0), predicted large-vessel occlusion. CONCLUSIONS The diagnostic accuracy of the tested large-vessel occlusion scales was attenuated in the presence of moderate-to-severe leukoaraiosis. This information that may aid the design of future studies that require large-vessel occlusion scale screening of patients who are likely to have concomitant leukoaraiosis.
