The role of telemedicine in acute stroke treatment in times of pandemic

Cerebrovascular Disease in COVID-19

Not in the history of transmissible illnesses has there been an infection as strongly associated with acute cerebrovascular disease as the novel human coronavirus SARS-CoV-2. While the risk of stroke has known associations with other viral infections, such as influenza and human immunodeficiency virus, the risk of ischemic and hemorrhagic stroke related to SARS-CoV-2 is unprecedented. Furthermore, the coronavirus disease 2019 (COVID-19) pandemic has so profoundly impacted psychosocial behaviors and modern medical care that we have witnessed shifts in epidemiology and have adapted our treatment practices to reduce transmission, address delayed diagnoses, and mitigate gaps in healthcare. In this narrative review, we summarize the history and impact of the COVID-19 pandemic on cerebrovascular disease, and lessons learned regarding the management of patients as we endure this period of human history.

Stroke profile and care during the COVID-19 pandemic: What changed and what did not? A prospective cohort from Joinville, Brazil

Introduction

The COVID-19 pandemic has wrought negative consequences concerning quality of care for stroke patients since its onset. Prospective population-based data about stroke care in the pandemic are limited. This study aims to investigate the impact of COVID-19 pandemic on stroke profile and care in Joinville, Brazil.

Methods

A prospective population-based cohort enrolled the first-ever cerebrovascular events in Joinville, Brazil, and a comparative analyzes was conducted between the first 12 months following COVID-19 restrictions (starting March 2020) and the 12 months just before. Patients with transient ischemic attack (TIA) or stroke had their profiles, incidences, subtypes, severity, access to reperfusion therapy, in-hospital stay, complementary investigation, and mortality compared.

Results

The profiles of TIA/stroke patients in both periods were similar, with no differences in gender, age, severity, or comorbidities. There was a reduction in incidence of TIA (32.8%; p = 0.003). In both periods, intravenous thrombolysis (IV) and mechanical thrombectomy (MT) rates and intervals from door to IV/MT were similar. Patients with cardioembolic stroke and atrial fibrillation had their in-hospital stay abbreviated. The etiologic investigation was similar before and during the pandemic, but there were increases in cranial tomographies (p = 0.02), transthoracic echocardiograms (p = 0.001), chest X-rays (p < 0.001) and transcranial Doppler ultrasounds (p < 0.001). The number of cranial magnetic resonance imaging decreased in the pandemic. In-hospital mortality did not change.

Discussion

The COVID-19 pandemic is associated with a reduction in TIA, without any influence on stroke profile, the quality of stroke care, in-hospital investigation or mortality. Our findings show an effective response by the local stroke care system and offer convincing evidence that interdisciplinary efforts are the ideal approach to avoiding the COVID-19 pandemic's negative effects, even with scarce resources.

Background

As an emerging technology, virtual reality (VR) has been broadly applied in the medical field, especially in neurorehabilitation. The growing application of VR therapy promotes an increasing amount of clinical studies. In this paper, we present a bibliometric analysis of the existing studies to reveal the current research hotspots and guide future research directions.

Methods

Articles and reviews on the related topic were retrieved from the Science Citation Index Expanded of Web of Science Core Collection database. VOSviewer and Citespace software were applied to systematically analyze information about publications, countries, institutions, authors, journals, citations, and keywords from the included studies.

Results

A total of 1,556 papers published between 1995 and 2021 were identified. The annual number of papers increased gradually over the past three decades, with a peak publication year in 2021 (n = 276). Countries and institutions from North America and Western European were playing leading roles in publications and total citations. Current hotspots were focused on the effectiveness of VR therapy in cognitive and upper limb motor rehabilitation. The clusters of keywords contained the four targeted neurological diseases of VR, while the burst keywords represented that the latest studies were directed toward more defined types of VR therapy and greater study design.

Conclusions

Our study offers information regarding to the current hotspots and emerging trends in the VR for rehabilitation field. It could guide future research and application of VR therapy in neurorehabilitation.

Telemedicine During and Post-COVID 19: The Insights of Neurosurgery Patients and Physicians

Objective

COVID-19 has caused a massive surge in telemedicine utilization as patients and physicians tried to minimize in-person contact to avoid the spread and impact of the pandemic.

This study aims to expand on the knowledge of telemedicine during and beyond the COVID-19 era as it pertains to its use, efficacy, and patient and provider satisfaction through surveys.

Methods

This is a retrospective study involving 93 patients and 33 Neurosurgery physicians who anonymously participated in the survey about their experience with telemedicine visits.

Results

Most respondents indicated extreme satisfaction with their telemedicine encounters during the pandemic (77%). As for how comfortable physicians are in providing a diagnosis via telemedicine compared to clinic visits, 7 (21.9%) physicians felt extremely comfortable, 13 (40.6%) felt somewhat comfortable, 2 (6.4%) were neutral, 9 (28.1%) felt somewhat uncomfortable and 1 (3.1%) felt extremely uncomfortable. Physical examination was the main tool that telemedicine didn’t provide (n = 21, 100%).

Conclusion

Telemedicine has become a major force in the health care system under the circumstances the world is witnessing. Physicians and patients have displayed high levels of satisfaction with telemedicine which could be pivotal to improving healthcare access to underprivileged areas beyond the pandemic.

Pathomechanisms and Treatment Implications for Stroke in COVID-19: A Review of the Literature

Stroke in patients with COVID-19 has received increasing attention throughout the global COVID-19 pandemic, perhaps due to the substantial disability and mortality that can result when the two conditions co-occur. We reviewed the existing literature and found that the proposed pathomechanism underlying COVID-19-associated ischemic stroke is broadly divided into the following three categories: vasculitis, endothelialitis, and endothelial dysfunction; hypercoagulable state; and cardioembolism secondary to cardiac dysfunction. There has been substantial debate as to whether there is a causal link between stroke and COVID-19. However, the distinct phenotype of COVID-19-associated strokes, with multivessel territory infarcts, higher proportion of large vessel occlusions, and cryptogenic stroke mechanism, that emerged in pooled analytic comparisons with non-COVID-19 strokes is compelling. Further, in this article, we review the various treatment approaches that have emerged as they relate to the proposed pathomechanisms. Finally, we briefly cover the logistical challenges, such as delays in treatment, faced by providers and health systems; the innovative approaches utilized, including the role of tele-stroke; and the future directions in COVID-19-associated stroke research and healthcare delivery.

Lessons learned in stroke care during COVID-19 pandemic and preparing for future pandemics in the MENA+ region: A consensus statement from the MENA+-SINO

Background

COVID-19 pandemic has negatively impacted stroke care services at multiple levels. There was a decline in acute stroke admissions. Fewer interventions have been performed. Increased “door-to-needle times and “door-to-groin puncture” during this pandemic. These factors combined have led to declining in the favoured outcomes of stroke patients' globally. Yet this pandemic permits an opportunity for higher preparedness for future pandemics.

Objectives and methods

This paper aims to shed light on the main lessons learned in the field of stroke care during the first wave of COVID-19 pandemic. Here we are presenting proposals and initiatives for better preparedness in future similar emergencies. These proposals are based primarily on literature review of COVID-19 publications, as well as the first-hand experience gained during the first wave at the regional level. In addition to the consensus and collective ride of stroke experts in the Middle East North Africa Stroke and Interventional Neurotherapies Organization (MENA+-SINO) and interaction and collaboration with international stroke specialists from the Stroke World Organization (WSO), European Stroke Organization (ESO) and stroke and COVID-19 papers authors.

Conclusion

Stroke care is very complex, particularly in the initial hours after onset of symptoms. A successful outcome requires very close collaboration between clinical personnel from multiple specialties. Preparedness for future pandemics requires the improvement of care plans that allow for rapid assessment of stroke patients and ensuring that regular ‘mock exercises’ familiarize quintessential services that care for the stroke patients.

Role of imaging in early diagnosis of acute ischemic stroke: a literature review

Stroke is a serious health condition that is responsible for more than 5% of total deaths. Near 20% of patients experiencing stroke die every year, resulting in the stroke being at the top of the list of preventable causes of death. Once an acute stroke is suspected, a golden hour of less than an hour is available to prevent the undesirable consequences. Since neuroimaging is mandatory in the diagnosis of stroke, the proper use of neuroimaging could help saving time and planning the right treatment for the patient. Some of the available imaging methods help us with rapid results, while others benefit us from a more accurate diagnosis. Hereby, we aim to provide a clinical review of the advantages and disadvantages of different available neuroimaging methods in approaching acute stroke to help clinicians choose the best method according to the settings.

Implementation and use of mHealth home telemonitoring in adults with acute COVID-19 infection: a scoping review protocol

INTRODUCTION

mHealth refers to digital technologies that, via smartphones, mobile apps and specialised digital sensors, yield real-time assessments of patient's health status. In the context of the COVID-19 pandemic, these technologies enable remote patient monitoring, with the benefit of timely recognition of disease progression to convalescence, deterioration or postacute sequelae. This should enable appropriate medical interventions and facilitate recovery. Various barriers, both at patient and technology levels, have been reported, hindering implementation and use of mHealth telemonitoring. As systematised and synthesised evidence in this area is lacking, we developed this protocol for a scoping review on mHealth home telemonitoring of acute COVID-19.

METHODS AND ANALYSIS

We compiled a search strategy following the PICO (Population, Intervention, Comparator, Outcome) and PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendation for Scoping Reviews) guidelines. MEDLINE, Embase and Web of Science will be searched from 1 March 2020 to 31 August 2021. Following the title and abstract screening, we will identify, systematise and synthesise the available knowledge. Based on pilot searches, we preview three themes for descriptive evidence synthesis. The first theme relates to implementation and use of mHealth telemonitoring, including reported barriers. The second theme covers the interactions of the telemonitoring team within and between different levels of the healthcare system. The third theme addresses how this telemonitoring warrants the continuity of care, also during disease transition into deterioration or postacute sequelae.

ETHICS AND DISSEMINATION

The studied evidence is in the public domain, therefore, no specific ethics approval is required. Evidence dissemination will be via peer-reviewed publications, conference presentations and reports to the policy makers.

Stroke and neurointervention in the COVID-19 pandemic: a narrative review

Introduction: In this review, we will summarize the impact of the COVID-19 pandemic on neurointerventional care for patients with cerebrovascular disease, with a particular emphasis on epidemiology, neurointerventional processes, and lessons learned from paradigm shifts in endovascular care.Areas covered: Peer-reviewed research is summarized regarding the complications of COVID-19 as related to the pandemic's impact on hospital admissions, imaging capabilities, treatment times, and outcomes of neurointerventional cases.Expert opinion: In the first wave of the COVID-19 pandemic, there was a global decline in neuroimaging, use of intravenous thrombolysis, thrombectomy, and coil embolization for ruptured intracranial aneurysms. An early recommendation to utilize general anesthesia and intubate all patients undergoing intervention to avoid an emergent aerosolizing procedure was found to have worse outcomes. The decline in new stroke and subarachnoid hemorrhage diagnoses may be related to patient and/or family fear of seeking acute medical care. A true shift in stroke epidemiology is also possible. As several vaccines become more readily available and the world rebounds from this pandemic, we hope to transform the neurointerventional experiences discussed in this paper into strategies that may improve care delivery of neurologically ill patients during a global crisis.

Telemedicine during the Coronavirus Disease (COVID-19) Pandemic: A Multiple Sclerosis (MS) Outpatients Service Perspective

Background: During the COVID-19 pandemic, the need for a broader implementation of telemedicine for many diseases has become apparent. Televisits are one type of telemedicine in which clinical visits are conducted remotely using an audio-visual connection with the patient at home. The use of televisits is more established in Stroke care but was also recently formally evaluated for Multiple Sclerosis (MS). This retrospective case series describes patient characteristics and reasons for televisits in persons with MS during the COVID-19 pandemic outbreak in Italy, which was declared in February 2020. Methods: Recruitment occurred in a general hospital based MS clinic during Italy’s lockdown months period (9 March–18 May). Each subject completed at least one televisit. The baseline data included were demographics and MS history; reasons for the remote house calls were analyzed focusing on COVID-19 related needs. Results: Forty-six participants completed at least one study visit. The patients enrolled were more often females suffering from Relapsing Remitting Multiple Sclerosis (RRMS). Half of the patients had an intermediate level of education and lived within a 60 min drive from the clinic. These patients predominately had a short disease duration and were mostly involved in oral treatment. The main reasons for the call were drug use and counseling on social distancing. In 5 cases, COVID-19 infection was reported. Conclusions: Televisits during the COVID-19 outbreak demonstrated their utility as a care delivery method for MS. Hence, it is vital to facilitate the implementation of this technology in common practice to both face infectious threats and increase accessibility of the health care system.
