Stroke Telemedicine for Arizona Rural Residents, the Legacy Telestroke Study.

Background: Efficacy of telemedicine for stroke was first established by the Stroke Team Remote Evaluation Using a Digital Observation Camera (STRokE DOC) trials in California and Arizona. Following these randomized controlled trials, the Stroke Telemedicine for Arizona Rural Residents (STARR) network was the first telestroke network to be established in Arizona. It consisted of a 7 spoke 1 hub telestroke system, and it was designed to serve rural, remote, or neurologically underserved communities. Objective: The objective of STARR was to establish a multicenter state-wide telestroke research network to determine the feasibility of prospective collection, recording, and regularly analysis of telestroke patient consultations and care data for the purposes of establishing quality measures, improvement, and benchmarking against other national and international telestroke programs. Methods: The STARR trial was open to enrollment for 29 months from 2008 to 2011. Mayo Clinic Hospital, Phoenix, Arizona served as the hub primary stroke center and its vascular neurologists provided emergency telestroke consultations to seven participating rural, remote, or underserved spoke community hospitals in Arizona. Eligibility criteria for activation of a telestroke alert and study enrollment were established. Consecutive patients exhibiting symptoms and signs of acute stroke within a 12 h window were enrolled, assessed, and treated by telemedicine. The state government sponsor, Arizona Department of Health Services' research grant covered the cost of acquisition, maintenance, and service of the selected telemedicine equipment as well as the professional telestroke services provided. The study deployed multiple telemedicine video cart systems, picture archive and communications systems software, and call management solutions. The STARR protocol was reviewed and approved by Mayo Clinic IRB, which served as the central IRB of record for all the participating hospitals, and the trial was registered at ClinicalTrials.gov. Results: The telestroke hotline was activated 537 times, and ultimately 443 subjects met criteria and consented to participate. The STARR successfully established a multicenter state-wide telestroke research network. The STARR developed a feasible and pragmatic approach to the prospective collection, storage, and analysis of telestroke patient consultations and care data for the purposes of establishing quality measures and tracking improvement. STARR benchmarked well against other national and international telestroke programs. STARR helped set the foundation for multiple regional and state telestroke networks and ultimately evolved into a national telestroke network. Conclusions: Multiple small and rurally located community hospitals and health systems can successfully collaborate with a more centrally located larger hospital center through telemedicine technologies to develop a coordinated approach to the assessment, diagnosis, and emergency treatment of patients manifesting symptoms and signs of an acute stroke syndrome. This model may serve well the needs of patients presenting with other time-sensitive medical emergencies.Clinical Trial Registration number: NCT00829361.

A Scalable Framework for Telehealth: The Mayo Clinic Center for Connected Care Response to the COVID-19 Pandemic.

Background: The Mayo Clinic Center for Connected Care has an established organizational framework for telehealth care delivery. It provides patients, consumers, care teams, and referring providers access to clinical knowledge through technologies and integrated practice models. Central to the framework are teams that support product management and operational functions. They work together across the asynchronous, synchronous video telemedicine, remote patient monitoring (RPM), and mobile core service lines. Methods: The organizational framework of the Center for Connected Care and Mayo Clinic telehealth response to the COVID-19 pandemic is described. Barriers to telehealth delivery that were addressed by the public health emergency are also reported. This report was deemed exempt from full review by the Mayo Clinic IRB. Results: After declaration of the COVID-19 pandemic, there was rapid growth in established telehealth offerings, including patient online services account creation, secure messaging, inpatient eConsults, express care online utilization, and video visits to home. Census for the RPM program for patients with chronic conditions remained stable; however, its framework was rapidly adapted to develop and implement a COVID-19 RPM service. In addition to this, other new telehealth and virtual care services were created to support the unique needs of patients with COVID-19 symptoms or disease and the health care workforce, including a digital COVID-19 self-assessment tool and video telemedicine solutions for ambulances, emergency departments, intensive care units, and designated medical-surgical units. Conclusion: Rapid growth, adoption, and sustainability of telehealth services through the COVID-19 pandemic were made possible by a scalable framework for telehealth and alignment of regulatory and reimbursement models.

Teleneurosonology: a novel application of transcranial and carotid ultrasound.

BACKGROUND: To demonstrate the technical feasibility of interfacing transcranial Doppler (TCD) and carotid "duplex" ultrasonography (CUS) peripherals with telemedicine end points to provide real-time spectral waveform and duplex imaging data for remote review and interpretation. METHODS: We performed remote TCD and CUS examinations on a healthy, volunteer employee from our institution without known cerebrovascular disease. The telemedicine end point was stationed in our institution's hospital where the neurosonology examinations took place and the control station was in a dedicated telemedicine room in a separate building. The examinations were performed by a postgraduate level neurohospitalist trainee (M.N.R.) and interpreted by an attending vascular neurologist, both with experience in the performance and interpretation of TCD and CUS. RESULTS: Spectral waveform and duplex ultrasound data were successfully transmitted from TCD and CUS instruments through a telemedicine end point to a remote reviewer at a control station. Image quality was preserved in all cases, and technical failures were not encountered. CONCLUSIONS: This proof-of-concept study demonstrates the technical feasibility of interfacing TCD and CUS peripherals with a telemedicine end point to provide real-time spectral waveform and duplex imaging data for remote review and interpretation. Medical diagnostic and telemedicine devices should be equipped with interfaces that allow simple transmission of high-quality audio and video information from the medical devices to the telemedicine technology. Further study is encouraged to determine the clinical impact of teleneurosonology.

Systematic review of teleneurology: neurohospitalist neurology.

The use of 2-way audiovisual telemedicine technology for the delivery of acute stroke care is well established in the literature and is a growing practice. The use of such technology for neurologic consultation outside the cerebrovascular specialty has been reported to a variable extent across most disciplines within the field of neurology, including that of the neurohospitalist medicine. A systematic review of these reports is lacking. Hence, the main purpose of this study was to conduct a systematic review of the literature on teleneurologic consultation in hospital neurology. The databases Ovid MEDLINE, EMBASE, PsychINFO, CINAHL, and Cochrane were used as data sources and were searched with key words "teleneurology" and its numerous synonyms and cognates. These key words were cross-referenced with subspecialties of neurology. The studies were included for further review only if the title or the abstract indicated that the study made use of 2-way audiovisual communication to address a neurologic indication. This search yielded 6625 abstracts. By consensus between the 2 investigators, 688 publications met the criteria for inclusion and further review. Four of those citations directly pertained to the inpatient hospital neurologic consultation. Each of the 4 relevant articles was scored with a novel rubric scoring functionality, application, technology, and evaluation phase. A subspecialty category score was calculated by averaging those scores. The use of 2-way audiovisual technology for general neurologic consultation of hospital inpatients, beyond stroke-related care, is promising, but the evidence supporting its routine use is weak. Further studies on reliability, validity, safety, efficacy, and cost-effectiveness are encouraged.

Systematic review of telestroke for post-stroke care and rehabilitation.

Telemedicine for acute stroke care is supported by a literature base. It remains unclear whether or not the use of telemedicine for other phases of stroke care is beneficial. The authors conducted a systematic review of the published literature on telemedicine for the purposes of providing post-stroke care. Studies were included if the title or abstract expressed use of two-way audio/video communication for post-stroke care. From an initial yield of 1,405 potentially eligible hits, two reviewers ultimately identified 24 unique manuscripts to undergo functionality, application, technology, and evaluative (F.A.T.E.) scoring. Each article was classified using a scoring rubric to assess the functionality, application, technology, and evaluative stage. It was found that most post-stroke telemedicine studies evaluated rehabilitation of adults. All primary data manuscripts were small and preliminary in scope and evaluative phase, and median F.A.T.E. score for primary data was 2. The use of telemedicine for post-stroke care is nascent and is primarily focused on post-stroke rehabilitation.

Role of telemedicine in providing tertiary neurological care.

OPINION STATEMENT: Remote consultation via telemedicine for neurologic indications is in the mainstream. This holds most true for cerebrovascular concerns such as acute stroke, but its use has extended into most of the breadth of neurologic subspecialty practice. This is ostensibly a major advance for enhancing access to neurologic specialty care and a path toward better outcomes overall. Currently, there is a lack of randomized controlled trials and health economic analyses to support this conclusion. The continued use and expansion of teleneurologic practice is encouraged, so long as it is accompanied by clinical data tracking and leads to more randomized controlled trials. A solid evidence base should be established for its use such that future trials and monetary investments can be made with a better understanding of what teleneurology has to offer patients and society.

A systematic review of telestroke.

BACKGROUND: The use of 2-way audiovisual (AV) technology for delivery of acute stroke evaluation and management, termed "telestroke," is supported by a rapidly growing literature base. A systematic review that provides a comprehensive, easily digestible overview of telestroke science and practice is lacking. PURPOSE: To conduct a systematic review of the published literature on telemedical consultation for the purposes of providing acute stroke evaluation and management. DATA SOURCES: The Ovid Medline, Embase, PsychINFO, CINAHL, PubMed, and Cochrane databases were searched with numerous keywords relevant to telestroke from January 1996 through July 2012. STUDY SELECTION: Studies were included if the title or abstract expressed use of 2-way AV communication for acute stroke evaluation and management. DATA EXTRACTION: Each article was classified using a novel scoring rubric to assess the level of Functionality, Application, Technology, and Evaluative stage (FATE). DATA ANALYSIS: The search yielded 1405 potentially eligible articles, which were independently reviewed by 2 investigators. There were 344 unique studies that met eligibility criteria and underwent full-text review. Ultimately, 145 unique studies underwent FATE assessment and scoring. RESULTS: Most telestroke studies evaluated functionality in the context of acute stroke assessment of adults in emergency departments. Nearly half of all published articles on telestroke were narrative reviews. After exclusion of these reviews, the median FATE score for telestroke primary data was 4. CONCLUSION: Telestroke technology is now part of mainstream clinical stroke practice in North America and internationally. Telestroke reliability, validity, efficacy, safety, clinical, and cost-effectiveness studies reflect maturity in the field, and new post-implementation studies in the pre-hospital setting present welcome and sophisticated advancements in the field.

Reliability of real-time video smartphone for assessing National Institutes of Health Stroke Scale scores in acute stroke patients.

BACKGROUND AND PURPOSE: Telestroke reduces acute stroke care disparities between urban stroke centers and rural hospitals. Current technologies used to conduct remote patient assessments have high start-up costs, yet they cannot consistently establish quality timely connections. Smartphones can be used for high-quality video teleconferencing. They are inexpensive and ubiquitous among health care providers. We aimed to study the reliability of high-quality video teleconferencing using smartphones for conducting the National Institutes of Health Stroke Scale (NIHSS). METHODS: Two vascular neurologists assessed 100 stroke patients with the NIHSS. The remote vascular neurologist assessed subjects using smartphone videoconferencing with the assistance of a bedside medical aide. The bedside vascular neurologist scored patients contemporaneously. Each vascular neurologist was blinded to the other's NIHSS scores. We tested the inter-method agreement and physician satisfaction with the device. RESULTS: We demonstrated high total NIHSS score correlation between the methods (r=0.949; P<0.001). The mean total NIHSS scores for bedside and remote assessments were 7.93±8.10 and 7.28±7.85, with ranges, of 0 to 35 and 0 to 37, respectively. Eight categories had high agreement: level of consciousness (questions), level of consciousness (commands), visual fields, motor left and right (arm and leg), and best language. Six categories had moderate agreement: level of consciousness (consciousness), best gaze, facial palsy, sensory, dysarthria, and extinction/inattention. Ataxia had poor agreement. There was high physician satisfaction with the smartphone. CONCLUSIONS: Smartphone high-quality video teleconferencing is reliable, easy to use, affordable for telestroke NIHSS administration, and has high physician satisfaction.

Systematic review of teleneurology: methodology.

BACKGROUND: The use of two-way audio-visual technology for delivery of acute stroke is supported by a well established literature base. The use of telemedicine for general neurologic consultation has been reported across most subspecialties within the field, but a comprehensive systematic review of these reports is lacking. PURPOSE: To conduct a systematic review of the published literature on teleneurologic consultation beyond stroke. DATA SOURCES: Databases Ovid MEDLINE, EMBASE, PsychINFO, CINAHL, and Cochrane were searched with keywords, "teleneurology," and numerous synonyms and cross-referenced with neurology subspecialties. The search yielded 6,615 potentially eligible hits, which were independently reviewed by two investigators. Ultimately 375 unique studies met eligibility criteria and were included in the review. STUDY SELECTION: Studies were included if the title or abstract expressed use of two-way AV communication for a clinical neurologic indication other than stroke. DATA EXTRACTION: Each article was classified using a novel scoring rubric to assess the level of functionality, application, technology, and evaluative stage. DATA ANALYSIS: Articles were hierarchized within a subspecialty category. Overall subspecialty scores were assigned based on aggregate of scores across papers in each category. CONCLUSION: Use of telemedicine for general and most subspecialty neurologic consultation, beyond stroke, appears very promising but the clinical science is nascent.

Teleconcussion: an innovative approach to screening, diagnosis, and management of mild traumatic brain injury.

Concussion awareness and management in sports have gained a great deal of attention in light of research illustrating the potentially devastating consequences of repeated traumatic brain injuries. In order to address this public health crisis, numerous states have passed legislation that mandates medical clearance before being eligible to return to play of concussed athletes by a qualified healthcare provider. As the number of qualified healthcare providers with expertise in the diagnosis and management of concussions remains very small, patient safety and the ability to fulfill these legislative return-to-play requirements present unique problems to rural communities without easy access to subspecialty care. Telemedicine is a possible means by which to address the needs of the rural student-athlete.

Smartphone teleradiology application is successfully incorporated into a telestroke network environment.

BACKGROUND AND PURPOSE: ResolutionMD mobile application runs on a Smartphone and affords vascular neurologists access to radiological images of patients with stroke from remote sites in the context of a telemedicine evaluation. Although reliability studies using this technology have been conducted in a controlled environment, this study is the first to incorporate it into a real-world hub and spoke telestroke network. The study objective was to assess the level of agreement of brain CT scan interpretation in a telestroke network between hub vascular neurologists using ResolutionMD, spoke radiologists using a Picture Archiving and Communications System, and independent adjudicators. METHODS: Fifty-three patients with stroke at the spoke hospital consented to receive a telemedicine consultation and participate in a registry. Each CT was evaluated by a hub vascular neurologist, a spoke radiologist, and by blinded telestroke adjudicators, and agreement over clinically important radiological features was calculated. RESULTS: Agreement (κ and 95% CI) between hub vascular neurologists using ResolutionMD and (1) the spoke radiologist; and (2) independent adjudicators, respectively, were: identification of intracranial hemorrhage 1.0 (0.92-1.0), 1.0 (0.93-1.0), neoplasm 1.0 (0.92-1.0), 1.0 (0.93-1.0), any radiological contraindication to thrombolysis 1.0 (0.92-1.0), 0.85 (0.65-1.0), early ischemic changes 0.62 (0.28-0.96), 0.58 (0.30-0.86), and hyperdense artery sign 0.40 (0.01-0.80), 0.44 (0.06-0.81). CONCLUSIONS: CT head interpretations of telestroke network patients by vascular neurologists using ResolutionMD on Smartphones were in excellent agreement with interpretations by spoke radiologists using a Picture Archiving and Communications System and those of independent telestroke adjudicators using a desktop viewer.
