A narrative review of telemedicine and its adoption across specialties.

Background and Objective: Telemedicine and video consultation are crucial advancements in healthcare, allowing remote delivery of care. Telemedicine, encompassing various technologies like wearable devices, mobile health, and telemedicine, plays a significant role in managing illnesses and promoting wellness. The corona virus disease 2019 (COVID-19) pandemic accelerated the adoption of telemedicine, ensuring convenient access to medical services while maintaining physical distance. Legislation has supported its integration into clinical practice and addressed compensation issues. However, ensuring clinical appropriateness and sustainability of telemedicine post-expansion has gained attention. We south to identify the most friendly and resistant specialties to telemedicine and to understand areas of interest within those specialties to grasp potential barriers to its use. Methods: We aimed to identify articles that incorporated telemedicine in any medical or surgical specialty and determine the adoption rate and intent of this new form of care. Additionally, a secondary search within these databases was conducted to analyze the advantages, disadvantages, and implementation of telemedicine in the healthcare system. Non-English articles and those without full text were excluded. The study selection and data collection process involved using search terms such as "medicine", "surgery", "specialties", "telemedicine", and "telemedicine". Key Content and Findings: Telemedicine adoption varies among specialties. The pandemic led to increased usage, with telemedicine consultations comprising 30.1% of all visits, but specialties like mental health, gastroenterology, and endocrinology showed higher rates of adoption compared to optometry, physical therapy, and orthopedic surgery. Conclusions: The data shows that telemedicine uptake varies by specialty and condition due to the need for physical exams. In-person visits still dominate new patient visits despite increased telemedicine use. Telemedicine cannot fully replace in-person care but has increased visit volume and is secure. The adoption of telemedicine is higher in medical practices than in surgical practices, with neurosurgery and urology leading. Further research is needed to assess telemedicine's suitability and effectiveness in different specialties and conditions.

Thrombolytic Therapy for Central Retinal Artery Occlusion in an Academic Multi-Site Stroke Centre.

Central retinal artery occlusion (CRAO) is a subtype of acute ischaemic stroke leading to severe visual loss. A recent American Heart Association scientific statement proposed time-windows for thrombolysis in CRAO similar to acute ischaemic cerebral strokes. We aimed to review our academic multi-site stroke centre experience with intravenous (IVT) and intra-arterial thrombolysis (IAT) in CRAO between 1997 and 2022. Demographic, clinical characteristics, thrombolysis timeline, concurrent therapies, complications, and 3-month follow-up visual acuity (VA) were collected. The thrombolysed cohort follow-up VA was compared with an age, gender and baseline VA matched cohort of CRAO patients that received conservative therapies. Thrombolytic therapy was administered to 3.55% (n = 20) of CRAO admissions; 13 IVT (mean age 68, 61.5% male, 12 alteplase and 1 tenecteplase, all embolic aetiology, 1 CRAO mimic) and 7 IAT (mean age 55, 85.7% male, 3 post-operative and 3 embolic). Additional conservative CRAO-targeting therapies was received by 60%. The median time from onset of visual loss to IVT was 158 minutes (range 67-260). Improvement by at least two Snellen lines was achieved by 25% with 12.5% improving to 20/100 or better. Intracranial haemorrhage post IVT occurred in 1/13 (7.6%). The median time from onset of visual loss to IAT was 335 minutes. Improvement by at least two Snellen lines was achieved by 42%. No difference in 3-month VA was noted between patients that received thrombolysis, either alone (n = 8) or combined with other therapies, and those that received conservative therapies. Our results suggest that the management of acute CRAO remains heterogeneous. The lack of obvious benefit of thrombolysis in our small series supports the need for randomizsd clinical trials comparing thrombolysis to placebo to guide hyperacute CRAO management.

Does Initiation of Prophylactic Antiseizure Medication Improve Neurological Outcomes in Patients With Acute Intracerebral Hemorrhage?: A Critically Appraised Topic.

OBJECTIVE: The objective of this study was to critically assess current evidence regarding the role of prophylactic antiseizure medication in patients presenting with acute intracerebral hemorrhage (ICH). METHODS: The objective was addressed through the development of a structured critically appraised topic. This included a clinical scenario with a clinical question, literature search strategy, critical appraisal, results, evidence summary, commentary, and bottom-line conclusions. Participants included resident neurologists, a medical librarian, and content experts in the fields of epilepsy, stroke neurology, neurohospitalist medicine, and neurocritical care. RESULTS: A randomized clinical trial was selected for critical appraisal. The trial assessed whether prophylactic levetiracetam (LEV) use reduced the risk of acute seizures in patients with ICH, as defined by clinical or electrographic seizure, captured by continuous electroencephalogram 72 hours after enrollment. A total of 42 patients were included in the final analysis (19 in the LEV group and 23 in the placebo group). There was a significantly higher occurrence of seizures in the placebo versus LEV group (LEV 16% vs placebo 43%, P = 0.043). There were no differences in functional outcomes between the groups at 3, 6, or 12 months (P > 0.1). CONCLUSIONS: The role of prophylactic treatment with antiseizure medication in ICH remains unclear.

Prehospital stroke scales outperform National Institutes of Health Stroke Scale in predicting large vessel occlusion in a large academic telestroke network.

INTRODUCTION: Prehospital telestroke evaluations may improve stroke triage compared to paramedic-applied large vessel occlusion scales, but ambulance-based video National Institutes of Health Stroke Scale assessments are challenging. The accuracy of telestroke-administered large vessel occlusion scales has not been investigated, so we sought to evaluate this further. METHODS: This retrospective study included all in-hospital telestroke encounters in a large academic telestroke network from 2019 to 2020. We retrospectively calculated seven large vessel occlusion scales using the in-hospital telestroke National Institutes of Health Stroke Scale (Rapid Arterial oCclusion Evaluation, Cincinnati Stroke Triage Assessment Tool, Field Assessment Stroke Triage for Emergency Destination, 3-Item Stroke Scale, Prehospital Acute Stroke Severity, Vision-Aphasia-Neglect, and Gaze-Face-Arm-Speech-Time). Diagnostic performance was assessed via sensitivity, specificity, negative predictive value, positive predictive value, positive likelihood ratio, negative likelihood ratio, and accuracy using established scale thresholds. These results were compared to the National Institutes of Health Stroke Scale at thresholds of 6, 8, and 10. The area under curve was calculated using c-statistics by treating scales as continuous variables. RESULTS: A total of 625 patients were included; 111 (17.8%) patients had an anterior large vessel occlusion, 118 (18.9%) patients had any large vessel occlusion, and 182 (29.1%) patients had stroke mimic diagnosis. The mean age (SD) was 67.9 (15.9), 48.3% were female, and 93.4% were white. The Mean National Institutes of Health Stroke Scale (SD) was 14.9 (8.4) for patients with anterior large vessel occlusion, 4.7 (5.0) for patients with non-large vessel occlusion ischemic stroke, and 4.4 (5.8) for stroke mimic (p < 0.001). Compared to the National Institutes of Health Stroke Scale, Field Assessment Stroke Triage for Emergency Destination, and Rapid Arterial oCclusion Evaluation scales demonstrated higher accuracy and area under curve for large vessel occlusion detection. DISCUSSION: Both the Field Assessment Stroke Triage for Emergency Destination and Rapid Arterial oCclusion Evaluation scales outperformed the National Institutes of Health Stroke Scale for large vessel occlusion detection in patients evaluated by in-hospital telestroke. These scales may be valid alternatives to the National Institutes of Health Stroke Scale examination in this setting.

Artificial Intelligence Models in Health Information Exchange: A Systematic Review of Clinical Implications.

Electronic health record (EHR) systems collate patient data, and the integration and standardization of documents through Health Information Exchange (HIE) play a pivotal role in refining patient management. Although the clinical implications of AI in EHR systems have been extensively analyzed, its application in HIE as a crucial source of patient data is less explored. Addressing this gap, our systematic review delves into utilizing AI models in HIE, gauging their predictive prowess and potential limitations. Employing databases such as Scopus, CINAHL, Google Scholar, PubMed/Medline, and Web of Science and adhering to the PRISMA guidelines, we unearthed 1021 publications. Of these, 11 were shortlisted for the final analysis. A noticeable preference for machine learning models in prognosticating clinical results, notably in oncology and cardiac failures, was evident. The metrics displayed AUC values ranging between 61% and 99.91%. Sensitivity metrics spanned from 12% to 96.50%, specificity from 76.30% to 98.80%, positive predictive values varied from 83.70% to 94.10%, and negative predictive values between 94.10% and 99.10%. Despite variations in specific metrics, AI models drawing on HIE data unfailingly showcased commendable predictive proficiency in clinical verdicts, emphasizing the transformative potential of melding AI with HIE. However, variations in sensitivity highlight underlying challenges. As healthcare's path becomes more enmeshed with AI, a well-rounded, enlightened approach is pivotal to guarantee the delivery of trustworthy and effective AI-augmented healthcare solutions.

Payment and Coverage Parity for Virtual Care and In-Person Care: How Do We Get There?

Background: A steep increase in the use of delivery of virtual care occurred during the COVID-19 public health emergency (PHE) because of easing up of payment and coverage restrictions. With the end of PHE, there is uncertainty regarding continued coverage and payment parity for the virtual care services. Methods: On November 8, 2022, The Mass General Brigham held the Third Annual Virtual Care Symposium: Demystifying Clinical Appropriateness in Virtual Care and What's Ahead for Pay Parity. Results: In one of the panels, experts from Mayo Clinic led by Dr. Bart Demaerschalk discussed key issues related to "Payment and Coverage Parity for Virtual Care and In-Person Care: How Do We Get There?" The discussions centered around current policies around payment and coverage parity for virtual care, including state licensure laws for virtual care delivery and the current evidence base regarding outcomes, costs, and resource utilization associated with virtual care. The panel discussion ended with highlighting next steps targeting policymakers, payers, and industry groups to help strengthen the case for parity. Conclusions: To ensure the continued viability of virtual care delivery, legislators and insurers must address the coverage and payment parity between telehealth and in-person visits. This will require a renewed focus on research on clinical appropriateness, parity, equity and access, and economics of virtual care.

Evaluating the feasibility of a multicenter teleneonatology clinical effectiveness trial.

BACKGROUND: Our research consortium is preparing for a prospective multicenter trial evaluating the impact of teleneonatology on the health outcomes of at-risk neonates born in community hospitals. We completed a 6-month pilot study to determine the feasibility of the trial protocol. METHODS: Four neonatal intensive care units ("hubs") and four community hospitals ("spokes") participated in the pilot-forming four hub-spoke dyads. Two hub-spoke dyads implemented synchronous, audio-video telemedicine consultations with a neonatologist ("teleneonatology"). The primary outcome was a composite feasibility score that included one point for each of the following: site retention, on-time screening log completion, no eligibility errors, on-time data submission, and sponsor site-dyad meeting attendance (score range 0-5). RESULTS: For the 20 hub-spoke dyad months, the mean (range) composite feasibility score was 4.6 (4, 5). All sites were retained during the pilot. Ninety percent (18/20) of screening logs were completed on time. The eligibility error rate was 0.2% (3/1809). On-time data submission rate was 88.4% (84/95 case report forms). Eighty-five percent (17/20) of sponsor site-dyad meetings were attended by both hub and spoke site staff. CONCLUSIONS: A multicenter teleneonatology clinical effectiveness trial is feasible. Learnings from the pilot study may improve the likelihood of success of the main trial. IMPACT: A prospective, multicenter clinical trial evaluating the impact of teleneonatology on the early health outcomes of at-risk neonates born in community hospitals is feasible. A multidimensional composite feasibility score, which includes processes and procedures fundamental to completing a clinical trial, is useful for quantitatively measuring pilot study success. A pilot study allows the investigative team to test trial methods and materials to identify what works well or requires modification. Learnings from a pilot study may improve the quality and efficiency of the main effectiveness trial.

Telemedicine for Acute Monocular Visual Loss: A Retrospective Large Telestroke Network Experience.

Introduction: Central retinal artery occlusion (CRAO) is an under-recognized stroke subtype that may benefit from hyperacute reperfusion therapies. We aimed to evaluate the ability of telestroke activations to provide CRAO diagnosis and thrombolysis. Methods: This retrospective observational study investigates all encounters conducted for acute visual loss between 2010 and 2021 in our multicentric Mayo Clinic Telestroke Network. Demographics, time from visual loss to telestroke evaluation, ocular examination, diagnostic, and therapeutic recommendations were collected for CRAO subjects. Results: Out of 9,511, 49 encounters (0.51%) were conducted for an acute ocular complaint. Five patients had possible CRAO, and 4 presented within 4.5 h from symptom onset (range 1.5-5 h). None received thrombolytic therapy. All telestroke physicians recommended ophthalmology consultation. Conclusion: Current telestroke assessment of acute visual loss is suboptimal and patients eligible for acute reperfusion therapies may not be offered treatment. Teleophthalmologic evaluations and advanced ophthalmic diagnostic tools should complement telestroke systems.

Quality Frameworks for Virtual Care: Expert Panel Recommendations.

Given the significant advance of virtual care in the past year and half, it seems timely to focus on quality frameworks and how they have evolved collaboratively across health care organizations. Massachusetts General Hospital's (MGH) Center for TeleHealth and Mass General Brigham's (MGB) Virtual Care Program are committed to hosting annual symposia on key topics related to virtual care. Subject matter experts across the country, health care organizations, and academic medical centers are invited to participate. The inaugural MGH/MGB Virtual Care Symposium, which focused on rethinking curriculum, competency, and culture in the virtual care era, was held on September 2, 2020. The second MGH/MGB Virtual Care Symposium was held on November 2, 2021, and focused on virtual care quality frameworks. Resultant topics were (1) guiding principles necessary for the future of virtual care measurement; (2) best practices deployed to measure quality of virtual care and how they compare and align with in-person frameworks; (3) evolution of quality frameworks over time; (4) how increased adoption of virtual care has impacted patient access and experience and how it has been measured; (5) the pitfalls and barriers which have been encountered by organizations in developing virtual care quality frameworks; and (6) examples of how quality frameworks have been applied in various use cases. Common elements of a quality framework for virtual care programs among symposium participants included improving the patient and provider experience, a focus on achieving health equity, monitoring success rates and uptime of the technical elements of virtual care, financial stewardship, and clinical outcomes. Virtual care represents an evolution in the access to care paradigm that helps keep health care aligned with other modern industries in digital technology and systems adoption. With advances in health care delivery models, it is vitally important that the quality measurement systems be adapted to include virtual care encounters. New methods may be necessary for asynchronous transactions, but synchronous virtual visits and consults can likely be accommodated in traditional quality frameworks with minimal adjustments. Ultimately, quality frameworks for health care will adapt to hybrid in-person and virtual care practices.

Provider Perspectives on the Acceptability, Appropriateness, and Feasibility of Teleneonatology.

OBJECTIVE: We aimed to measure provider perspectives on the acceptability, appropriateness, and feasibility of teleneonatology in neonatal intensive care units (NICUs) and community hospitals. STUDY DESIGN: Providers from five academic tertiary NICUs and 27 community hospitals were surveyed using validated implementation measures to assess the acceptability, appropriateness, and feasibility of teleneonatology. For each of the 12 statements, scale values ranged from 1 to 5 (1 = strongly disagree; 5 = strongly agree), with higher scores indicating greater positive perceptions. Survey results were summarized, and differences across respondents assessed using generalized linear models. RESULTS: The survey response rate was 56% (203/365). Respondents found teleneonatology to be acceptable, appropriate, and feasible. The percent of respondents who agreed with each of the twelve statements ranged from 88.6 to 99.0%, with mean scores of 4.4 to 4.7 and median scores of 4.0 to 5.0. There was no difference in the acceptability, appropriateness, and feasibility of teleneonatology when analyzed by professional role, years of experience in neonatal care, or years of teleneonatology experience. Respondents from Level I well newborn nurseries had greater positive perceptions of teleneonatology than those from Level II special care nurseries. CONCLUSION: Providers in tertiary NICUs and community hospitals perceive teleneonatology to be highly acceptable, appropriate, and feasible for their practices. The wide acceptance by providers of all roles and levels of experience likely demonstrates a broad receptiveness to telemedicine as a tool to deliver neonatal care, particularly in rural communities where specialists are unavailable. KEY POINTS: · Neonatal care providers perceive teleneonatology to be highly acceptable, appropriate, and feasible.. · Perceptions of teleneonatology do not differ based on professional role or years of experience.. · Perceptions of teleneonatology are especially high in smaller hospitals with well newborn nurseries..

Assessment of Clinician Diagnostic Concordance With Video Telemedicine in the Integrated Multispecialty Practice at Mayo Clinic During the Beginning of COVID-19 Pandemic From March to June 2020.

Importance: There was a shift in patient volume from in-person to video telemedicine visits during the COVID-19 pandemic. Objective: To determine the concordance of provisional diagnoses established at a video telemedicine visit with diagnoses established at an in-person visit for patients presenting with a new clinical problem. Design, Setting, and Participants: This is a diagnostic study of patients who underwent a video telemedicine consultation followed by an in-person outpatient visit for the same clinical problem in the same specialty within a 90-day window. The provisional diagnosis made during the video telemedicine visit was compared with the reference standard diagnosis by 2 blinded, independent medical reviewers. A multivariate logistic regression model was used to determine factors significantly related to diagnostic concordance. The study was conducted at a large academic integrated multispecialty health care institution (Mayo Clinic locations in Rochester, Minnesota; Scottsdale and Phoenix, Arizona; and Jacksonville, Florida; and Mayo Clinic Health System locations in Iowa, Wisconsin, and Minnesota) between March 24 and June 24, 2020. Participants included Mayo Clinic patients residing in the US without age restriction. Data analysis was performed from December 2020 to June 2021. Exposures: New clinical problem assessed via video telemedicine visit to home using Zoom Care Anyplace integrated into Epic. Main Outcomes and Measures: Concordance of provisional diagnoses established over video telemedicine visits compared against a reference standard diagnosis. Results: There were 2393 participants in the analysis. The median (IQR) age of patients was 53 (37-64) years; 1381 (57.7%) identified as female, and 1012 (42.3%) identified as male. Overall, the provisional diagnosis established over video telemedicine visit was concordant with the in-person reference standard diagnosis in 2080 of 2393 cases (86.9%; 95% CI, 85.6%-88.3%). Diagnostic concordance by International Statistical Classification of Diseases and Related Health Problems, Tenth Revision chapter ranged from 64.7% (95% CI, 42.0%-87.4%) for diseases of the ear and mastoid process to 96.8% (95% CI, 94.7%-98.8%) for neoplasms. Diagnostic concordance by medical specialty ranged from 77.3% (95% CI, 64.9%-89.7%) for otorhinolaryngology to 96.0% (92.1%-99.8%) for psychiatry. Specialty care was found to be significantly more likely than primary care to result in video telemedicine diagnoses concordant with a subsequent in-person visit (odds ratio, 1.69; 95% CI, 1.24-2.30; P < .001). Conclusions and Relevance: This diagnostic study of video telemedicine visits yielded a high degree of diagnostic concordance compared with in-person visits for most new clinical concerns. Some specific clinical circumstances over video telemedicine were associated with a lower diagnostic concordance, and these patients may benefit from timely in-person follow-up.

Optimizing Door-to-Groin Puncture Time: The Mayo Clinic Experience.

Objectives: To provide a better understanding of methods that can be used to improve patient outcomes by reducing the door-to-groin puncture (DTP) time and present the results of a stroke quality improvement project (QIP) conducted by Mayo Clinic Arizona's stroke center. Methods: We conducted a systematic literature search of Ovid MEDLINE(R), Ovid EMBASE, Scopus, and Web of Science for studies that evaluated DTP time reduction strategies. Those determined eligible for the purpose of this analysis were assessed for quality. The strategies for DTP time reduction were categorized on the basis of modified Target: Stroke Phase III recommendations and analyzed using a meta-analysis. The Mayo Clinic QIP implemented a single-call activation system to reduce DTP times by decreasing the time from neurosurgery notification to case start. Results: Fourteen studies were selected for the analysis, consisting of 2277 patients with acute ischemic stroke secondary to large-vessel occlusions. After intervention, all the studies showed a reduction in the DTP time, with the pooled DTP improvement being the standardized mean difference (1.37; 95% confidence interval, 1.20-1.93; τ2=1.09; P<.001). The Mayo Clinic QIP similarly displayed a DTP time reduction, with the DTP time dropping from 125.1 to 82.5 minutes after strategy implementation. Conclusion: Computed tomography flow modifications produced the largest and most consistent reduction in the DTP time. However, the reduction in the DTP time across all the studies suggests that any systematic protocol aimed at reducing the DTP time can produce a beneficial effect. The relative novelty of mechanical thrombectomy and the consequential lack of research call for future investigation into the efficacy of varying DTP time reduction strategies.

Improving the Telemedicine Evaluation of Patients With Acute Vision Loss: A Call to Eyes.

Acute vision loss related to cerebral or retinal ischemia is a time-sensitive emergency with potential treatment options including IV or intra-arterial thrombolysis and mechanical thrombectomy. However, patients either present in a delayed fashion or present to an emergency department that lacks the subspecialty expertise to recognize and treat these conditions in a timely fashion. Moreover, health care systems in the United States are becoming increasingly reliant on telestroke and teleneurology services for acute neurologic care, making the accurate diagnosis of acute vision loss even more challenging due to critical limitations to the remote video evaluation, including the inability to perform routine ophthalmoscopy. The COVID-19 pandemic has led to a greater reliance on telemedicine services and helped to accelerate the development of novel tools and care pathways to improve remote ophthalmologic evaluation, but these tools have yet to be adapted for use in the remote evaluation of acute vision loss. Permanent vision loss can be disabling for patients, and efforts must be made to increase and improve early diagnosis and management. Herein, the authors outline the importance of improving acute ophthalmologic diagnosis, outline key limitations and barriers to the current video-based teleneurology assessments, highlight opportunities to leverage new tools to enhance the remote assessment of vision loss, and propose new avenues to improve access to emergent ophthalmology subspecialty.

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.

Embolic Stroke in Setting of Iliac Vein Stenosis in an Avid Cyclist.

External iliac vein stenosis related to cycling has rarely been reported as a cause of deep vein thrombosis. Ischemic stroke occurring in this condition due to paradoxical embolism across a preexisting patent foramen ovale (PFO) has yet to be reported. Here we report a case of embolic ischemic strokes in a young, avid cyclist with no prior known vascular risk factors. A thorough cerebrovascular workup revealed a right-to-left shunt on transesophageal echocardiogram that prompted venous thrombosis evaluation. Pelvic MR venogram demonstrated a 3.5 cm high-grade stenosis of the right external iliac vein, concerning for possible prior thrombotic disease. His strokes were deemed most likely a result of paradoxical emboli originating in the pelvis at the site of right external iliac vein stenosis. The patient ultimately opted for PFO closure for secondary stroke prevention, as he wished to continue daily cycling. This case highlights the importance of neurohospitalists considering iliac vein stenosis as a potential cause of embolic stroke of undetermined source, especially in young patients who are avid cyclists, as part of a thorough vascular workup.

A Renaissance in Modern and Future Endovascular Stroke Care.

Acute ischemic stroke continues to be a major cause of death and disability globally. Although the concept of endovascular treatment of ischemic stroke is relatively new, current evidence from high-quality randomized trials suggests a significant improvement in the clinical outcome with mechanical thrombectomy up to 24 hours from the stroke onset. There has been a paradigm shift from medical management to mechanical thrombectomy which is now considered standard of care in eligible patients. Not surprisingly, there has been a constant effort to further improve stroke care in the last few years with a common goal of ultra-rapid intervention along with highly effective revascularization methods. Currently, it is one of the most dynamic and rapidly changing subspecialties in the field of medicine with significant advances in all aspects of acute stroke treatment starting from triage in the field to poststroke rehabilitation.

Crossing the Virtual Chasm: Practical Considerations for Rethinking Curriculum, Competency, and Culture in the Virtual Care Era.

Virtual care, introduced previously as a replacement for in-person visits, is now being integrated into clinical care delivery models to complement in-person visits. The COVID-19 pandemic sped up this process. The rapid uptake of virtual care at the start of the pandemic prevented educators from taking deliberate steps to design the foundational elements of the related learning environment, including workflow, competencies, and assessment methods. Educators must now pursue an informed and purposeful approach to design a curriculum and implement virtual care in the learning environment. Engaging learners in virtual care offers opportunities for novel ways to teach and assess their performance and to effectively integrate technology such that it is accessible and equitable. It also offers opportunities for learners to demonstrate professionalism in a virtual environment, to obtain a patient's history incorporating interpersonal and communication skills, to interact with multiple parties during a patient encounter (patient, caregiver, translator, telepresenter, faculty member), to enhance physical examination techniques via videoconferencing, and ideally to optimize demonstrations of empathy through "webside manner." Feedback and assessment, important features of training in any setting, must be timely, specific, and actionable in the new virtual care environment. Recognizing the importance of integrating virtual care into education, leaders from across the United States convened on September 10, 2020, for a symposium titled, "Crossing the Virtual Chasm: Rethinking Curriculum, Competency, and Culture in the Virtual Care Era." In this article, the authors share recommendations that came out of this symposium for the implementation of educational tools in the evolving virtual care environment. They present core competencies, assessment tools, precepting workflows, and technology to optimize the delivery of high-quality virtual care that is safe, timely, effective, efficient, equitable, and patient-centered.

Modeling the Cost of Teleneonatology from the Health System Perspective.

Introduction: Teleneonatology (TN) allows remote neonatologists to provide real-time audio-video telemedicine support to community hospitals when neonates require advanced resuscitation or critical care. Currently, there are no published economic evaluations of U.S. TN programs. Objective: To evaluate the cost of TN from the perspective of the health care system. Methods: We constructed a decision tree comparing TN to usual care for neonates born in hospitals without a neonatal intensive care unit (NICU) who require consultation. Our outcome of interest was total cost per patient, which included the incremental cost of a TN program, the cost of medical transport, and the cost of NICU or non-NICU hospitalization. We performed threshold sensitivity analyses where we varied each parameter to determine whether the base-case finding reverted. Results: For neonates requiring consultation after birth in a hospital without a NICU, TN was less costly ($16,878) than usual care ($28,047), representing a cost-savings of $11,168 per patient. Sensitivity analyses demonstrated that at least one of the following conditions would need to be met for TN to no longer be cost saving compared to usual care: transfer rate with usual care <12% (base-case = 82%), TN reducing the odds of transfer by <8% (base-case = 52%), or TN cost exceeding $12,989 per patient (base-case = $1,821 per patient). Conclusions: Economic modeling from the health system perspective demonstrated that TN was cost saving compared to usual care for neonates requiring consultation following delivery in a non-NICU hospital. Understanding the cost savings associated with TN may influence organizational decisions regarding implementation, diffusion, and retention of these programs.

Accuracy of Simulated Research Tasks by Community Hospitals Participating in a Multicenter Telemedicine Trial.

Background/Aims: Clinical trials evaluating facility-to-facility telemedicine may include sites that have limited research experience. For the trial to be successful, these sites must correctly perform research-related tasks. This study aimed to determine whether health care professionals at community hospitals could accurately identify simulated study eligible patients and submit data to a research coordinating center. Methods: Twenty-seven community hospitals in the United States and Canada participated in this study. An electronic survey was sent to one designated health care professional at each site. The survey included a description of trial eligibility criteria and five written neonatal resuscitation scenarios. For each scenario, the participant determined whether the neonate was study eligible. One scenario required participants to submit 14 data elements to the coordinating center. Accuracy of study eligibility and data submission was summarized using standard descriptive statistics. Results: The survey response rate was 100% (27/27). Overall accuracy in determining study eligibility was 89% (120/135), and accuracy varied across the five scenarios (range 82-93%). Overall accuracy of data submission was 92% (310/336). Data were >95% accurate for 9 of the 14 data elements, with 100% accuracy achieved for 6 data elements. These results were used to clarify eligibility criteria, inform database design, and improve training materials for the subsequent clinical trial. Conclusions: Health care professionals at community hospitals accurately determined trial eligibility and submitted study data based on written clinical scenarios. Research teams conducting telemedicine trials with community hospitals should consider completing pre-trial simulation activities to identify opportunities for improving trial processes and materials.
