Telestroke—the promise and the challenge. Part two—expansion and horizons

Telerehabilitation - historical perspectives and conceptual framework in reference to neurological disorders: A narrative review

BACKGROUND

Telerehabilitation as a new subdiscipline of telehealth is the application of information technology to support and deliver rehabilitation services via two-way or multipoint interactive online telecommunication technology. This enables the therapist to optimize the timing, intensity, and duration of therapy which is often not possible within the constraints of face-to-face treatment protocols in current health systems.

OBJECTIVE

To review the historical perspective and conceptual framework of telerehabilitation in neurological disorders.

METHODS

A narrative review of the literature was performed for the historical perspective and a systematic review of the conceptual framework was performed using the PRISMA guidelines on chronic neurological disorders; multiple sclerosis, spinal cord injury, stroke, Parkinson's disease, cognitive impairment, and headaches. The search included articles from the past 20 years (2004 to 2024).

RESULTS

Telerehabilitation dates back to the 1960s and early 1970s. Documented effective interventions were mostly on therapies for speech disorders. The conceptual framework consisted of three major components of telerehabilitation programmes including development, implementation, and evaluation. The COVID-19 pandemic suddenly made telerehabilitation come to the limelight because physical distancing became necessary. Out of the 110,000 articles downloaded, 43 met the inclusion criteria for review on the conceptual framework of telerehabilitation in relation to neurological disorders. The articles discussed multiple sclerosis (2), spinal cord disorders (1), stroke (17), Parkinson's disease (15), headaches (3), and cognitive disorders (5). All articles reviewed assessed the effectiveness of telemedicine except for the articles on multiple sclerosis and spinal cord disorders which examined the interphase between the technology and the end users.

CONCLUSION

The future of telerehabilitation looks promising with the subsequent integration of innovative tools and applications. This will require the adaption of technology, continuous capacity building, education, and training of healthcare professionals to ensure that they are adequately equipped with the necessary skills to provide quality virtual reality rehabilitation care.

Implementing Telestroke in the Inpatient Setting: Identifying Factors for Success

BACKGROUND

Inpatient telestroke programs have emerged as a solution to provide timely stroke care in underserved areas, but their successful implementation and factors influencing their effectiveness remain underexplored. This study aimed to qualitatively evaluate the perspectives of inpatient clinicians located at spoke hospitals participating in a newly established inpatient telestroke program to identify implementation barriers and facilitators.

METHODS

This was a formative evaluation relying on semistructured qualitative interviews with 16 inpatient providers (physicians and nurse practitioners) at 5 spoke sites of a hub-and-spoke inpatient telestroke program. The Integrated-Promoting Action on Research Implementation in Health Services framework guided data analysis, focusing on the innovation, recipients, context, and facilitation aspects of implementation. Interviews were transcribed and coded using thematic analysis.

RESULTS

Fifteen themes were identified in the data and mapped to the Integrated-Promoting Action on Research Implementation in Health Services framework. Themes related to the innovation (the telestroke program) included easy access to stroke specialists, the benefits of limiting patient transfers, concerns about duplicating tests, and challenges of timing inpatient telestroke visits and notes to align with discharge workflow. Themes pertaining to recipients (care team members and patients) were communication gaps between teams, concern about the supervision of inpatient telestroke advanced practice providers and challenges with nurse empowerment. With regard to the context (hospital and system factors), providers highlighted familiarity with telehealth technologies as a facilitator to implementing inpatient telestroke, yet highlighted resource limitations in smaller facilities. Facilitation (program implementation) was recognized as crucial for education, standardization, and buy-in.

CONCLUSIONS

Understanding barriers and facilitators to implementation is crucial to determining where programmatic changes may need to be made to ensure the success and sustainment of inpatient telestroke services.

Sustaining telecare consultations in nurse-led clinics: Perceptions of stroke patients and advanced practice nurses: A qualitative study

Objective

The ongoing pandemic has accentuated the use of telecare services; however, only limited progress has been made in understanding the barriers and facilitators to using these services. In order to move towards sustaining such essential services, the present study aimed to ascertain the experiences of stroke survivors and healthcare providers regarding the utilization of a post-stroke telecare service in Hong Kong.

Methods

Interpretive description was employed for this study. Semi-structured discussions and interviews were undertaken with nine stroke survivors and four stroke nurses who delivered the telecare services. The principles of thematic analysis were inductively followed to analyse the data. The Standards for Reporting Qualitative Research checklist was used to guide the reporting of the data.

Results

Three themes emerged: (a) pre-existing post-discharge service pathways; (b) push factors/facilitators for telecare usage; and (c) barriers to telecare usage. Overall, the telecare service was considered a significant alternative and one that complements conventional face-to-face follow-ups. Stroke survivors were motivated to use the service because it was convenient and flexible. However, significant barriers exist, including technical issues and a lack of guidelines and training opportunities for healthcare providers.

Conclusions

Although telecare is still evolving, several factors drive stroke survivors to use the service. Attention needs to be paid to the emerging barriers to improve long-term usage of the service. Clear guidelines are needed to underpin the development and implementation of telecare services.

The Effectiveness of Telerehabilitation on Balance and Functional Mobility in Patients with Stroke: A Systematic Review and Meta-Analysis

Objective

The aim of this systematic review and meta-analysis was to investigate the effectiveness of telerehabilitation on improving balance and functional mobility in stroke survivors.

Methods

Comprehensive searching was conducted from inception to May 2022. The inclusion criteria were studies evaluating the effectiveness of telerehabilitation in stroke survivors. Data regarding participants, intervention, outcome measures, and main results were extracted. PEDro scale and the Grading of Recommendations Assessment Development and Evaluation (GRADE) were used to assess the methodological quality and quality of evidence, respectively.

Data Analysis

A total of fourteen articles) 594 patients) were included. A meta-analysis using a random-effect model was performed on thirteen studies )530 patients). Standardized mean difference (SMD) with 95% confidence interval (CI) was calculated for balance and functional mobility. Results: PEDro scale revealed ten good-quality studies, three fair-quality studies, and one poor-quality study. According to the available evidence, telerehabilitation has a small effect size in improving both balance (SMD 0.33 [95% CI 0.03 to 0.63]; P =0.03; low quality of evidence) and functional mobility (SMD 0.27 [95% CI 0.02 to 0.52]; P =0.03; low quality of evidence).

Conclusion

Telerehabilitation may improve balance and functional mobility in stroke survivors. However, it is evident that more high-quality research is required due to the existence of low to very low-quality evidence with limited confidence in the effect estimate.

Telestroke Infrastructure, Processes, and Support Needs: A Survey of Hospitals in Five States

Introduction: Telestroke has been shown to be a cost-effective approach to promoting use and timeliness of evidence-based treatment. However, adoption of telestroke has been relatively low. Several barriers to telestroke implementation have been previously identified in the literature. These barriers, and the strategies needed to overcome them, may vary across hospitals. Our study aimed to examine telestroke programs to identify opportunities for future research and efforts to promote effective implementation and sustainment of telestroke services. Methods: We surveyed hospitals in five states to capture information about the current status of the hospital's telestroke program; the model(s) of delivery being used (e.g., hub-and-spoke and third-party vendor); and telestroke infrastructure, processes, and implementation strategies. The survey included both closed-ended and open-ended response options. Descriptive results are presented, complemented with illustrative examples of open-ended responses. Results: We received 89 responses, each representing a different hospital. Approximately one-third of telestroke programs in our sample began between 2018 and 2020. More than two-thirds reported participating in a collaboration with other organizations to improve telestroke services. The most commonly reported, high-priority topics for additional guidance involved monitoring process measures, using performance indicators for improvement, and sharing data from measures with physicians. Discussion: Results complement prior studies, specifically about impacts of COVID-19 on telestroke programs and capabilities that hospitals most need assistance with. Challenges faced and guidance needed differ across hospitals, suggesting a need for a tailored support. The results also suggest more work is needed to understand factors that threaten sustainability of telestroke programs.

Physical Activity Level and Perspectives of Participants Transitioning from Onsite to Virtual Cardiac Rehabilitation during the Early COVID-19 Pandemic: A Mixed-Method Study

This mixed-method study aimed to compare physical activity (PA) patterns of a cross-over cardiac rehabilitation (CR) cohort with a center-based CR cohort and to explore barriers and facilitators of participants transitioning and engaging in virtual CR. It included the retrospective self-reported PA of a cross-over CR cohort (n = 75) and a matched center-based CR cohort (n = 75). Some of the participants included in the cross-over cohort (n = 12) attended semi-structured focus group sessions and results were interpreted in the context of the PRECEDE-PROCEED model. Differences between groups were not observed (p > 0.05). The center-based CR cohort increased exercise frequency (p = 0.002), duration (p = 0.007), and MET/minutes (p = 0.007) over time. The cross-over cohort increased exercise duration (p = 0.04) with no significant change in any other parameters. Analysis from focus groups revealed six overarching themes classified under predisposing factors (knowledge), enabling factors (external support, COVID-19 restrictions, mental health, personal reasons/preferences), and reinforcing factors (recommendations). These findings suggest an improvement of the PA levels of center-based CR cohort participants pre-pandemic and mitigated improvement in those who transitioned to a virtual CR early in the pandemic. Improving patients’ exercise-related knowledge, provider endorsements, and the implementation of group videoconferencing sessions could help overcome barriers to participation in virtual CR.

Structural Inequities for Historically Underserved Communities in the Adoption of Stroke Certification in the United States

Importance

Stroke centers are associated with better outcomes. There is substantial literature surrounding disparities in stroke outcomes for underserved populations. However, the existing literature has focused primarily on discrimination at the individual or institutional level, and studies of structural discrimination in stroke care are scant.

Objective

To examine differences in hospitals' likelihood of adopting stroke care certification between historically underserved and general communities.

Design, Setting, and Participants

This study combined a data set of hospital stroke certification from all general acute nonfederal hospitals in the continental US from January 1, 2009, to December 31, 2019, with national, hospital, and census data to define historically underserved communities by racial and ethnic composition, income distribution, and rurality. For all categories except rurality, communities were categorized by the composition and degree of segregation of each characteristic. Cox proportional hazard models were then estimated to compare the hazard of adopting stroke care certification between historically underserved and general communities, adjusting for population size and hospital bed capacity. Data were analyzed from June 2021 to April 2022.

Main Outcomes and Measures

Hospitals' likelihood of adopting stroke care certification.

Results

A total of 4984 hospitals were included. From 2009 to 2019, the total number of hospitals with stroke certification grew from 961 to 1763. Hospitals serving Black, racially segregated communities had the highest hazard of adopting stroke care certification (hazard ratio [HR], 1.67; 95% CI, 1.41-1.97) in models not accounting for population size, but their hazard was 26% lower than among those serving non-Black, racially segregated communities (HR, 0.74; 95% CI, 0.62-0.89) in models controlling for population and hospital size. Adoption hazard was lower in low-income communities compared with high-income communities, regardless of their level of economic segregation, and rural hospitals were much less likely to adopt any level of stroke care certification relative to urban hospitals (HR, 0.43; 95% CI, 0.35-0.51).

Conclusions and Relevance

In this analysis of stroke certification adoption across acute care hospitals in the US from 2009 to 2019, hospitals in low-income and rural communities had a lower likelihood of receiving stroke certification than hospitals in general communities. Hospitals operating in Black, racially segregated communities had the highest likelihood of adopting stroke care, but because these communities had the largest population, patients in these communities had the lowest likelihood of access to stroke-certified hospitals when the model controlled for population size. These findings provide empirical evidence that the provision of acute neurological services is structurally inequitable across historically underserved communities.

Telehealth for Comprehensive Care of Acute Neurologic Disorders

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.

Cognitive telerehabilitation in neurological patients: systematic review and meta-analysis

Telerehabilitation (TR) seems to be an encouraging solution for the delivery of cognitive treatments in patients with neurological disorders. This study was aimed to analyze and synthesize the evidence on the efficacy of cognitive TR interventions in patients with neurological diseases, compared with conventional face-to-face rehabilitation. From a total of 4485 records, 9 studies met the inclusion criteria for qualitative analysis. At the end of the process, 7 studies remained for quantitative analysis. By comparing TR with face-to-face treatments for cognitive impairments, we assessed improvements in global cognitive domain (Mini Mental State Exam) (MD = −0.86; 95% CI −2.43, 0.72, I² = 0%), in learning and memory domains (SMD = 0.26, 95% CI −0.22, 0.74, I² = 24%), in verbal fluency (SMD = 0.08, 95% CI −0.47, 0.62, I² = 0%), and in executive functions (i.e., problem-solving, central processing speed and working memory) (SMD = 0.38, 95% CI 0.06, 0.71, I² = 0%). In all the included studies, improvement in the performance of the TR groups was comparable to that achieved through face-to-face intervention. Significant differences between those two modalities of providing treatments were observed for working memory and total executive function comparison, in favor of TR. The results of this study can sustain the efficacy of TR and its application for the treatment of neurological patients, especially when treated for executive function impairments.

The Utility of Remote Video Technology in Continuing Neurosurgical Care in the COVID-19 Era: Reflections from the Past Year

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.

CTA Protocols in a Telestroke Network Improve Efficiency for Both Spoke and Hub Hospitals

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.

The Potential of Telemedicine to Improve Pediatric Concussion Care in Rural and Remote Communities in Canada

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.

Electronic Alberta Stroke Program Early CT score change and functional outcome in a drip-and-ship stroke service

Background

Debate continues as to whether patients with acute ischemic stroke with (suspected) large vessel occlusion benefit from direct referral versus secondary transportation.

Aims

To analyze the change in early infarct signs, collaterals, and acute ischemia volume and their association with transfer time and functional outcome.

Methods

We 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.

Results

102 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).

Conclusions

Patient 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.

Technological innovation for prehospital stroke triage: ripe for disruption

Background

With 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.

Methods

This review explores existing, fledgling, and potential future technologies for application in the prehospital space.

Results

The 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.

Conclusion

The 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.

Telerehabilitation for Stroke Survivors: Systematic Review and Meta-Analysis

Background

Telerehabilitation is an emerging technology through which medical rehabilitation care can be provided from a distance.

Objective

This systematic review and meta-analysis aims to investigate the efficacy of telerehabilitation in poststroke patients.

Methods

Eligible randomized controlled trials (RCTs) were identified by searching MEDLINE, Cochrane Central, and Web of Science databases. Continuous data were extracted for relevant outcomes and analyzed using the RevMan software as the standardized mean difference (SMD) and 95% CI in a fixed-effect meta-analysis model.

Results

We included 15 studies (1339 patients) in our systematic review, while only 12 were included in the pooled analysis. The combined effect estimate showed no significant differences between the telerehabilitation and control groups in terms of the Barthel Index (SMD –0.05, 95% CI –0.18 to 0.08), Berg Balance Scale (SMD –0.04, 95% CI –0.34 to 0.26), Fugl-Meyer Upper Extremity (SMD 0.50, 95% CI –0.09 to 1.09), and Stroke Impact Scale (mobility subscale; SMD 0.18, 95% CI –0.13 to 0.48]) scores. Moreover, the majority of included studies showed that both groups were comparable in terms of health-related quality of life (of stroke survivors), Caregiver Strain Index, and patients’ satisfaction with care. One study showed that the cost of telerehabilitation was lower than usual care by US $867.

Conclusions

Telerehabilitation can be a suitable alternative to usual rehabilitation care in poststroke patients, especially in remote or underserved areas. Larger studies are needed to evaluate the health-related quality of life and cost-effectiveness with the ongoing improvements in telerehabilitation networks.

Multidisciplinary amyotrophic lateral sclerosis telemedicine care: The store and forward method

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.

Telestroke Adoption Among Community Hospitals in North Carolina: A Cross-Sectional Study

OBJECTIVE

This study identifies community and hospital characteristics associated with adoption of telestroke among acute care hospitals in North Carolina (NC).

METHODS

Our sample included 107 hospitals located in NC. Our analytic dataset included variables from the American Hospital Association (AHA) annual survey, AHA Health IT supplement, Healthcare Cost Report Information System, and Centers for Disease Control and Prevention's WONDER online database. We supplemented our secondary sources with data on telestroke adoption and market-level variables developed for NC. We used the Consolidated Framework for Implementation Research and previous telehealth studies to guide selection of variables. We conducted a multivariate logistic regression to determine associations with telestroke adoption.

RESULTS

Proportion of discharges that are Medicare (odds ratio [OR] = 1.93, P < .04) and total operating margin (OR = 2.89, P = .00) were positively associated with telestroke adoption. Critical access hospital status was positively associated with telestroke adoption, although not at P < .05 (OR = 5.61, P = .07). Distance to the nearest hospital with a telestroke program (OR = .91, P = .01) and volume of emergency department visits (OR = .98, P < .05) were both negatively associated with telestroke adoption.

CONCLUSIONS

Our study is novel in its focus on telestroke adoption and use of variables not included in previous telehealth analyses. Our findings suggest some hospitals have neither the financial resources nor the ability to pool resources for acquiring needed technology, and differences in adoption may result in geographic inequities in access to telestroke services.

Robot Assisted Surgical Ward Rounds: Virtually Always There

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.

Delays in the Air or Ground Transfer of Patients for Endovascular Thrombectomy

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.
