Inpatient Teleneurology Follow-up Has Comparable Outcomes to In-Person Neurology Follow-up.

Background and Objectives: Community emergency departments often transfer patients for lack of neurology coverage, potentially burdening patients and accepting facilities. Telestroke improves access to acute stroke care, but there is a lack of data on inpatient teleneurology and telestroke care. Methods: From our prospective telestroke registry, we retrospectively reviewed 3702 consecutive patients who were seen via telestroke between September 2015 and December 2018. Patients who required transfer after initial telestroke evaluation or who were kept at hospitals without consistent neurology coverage were excluded from analysis. We compared baseline demographics, clinical characteristics, and hospital outcomes in patients who were subsequently followed remotely by a teleneurology neurohospitalist and those followed in person by a neurohospitalist. Results: There were 447 (23%) patients followed by a teleneurology neurohospitalist and 1459 (77%) patients followed in person by a neurohospitalist. Both groups presented with similar stroke severity. In multivariate analysis, there were no significant differences in discharge disposition, stroke readmission rates, or 90-day modified Rankin Scale (mRS) scores. Length of stay was shorter with teleneurology follow-up. In the subgroup of patients who received tissue plasminogen activator, patients showed no differences in outcomes and had similar complication rates. Teleneurology follow-up resulted in a 3% transfer rate for higher level of care after admission. There remained no difference in outcomes in a subanalysis without Comprehensive Stroke Centers. A higher proportion of non-Hispanic Black patients and a lower proportion of Hispanic patients in the teleneurology follow-up group were possibly due to spoke location demographics. Discussion: Teleneurology follow-up resulted in comparable outcomes to in-person neurology follow-up, with few transfers after admission. For select neurology and ischemic stroke patients, teleneurology follow-up provides an alternative to transfer for hospitals lacking neurology coverage.

Patients transferred within a telestroke network for large-vessel occlusion.

INTRODUCTION: In a telestroke network, patients at a referring hospital (RH) with large-vessel occlusion (LVO) are transferred to a comprehensive stroke centre (CSC) for endovascular thrombectomy (EVT). However, a significant number of patients do not ultimately undergo thrombectomy after CSC arrival. METHODS: Within a 17-hospital telestroke network, we retrospectively analysed patients with suspected or confirmed LVO transferred to a CSC, and characterized the reasons why these patients did not undergo EVT based on the 2019 American Heart Association guidelines. RESULTS: Of 400 patients transferred to our hub, 68 (17%) were based on vascular imaging at RH. Time from RH arrival to neuroimaging was significantly longer in patients that underwent both computed tomography (CT) and CT angiography of the brain and neck compared to only CT of the brain (53 vs 13 minutes, p < 0.05). Accuracy of anterior circulation LVO (ACLVO) detection based on clinical suspicion was 62% (205 of 332 patients). Among 234 ACLVO patients, overall, 175 (74%) (early window group: 123 (73%) patients and late window group: 52 (80%) patients) met at least one EVT ineligibility criterion. The reasons for EVT ineligibility varied from large core infarct (aspects <6 or core volume >70 cc on perfusion imaging in late window), low National Institutes of Health Stroke Scale (<6), distal occlusion, and poor baseline modified Rankin Scale score (>1). DISCUSSION: Instituting rapid acquisition and interpretation of vascular imaging at RHs for LVO detection and establishing benchmarks for door to vascular imaging is urgently needed for RHs.

Thrombolytic Refusal Over Telestroke.

BACKGROUND: Tissue plasminogen activator (tPA) refusal is 4%-6% for acute ischemic stroke (AIS) in the emergency department. Telestroke (TS) has increased the use of tPA for AIS but is accompanied by barriers in communication that can affect tPA consent. We characterized the incidence of tPA refusal in our TS network and its associated reasons. METHODS: Patients with AIS who were offered tPA within 4.5 hours from symptom onset according to American Heart Association guidelines were identified within our Lone Star Stroke Consortium Telestroke Registry from September 2015 to December 2018. We compared baseline characteristics and clinical outcomes between patients who refused tPA and patients who accepted tPA. RESULTS: Among the 1,242 patients who qualified for tPA and were offered treatment, 8% refused tPA. Female and non-Hispanic Black patients and patients with a prior history of stroke were more likely to decline tPA. Patients who refused tPA presented with a lower NIHSS and were associated with a final diagnosis of stroke mimic (odds ratio [OR] 0.23; 95% confidence interval [CI] 0.15-0.36). Good outcome (90-day modified Rankin Scale 0-2) was the same among patients who received tPA and those who refused (OR 0.80; 95% CI 0.42-1.54). The most common reasons for refusal were rapidly improving and mild/nondisabling symptoms and concern for potential side effects. CONCLUSION: tPA refusal over TS is comparable to previously reported rates; there was no difference in outcomes among patients who received tPA compared with those who refused. Sex and racial differences associated with an increased tPA refusal warrant further investigation in efforts to achieve equity/parity in tPA decisions.

IAT-TiMeS: Intra-Arterial Thrombectomy Transfer Metric Study in Texas.

OBJECTIVE: We aim to report intra-arterial thrombectomy transfer metrics for ischemic stroke patients that were transferred to hub hospitals for possible intra-arterial thrombectomy in multiple geographic regions throughout the state of Texas and to identify potential barriers and delays in the intra-arterial thrombectomy transfer process. METHOD: We prospectively collected data from 8 participating Texas comprehensive stroke/thrombectomy capable centers from 7 major regions in the State of Texas. We collected baseline clinical and imaging data related to the pre-transfer evaluation, transfer metrics, and post-transfer clinical and imaging data. RESULTS: A total of 103 acute ischemic stroke patients suspected/confirmed to have large vessel occlusions between December 2016 to May 2019 that were transferred to hubs as possible intra-arterial thrombectomy candidates were enrolled. A total of 56 (54%) patients were sent from the spoke to the hub via ground ambulance with 47 (46%) patients traveling via air ambulance. The median spoke arrival to hub arrival time was 174 min, median spoke arrival to departure from spoke was 131 min, and median travel time was 39 min. The spoke arrival time to transfer initiation was 68 min. CT-perfusion obtained at the spoke and earlier initiation of transfer were statistically associated with shorter transfer times. CONCLUSION: Transfer of intra-arterial thrombectomy patients in Texas may take over 4 h from spoke arrival to hub arrival. This time may be shortened by earlier transfer initiation and acceptance.

Rationale and design of a statewide telestroke registry: Lone Star Stroke Consortium Telestroke Registry (LeSteR).

INTRODUCTION: The Lone Star Stroke Consortium Telestroke Registry (LeSteR) currently consisting of 3 academic hub centres and 27 partner spokes is a statewide initiative organised by leading academic health centres in the State of Texas to understand practice patterns of acute stroke management via telestroke (TS) in Texas, a state with one of the largest rural populations in the USA. METHODS AND ANALYSIS: All patients who had presumed stroke for whom a TS consultation has been obtained in the network are entered into a web-based, Health Insurance Portability and Accountability Act-compliant database from September 2013 to present. Spokes were enrolled into LeSteR in a staggered approach in two data collection phases: a retrospective phase and a prospective phase. Basic clinical, demographic data and relevant time metrics are collected in the retrospective phase. Starting 1 September 2015, additional outcome data including 90-day modified Rankin score, readmission and 90-day disposition are obtained by a standard phone interview. From the registry initiation to 31 December 2017, there are 8089 patients who had suspected stroke in the registry. Over 60% of patients enrolled after 1 September 2015 have reported outcome data. Enrolment is still active for this registry. ETHICS AND DISSEMINATION: LeSteR is a statewide TS registry organised by academic health centres that will provide significant insight regarding the impact of TS in the State of Texas. Findings from LeSteR will provide data that can be analysed to improve the allocation of healthcare resources using TS to treat stroke in a state with one of the largest rural populations.

Variability and Delay in Telestroke Physician Alert among Spokes in a Telestroke Network: A Need for Metric Benchmarks.

INTRODUCTION: Telestroke has increased access to acute management of ischemic stroke in areas that lack stroke care expertise, yet delays persist in evaluation and treatment. We describe variation in time to alert a telestroke physician of suspected acute ischemic stroke patients potentially eligible for acute stroke therapies among community hospitals in our telestroke network, and explore demographic and spoke-related characteristics associated with delays. METHODS: From our telestroke registry, we identified suspected acute ischemic stroke patients who arrived within 6 hours of symptom onset and underwent video consultation at 1 of 17 community hospitals in our hub-and-spoke network. We compared time between patient arrival to telestroke alert (door-to-page-time) and to tissue plasminogen activator (tPA) administration for eligible patients (door-to-needle-time). We identified factors associated with prolonged metrics. RESULTS: Of 1020 cases between 9/2015 and 3/2017, 47% received tPA. Sixty percent had door-to-page-time more than 15 minutes (median 19.5; IQR, 11-34). Door-to-page-time more than 15 minutes was associated with an 8-fold increase in likelihood of door-to-needle-time more than 60 minutes. Patients with severe stroke experienced faster door-to-page-times. Hospitals with more beds had prolonged door-to-page-time. Full time in-house neurology presence, even when not covering emergent consultations, was associated with faster door-to-page-time over telestroke. Seventy-one percent of patients underwent CT brain prior to the telestroke physician alert; this scenario delayed door-to-page and door-to-needle times. CONCLUSIONS: Door-to-page-time varied considerably among spokes. Awaiting CT scan prior to alerting the telestroke consultant of a stroke code delayed metrics. Telestroke physician alert standards are needed, as are educational initiatives on acute ischemic stroke management and workflow.

Outcomes Among Patients With Ischemic Stroke Treated With Intravenous tPA (Tissue-Type Plasminogen Activator) via Telemedicine.

Background and Purpose- Telemedicine is increasingly utilized for intravenous tPA (tissue-type plasminogen activator) delivery. The comparative safety of leaving tPA-treated patients at a presenting (spoke) hospital (drip-and-stay) or transferring patients to a central treating (hub) hospital (drip-and-ship) is not established. We sought to compare outcomes between drip-and-ship and drip-and-stay patients treated with tPA via telemedicine. We hypothesized that there would be no differences in short-term outcomes of in-hospital mortality, length of stay, or discharge disposition or in 90-day outcomes between groups. Methods- We retrospectively identified patients treated with tPA at 17 spoke hospitals between September 2015 and December 2016. Demographic, clinical, and outcome data were obtained from a prospective telemedicine registry. We used negative binomial, multinomial, and logistic regression analyses to evaluate length of stay, discharge disposition, and inpatient mortality, respectively. We compared the proportion of patients with 90-day modified Rankin Scale score <2 by group. Results- Among 430 tPA-treated patients, 232 (53.9%) were transferred to the hub after treatment. The median arrival National Institutes of Health Stroke Scale score was higher for drip-and-ship (10; interquartile range, 5-18) compared with drip-and-stay patients (6; interquartile range, 4-10; P<0.001). Unadjusted length of stay was longer in drip-and-stay patients (incidence rate ratio, 0.82; 95% CI, 0.71-0.95). There were no significant differences in adjusted length of stay, hospital mortality, or discharge disposition. Among the 64% of patients with complete 90-day modified Rankin Scale score, the proportion with good outcomes (modified Rankin Scale score <2) did not differ between groups. Conclusions- We found no differences in measured outcomes between drip-and-ship and drip-and-stay patients treated in our network, although our study may be underpowered to detect small differences.

Telemedicine-guided education on secondary stroke and fall prevention following inpatient rehabilitation for Texas patients with stroke and their caregivers: a feasibility pilot study.

INTRODUCTION: The aftermath of stroke leaves many consequences including cognitive deficits and falls due to imbalance. Stroke survivors and families struggle to navigate the complex healthcare system with little assistance posthospital discharge, often leading to early hospital readmission and worse stroke outcomes. Telemedicine Guided Education on Secondary Stroke and Fall Prevention Following Inpatient Rehabilitation feasibility study examines whether stroke survivors and their caregivers find value in telerehabilitation (TR) home visits that provide individualised care and education by a multidisciplinary team after discharge from inpatient rehabilitation. METHODS AND ANALYSIS: A prospective, single arm, pilot study is designed to evaluate the feasibility of weekly TR home visits initiated postdischarge from inpatient rehabilitation. Newly diagnosed patients with stroke are recruited from a Houston-based comprehensive stroke centre inpatient rehabilitation unit, loaned an iPad with data plan and trained to use information technology security-approved videoconferencing application. After hospital discharge, six weekly TR home visits are led by rotating specialists (pharmacist, physical/occupational therapist, speech therapist, rehabilitation physician, social worker, geriatrician specialised in fracture prevention) followed by satisfaction survey on week 7. Specialists visually assess patients in real time, educate them on secondary stroke and fall prevention and suggest ways to improve function including direct medical interventions when indicated. Primary outcomes are proportion of eligible patients consenting to the study, participation rate in all six TR home visits and satisfaction score. The study started 31 December 2015 with plan to enrol up to 50 patients over 24 months. Feasibility study results will inform us as to whether a randomised controlled trial is warranted to determine efficacy of TR home visit intervention in improving stroke outcomes. ETHICS AND DISSEMINATION: Ethics approval obtained by the Institutional Review Board (IRB), Committee for the Protection of Human Subjects, IRB number: HSC-MS-14-0994. Study results will be submitted for publication in a peer-reviewed journal.

Benchmarking Telestroke Proficiency: Page-to-Needle Time Among Neurovascular Fellows and Attendings.

BACKGROUND AND PURPOSE: Formal telestroke training for neurovascular fellows (NVFs) is necessary because of growing use of telestroke technologies in the management of acute ischemic stroke; yet, educational approaches and training benchmarks are not formalized. Time between telestroke consultant page and tissue-type plasminogen activator administration (page-to-needle time, PTNT) can provide an objective measure of proficiency. We compared PTNT between NVFs and neurovascular attendings (NVAs) and evaluated changes in PTNT with experience. METHODS: We identified suspected acute ischemic stroke patients in our telestroke registry from July 2013 to December 2015 who received tissue-type plasminogen activator. Using multivariable quantile regression, we estimated the difference and 95% confidence interval in median PTNT between NVFs and NVAs. We also report the coefficient of change in PTNT over increasing number of telestroke consults. RESULTS: NVFs evaluated 53.7% of 618 tissue-type plasminogen activator cases over telestroke. NVAs had significantly shorter PTNT compared with NVFs, with a difference in median PTNT of -9 minutes (95% confidence interval, -12.3 to -5.7). This difference persisted when adjusted for relative tissue-type plasminogen activator contraindications. For each additional telestroke consult, PTNT decreased by 0.07 minutes for NVFs or NVAs (P=0.02 and <0.01, respectively). CONCLUSIONS: PTNT improves by ≈1 minute for every 14 consults for both NVFs and NVAs. Our findings support the importance of integrating telestroke training into supervised neurovascular fellowships to increase proficiency prior to independent practice and suggest that PTNT can be a benchmark for tracking proficiency.

The Benefits and Challenges of Managing Asthma in Hispanic Families in South Texas: A Mixed-Methods Study.

BACKGROUND: Understanding the experience of Hispanic parents of children diagnosed with asthma can be useful in the delivery of effective and meaningful asthma education. In order to assess the needs of Hispanic families with asthmatic children in South Texas, investigators utilized a combination of qualitative and quantitative research methods. OBJECTIVES: This study aimed (1) to assess the impact of asthma in the quality of life of Hispanic children and their families and (2) to identify barriers and challenges to asthma management as perceived by parents of children diagnosed with asthma. METHODS: A mixed-methods study included a quality-of-life survey and focus group discussions. The Children's Health Survey for Asthma (CHSA) was completed by 90 parents of children with asthma. Three focus groups were conducted with 15 low-income, Hispanic parents of asthmatic children to assess their needs and experience in managing the disease. RESULTS: Results from the CHSA showed that asthma significantly affects the quality of life of children with asthma and their families, particularly the emotional dimensions and the child's physical health. Fifty-three percent of the children had visited the emergency room, and 51% had been hospitalized due to asthma. One out of five parents had missed work, and 27% of children had missed school in the past 2 weeks due to the child's asthma. In the focus group discussions, the key themes emerging included lack of asthma knowledge, the burden of disease for asthmatic children and their families, and the importance of asthma education and self-management behaviors for asthma control. CONCLUSION: One of the main challenges faced by Hispanic families with asthmatic children is the lack of asthma-related knowledge to help understand and control their children's disease. Lack of knowledge and self-management skills lead to significant stress and anxiety among children with asthma and their parents. Results highlight that while asthma has an effect on the quality of life of children and their families, particularly on the emotional health domain, a wide dissemination of asthma management education in different settings might help prevent asthma attacks and improve symptom control among those suffering from this disease along the US-Mexico border.
