An exploratory study investigating the barriers, facilitators, and demands affecting caregivers in a telemedicine integrated ambulance-based setting for stroke care.
This study investigates the impact of telemedicine on workload, teamwork, workflow, and communication of geographically distributed caregivers delivering stroke care in ambulance-based telemedicine. Simulated stroke sessions were conducted with selected caregivers, then followed with a survey and interviews. Findings showed that barriers included frustration with equipment, the loss of personal connection of the neurologists with the patients, and physical constraints in the ambulance. Facilitators included live visual communication increasing teamwork and efficiency, the ease of access to neurologist, increased flexibility, and high overall satisfaction and usability.

Door-in-door-out process times at primary stroke centers in Chicago.
This study sought to identify modifiable predictors of door-in-door-out times for transfer of acute stroke patients from primary stroke centers to comprehensive stroke centers using 3 Chicago-region primary stroke centers as a model. A retrospective analysis of consecutive patients with acute stroke from February 2018 to January 2020 who required transfer from 1 of 3 primary stroke centers to 1 of 3 affiliated comprehensive stroke centers was conducted. Of 191 total patients, 67.9% arrived by emergency medical services and 57.4% during off-hours. Telestroke was performed in 84.2% of patients, 30.5% received alteplase, and 48.4% underwent a computed tomography (CT) at the primary stroke center. The median door-in-door-out time was 148.5 minutes. The largest contributors to longer door-in-door-out times were CT to CT angiography time, transfer center contact to ambulance request time, ambulance request to arrive time, and transfer ambulance at primary stroke center. Other factors included CT angiography performed at the primary stroke center, walk-in arrival mode, administration of intravenous alteplase request by primary stroke center, and ambulance request by the primary stroke center.

National trends in telestroke utilization in a US commercial platform prior to the COVID-19 pandemic.
In this study, the objective was to describe characteristics of telestroke consultations among a national sample of telestroke sites on one of the most commonly used common vendor platforms, prior to the COVID-19 public health emergency. The investigators concluded that among spoke sites using a commercial telestroke platform over a seven-year time horizon, times to consult start and alteplase bolus decreased over time. Similar to academic networks, duration of telestroke participation in this commercial network was associated with faster alteplase delivery, suggesting practice improves performance.

Prehospital comprehensive stroke center vs primary stroke center triage in patients with suspected large vessel occlusion stroke.
This study’s objective was to evaluate the association of a regional prehospital transport policy that directly triages patients with suspected large vascular occlusion (LVO) stroke to the nearest comprehensive stroke center with rates of endovascular therapy (EVT). This retrospective, multicenter preimplementation-postimplementation study used an interrupted time series analysis to compare treatment rates before and after implementation in patients with acute ischemic stroke (AIS) arriving at 15 primary stroke centers and 8 comprehensive stroke centers in Chicago, Illinois, via emergency medical services (EMS) transport from December 1, 2017, to May 31, 2019. Among 7709 individuals with stroke, 663 with AIS arrived within 6 hours of stroke onset by EMS transport. The EVT rate increased overall among patients with AIS postimplementation and among EMS-transported patients with AIS within 6 hours of onset. There were no differences in EVT rates in patients not arriving by EMS within the 6- to 24-hour window or by interhospital transfer or walk-in.

Thyroid hormone therapy and incident stroke.
This study’s objective was to determine the relationship between thyroid hormone treatment intensity and incidence of atrial fibrillation (AFIB) and stroke. This retrospective cohort study used data from the Veterans Health Administration between 2004 and 2017, with a median follow-up of 59 months. Total study population was comprised of 733,208 thyroid hormone users aged ≥18 years with at least 2 thyroid stimulating hormone (TSH) measurements between thyroid hormone initiation and incident event (atrial fibrillation or stroke) or study conclusion. Overall, 71,333 (11.08%) developed incident atrial fibrillation and 41,931 (6.32%) stroke. Higher incidence of stroke was associated with low thyroid-stimulation hormone (TSH) or high free thyroxine (T4) levels compared to patients with normal TSH or T4 levels. Risk of developing AFIB and stroke was cumulative over time for patients with exogenous hyperthyroidism or hypothyroidism.

Validation of an electronic trigger to measure missed diagnosis of stroke in emergency departments.
Diagnostic errors are major contributors to preventable patient harm. In this study, the investigators validated the use of an electronic health record (EHR)-based trigger (e-trigger) to measure missed opportunities in stroke diagnosis in emergency departments (EDs). The investigators concluded that a symptom-disease pair-based e-trigger identified missed diagnoses of stroke with a modest positive predictive value, underscoring the need for chart review validation procedures to identify diagnostic errors in large data sets.

Hospital to home transition for patients with stroke under bundled payments.
In this paper, the authors describe COMprehensive Post-Acute Stroke Services (COMPASS), a comprehensive transitional care intervention focused on discharge from the acute care setting to home. The COMPASS care model is aligned with the incentive structures and essential components of bundled payments in terms of care coordination, patient assessment, patient and family involvement, and continuity of care. They concluded that ongoing evaluation will inform the design of incorporating COMPASS-like transitional care interventions into a stroke bundle.

Depression as a risk factor for incident ischemic stroke among HIV-positive veterans in the veterans aging cohort study.
Background HIV infection and depression are each associated with increased ischemic stroke risk. Whether depression is a risk factor for stroke within the HIV population is unknown. In this study the investigators examined depression as a risk factor for incident ischemic stroke among HIV-positive veterans in the veterans aging cohort study. The investigators concluded that depression is associated with an increased risk of stroke among HIV-positive people after adjusting for sociodemographic characteristics, traditional cerebrovascular risk factors, and HIV-specific factors.

Emergency department telemedicine consults decrease time to interpret computed tomography of the head in a multi-network cohort.
Telemedicine can improve access to emergency stroke care in rural areas, but the benefit of telemedicine across different types and models of telemedicine networks is unknown. The objectives of this study were to (1) identify the impact of telemedicine on ED stroke care, (2) identify if telemedicine impact varied by network, and (3) describe the variation in process outcomes by telemedicine across EDs.

Strategy for reliable identification of ischaemic stroke, thrombolytics and thrombectomy in large administrative databases.
Administrative data are frequently used in stroke research. Ensuring accurate identification of patients who had an ischaemic stroke, and those receiving thrombolysis and endovascular thrombectomy (EVT) is critical to ensure representativeness and generalisability. In this study, the investigators examined differences in patient samples based on mode of identification, and proposed a strategy for future patient and procedure identification in large administrative databases.

Regional changes in patterns of stroke presentation during the COVID-19 pandemic.
The authors sought to determine the effect of the coronavirus pandemic on patterns of stroke patient presentation and quality of care. They analyzed data from 25 New England hospitals: one urban, academic, comprehensive stroke center and telestroke hub, and 24 spoke hospitals in the same telestroke network. They included all telestroke consultations from the 24 spokes, and stroke admissions to the comprehensive stroke center hub from November 2019 through April 2020. They compared rates of presentation, timeliness presentation, and quality of care pre- versus post-March 2020. They also examined trends in patient demographics, stroke severity, timeliness, diagnosis including large vessel occlusion, alteplase use, and endovascular thrombectomy among eligible subjects. Among 1248 patient presentations, telestroke consultations and ischemic stroke patient admissions decreased through the hub and spoke network. Age and stroke severity were unchanged during the study period. However, rates of adherence for the quality measures dysphagia screening, early antithrombotic initiation, and early venous thromboembolism prophylaxis were reduced during the pandemic.

Post-acute care use patterns among hospital service areas by older adults in the United States: a cross-sectional study.
This study examined post-stroke acute care patterns across Hospital Service Areas among a national stroke cohort of Medicare beneficiaries to determine drivers of variation in post-acute care service utilization. Data was extracted from 2013 to 2014 (174,498 total records across 3232 Hospital Service Areas). Patients’ residence ZIP codes were linked to the facility ZIP code where care was received. Patients were considered a “traveler” if they did not live in the Hospital Service Area where they received care. Only 23.5% of all patients received care in skilled nursing-only Hospital Service Areas although 73.4% of all Hospital Service Areas were skilled nursing-only. Thirty-five percent of all patients traveled to a different Hospital Service Area from their residence. Patients living in skilled nursing-only Hospital Service Areas had more than 5 times the odds of traveling compared to those living in Hospital Service Areas with skilled nursing, inpatient rehabilitation, and long-term care hospital services.

Language preference does not influence stroke patients' symptom recognition or emergency care time metrics.
The objective of this study was to determine whether acute ischemic stroke (AIS) patients' language preference was associated with differences in time from symptom discovery to hospital arrival, activation of emergency medical services, door-to-imaging time (DTI), and door-to-needle (DTN) time. The investigators concluded that consistent with prior reports examining disparities in care, a systems-based approach to acute stroke prevents differences in hospital-based metrics.

The cost of implementing and sustaining the COMprehensive Post-Acute Stroke Services model.
This study compares the outcomes of using the COMprehensive Post-Acute Stroke Services (COMPASS) model, a transitional care intervention for stroke patients discharged to home against status quo postacute stroke care in a cluster-randomized trial in 40 hospitals in North Carolina. Hospital-level costs associated with implementing and sustaining COMPASS were examined during a 1-year period. Out of 40 hospitals, 22 hospitals were actively engaged in COMPASS. A 10% higher stroke patient volume was associated with 5.1% lower COMPASS costs per patient. About half of hospitals (N = 10) reported postacute clinic visits as their highest cost activity, while 7 hospitals reported case ascertainment as their highest cost activity. The authors estimated that based on average costs of COMPASS and readmissions, COMPASS could lower net costs if the model can prevent about 6 readmissions per year.

Gender differences in association of prescription opioid use and mortality: a propensity-matched analysis from the REasons for Geographic And Racial Differences in Stroke (REGARDS) prospective cohort.
Prescription opioids (PO) have been widely used for chronic non-cancer pain, with commensurate concerns for overdose. The long-term effect of these medications on non-overdose mortality in the general population remains poorly understood. This study's objective was to examine the association of prescription opioid use and mortality in a large cohort, accounting for gender differences and concurrent benzodiazepine use, and using propensity score matching.

Comparison of functional status improvements among patients with stroke receiving postacute care in inpatient rehabilitation vs skilled nursing facilities.
This cohort study compared functional status improvements of poststroke patients who either went to an inpatient rehabilitation facility (IRF) or a skilled nursing facility (SNF). The study used data from Medicare claims for stroke from January 2013 through November 2014. A total of 99,185 patients were studied. Patients admitted to SNFs tended to be older, female, and had a longer hospital length of stay than those admitted to IRFs. Stroke patients admitted to IRFs had larger improvements for mobility score points and for self-care on admission compared with those admitted to SNFs. There was found to be no statistical difference in the odds of 30- to 365-day mortality.

Patients with greater stroke severity and premorbid disability are less likely to receive therapist consultations and intervention during acute care hospitalization.
The goal of this single-center longitudinal observational study was to estimate the proportion of and factors associated with receipt of therapist consultations and interventions during acute care hospitalization following ischemic and hemorrhagic stroke. Findings showed that approximately 1 in 4 study participants with acute stroke received neither a consultation nor an intervention. The authors conclude that efforts to improve the delivery of acute care therapy services are needed to optimize care for these people.

Social network structure in young stroke survivors with aphasia: a case series report.
The purpose of this study was to profile the social networks of four young adult stroke survivors with aphasia. Results showed that pre-stroke friendships were dissolved or reduced at the onset of aphasia. The most impaired persons with aphasia spent most of their days in isolation without a consistent communication partner. This study result suggests that young adult stroke survivors with aphasia have significant changes in their social network structure after stroke, but it is unclear if the observed change in social network structure is more related to age or level of communication impairment.

Role of diabetes and insulin use in the risk of stroke and acute myocardial infarction in patients with atrial fibrillation: a Medicare analysis.
This study examined the role of diabetes and insulin use in the risk of stroke and acute myocardial infarction (AMI) in patients with atrial fibrillation (AF). A cohort of Medicare beneficiaries newly diagnoses with AF from 2011 to 2013 were identified. The cohort was divided into those with diabetes requiring insulin (6.7%), those with diabetes not requiring insulin (31.3%) and non-diabetics (62%). Diabetics requiring insulin were at the greatest risk of stroke and AMI, and diabetics not requiring insulin were at slightly lower risk, but non-diabetics had the lowest risk.

Evaluation of the experience of spoke hospitals in an academic telestroke network.
Implementation of telestroke has been associated with improved thrombolysis rates and clinical outcomes in remote or neurologically underserved spoke hospitals. Yet, the experience of spoke hospitals using telestroke has not been well described. In this study, the investigators sought to characterize spoke hospitals' perceptions of telestroke to understand perceived advantages, challenges, and barriers to use.
