Lack of Racial, Ethnic, and Sex Disparities in Ischemic Stroke Care Metrics within a Tele-Stroke Network.

INTRODUCTION: Differences in access to stroke care and compliance with standard of care stroke management among patients of varying racial and ethnic backgrounds and sex are well-characterized. However, little is known on the impact of telestroke in addressing disparities in acute ischemic stroke care. METHODS: We conducted a retrospective review of acute ischemic stroke patients evaluated over our 17-hospital telestroke network in Texas from 2015-2018. Patients were described as Non-Hispanic White (NHW) male or female, Non-Hispanic Black (NHB) male or female, or Hispanic (HIS) male or female. We compared frequency of tPA and mechanical thrombectomy (MT) utilization, door-to-consultation times, door-to-tPA times, and time-to-transfer for patients who went on to MT evaluation at the hub after having been screened for suspected large vessel occlusion at the spoke. RESULTS: Among 3873 patients (including 1146 NHW male (30%) and 1134 NHW female (29%), 405 NHB male (10%) and 491 NHB female (13%), and 358 HIS male (9%) and 339 HIS female (9%) patients), we did not find any differences in door-to consultation time, door-to-tPA time, time-to-transfer, frequency of tPA administration, or incidence of MT utilization. CONCLUSION: We did not find racial, ethnic, and sex disparities in ischemic stroke care metrics within our telestroke network. In order to fully understand how telestroke alleviates disparities in stroke care, collaboration among networks is needed to formulate a multicenter telestroke database similar to the Get-With-The Guidelines.

Stroke Templates and Trainee Education are Associated With Improved Data Capture in an Academic Hospital.

BACKGROUND: Effective medical record documentation is required to support accurate capture of diagnoses, patient acuity (case mix index [CMI]), and justify resource utilization for reimbursement. Billing code complexity and a lack of formal documentation education in training programs have created a need for academic medical centers to incorporate training for trainees (residents, fellows, and new nurse practitioners). We hypothesized that standardized stroke note templates, trainee education, and feedback from chart audits would improve documentation accuracy. PURPOSE: To improve the accurate/complete capture of expected (E) length of stay (LOS) and CMI by designing/implementing ischemic and hemorrhagic stroke templates containing high-frequency complication and comorbidity diagnoses with the greatest impact on stroke populations, combined with trainee education and chart audits. METHODS: Descriptive statistics were used for outcomes before/after implementation of the templates. Primary outcomes include ELOS and CMI. Wilcoxon rank-sum test or chi-square test was used for group comparison. RESULTS: The post-template group demonstrated a significant improvement in ELOS from 5.84 to 8.27 days (p < .0001). Case mix index increased (1.73-1.75; p < .0001) in the post-template group. CONCLUSIONS: Stroke-specific templates, trainee education, and chart audits were associated with significant improvement in documentation accuracy and an improved business model of stroke care in our hospital.

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.

No Weekend or After-Hours Effect in Acute Ischemic Stroke Patients Treated by Telemedicine.

BACKGROUND: Stroke outcomes have been shown to be worse for patients presenting overnight and on weekends (after-hours) to stroke centers compared with those presenting during business hours (on-hours). Telemedicine (TM) helps provide evaluation and safe management of stroke patients. We compared time metrics and outcomes of stroke patients who were assessed and received intravenous recombinant tissue plasminogen activator (IV-tPA) via TM during after-hours with those during on-hours. METHODS: Analysis of our TM registry from September 2015 to December 2016, identified 424 stroke patients who were assessed via TM and received IV-tPA. We compared baseline characteristics, clinical variables, time metrics, and outcomes between the after-hours (5 pm-7:59 am, weekends) and on-hours (weekdays 8 am-4:59 pm) patients. RESULTS: Of the 424 patients, 268 were managed via TM during after-hours, and 156 during on-hours. Baseline characteristics and clinical variables were similar between the groups. Importantly, there were no differences in all relevant time metrics including door to IV-tPA bolus time. IV-tPA complications (including all intracerebral hemorrhage (ICH), any systemic bleeding, and angioedema), discharge disposition, and 90-day modified Rankin Scale were also similar in the groups. CONCLUSIONS: There was no difference in IV-tPA treatment times, acute stroke evaluation times, or mortality between the patients treated after-hours versus on-hours. Unlike in-person neurology coverage at many centers, the coverage provided by TM does not differ depending on the hour or day. Access to stroke specialists 24/7 via TM can ensure dependable and timely clinical care for acute stroke patients regardless of the time of day or day of the week.

Non-Vitamin K Oral Anticoagulants (NOACs) and Their Reversal.

PURPOSE OF REVIEW: An 80-year-old man presents with an acute right hemiparesis and National Institutes of Health Stroke Scale (NIHSS) of 25, 14 h after taking dabigatran. Activated partial thromboplastin time (aPTT) is 42.8 s. Arteriogram demonstrates left internal carotid artery thrombosis. What is the appropriate management of this patient with acute ischemic stroke while on a NOAC? RECENT FINDINGS: Idarucizumab is a reversal agent approved for dabigatran, and two more reversal agents, andexanet alfa and aripazine, are currently in development for NOACs. In this article, we review currently available NOACs, their laboratory monitoring, and reversal agents.
