Stroke | March 11, 2021 | Volume: 52 | Issue: Suppl_1 | Pages: No page available

10.1161/str.52.suppl_1.p564

Background: Data from the CDC show that approximately one-quarter of adults have elevated triglyceride (TG) levels. Recent trials have demonstrated that pharmacologic treatment of high TG levels, in patients already on statin therapy, reduces the rate of major vascular events such as myocardial infarction and stroke (REDUCE-IT trial). We sought to assess how often patients with asymptomatic carotid stenosis (CS) have elevated TG levels and factors associated with high TG values. Methods: Patients enrolled in the Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial (CREST 2) were analyzed. Baseline lipid profiles were evaluated to determine high TG treatment eligibility as per the REDUCE-IT trial. We also evaluated baseline use of pharmacologic treatment for high TG levels. Demographic factors and baseline medical conditions were studied in relation to high (>150 mg/dl) TG values. Chi square and t tests were used to assess baseline factors and abnormal TG values. Results: As of August 10, 2020, 1655 of 1689 randomized patients (mean age 69.7 years, 61% men) had baseline lipid profiles suitable for analysis. Treatment eligibility according to REDUCE-IT (LDL 41-100 mg/dl, TG>150 mg/dl) was present in 21% (345) of subjects. In these patients, the median TG value was 205 (IQR 93) mg/dl. Fibrate medications were used at baseline in 4.5% of patients. Analysis of demographic and medical history factors and TG values greater than 150 mg/dl is found in the Table. There was significant positive correlation between baseline hemoglobin A1C and triglyceride values (p<0.0001) Conclusions: One in five patients in CREST 2 has TG values that potentially justify pharmacologic treatment. Elevated TG levels are most correlated with diabetes, hypertension, obesity, decreased physical activity, and heart disease. Clinicians should investigate treatment of elevated TG levels as a component of intensive medical therapy for stroke prevention.
Abstract P135: Telestroke Mimic Score: Validation in the Mayo Clinic Population

Stroke | March 11, 2021 | Volume: 52 | Issue: Suppl_1 | Pages: No page available

Introduction: Telestroke consultations enable hospital providers to administer IV alteplase to patients who would otherwise not receive it due to lack of an in-house neurologist. However, up to 30% of acute stroke evaluations are deemed stroke mimics. These present a challenge with the limitations of a virtual neurological exam. The use of IV alteplase in these patients is not risk-free. With the rise in cost of IV alteplase, there are ethical and practical incentives to avoid administering alteplase to a stroke-mimic. Recently a retrospective analysis validated a TeleStroke Mimic Score (TM-Score) to help detect stroke mimics. We retrospectively applied this tool to our Stroke Telemedicine for Arizona Rural Residents (STARR) telestroke database to provide external validation in an independent study population. Methods: We analyzed 339 patients in our STARR database for validation of the TM-Score, which was applied in retrospect to determine if it predicts stroke-mimic given data available during each patient’s telestroke consult. We assessed its performance with a receiver-operating characteristic (ROC) curve. Patient characteristics are displayed in table form. A scatter plot of the data shows the relationship between the TM-Score and the likelihood of having a stroke mimic, compared to the nomogram in the original study. Results: When the TM-Score was applied to our validation cohort, the area under the ROC curve was 0.78, larger than that of the derivation cohort in the original study (0.75). Further analysis suggests that a TM-Score greater than 25 or less than 10 would provide a greater degree of confidence that the patient is presenting with stroke or stroke mimic, respectively. In our cohort, additional variables were significantly different between stroke and stroke mimic populations, including history of sleep apnea or diabetes. Conclusion: We found that the TM-Score is validated when applied to Mayo Clinic’s STARR telestroke population. Validation of this tool helps establish the utility and broader generalizability of this equation. Effective use of this tool can help reduce risk to the patient and has additional cost-saving implications. This should help ensure that the patient receives the appropriate targeted workup and treatment.

ABSTRACT BACKGROUND There is limited data regarding financial trends for procedural reimbursement in stroke care. A comprehensive understanding of such trends is important as continued progress is made to advance agreeable reimbursement models in the care of stroke patients. OBJECTIVE To evaluate monetary trends in Medicare reimbursement rates for commonly utilized procedures in stroke care from 2000 to 2019. METHODS The Centers for Medicare & Medicaid Services was queried for the included Current Procedural Terminology (CPT) codes and reimbursement data were extracted. The CPT codes compiled were the most commonly performed procedures for stroke-related International Classification of Diseases (ICD)-10 codes at our institution (I60-I63). Additionally, data were collected for alteplase and telestroke codes. The rate of change between procedures was compared utilizing an unpaired Student's t -test. All monetary data were adjusted for inflation to 2019 US dollars utilizing the US Consumer Price Index. RESULTS After adjusting for inflation, the average reimbursement for stroke (ICD I60-I63) procedures decreased by 11.2% from 2000 to 2019 (average of −0.43% per year). The adjusted reimbursement rate for included telestroke codes decreased by 12.1% from 2010 to 2019 (average of −1.4% per year). From 2005 to 2019, the reimbursement for alteplase rose by 163.98% (average of +7.3% per year). CONCLUSION When adjusted for inflation, Medicare reimbursement for common stroke procedures has decreased from 2000 to 2019. In contrast, reimbursement for alteplase has increased markedly. It is important to be aware of these trends in order to contextualize healthcare economic analyses and inform discussions.

Background:Concussion affects almost 4 million individuals annually. There are many sideline screening tools available to assist in the detection of sports-related concussion. The King-Devick (K-D) test in association with Mayo Clinic utilizes rapid number naming to test saccadic eye movements in order to screen for concussion. An ideal screening tool for concussion would correctly identify all athletes with active concussion. The accuracy of K-D testing compared with other sideline screening tools is undetermined.Objective:To critically assess current evidence regarding the utility of K-D testing as a sideline screening tool for acute concussion and compare K-D testing to other sideline concussion assessments.Methods:The objective was addressed through the development of a critically appraised topic that included a clinical scenario, structured question, literature search strategy, critical appraisal, assessment of results, evidence summary, commentary, and bottom-line conclusions. Participants included consultant and resident neurologists, a medical librarian, clinical epidemiologists, and content experts in the field of concussion neurology and neuro-ophthalmology.Results:A recent meta-analysis was selected for critical appraisal. Cohorts analyzing athletes with sports-related concussion were selected, and utilized K-D testing as the main baseline and sideline assessment of concussion. K-D testing was found to have a high sensitivity and specificity for detecting concussion when there was worsening from baseline.Conclusion:K-D testing has high sensitivity and specificity for detecting sideline concussion. Compared with other sideline screening tools that do not include vision testing, it has greater accuracy. Screening for concussion is optimized when multiple testing modalities are used in conjunction.

Importance: A postoperative video telemedicine follow-up program was introduced by the Mayo Clinic. An attempt was made to understand the potential cost savings to patients before contemplating full-scale expansion across all potentially eligible surgical patients and practices. Objective: The primary purpose was to estimate potential cost savings to patients with video telemedicine follow-up to home compared with face-to-face follow-up in a standard clinic setting. Design: The research was designed collaboratively by the Center for Connected Care and the surgical practice to address the question of estimated cost savings of postoperative video telemedicine visits. The intervention arm is the postoperative video telemedicine follow-up visit to home setting and the comparator is the face-to-face visit at Mayo Clinic. Setting: Large, integrated, academic multispecialty practice supporting patient care delivery, research, and education. Participants: The population under study comprised routine uncomplicated postoperative patients who underwent video telemedicine or face-to-face follow-up visits that fell within the 90-day global period across multiple (general, neurosurgery, plastic, thoracic, transplant, and urology) surgical specialties. Main Outcome(s) and Measure(s): Economic outcomes were cost of travel, accommodations, meals, and missed work. Additional outcomes included time expenditure and patient satisfaction. Cost/benefit analysis unit was US dollars (USD). All costs were inflated to 2018 USD, using the Gross Domestic Product Implicit price deflator. Results: Patients who utilized video telemedicine rather than face-to-face clinic visit for postoperative follow-up were estimated to save $888 per visit on average. More specifically, patients residing more than 1,635 miles round trip from clinic saved an estimated $1,501 per visit and patients not needing accommodation still saved an estimated $256 per visit. Patient satisfaction over video telemedicine postoperative follow-up visits remained high over the 6-year period of study. Conclusions and Relevance: The use of video telemedicine for routine uncomplicated postoperative follow-up visits to replace face-to-face follow-up visits has the potential to be financially advantageous for patients. Key points Question: For postoperative patients, what are the health economic outcomes associated with video telemedicine follow-up to home compared with face-to-face follow-up in a standard clinic setting? Findings: Video telemedicine offers a cost benefit for patients through avoidance of travel costs and missed work. Meaning: For uncomplicated routine postoperative follow-up visits, video telemedicine is a less costly alternative for most patients.

Introduction Globally, the use of telestroke programmes for acute care is expanding. Currently, a standardised set of variables for enabling reliable international comparisons of telestroke programmes does not exist. The aim of the study was to establish a consensus-based, minimum dataset for acute telestroke to enable the reliable comparison of programmes, clinical management and patient outcomes. Methods An initial scoping review of variables was conducted, supplemented by reaching out to colleagues leading some of these programmes in different countries. An international expert panel of clinicians, researchers and managers ( n = 20) from the Australasia Pacific region, USA, UK and Europe was convened. A modified-Delphi technique was used to achieve consensus via online questionnaires, teleconferences and email. Results Overall, 533 variables were initially identified and harmonised into 159 variables for the expert panel to review. The final dataset included 110 variables covering three themes (service configuration, consultations, patient information) and 12 categories: (1) details about telestroke network/programme ( n = 12), (2) details about initiating hospital ( n = 10), (3) telestroke consultation ( n = 17), (4) patient characteristics ( n = 7), (5) presentation to hospital ( n = 5), (6) general clinical care within first 24 hours ( n = 10), (7) thrombolysis treatment ( n = 10), (8) endovascular treatment ( n = 13), (9) neurosurgery treatment ( n = 8), (10) processes of care beyond 24 hours ( n = 7), (11) discharge information ( n = 5), (12) post-discharge and follow-up data ( n = 6). Discussion The acute telestroke minimum dataset provides a recommended set of variables to systematically evaluate acute telestroke programmes in different countries. Adoption is recommended for new and existing services.

Background: With increasing demand for neurologists, nontraditional health care delivery mechanisms have been developed to leverage this limited resource. Introduction: Telemedicine has emerged as an effective digital solution. Over the past three decades, telemedicine use has steadily grown; however, neurologists often learn on the job, rather than as part of their medical training. The current literature regarding telestroke training during neurology training is sparse, focusing on cerebrovascular fellowship curricula. We sought to enhance telestroke training in our neurology residency by incorporating real-life application. Materials and Methods: We implemented a formal educational model for neurology residents to use telemedicine for remote acquisition of the National Institutes of Health Stroke Scale (NIHSS) for patients with suspected acute ischemic stroke (AIS) before arrival at our comprehensive stroke center. This three-phase educational model involved multidisciplinary classroom didactics, simulation exercises, and real-world experience. Training and feedback were provided by neurologists experienced in telemedicine. Results: All residents completed formal training in telemedicine prehospital NIHSS acquisition and had the opportunity to participate in additional simulation exercises. Currently, residents are gaining additional experience by performing prehospital NIHSS acquisition for patients in whom AIS is suspected. Our preliminary data indicate that resident video encounters average 10.6 min in duration, thus saving time once patients arrive at our hospital. Discussion: To our knowledge, this is the first report of a telestroke-integrated neurology residency program in a comprehensive stroke center resulting in shortened time to treatment in patients with suspected AIS. Conclusions: We present a model that can be adopted by other neurology residency programs as it provides real-world telemedicine training critical to future neurologists.
