<h4>Background and purpose</h4>The decision to administer tPA to acute stroke patients is frequently made by stroke attendings or fellows, but placing residents in this position may make tPA delivery more efficient.<h4>Methods</h4>Beginning in 2004, we instituted a resident-based acute stroke protocol placing neurology residents in decision-making roles. Time-intervals, symptomatic hemorrhage rate, and discharge locations were prospectively collected and compared between two epochs, before and a ...[more]

Project description:BackgroundWe implemented a multi-disciplinary process improvement intervention at our Comprehensive Stroke Center with speech/language pathologists to expedite oral medication delivery in stroke patients. Following a failed nursing dysphagia screen, trained neurology physicians screened dysphagia further to approve use of oral medications. We analyzed the safety and efficacy of this intervention.MethodsWe analyzed retrospectively collected data for hospital course, timing of first screen, first oral medication use, and complications (e.g., aspiration pneumonia) in consecutive ischemic stroke patients (9/2019-07/2021). Patients were included if they passed a dysphagia assessment by physicians (Ph), nurses (RN), or speech/language pathologists (SLP). Arrival-to-dysphagia screen and arrival-to-antithrombotic were assessed using restricted mean survival time (RMST).ResultsOf the 789 included patients, 673 were passed by RN, 104 by SLP, and 12 by Ph. Compared to patients passed by SLP, those passed by Ph were younger and had less severe deficits (P < .01 for both). Patients were screened more quickly by Ph than RN or SLP (median 38 vs 182 vs 1330-min post-arrival, P = .0001; 299-min RMST difference vs RN [95%CI 22-575, P = .03]; 470-min RMST difference vs SLP [95%CI 175-765, P = .002]). This translated to faster oral antithrombotic use for Ph-passed patients (138-min RMST difference vs RN [95%CI 59-216]; 332-min RMST difference vs SLP [95%CI 253-411]). No patients passed by Ph experienced aspiration pneumonia (0%).ConclusionsWe safely conducted a physician-driven dysphagia screening paradigm which led to faster oral antithrombotic delivery without signal of patient harm. Physician availability to complete dysphagia screens in acute stroke patients was a limitation.

Project description:Background and purposeMechanical thrombectomy has dramatically increased patient volumes transferred to comprehensive stroke centers (CSCs), resulting in transfer denials for patients who need higher level of care only available at a CSC. We hypothesized that a distributive stroke network (DSN), triaging low severity acute stroke patients to a primary stroke center (PSC) upon initial telestroke consultation, would safely reduce transfer denials, thereby providing additional volume to treat severe strokes at a CSC.MethodsIn 2017, a DSN was implemented, in which mild stroke patients were centrally triaged, via telestroke consultation, to a PSC based upon a simple clinical severity algorithm, while higher acuity/severity strokes were triaged to the CSC. In an observational cohort study, data on acute ischemic stroke patients presenting to regional community hospitals were collected pre- versus post-DSN implementation. Safety outcomes and rate of CSC transfer denials were compared pre-DSN versus post-DSN.ResultsThe pre-DSN cohort (n=150), triaged to the CSC, had a similar rate of symptomatic intracerebral hemorrhage and discharge location compared with the post-DSN cohort (n=150), triaged to the PSC. Time to stroke unit admission was faster post-DSN (2 hours 40 minutes) versus pre-DSN (3 hours 29 minutes; P<0.001). Transfer denials were reduced post-DSN (3.8%) versus pre-DSN (1.8%; P=0.02), despite an increase in telestroke consultation volume over the same period (median, 3 calls per day pre-DSN versus 5 calls per day post-DSN; P=0.001). No patients who were triaged to the PSC required subsequent transfer to the CSC.ConclusionsA DSN, triaging mild ischemic stroke patients from community hospitals to a PSC, safely reduced transfer denials to the CSC, allowing greater capacity at the CSC to treat higher acuity stroke patients.

Project description:IntroductionPediatric stroke is among the top 10 causes of death in pediatrics. Rapid recognition and treatment can improve outcomes in select patients, as evidenced by recent retrospective studies in pediatric thrombectomy. We established a collaborative protocol involving the vascular neurology and pediatric neurology division in our institution to rapidly diagnose and treat pediatric suspected stroke. We also prospectively collected data to attempt to identify predictors of acute stroke in pediatric patients.MethodsIRB approval was obtained to prospectively collect clinical data on pediatric code stroke activations based on timing metrics in resident-physician note templates. The protocol emphasized magnetic resonance imaging over computed tomography imaging when possible. We analyzed performance of the system with descriptive statistics. We then performed a Bayesian statistical analysis to search for predictors of pediatric stroke.ResultsThere were 40 pediatric code strokes over the 2.5-year study period with a median age of 10.8 years old. 12 (30%) of patients had stroke, and 28 (70%) of code stroke patients were diagnosed with a stroke mimic. Median time from code stroke activation to completion of imaging confirming or ruling out stroke was 1 h. In the Bayesian analysis, altered mental status, hemiparesis, and vasculopathy history were associated with increased odds of stroke, though credible intervals were wide due to the small sample size.ConclusionA trainee developed and initiated pediatric acute stroke protocol quickly implemented a hospital wide change in management that led to rapid diagnosis and triage of pediatric stroke and suspected stroke. No additional personnel or resources were needed for this change, and we encourage other hospitals and emergency departments to implement similar systems. Additionally, hemiparesis and altered mental status were predictors of stroke for pediatric acute stroke activation in our Bayesian statistical analysis. However credible intervals were wide due to the small sample size. Further multicenter data collection could more definitively analyze predictors of stroke, as well as the help in the creation of diagnostic tools for clinicians in the emergency setting.

Project description:Advanced neuroimaging is one of the most important means that we have in the attempt to overcome time constraints and expand the use of intravenous thrombolysis (IVT). We assessed whether, and how, the prior use of advanced neuroimaging (AN), and more specifically CT/MR perfusion post-processed with RAPID software, regardless of time from symptoms onset, affected the outcomes of acute ischemic stroke (AIS) patients who received IVT. Methods. We retrospectively evaluated consecutive AIS patients who received intravenous thrombolysis monotherapy (without endovascular reperfusion) during a six-year period. The study population was divided into two groups according to the neuroimaging protocol used prior to IVT administration in AIS patients (AN+ vs. AN-). Safety outcomes included any intracranial hemorrhage (ICH) and 3-month mortality. Effectiveness outcomes included door-to-needle time, neurological status (NIHSS-score) on discharge, and functional status at three months assessed by the modified Rankin Scale (mRS). Results. The rate of IVT monotherapy increased from ten patients per year (n = 29) in the AN- to fifteen patients per year (n = 47) in the AN+ group. Although the onset-to-treatment time was longer in the AN+ cohort, the two groups did not differ in door-to-needle time, discharge NIHSS-score, symptomatic ICH, any ICH, 3-month favorable functional outcome (mRS-scores of 0-1), 3-month functional independence (mRS-scores of 0-2), distribution of 3-month mRS-scores, or 3-month mortality. Conclusion. Our pilot observational study showed that the incorporation of advanced neuroimaging in the acute stroke chain pathway in AIS patients increases the yield of IVT administration without affecting the effectiveness and safety of the treatment.

Project description:BACKGROUND:Despite evidence from clinical trials that intravenous (IV) thrombolysis is a cost-effective treatment for selected acute ischaemic stroke patients, there remain large variations in the rate of IV thrombolysis delivery between stroke services. This study is evaluating whether an enhanced care pathway delivered by paramedics (the Paramedic Acute Stroke Treatment Assessment (PASTA)) could increase the number of patients who receive IV thrombolysis treatment. METHODS:Study design: Cluster randomised trial with economic analysis and parallel process evaluation. SETTING:National Health Service ambulance services, emergency departments and hyper-acute stroke units within three geographical regions of England and Wales. Randomisation: Ambulance stations within each region are the units of randomisation. According to station allocation, paramedics based at a station deliver the PASTA pathway (intervention) or continue with standard stroke care (control). Study intervention: The PASTA pathway includes structured pre-hospital information collection, prompted pre-notification, structured handover of information in hospital and assistance with simple tasks during the initial hospital assessment. Study-trained intervention group paramedics deliver this pathway to adults within 4 h of suspected stroke onset. Study control: Standard stroke care according to national and local guidelines for the pre-hospital and hospital assessment of suspected stroke. PARTICIPANTS:Participants enrolled in the study are adults with confirmed stroke who were assessed by a study paramedic within 4 h of symptom onset. PRIMARY OUTCOME:Proportion of participants receiving IV thrombolysis. SAMPLE SIZE:1297 participants provide 90% power to detect a 10% difference in the proportion of patients receiving IV thrombolysis. DISCUSSION:The results from this trial will determine whether an enhanced care pathway delivered by paramedics can increase thrombolysis delivery rates. TRIAL REGISTRATION:ISRCTN registry, ISRCTN12418919 . Registered on 5 November 2015.

Project description:IntroductionThe knowledge of clinicians regarding blood transfusion services may impact patient care and transfusion outcome. The wide variation in transfusion practices among clinicians leads to inappropriate blood product usage and jeopardizes patient safety. Hence, this survey study aimed to assess knowledge, attitude and practice among the residents and interns of safe blood transfusion.MethodsThe online survey was based on self-administered questionnaires of three sections: 1. Demography; 2. Knowledge, and; 3. Attitude and Practice. One point was assigned for the correct response of each question in every section. The knowledge score was further categorized into three categories, depending on the points obtained. The participants were also divided into four groups, depending on their experience. The Kruskal-Wallis test was applied to determine the difference of knowledge and practice scores in three designated groups of residents and interns. A p-value of less than 0.05 was considered to be significant.ResultA total of 247 residents and interns participated in this study. Thirteen participants had an incomplete response. Out of 234 participants, Senior Residents (SR), Junior Residents (JR), and interns were 70, 96 and 68 participants, respectively. The knowledge scores of interns were significantly low, as compared to SRs and JRs. Practice scores of interns were also significantly low, compared to the JRs. However, most of the residents and interns (85%) were aware of the pre-transfusion testing.ConclusionTherefore, the mandatory incorporation of the transfusion medicine subject in the undergraduate curriculum can help the young budding doctors to better implement the patient blood management.

Project description:Background and purposeIntravenous thrombolysis and mechanical thrombectomy predominantly using stent retrievers have been shown to effectively restore cerebral blood flow and improve functional outcome in patients with acute ischemic stroke. We sought to determine the safety and feasibility of mechanical thrombectomy using the new ERIC retrieval device.Materials and methodsWe identified 36 consecutive patients from our Stroke Center registry with acute ischemic stroke who were treated with the new ERIC retriever from September 2013 to December 2014. Patients with ischemic stroke meeting the following criteria were eligible: onset-to-treatment time of ≤4.5 hours or wake-up stroke (n = 10) with relevant CT perfusion mismatch, NIHSS score of ≥4, and proof of large-vessel occlusion in the anterior circulation on CT angiography. We assessed the baseline characteristics including age, sex, comorbidities, stroke severity, site of vessel occlusion, presence of tissue at risk, and treatment-related parameters such as onset-to-treatment time, recanalization grade, and outcome.ResultsThe mean age was 70 ± 13 years, and the median NIHSS score on admission was 18 (interquartile range, 10-20). Seventeen of 36 patients were on platelet inhibitors or anticoagulants before endovascular treatment (47.2%); 20 patients received intravenous thrombolysis (55.5%). The ERIC was used as the sole retriever in 28 patients (77.8%) and as a rescue device in 8. Excellent recanalization was achieved in 30/36 patients (83.3%) with TICI 3 in 19/36 and 2b in 11/36, respectively. Median procedural time in these patients was 90 minutes (interquartile range, 58-133 minutes). No intraprocedural complications occurred.ConclusionsIn this observational study, the new ERIC retrieval device was technically feasible, safe, and effective in acute ischemic stroke with large-vessel occlusion.

Project description:BackgroundLiterature on the effectiveness of simulation-based medical education programs for caring for acute ischemic stroke (AIS) patients is limited.ObjectiveTo improve coordination and door-to-needle (DTN) time for AIS care, we implemented a stroke simulation training program for neurology residents and nursing staff in a comprehensive stroke center.MethodsAcute stroke simulation training was implemented for first-year neurology residents in July 2011. Simulations were standardized using trained live actors, who portrayed stroke vignettes in the presence of a board-certified vascular neurologist. A debriefing of each resident's performance followed the training. The hospital stroke registry was also used for retrospective analysis. The study population was defined as all patients treated with intravenous tissue plasminogen activator for AIS between October 2008 and September 2014.ResultsWe identified 448 patients meeting inclusion criteria. Simulation training independently predicted reduction in DTN time by 9.64 minutes (95% confidence interval [CI] -15.28 to -4.01, P = .001) after controlling for age, night/day shift, work week versus weekend, and blood pressure at presentation (> 185/110). Systolic blood pressure higher than 185 was associated with a 14.28-minute increase in DTN time (95% CI 3.36-25.19, P = .011). Other covariates were not associated with any significant change in DTN time.ConclusionsIntegration of simulation based-medical education for AIS was associated with a 9.64-minute reduction in DTN time.

Project description:For some stroke patients and caregivers, navigating the transition between hospital discharge and returning home is associated with substantial psychosocial and health-related challenges. Currently, no evidence-based standard of care exists that addresses the concerns of stroke patients and caregivers during the transition period. Objectives of the Michigan Stroke Transitions Trial (MISTT) are to test the impact of a social worker home-based case management program, as well as an online information and support resource, on patient and caregiver outcomes after returning home.The Michigan Stroke Transitions Trial is a randomized, pragmatic, open (un-blinded), 3-group parallel designed superiority trial conducted in 3 Michigan hospitals. Eligible participants are adult acute stroke patients discharged home directly or within 4 weeks of being discharged to a rehabilitation facility. The patient's primary caregiver is also invited to participate. Patients are randomized on the day they return home using a randomized block design. Consented patients discharged to a rehabilitation facility who do not go home within 4 weeks are dropped from the study. The 2 study interventions begin within a week of returning home and conclude 3 months later. The 3-group design compares usual care to either a home-based social worker stroke case management (SWSCM) program, or a combination of the SWSCM program plus access to an online information and support resource (MISTT website). Outcomes data are collected at 7-days and 90-days by trained telephone interviewers. Primary patient outcomes include the PROMIS global 10 score (a generic Quality of Life scale), and the Patient Activation Measure (PAM). Caregiver outcomes include the Bakas Caregiving Outcomes Scale. Final analysis will be based on 214 randomized acute stroke patients. To accommodate subjects excluded due to prolonged rehabilitation stays, as well as those lost-to-follow-up, up to 315 patients will be consented.The MISTT study will determine if a home-based case management program designed around the needs and preferences of stroke patients and caregivers, alone or in combination with a patient-centered online information and support resource can improve stroke survivor and caregiver outcomes 3 months after returning home.ClinicalTrials.gov: NCT02653170 (Protocol ID: 135457).
