Introduction: Treatment time has gained sufficient popularity because it is now well-known that “Time is Brain”. Treatment rates, however, lag behind in importance even though more lives can be saved by treating more often. Our TJC Comprehensive Stroke Center has a nurse-led stroke alert process that focuses on multiple, rapid, parallel steps to reduce DTN for IV alteplase. The Baptist Emergency Stroke Team (BEST) responders are highly-trained and skilled nurses that assess, coordinate, and initiate processes to ensure the best times. We identified that our treatment rate was lower than the national rate for certified CSCs, so the BEST responders used a stepwise process to develop their own interventions to improve rates. Methods: First, the BEST responders started tracking our monthly rate. Next, they set a rate goal, and then brainstormed how to influence treatment decision-making. The BEST team initiated a monthly PI meeting that focused on the importance of treating disability rather than an NIHSS score. Then the team scripted and rehearsed critical conversations to have providers that advocated specifically for treating disability. The team adopted the motto, “Treat Disability, Not Numbers”. Results Conclusions: Our CSC observed a small decrease in median DTN but double the treatment rate after the BEST responder intervention. In comparison, these statistics did not change at the national CSC level. The sICH rate was reduced from Period A to C, meaning that increased treatment rate did not lead to increased hemorrhagic rate. Nursing initiatives can have a substantial positive effect on increasing the number of patients treated with IV alteplase for acute ischemic stroke.

Background and Purpose: The hypoperfusion intensity ratio (HIR) is a perfusion-weighted imaging parameter defined as the ratio of Tmax>10 seconds : Tmax>6 seconds volume and is believed to be reflective of collateral strength and consequently influence infarct growth. We sought to assess the utility of the HIR in predicting infarct growth in patients undergoing thrombectomy at a comprehensive stroke center (CSC). Methods: Consecutive acute ischemic stroke patients transferred to our CSC from 09/2010-11/2018 were identified and included if the following criteria were met: 1)computed tomography perfusion (CTP) imaging enabling assessment of baseline ischemic core volume and HIR 2) follow-up neuroimaging for assessment of final infarct volumes and 3)modified Thrombolysis In Cerebral Infarction scale (mTICI) 2c status or greater post-thrombectomy. Infarct growth rate (IGR) was calculated as the difference between infarct volume on follow-up imaging and the acute DWI lesion volume, divided by time from CTP to reperfusion in hours. Results: 461 patients (median age, 64 [55-75] years, median baseline NIHSS, 16 [12-21]) were eligible for this analysis. HIR poorly correlated with IGR (Spearman’s rho=0.001, p=0.89). An HIR cut-off of 0.5 was not able to discriminate ‘fast progressors’ (IGR>5 mL/hr) (AUC 0.42, sensitivity 40%, specificity 51%), or IGR at thresholds of either 2.5 or 10 mL/hr (AUC 0.44 and 0.49 respectively, with 95% confidence intervals [0.35-0.52] and [0.41-0.57], respectively). Similarly, an HIR of 0.5 only weakly distinguished ‘fast progression’ in patients reperfused beyond 120 min from imaging and patients with early CTP (last known well to CTP<6 hrs) (AUC 0.59, sensitivity 43%, specificity 68% and AUC 0.50, sensitivity 45%, specificity 55%). On multiple regression analysis, HIR was not predictive of infarct growth (regression equation=18.09+8.48x, F=2.46, p=0.11, R 2 =0.13) but was predictive of ‘fast progression’ (OR 0.22, 95% CI [0.09-0.60], p=0.003, pseudo-R 2 =0.16). Conclusions: Though predictive of fast progression, the HIR is a poor discriminator of infarct growth in successfully reperfused thrombectomy patients who undergo perfusion imaging at a CSC, and thus should not be factored into treatment decision-making.

Background: “Drip-and-ship” denotes patients in whom intravenous (IV) recombinant tissue plasminogen activator (rt-PA) is initiated at the emergency department (ED) of a community hospital, followed by transfer within 24 hours to a comprehensive stroke center. Although drip-and-ship paradigm has the potential to increase the number of patients who receive IV rt-PA, comparative outcomes have not been assessed at a population based level. Methods: State-wide estimates of thrombolysis, associated in-hospital outcomes and mortality were obtained from 2008-2009 Minnesota Hospital Association (MHA) data. Patient numbers and frequency distributions were calculated for state-wide sample of patients hospitalized with a primary diagnosis of ischemic stroke. Patients outcomes were analyzed after stratification into patients treated with IV rt-PA through primary ED arrival or drip-and-ship paradigm. Results: Of the 21,024 admissions, 602 (2.86%) received IV rt-PA either through primary ED arrival (n=473) or drip-and-ship paradigm (n=129). The rates of secondary intracerebral or subarachnoid hemorrhage were higher in patients treated with IV rt-PA through primary ED arrival compared with those treated with drip-and-ship paradigm (8.5% versus 3.1, p=0.038). The in-hospital mortality rate was similar among ischemic stroke patients receiving IV rt-PA through primary ED arrival or drip-and-ship paradigm (5.9% versus 7.0%). The mean hospital charges were $65,669 for primary ED arrival and $47,850 for drip-and-ship treated patients (p<0.001). Conclusions: The results of drip-and-ship paradigm compare favorably with IV rt-PA treatment through primary ED arrival in this state-wide study.

Introduction. Many reports have described a decrease in the numbers of patients seeking medical attention for typical emergencies during the COVID-19 pandemic. These reports primarily relate to urban areas with widespread community transmission. The impact of COVID-19 on nonurban areas with minimal community transmission is less well understood. Methods. Using a prospectively maintained prehospital quality improvement database, we reviewed our hospital EMS transports with a diagnosis of stroke from January to April 2019 (baseline) and January to April 2020 (pandemic). We compared the volume of patients, transport/presentation times, severity of presenting symptoms, and final diagnosis. Results. In January, February, March, and April 2019, 10, 11, 17, and 19 patients, respectively, were transported in comparison to 19, 14, 10, and 8 during the same months in 2020. From January through April 2019, there was a 53% increase in transports, compared to a 42% decrease during the same months in 2020, constituting significantly different trend-line slopes (3.30; 95% CI 0.48–6.12 versus -3.70; 95% CI -5.76–-1.64, p = 0.001 ). Patient demographics, comorbidities, and symptom severity were mostly similar over the two time periods, and the number of patients with a final diagnosis of stroke was also similar. However, the median interval from EMS dispatch to ED arrival for patients with a final diagnosis of stroke was significantly longer in January to April 2020 ( 50 ± 11.7   min ) compared to the same time period in 2019 ( 42 ± 8.2   min , p = 0.01 ). Discussion/Conclusion. Our data indicate a decrease in patient transport volumes and longer intervals to EMS activation for suspected stroke care. These results suggest that even in a nonurban location without widespread community transmission, patients may be delaying or avoiding care for severe illnesses such as stroke. Clinicians and public health officials should not ignore the potential impact of pandemic-like illnesses even in areas of relatively low disease prevalence.

Problem/ Background: Evidence- based practice is the cornerstone in delivery of stroke care to optimize outcomes for patients. Research is the foundation to build and advance clinical practice. As a Comprehensive Stroke Center, we are charged with participating in IRB approved research. In 2016 the SUCCEED trial was stopped here as a result of low enrollment. The stroke nurses were not directly involved in that trial. In 2017, the stroke nurses partnered with our physicians and began the ARAMIS trial. This is a multicenter study of acute stroke patients taking anticoagulation therapy prior to admission and suffering a stroke. We recognized the need for our stroke nurses to collaborate, participate and use their expertise in identifying appropriate research patients for this study. Quality Question: Will tasking Stroke Nurses with identifying patients improve the enrollment of patients in ARAMIS trial? Methods: Stroke nurses attended an ARAMIS training session for physicians. Included in the meeting was review of inclusion/exclusion criteria for patient enrollment. A group e-mail was created for all participating in the study to help identify potential patients. When a patient was discovered an email was sent to the group alerting those responsible for obtaining consent for the study and data collection for the registry. Results: After one trial was ended due to low enrollment, the new ARAMIS trial opened. The stroke team nurses took the lead on identifying patients. Reviewing retrospective data starting in November 2017 until March 2019, 56 patients were enrolled in Aramis. Stroke nurses identified 43 patients (77%), Neurology fellows 10 (18%) and Faculty physicians 3 (5%). Conclusion: When including expert nurses in the patient identification process, the nurse plays a pivotal role in identifying appropriate patient for the MDs to enroll, thus, increasing enrollment in clinical trials. While additional tracking and trending needs to take place as new trails open, this trial makes clear the need for nurse involvement in identifying appropriate patients.

Background: Measuring sICH is an important accountability of Stroke Centers. Since the NINDS rt-PA Study, the sICH definition has changed as knowledge of reperfusion-associated hemorrhagic transformation has grown. We aimed to determine what sICH definition was used by Stroke Centers and how this impacts sICH rates. Methods: Stroke Centers were invited to participate in a survey with the option to complete it via SurveyMonkey TM or by mail. Instructions to adhere to the sICH definition adopted in policies/procedures were provided, and to ask for clarification from Stroke Team members if needed. Data were assembled in SPSS, and analyzed using descriptive statistics and Student t-tests. Results: 229 responses were received representing 84% of U.S. states and the District of Columbia; 31% represented academic medical centers and 69% community hospitals. 64% of respondees were responsible for collecting the stroke quality data that supports certification. Overall tPA treatment rate for the sample was 8.7% + 6.4 (median 7%), with an overall reported sICH rate of 9.5% + 16.4 (median 5%). Official definitions supported sICH for 86% of responding hospitals, however the most common definition (48%) reported was, “any hemorrhage on non-contrast CT or MRI in combination with any clinical deterioration.” Only 17% identified the definition for sICH adopted by TJC for Comprehensive Stroke Center reporting. Among those that adhered to the TJC definition, sICH rates were significantly lower at 3%+2.3 (median 3%; t=4.7; mean difference = 7.7%; p<.0001, 95% CI 4.4-10.95), compared to 10.6%+17.5 (median 6%). Conclusions: Our study documents a significant need for education and inter-rater reliability monitoring of the use of sICH classification after intravenous tPA to ensure accuracy in local quality improvement processes, as well as the validity of data submitted to national stroke registries. Additionally, because sICH associated with reperfusion therapy is a new measure undergoing testing by TJC that could ultimately be tied to future pay-for-performance and public reporting, consensus on its definition as well as reliable sICH classification will be essential to future Stroke Center evaluation.

Introduction: American Stroke Association guidelines recommend pre-hospital stroke code notification via EMS to facilitate prompt treatment decision for acute ischemic stroke (AIS) patients. Despite pre-notification to the stroke team, treatment decisions are often delayed until medical history and last known well times are established. Hypothesis: We hypothesized that screening for IV Alteplase candidacy and obtaining pertinent medical history from a witness or patient during a pre-hospital stroke code activation prior to hospital arrival would decrease door to needle (DTN) times. Methods: A retrospective analysis was conducted on 193 patients presenting to the emergency department (ED) at a Comprehensive Stroke Center (CSC) from February 2016 through July 2016. A process improvement (PI) event was initiated between the CSC and two fire stations with a catchment time of > 10 minutes. For pre-hospital activated stroke codes, the witness or patient was provided the contact card and encouraged to call the centralized number to the Neurologist. Inclusion criteria: All patients presenting to the ED with EMS pre-hospital stroke code activation. Exclusion criteria: Patients presenting to the ED with stroke code initiated after arrival, or medic response events which did not lead to a pre-hospital stroke code activation. Results: After applying criteria, 126 met inclusion and exclusion criteria. A total of 19 patients arrived via the 2 fire stations with pre-hospital stroke code initiations and serve as our intervention group, while 107 patients underwent standard of care. Contact cards were provided to 11 patients (58%) in the intervention group prior to arrival. IV Alteplase was initiated for 3 of 11 patients (27.3%) in the intervention group vs. 19 of 107 patients (17.8%) in the standard of care group. Mean and median DTN times in the intervention group was 36 minutes as compared to a mean of 46.1 minutes and median time of 40 minutes receiving standard of care. Conclusions: Preliminary data suggest that DTN times can be decreased when medical history is obtained prior to hospital arrival to screen for IV Alteplase eligibility. This study warrants further investigation in pre-acquisition of history for pre-hospital stroke code patients.

Background: An estimated two million brain cells die every minute cerebral perfusion is impaired. The best outcomes for acute ischemic strokes are achieved by decreasing the time from emergency department (ED) arrival to thrombolytic therapy. Alteplase, a high risk medication, was dosed and prepared in the pharmacy. This contributed to prolonged door to needle (DTN) times. Purpose: To describe the impact of pharmacist interventions on DTN times in the ED. Methods: All patients who received alteplase for acute ischemic stroke from January 2012 to April 2019 were reviewed. In November 2012, the ED pharmacy program began with a dedicated ED pharmacist for 8 hours a day and expanded to 13 hours a day in September 2014. During those hours alteplase was prepared at bedside in the ED. In November 2015, all pharmacists were trained on the ED code stroke process. Monthly case reviews and DTN times were reported to the stroke coordinators starting January 2017. Alteplase preparation and administration in the computed tomography (CT) room started April 2017. Following comprehensive stroke center certification, routine stroke competency exams were administered to pharmacists in 2018. In 2019, pharmacists started reporting DTN times at neuroscience core team meetings. Results: During this time frame, a total of 407 patients received alteplase. Average DTN times decreased from a baseline of 130.9 minutes to 45.3 minutes. Interventions that resulted in the largest decrease in average DTN times were the expanded ED service hours (34.6 minutes) and pharmacist preparation of alteplase in the CT room (21.9 minutes). Conclusions: Pharmacists directly impacted stroke care in the ED by decreasing DTN times. Presence of a pharmacist in the ED enabled fast and safe delivery of alteplase by ensuring accurate dosing and preparation. Pharmacists also performed rapid medication reconciliation and expedited antihypertensive therapies. In conclusion, having pharmacists as part of the stroke team is a model that could be adopted by hospitals to enhance stroke care.

Background: Various strategies have been implemented to reduce acute stroke treatment times. A unique code process pathway was designed at our hospital specifically to be activated by the stroke team for the purpose of rapidly assembling the Neurointerventional team. Methods: Code Neurointervention (NI), was designed and tested from January 2014 to April 2014 for all the patients who presented with ischemic strokes to our community based, university affiliated comprehensive stroke center. We retrospectively analyzed all patients who had Code NI called from May 1, 2014 to April 30, 2015 and compared them to patients who underwent acute endovascular treatment the prior year (Non Code NI). The following parameters were compared: decision to recanalization and door to recanalization times. Further analysis was done to compare patients presenting during business hours (Monday-Friday 8am-5pm) and off hours using GraphPad QuickCalcs Web site. Results: There were 28 Code NI; 14 were called during work hours and 14 during off hours. The previous year 25 patients underwent acute endovascular intervention; 12 during work hours and 13 during off hours. Mean decision to recanalization time was 106 (Code NI) vs 115 minutes (Non Code NI) (p<0.0.6) during work hours and 154 (Code NI) vs 139 minutes (Non Code NI) (p<0.37) during off hours. Mean door to recanalization time was 169 (Code NI) vs 173 minutes (Non Code NI) (p<0.85) during work hours and 252 (Code NI) vs 243minutes (Non Code NI) (p< 0.75) during off hours. Subset analysis of time parameters for patients in Code NI group showed mean decision to recanalization times of 106 minutes during work hours vs 154 minutes off work hours (p<0.004). Mean door to recanalization times were 169 minutes vs 251 minutes (p<0.0003), respectively. Conclusion: Institution of Code NI significantly improved intervention time parameters during work hours as compared to off hours. Rapid assembly of the neurointervention team, rapid availability of imaging and angiography suite likely contribute to these differences. Further initiatives, such as improving neurointervention staff availability during off hours or cross training other staff can further improve acute intervention time parameters.

Introduction: Endovascular treatment (EVT) is a widely proven method to treat patients diagnosed with intracranial large vessel occlusion. In order to ensure patients safety prior to and during EVT, preprocedural intubation has been adopted in many centers as a means for airway protection and immobilization. However, the correlation between site of vessel occlusion, need for intubation, and outcomes, has not yet been established. Methods: Through the utilization of a prospectively collected database at a comprehensive stroke center between 2012-2020, demographics, co-morbid conditions, intracerebral hemorrhage, mortality rate, and functional independence outcomes were examined. The outcomes and sites of occlusion between patients receiving mechanical thrombectomy (MT) treated while intubated versus those treated under conscious sedation (CS) were compared. Results: Out of 625 patients treated with MT, a total of 218 (34.9%) were treated while intubated (average age 70.3 ± 13.7, 37.2% women), and 407 (65.1%) were treated while under CS (average age 70.3 ± 13.7, 47.7% women); see Table 1 for baseline characteristics and outcomes. A higher number of patients requiring intubation had an occlusion in the basilar versus those only requiring CS. No differences were noted in regard to the proportion of patients receiving intubation or CS when treated for RMCA, LMCA, or internal carotid artery occlusions. Conclusion: Intubation + MT was associated with significantly worsened outcomes in regard to recanalization rates, functional outcome, and mortality. In anterior circulation strokes, intubation in RMCA patients were found to have poorer clinical outcome. Higher rates of intubation were also found to be needed in patients with basilar occlusions. Further research is required to determine whether site of occlusion dictates the need for intubation, and whether intubation allows for favorable outcome between R and LMCA occlusions.
