Background: Risks and benefits of thrombectomy in elderly stroke patients remained unclear. We evaluated outcomes in the elderly who underwent endovascular therapy (EST) in a large integrated healthcare system. Methods: In 2016, our integrated healthcare system launched a new standardized acute telestroke care workflow for all 21 stroke centers. It included immediate evaluation by a stroke neurologist via video, expedited IV alteplase treatment, rapid CT angiographic investigation, and expedited transfer and EST for patients with large vessel occlusion (LVO). From January 2016 through December 2018, our study cohort included adult members who had EST within our care system. We compared patient characteristics, door-to-needle (DTN) times, door-to-groin (DTG) times, inpatient and 90-day mortality between those treated with EST aged <80 to those ≥80 years. Multivariable logistic regression model was used to assess whether being ≥80 years was associated with a higher 90-day mortality adjusting for demographics, co-morbidities, and DTG time. Results: There were 291 acute stroke patients who underwent EST [Table]. The older subgroup had a higher percentage of female and higher rates of atrial fibrillation. They were more likely to arrive by EMS, to have a higher initial NIHSS and to have a faster DTN time. Average DTG times and inpatient mortality rates were not different between groups. The elderly had a higher rate of 90-day mortality. In multivariate model, being elderly was associated with higher 90-day mortality (OR=2.56, 95% CI 1.29-5.09, p=0.007). Conclusions: For those who underwent EST in a large community setting with a standardized approach to acute stroke treatment, being elderly was associated with a higher risk of 90-day mortality. Further data analyses are being carried out with additional co-morbidities, inpatient complications, and 90-day functional outcome to better understand outcomes in older patients undergoing EST.

Background: Prior published studies reported disparities in timely treatment with tPA for stroke patients who were older, African American or female. In 2015, Kaiser Permanente Northern California (KPNC) redesigned its acute stroke care work flow for the entire region, which included immediate evaluation by a stroke neurologist via video, an expedited IV tPA treatment program, rapid CT angiographic investigation, and expedited transfer of appropriate patients with large vessel occlusion (LVO) for endovascular stroke treatment (EST). We sought to evaluate whether disparities exist in acute stroke treatment within the redesigned process. Methods: KPNC is an integrated health care system with 21 certified stroke centers serving 3.9+ millions members. All centers implemented the new program by January 2016. Using clinical data from 1/1/16 to 7/10/16, we evaluated the frequency of IV tPA administration by gender, race, and age groups after implementation of the new process. We performed multivariate analysis with age, gender, race-ethnicity, Kaiser membership, mode of ED arrival (by ambulance vs. private transportation) to assess for any disparities in achieving DTN time. Results: Post implementation, we found no significant differences in the rates of IV t-pa administration in eligible patients based on race, gender, age category (<40 years, 40-64, 65-79, ≥80), Kaiser membership, or mode of ED arrival. In multivariate analysis for factors influencing DTN time, no differences were seen for DTN time <60 minutes. Age (OR=1.02, 95% CI 1.00-1.03, p=0.03) and arrival by ambulance (OR=5.01, 95% CI 3.01-8.60, p<0.001) were associated with a faster DTN time of <30 minutes. Conclusions: Thus far, we have found no disparities in the use of IV tPA or DTN time for a large integrated healthcare system after implementation of the Stroke EXPRESS program. A consistent standardized approach to acute stroke care may help to reduce disparities on the basis of race, gender, age, or even membership in healthcare system.

Background: Published data suggest that treating qualified acute strokes within the extended window (EW) or 6-24 hours of last seen normal with endovascular therapy (EST) is associated with better 90-day outcome. In a real-world multi-ethnic practice setting, we assessed our experience in triaging and treating patients in the EW. Methods: In 2016, our system of care launched a telestroke program for 19 primary and 2 comprehensive stroke centers to include immediate video evaluation by a stroke neurologist. In 2018, screening in the EW began. If the patient met clinical criteria (baseline independence and initial NIHSS ≥ 6), neuroimaging was performed to assess for a large vessel occlusion (LVO). Referral for EST was made for patients with an LVO and appropriate CT perfusion criteria. Our study included all health plan members presenting within the EW in 2019. Assessment included demographics, NIHSS, neuroimaging data, LVO, discharge outcomes, 90-day mRS and mortality with 95% confidence interval. Results: In 2019, there were 5349 suspected strokes (1255 EW) evaluated by teleneurologists; 2130 (39.8%) patients were appropriate for acute stroke imaging workup. Of 2130, final study cohort included 388 (18.2%) EW patients who met clinical criteria and underwent neuroimaging workup, and 117 of these patients (30.2%) had an LVO. There were 57 (14.7%) meeting CT perfusion criteria and referred for EST. Compared to 331 who were not referred for EST, the 57 patients were older and more likely to have atrial fibrillation, higher NIHSS, and to be discharged to a short-term facility than home. The 51 patients who went for EST within our system had 90-day good (mRS 0-2), bad (mRS 5-6), and mortality rates comparable to those from DAWN and DEFUSE-3 trials [Table]. Conclusions: In our system, only a small proportion of suspected strokes met criteria for EST during the EW. It was possible in a community setting to achieve 90-day outcomes that were comparable to those from clinical trials.

Abstract Background The prehospital identification of stroke patients with large-vessel occlusion (LVO), that should be immediately transported to a thrombectomy capable centre is an unsolved problem. Our aim was to determine whether implementation of a state-wide standard operating procedure (SOP) using the Los Angeles Motor Scale (LAMS) is feasible and enables correct triage of stroke patients to hospitals offering (comprehensive stroke centres, CSCs) or not offering (primary stroke centres, PSCs) thrombectomy. Methods Prospective study involving all patients with suspected acute stroke treated in a 4-month period in a state-wide network of all stroke-treating hospitals (eight PSCs and two CSCs). Primary endpoint was accuracy of the triage SOP in correctly transferring patients to CSCs or PSCs. Additional endpoints included the number of secondary transfers, the accuracy of the LAMS for detection of LVO, apart from stroke management metrics. Results In 1123 patients, use of a triage SOP based on the LAMS allowed triage decisions according to LVO status with a sensitivity of 69.2% (95% confidence interval (95%-CI): 59.0–79.5%) and a specificity of 84.9% (95%-CI: 82.6–87.3%). This was more favourable than the conventional approach of transferring every patient to the nearest stroke-treating hospital, as determined by geocoding for each patient (sensitivity, 17.9% (95%-CI: 9.4–26.5%); specificity, 100% (95%-CI: 100–100%)). Secondary transfers were required for 14 of the 78 (17.9%) LVO patients. Regarding the score itself, LAMS detected LVO with a sensitivity of 67.5% (95%-CI: 57.1–78.0%) and a specificity of 83.5% (95%-CI: 81.0–86.0%). Conclusions State-wide implementation of a triage SOP requesting use of the LAMS tool is feasible and improves triage decision-making in acute stroke regarding the most appropriate target hospital.

Abstract Purpose Mechanical thrombectomy (MT) is the first-line treatment in acute stroke patients presenting with large vessel occlusion (LVO). The efficacy of intravenous thrombolysis (IVT) prior to MT is being contested. The objective of this study was to evaluate the efficacy of MT without IVT in patients with no contraindications to IVT presenting directly to a tertiary stroke center with acute anterior circulation LVO. Materials and Methods We collected the data of 106 acute stroke patients who underwent MT in a single high-volume stroke center. Patients with anterior circulation LVO eligible for IVT and directly admitted to our institution who subsequently underwent MT were included. We recorded baseline clinical, laboratory, procedural, and imaging variables and technical, imaging, and clinical outcomes. The effect of intravenous thrombolysis on 3-month clinical outcome (mRS) was analyzed with univariate tests and binary and ordinal logistic regression analysis. Results Fifty-eight out of the 106 patients received IVT + MT. These patients had 2.6-fold higher odds of poorer clinical outcome in mRS shift analysis (p = 0.01) compared to MT-only patients who had excellent 3-month clinical outcome (mRS 0–1) three times more often (p = 0.009). There were no significant differences between the groups in process times, mTICI, or number of hemorrhagic complications. A trend of less distal embolization and higher number of device passes was observed among the MT-only patients. Conclusions MT without prior IVT was associated with an improved overall three-month clinical outcome in acute anterior circulation LVO patients.

Abstract Background Optimal blood pressure (BP) management during endovascular stroke treatment in patients with large-vessel occlusion is not well established. We aimed to investigate associations of BP during different phases of endovascular therapy with reperfusion and functional outcome. Methods We performed a post hoc analysis of a single-center prospective study that evaluated a new simplified procedural sedation standard during endovascular therapy (Keep Evaluating Protocol Simplification in Managing Periinterventional Light Sedation for Endovascular Stroke Treatment). BP during endovascular therapy in patients was managed according to protocol. Data from four different phases (baseline, pre-recanalization, post recanalization, and post intervention) were obtained, and mean BP values, as well as changes in BP between different phases and reductions in systolic BP (SBP) and mean arterial pressure (MAP) from baseline to pre-recanalization, were used as exposure variables. The main outcome was a modified Rankin Scale score of 0–2 three months after admission. Secondary outcomes were successful reperfusion and change in the National Institutes of Health Stroke Scale score after 24 h. Multivariable linear and logistic regression models were used for statistical analysis. Results Functional outcomes were analyzed in 139 patients with successful reperfusion (defined as thrombolysis in cerebral infarction grade 2b–3). The mean (standard deviation) age was 76 (10.9) years, the mean (standard deviation) National Institutes of Health Stroke Scale score was 14.3 (7.5), and 70 (43.5%) patients had a left-sided vessel occlusion. Favorable functional outcome (modified Rankin Scale score 0–2) was less likely with every 10-mm Hg increase in baseline (odds ratio [OR] 0.76, P = 0.04) and pre-recanalization (OR 0.65, P = 0.011) SBP. This was also found for baseline (OR 0.76, P = 0.05) and pre-recanalization MAP (OR 0.66, P = 0.03). The maximum Youden index in a receiver operating characteristics analysis revealed an SBP of 163 mm Hg and MAP of 117 mm Hg as discriminatory thresholds during the pre-recanalization phase to predict functional outcome. Conclusions In our protocol-based setting, intraprocedural pre-recanalization BP reductions during endovascular therapy were not associated with functional outcome. However, higher intraprocedural pre-recanalization SBP and MAP were associated with worse functional outcome. Prospective randomized controlled studies are needed to determine whether BP is a feasible treatment target for the modification of outcomes.
