Certification Requirements

Background and Purpose: There are currently three main, nationally recognized organizations that certify facilities as primary or comprehensive stroke centers. One of these organizations also offers a “Stroke Ready” designation. While each of these organizations share many of the same requirements, there are likewise many unique requirements between certifying bodies with respect to the certification requirements, process, performance, and on-going expectations. All should be considered when choosing a partner for certification by organizations that are committed to achieving an appropriate level of certification as determined by clinical capabilities. Differences in core measure requirements and definitions, data collection expectations and re-certification cycles among other factors are often overlooked when stroke program leaders are identifying the best certification partner for their particular organization. This poster will detail the similarities and differences among the various stroke program certifying organizations and present a detailed methodology to assist program leaders with the partner selection process. Methods: The three stroke program certifying organizations were examined for review cycles, levels of certification offered, requirements related to hospital certifications, and reportable core measures. Other factors such as cost, the actual certification process, and other considerations that may impact the successful achievement of certification within a particular organization were also reviewed. Results/Conclusion: While there are many similarities in the stroke center certification requirements and processes among the three certifying organizations, there are also significant differences. In order to ensure that the end product of a journey to certification will align with a hospital’s values, budget, and vision for the stroke program, an evaluation process in advance of certifying body selection is essential. Awareness of the similarities and differences among the stroke certification organizations can facilitate a hospital’s decision-making process for pursuit of certification as a stroke ready center, primary stroke center or comprehensive stroke center

Background Patients with acute ischemic stroke (AIS) caused by large vessel occlusion (LVO) were usually transferred from a primary stroke center (PSC) to a comprehensive stroke center (CSC) for endovascular treatment (drip-and-ship [DS]), while driving the doctor from a CSC to a PSC to perform a procedure is an alternative strategy (drip-and-drive [DD]). Purpose To compare the efficacy and prognosis of the two strategies. Material and Methods From February 2017 to June 2019, 62 patients with LVO received endovascular treatment via the DS and DD models and were retrospectively analyzed from the stroke alliance based on our CSC. Primary endpoint was door-to-reperfusion (DTR) time. Secondary endpoints included puncture-to-recanalization (PTR) time, modified Thrombolysis in Cerebral Infarction (mTICI) rates at the end of the procedure, and modified Rankin Scale (mRS) at 90 days. Results Forty-one patients received the DS strategy and 21 patients received the DD strategy. The DTR time was significantly longer in the DS group compared to the DD group (315.5 ± 83.8 min vs. 248.6 ± 80.0 min; P < 0.05), and PTR time was shorter (77.2 ± 35.9 min vs. 113.7 ± 69.7 min; P = 0.033) compared with the DD group. Successful recanalization (mTICI 2b/3) was achieved in 89% (36/41) of patients in the DS group and 86% (18/21) in the DD group ( P = 1.000). Favorable functional outcomes (mRS 0–2) were observed in 49% (20/41) of patients in the DS group and 71% (15/21) in the DD group at 90 days ( P = 0.089). Conclusion Compared with the DS strategy, the DD strategy showed more effective and a trend of better clinical outcomes for AIS patients with LVO.

Background Functional outcome post-stroke depends on time to recanalization. Effect of in-hospital delay may differ in patients directly admitted to a comprehensive stroke center and patients transferred via a primary stroke center. We analyzed the current door-to-groin time in Germany and explored its effect on functional outcome in a real-world setting. Methods Data were collected in 25 stroke centers in the German Stroke Registry-Endovascular Treatment a prospective, multicenter, observational registry study including stroke patients with large vessel occlusion. Functional outcome was assessed at three months by modified Rankin Scale. Association of door-to-groin time with outcome was calculated using binary logistic regression models. Results Out of 4340 patients, 56% were treated primarily in a comprehensive stroke center and 44% in a primary stroke center and then transferred to a comprehensive stroke center (“drip-and-ship” concept). Median onset-to-arrival at comprehensive stroke center time and door-to-groin time were 103 and 79 min in comprehensive stroke center patients and 225 and 44 min in primary stroke center patients. The odds ratio for poor functional outcome per hour of onset-to-arrival-at comprehensive stroke center time was 1.03 (95%CI 1.01–1.05) in comprehensive stroke center patients and 1.06 (95%CI 1.03–1.09) in primary stroke center patients. The odds ratio for poor functional outcome per hour of door-to-groin time was 1.30 (95%CI 1.16–1.46) in comprehensive stroke center patients and 1.04 (95%CI 0.89–1.21) in primary stroke center patients. Longer door-to-groin time in comprehensive stroke center patients was associated with admission on weekends (odds ratio 1.61; 95%CI 1.37–1.97) and during night time (odds ratio 1.52; 95%CI 1.27–1.82) and use of intravenous thrombolysis (odds ratio 1.28; 95%CI 1.08–1.50). Conclusion Door-to-groin time was especially relevant for outcome of comprehensive stroke center patients, whereas door-to-groin time was much shorter in primary stroke center patients.

BackgroundEndovascular therapy (EVT) for stroke improves outcomes but is time sensitive.ObjectiveTo compare times to treatment and outcomes between patients taken to the closest primary stroke center (PSC) with those triaged in the field to a more distant comprehensive stroke center (CSC).MethodsDuring the study, a portion of our region allowed field triage of patients who met severity criteria to a more distant CSC than the closest PSC. The remaining patients were transported to the closest PSC. We compared times to treatment and clinical outcomes between those two groups. Additionally, we performed a matched-pairs analysis of patients from both groups on stroke severity and distance to CSC.ResultsOver 2 years, 232 patients met inclusion criteria and were closest from the field to a PSC; 144 were taken to the closest PSC and 88 to the more distant CSC. The median additional transport time to the CSC was 7 min. Times from scene departure to alteplase and arterial puncture were faster in the direct group (50 vs 62 min; 93 vs 152 min; p<0.001 for both). Among patients who were independent before the stroke, the OR for less disability in the direct group was 1.47 (95% CI 1.13 to 1.93, p=0.003), and 2.06 (95% CI 1.10 to 3.89, p=0.01) for the matched pairs.ConclusionsIn a densely populated setting, for patients with stroke who are EVT candidates and closest to a PSC from the field, triage to a slightly more distant CSC is associated with faster time to EVT, no delay to alteplase, and less disability at 90 days.

Radiographic Data

Introduction: Decreases in blood pressure (BP) during thrombectomy are associated with infarct progression and worse outcomes. Many patients present first to a primary stroke center (PSC) and are later transferred to a comprehensive stroke center (CSC) to undergo thrombectomy. During this period, important BP variations might occur. We evaluated the association of BP reductions with neurological worsening and functional outcomes. Methods: We prospectively collected hemodynamic, clinical, and radiographic data on consecutive patients with LVO ischemic stroke who were transferred from a PSC for possible thrombectomy between 2018 and 2020. We assessed systolic BP (SBP) and mean arterial pressure (MAP) at five time points: earliest recorded, average pre-PSC, PSC admission, average PSC, and CSC admission. We measured neurologic worsening as a change in NIHSS (ΔNIHSS) from PSC to CSC >3 and functional outcome using the modified Rankin Scale (mRS) at discharge and 90 days. Relationships between variables of interest were evaluated using linear regression. Results: Of 91 patients (mean age 70±16 years, mean NIHSS 12) included, 13 (14%) experienced early neurologic deterioration (ΔNIHSS>3), and 34 (37%) achieved a good outcome at discharge (mRS<3). We found that patients with good outcome had significantly lower SBP at all five assessed time points compared to patients with poor outcome (Figure 1, p<0.05). Percent change in MAP from initial presentation to CSC arrival was independently associated with ΔNIHSS after adjusting for age, sex, and transfer time (p=0.03, β=0.27). Conclusions: Patients with poor outcomes have higher BP throughout the pre-CSC period, possibly reflecting an augmented hypertensive response. Reductions in SBP and MAP before arrival at the CSC are associated with neurologic worsening. These results suggest that BP management strategies in the pre-CSC period to avoid large reductions in BP may improve outcomes in patients affected by LVO stroke.

Introduction: Given the time-sensitive benefits of acute stroke (AS) treatments, stroke systems of care must balance reducing door-in-door-out (DIDO) time at primary stroke centers (PSCs) with capacity limits at comprehensive stroke centers (CSCs). For example transferring more AS patients earlier in the process (e.g., prior vascular imaging for large vessel occlusion) from PSCs would result in more inappropriate transfers to CSCs that could overburden these centers.We conducted a simulation to estimate the balance between increased AS transfers from PSCs to CSCs and the percent of CSC time on “bypass” (inability to accept transfers to neuro-ICU). Methods: Clinicians from 3 Chicago-area CSCs and 3 affiliated PSCs and the Chicago Emergency Medical Services (EMS) created a PSC DIDO process map. We assumed CSC time on bypass is affected by AS and non-AS admissions from the CSC and from the affiliated PSCs. Input data were obtained fromtheChicago region registry (e.g., # PSC to CSC transfers), peer reviewed literature (US average transfer rate of AS patients to CSCs), EMS (PSC-CSC affiliations), and CSCs (e.g., average bed occupancy rates). CSC size was estimated by #neuro-ICU beds: small (12 beds), medium (23 beds), and large (28 beds). The simulation output was % time of CSC on “bypass”. Results: Table shows % time of CSC on bypass by varying PSC AS transfer rates for each category of CSC size. Larger increases in PSC transfer rates resulted in modest increases in CSC bypass rates, particularly for medium and large CSCs. Validation with data from one CSC showed < 4% overestimate of CSC % time on bypass. Conclusion: CSCs with more beds have efficiencies of scale leading to lower % time on bypass, even with increases in PSC AS transfer rates proportionate to CSC size. This model allows stroke systems of care to compute regional CSCs’ % time on bypass based on actual PSCs’ transfer rates and CSC size.

According to The Journal of Emergency Medical Services (EMS) the goal of stroke care is to minimize brain injury and maximize recovery. The stroke chain of survival links actions taken by patients, family, EMS and healthcare providers. Recent innovations in stroke treatment require accurate identification and appropriate triage to the appropriate treatment facility. Evidence in the literature demonstrates variability with EMS correct identification of stroke patients between 30% and 80%. Our 164 bed primary stroke center in rural Pennsylvania has been active in providing stroke education on an annual basis to emergency medical services within a two county radius. As part of our ongoing process improvement we wanted to evaluate the emergency medical technicians and paramedics knowledge of stroke signs and symptoms, their understanding of the evaluation, treatment and triage of stroke patients. A standard questionnaire with 14 variables was developed using the American Heart and Stroke Association prehospital guidelines. The questionnaire included 16 stroke and non stroke symptoms, identifying transport to primary verses comprehensive stroke centers and initial evaluation. A sample population of 90 emergency medical service staff were asked to complete the questionnaire with 28 (31%) responses received. All participants indicated they were confident to recognize stroke signs and symptoms but 6 of the non stroke items were chosen as stroke symptoms. All participants indicated they were confident in the initial evaluation of a stroke patient but 14 (50%) appropriately identified airway, breathing, circulation as the first evaluation. Evaluating triage knowledge, 26 (93%) stated confidence in decision to transport to a primary stroke center and 22 (79%) to a comprehensive stroke center, however, appropriate decision to transport to a primary stroke center was identified correctly by 46% a comprehensive stroke center 66%. In conclusion, results from this study suggest that in this rural setting, barriers exist in prehospital recognition and evaluation of the stroke patient for which proper education may be remediable. Our goal is to use this information to revise our current EMS stroke education program and enhance prehospital assessment and triage.

Background and Purpose: The safety and efficacy of intravenous tissue plasminogen activator (IV tPA) following acute ischemic stroke (AIS) is dependent on its timely administration. In 2014, our Comprehensive Stroke Center designed and implemented a computed tomography-Direct protocol to streamline the evaluation process of suspected patients with AIS, with the aim of reducing door-to-needle (DTN) times. The objectives of our study were to describe the protocol development and implementation process, and to compare DTN times and symptomatic intracranial hemorrhage (sICH) rates before and after protocol implementation. Methods: Data were prospectively collected for patients with AIS receiving IV tPA between January 1, 2010, and May 31, 2015. The DTN times, examined as median times and time treatment windows, and sICH rates were compared pre- and postimplementation. Results: Two hundred ninety-five patients were included in the study. After protocol implementation, median DTN times were significantly reduced (38 vs 28 minutes; P < .001). The distribution of patients treated in the three time treatment windows described below changed significantly, with an increase in patients with DTN times of 30 minutes or less, and a decrease in patients with DTN times 31 to 60 minutes and over 60 minutes ( P < .001). There were two cases of sICH prior to implementation and one sICH case postimplementation. Conclusions: The implementation of a protocol that streamlined the processing of suspected patients with AIS significantly reduced DTN time without negatively impacting patient safety.

Background No comprehensive study exists about mechanical thrombectomy accessibility for patients admitted to a primary stroke center without onsite interventional neuroradiology service. Aims To evaluate mechanical thrombectomy accessibility within 6 h after transfer from a primary stroke center to a distant (156 km apart; 1.5 h by car) comprehensive stroke center. Methods Analysis of data collected in a three-year prospective registry on patients admitted to a primary stroke center within 4.5 h after symptom onset and selected for transfer to a comprehensive stroke center for mechanical thrombectomy. Eligible patients had confirmed proximal arterial occlusion and no large cerebral infarction on MRI images (DWI-ASPECTS ≥ 5). The rate of transfer, transfer without mechanical thrombectomy, mechanical thrombectomy, reperfusion (TICI score ≥ 2b-3), and the main relevant time measures were determined. Results Among the 385 patients selected for intravenous thrombolysis and/or potential mechanical thrombectomy, 211 were considered as transferrable for mechanical thrombectomy. The rate of transfer was 56.4% (n = 119/211), transfer without mechanical thrombectomy 56.3% (n = 67/119), mechanical thrombectomy 24.6% (n = 52/211), and reperfusion by MT (TICI score 2b/3) 18% (n = 38/211). The relevant median times (interquartile range) were: 130 min (62) for intravenous thrombolysis start to comprehensive stroke center door, 95 minutes (39) for primary stroke center door-out to comprehensive stroke center door-in, 191 min (44) for intravenous thrombolysis start to mechanical thrombectomy puncture, 354 min (107) for symptom onset to mechanical thrombectomy puncture and 417 min (124) for symptom onset to recanalization. Conclusions Our study suggests that transfer to a distant comprehensive stroke center is associated with reduced access to early mechanical thrombectomy in patients with acute ischemic stroke and large artery occlusion. These results could be translated to other high volume distant primary stroke center.

Introduction: Acute stroke (AS) is a highly time sensitive treatment condition affecting approximately 800,000 people/year in the US. Most AS patients receive care at a primary stroke center (PSC), but some require more advanced treatments, and rely on a timely transfer to a comprehensive stroke center (CSC) where such treatments can be given. Stroke teams at 2 Chicago area PSCs and 4 CSCs, collectively, developed solutions (Graph) targeting both reported and perceived failures/delays/weakness in the current PSC door-in-door-out (DIDO) process for transferring patients to a CSC. The study simulates the potential impact of the solutions on DIDO. Methods: Current state (baseline) times were calculated from time stamps in the electronic health record (EHR) (e.g., door to CT), estimated by the stroke teams (e.g., hand-off time) or retrieved (e.g., DIDO, door to stroke activation) from a prospectively maintained REDCap data registry (2/2018-1/2020). Proportions (e.g., % with ischemic stroke, % transferred) were estimated from hospital data. Changes in times after implementation of a solution were obtained from peer reviewed literature, when available, or by consensus expert opinion. Simio (version 11.197.19514) was used to simulate the current and future states with implementation of the solutions, with 500 replications, to estimate changes in DIDO. Results: Implementation of all solutions would achieve a decrease in DIDO of 33 minutes (19%) from current state. The largest driver of this change was direct to CT/CTA protocol implementation (21 minutes) followed by using a handoff tool for paramedics prior to transfer (13 minutes). Conclusion: The proposed solutions can achieve nearly a 20% reduction in DIDO times. The “Direct to CT/CTA Protocol” solution is the major driver of the improvement. Data simulation is helpful by assessing the potential impact of many solutions and the relative impact of each solution to inform implementation decisions.
