Organization of Stroke Care System: Stroke Unit and Stroke Center

Abstract Background COVID-19 pandemic caused a decline in stroke care in several countries. The objective was to describe lockdown stroke care in a tertiary stroke center in Düsseldorf, Germany near Heinsberg, a German hot spot for COVID-19 in spring 2020. Methods In a retrospective, observational, single-center study, we compared all patients treated in our emergency department (ED), patients seen by a neurologist in the ED, ED patients suffering from ischemic and hemorrhagic strokes and transient ischemic attacks (TIAs) as well as stroke patients admitted to our stroke unit during lockdown in spring 2020 (16 March 2020–12 April 2020) to those cared for during the same period in 2019 and lockdown light in fall 2020 (2 November – 29 November 2020). Results In spring 2020 lockdown the mean number of patients admitted to our ED dropped by 37.4%, seen by a neurologist by 35.6%, ED stroke patients by 19.2% and number of patients admitted to our stroke unit by 10% compared to the same period in 2019. In fall lockdown light 2020 effects were comparable but less pronounced. Thrombolysis rate was stable during spring and fall lockdown, however, endovascular treatment (EVT) rate declined by 58% in spring lockdown and by 51% in fall lockdown compared to the period in 2019. Conclusions Our study indicates a profound reduction of overall ED patients, neurological ED patients and EVT during COVID-19 pandemic caused lockdowns. Planning for pandemic scenarios should include access to effective emergency therapies.

Background and purpose: In-hospital stroke-onset assessment and management present numerous challenges, especially in community hospitals. Comprehensive analysis of key stroke care metrics in community-based primary stroke centers is under-studied. Methods: Medical records were reviewed for patients admitted to a community hospital for non-cerebrovascular indications and for whom a stroke alert was activated between 2013 and 2019. Demographic, clinical, radiologic and laboratory information were collected for each incident stroke. Descriptive statistical analysis was employed. When applicable, Kruskal-Wallis and Chi-Square tests were used to compare median values and categorical data between pre-specified groups. Statistical significance was set at alpha = 0.05. Results: There were 192 patients with in-hospital stroke-alert activation; mean age (SD) was 71.0 years (15.0), 49.5% female. 51.6% (99/192) had in-hospital ischemic and hemorrhagic stroke. The most frequent mechanism of stroke was cardioembolism. Upon stroke activation, 45.8% had ischemic stroke while 40.1% had stroke mimics. Stroke team response time from activation was 26 minutes for all in-hospital activations. Intravenous thrombolysis was utilized in 8% of those with ischemic stroke; 3.4% were transferred for consideration of endovascular thrombectomy. In-hospital mortality was 17.7%, and the proportion of patients discharged to home was 34.4% for all activations. Conclusion: The in-hospital stroke mortality was high, and the proportions of patients who either received or were considered for acute intervention were low. Quality improvement targeting increased use of acute stroke intervention in eligible patients and reducing hospital mortality in this patient cohort is needed.

Clinical Care Pathway

Background: We review our initial experience of India’s and Asia’s first mobile stroke unit (MSU) following the completion of its first year of operation. We outline the clinical care pathway integrating the MSU services using a case example taking readers along our clinical care workflow while highlighting the challenges faced in organizing and optimizing such services in India. Methods: Retrospective review of data collected for all patients from March 2018 to February 2019 transported and treated within the MSU during the first year of its operation. Recent case example is reviewed highlighting complete comprehensive acute clinical care pathway from prehospital MSU services to advanced endovascular treatment with focus on challenges faced in developing nation for stroke care. Results: The MSU was dispatched and utilized for 14 patients with clinical symptoms of acute stroke. These patients were predominantly males (64%) with median age of 59 years. Ischemic stroke was seen in 7 patients, hemorrhagic in 6, and 1 patient was classified as stroke mimic. Intravenous tissue plasminogen activator was administered to 3 patients within MSU. Most of the patients’ treatment was initiated within 2 h of symptom onset and with the median time of patient contact (rendezvous) following stroke being 55 mins. Conclusion: Retrospective review of Asia’s first MSU reveals its proof of concept in India. Although the number of patients availing treatment in MSU is low as compared to elsewhere in the world, increased public awareness with active government support including subsidizing treatment costs could accelerate development of optimal prehospital acute stroke care policy in India.

Abstract:We assessed the impact of the coronavirus disease 19 (COVID-19) pandemic on code stroke activations in the emergency department, stroke unit admissions, and referrals to the stroke prevention clinic at London’s regional stroke center, serving a population of 1.8 million in Ontario, Canada. We found a 20% drop in the number of code strokes in 2020 compared to 2019, immediately after the first cases of COVID-19 were officially confirmed. There were no changes in the number of stroke admissions and there was a 22% decrease in the number of clinic referrals, only after the provincial lockdown. Our findings suggest that the decrease in code strokes was mainly driven by patient-related factors such as fear to be exposed to the SARS-CoV-2, while the reduction in clinic referrals was largely explained by hospital policies and the Government lockdown.

Abstract Background Since the onset of the coronavirus disease 2019 (COVID-19) pandemic, the stroke care systems have been seriously affected because of social restrictions and other reasons. As the pandemic continues to spread globally, it is of great significance to understand how COVID-19 affects the stroke care systems in mainland China. Methods We retrospectively studied the real-world data of one comprehensive stroke center in mainland China from January to February 2020 and compared it with the data collected during the same period in 2019. We analyzed DTN time, onset-to-door time, severity, effects after treatment, the hospital length of stays, costs of hospitalization, etc., and the correlation between medical burden and prognosis of acute ischemic stroke (AIS) patients. Results The COVID-19 pandemic was most severe in mainland China in January and February 2020. During the pandemic, there were no differences in pre-hospital or in-hospital workflow metrics (all p>0.05), while the degree of neurological deficit on admission and at discharge, the effects after treatment, and the long-term prognosis were all worse (all p<0.05). The severity and prognosis of AIS patients were positively correlated with the hospital length of stays and total costs of hospitalization (all p<0.05). Conclusions COVID-19 pandemic is threatening the stroke care systems. Measures must be taken to minimize the collateral damage caused by COVID-19.

BackgroundCurrent efforts to reduce door to groin puncture time (DGPT) aim to optimize clinical outcomes in stroke patients with large vessel occlusions (LVOs). The RapidAI mobile application (Rapid Mobile App) provides quick access to perfusion and vessel imaging in patients with LVOs. We hypothesize that utilization of RapidAI mobile application can significantly reduce treatment times in stroke care by accelerating the process of mobilizing stroke clinicians and interventionalists.MethodsWe analyzed patients presenting with LVOs between June 2019 and October 2020. Thirty-one patients were treated between June 2019 and March 2020 (pre-app group). Thirty-three patients presented between March 2020 and October 2020 (post-app group). Mann–Whitney U test and Kruskal–Wallis tests were used to examine variables that are not normally distributed. In a secondary analysis we analyzed interhospital time metrics between primary stroke centers and our comprehensive stroke center.ResultsBaseline demographic and vascular risk factors were similar in both groups. Use of Rapid Mobile App resulted in 33 min reduction in DGPT (P=0.02), 35 min reduction in door to first pass time (P=0.02), and 37 min reduction in door to recanalization time (P=0.02) in univariate analyses when compared with patients treated pre-app. In a multiple linear regression model, utilization of Rapid Mobile App significantly predicted shorter DGPT (P=0.002). In an adjusted model, National Institutes of Health Stroke Scale (NIHSS) 24 hours after procedure and at discharge were significantly lower in the post-app group (P=0.03). Time of transfer between primary and comprehensive stroke center was comparable in both groups (P=0.26).ConclusionIn patients with LVOs, the implementation of the RapidAI mobile application was independently associated with reductions in intrahospital treatment times.

Background: Nurse practitioner (NP) have a wider role in modern stroke centers providing quality evidence based care to patients in both in and outpatient settings for acute ischemic stroke (AIS) and transient ischemic attack (TIA) patients. We studied the outcome measures, length of stay (LOS) and cost before and after implementation of nurse practitioners as the primary medical provider in a community based stroke center. Methods: St Cloud hospital is acute care hospital with dedicated stroke service responsible for workup and management of all patients admitted with AIS and TIA. From March 2014-March 2015, all patients were primarily managed by stroke neurologists with or without support of NP, representing physician driven arm. From June 2015-March 2016 all non-critical patients were managed primarily by NP, representing the NP driven arm of care. For this analysis, we excluded all patients with subarachnoid hemorrhage or intracerebral hemorrhage. Using ICD codes, we abstracted LOS and hospitalization cost for all patients, and compared between two arms. Results: A total of 822 patients were included in physician arm and 336 in NP arm. The mean age was 72±14 years for both arms, and 54.4% were male in physician arm and 57.4% were male in NP arm. The mean total LOS for the physician arm was 3.1 ±3.3 days while 2.9±3.6 for NP arm (p=0.6). The total cost for physician arm was $11,286.70 ±$10,920.90 while the NP arm was $10,277.30± $10,142.30 (p=0.1). Conclusion: There is a trend towards lower cost and length of stay with implementation of NP as primary stroke provider for patients admitted with acute ischemic stroke.

Aims: In 2011, the VA released the Acute Ischemic Stroke (AIS) Directive which mandated reorganization of acute stroke care, including self-designation as Primary (P), Limited Hours (LH), or Supporting (S) stroke center. We conducted interviews across stroke centers to understand barriers and facilitators faced in response. Methods: The final sample included 38 (84% invited) facilities: 9 P, 24 LH, and 5 S facilities. In total, 107 persons were interviewed including ED Chiefs, Chiefs of Neurology, ED Nurse Managers/Nurses and other staff. Semi-structured interviews were based on the AIS Directive. Completed interviews were transcribed and analyzed using Nvivo 10. Results: Barriers reported were a lack of personnel assigned to coordinate the facility response to the directive. Data collection and lack of staff were likewise commonly reported as barriers. For thrombolysis measures, the low number of eligible Veterans was another major barrier. LH and S facilities reported some unique barriers: access to radiology and neurology services; EMS diverting stroke patients to nearby stroke centers, maintaining staff competency, and a lack of stroke clinical champions. Some solutions applied included cross training X-ray technicians to provide head CT coverage, developing stroke order sets and templates, and staff training. Larger facilities added a stroke code pager system and improved upon its use, and established ED nurses to become first alerts for an acute stroke patient. LH and S facilities also responded by attempting to secure additional services and by establishing formal transfer agreements to improve Veteran tPA access. Conclusions: The AIS Directive brought focused attention to reorganizing and improving stroke care across a range of facility types. Larger VA facilities tended to follow established practices for organizing stroke care, but the unique LH designation presented challenges to consistently organize systems. Since Veterans have financial interest in presenting to a VA facility, ongoing work to organize VA care and to improve access to thrombolysis at smaller VA facilities is needed. This protocol was supported by Genentech Inc. Protocol ML 28238, VA HSRD QUERI Rapid Response Project 11-374, and the VA Stroke QUERI Center.

Good Diagnostic Accuracy

A reliable and fast instrument for prehospital detection of large vessel occlusion (LVO) stroke would be a game-changer in stroke care, because it would enable direct transportation of LVO stroke patients to the nearest comprehensive stroke center for endovascular treatment. This strategy would substantially improve treatment times and thus clinical outcomes of patients. Here, we outline our view on the requirements of an effective prehospital LVO detection method, namely: high diagnostic accuracy; fast application and interpretation; user-friendliness; compactness; and low costs. We argue that existing methods for prehospital LVO detection, including clinical scales, mobile stroke units and transcranial Doppler, do not fulfill all criteria, hindering broad implementation of these methods. Instead, electroencephalography may be suitable for prehospital LVO detection since in-hospital studies have shown that quantification of hypoxia-induced changes in the electroencephalography signal have good diagnostic accuracy for LVO stroke. Although performing electroencephalography measurements in the prehospital setting comes with challenges, solutions for fast and simple application of this method are available. Currently, the feasibility and diagnostic accuracy of electroencephalography in the prehospital setting are being investigated in clinical trials.

Introduction : Stroke is a leading cause of morbidity, mortality and healthcare spending in the United States. Acute management of ischemic stroke is time‐dependent and evidence suggests improved clinical outcomes for patients treated at designated certified stroke centers. There is an increasing trend among hospitals to obtain certification as designated stroke centers. A common source or integrated tool providing both information and location of all available stroke centers in the US irrespective of the certifying organization is not readily available. The objective of our research is to generate a comprehensive and interactive electronic resource with combined data on all geographically‐coded certified stroke centers to assist in pre‐hospital triage and study healthcare disparities in stroke including availability and access to acute stroke care by location and population. Methods : Data on stroke center certification was primarily obtained from each of the three main certifying organizations: The Joint Commission (TJC), Det Norske Veritas (DNV) and Healthcare Facilities Accreditation Program (HFAP). Geographic mapping of all stroke center locations was performed using the ArcGIS Pro application. The most current data on stroke centers is presented in an interactive electronic format and the information is frequently updated to represent newly certified centers. Utility of the tool and its analytics are shown. Role of the tool in improving pre‐hospital triage in the stroke systems of care, studying healthcare disparities and implications for public health policy are discussed. Results : Aggregate data analysis at the time of submission revealed 1,806 total certified stroke centers. TJC‐certified stroke centers represent the majority with 106 Acute Stroke Ready (ASR), 1,040 Primary Stroke Centers (PSCs), 49 Thrombectomy Capable Centers (TSCs) and 197 Comprehensive Stroke Centers (CSCs). A total of 341 DNV‐certified programs including 36 ASRs, 162 PSCs, 16 PSC Plus (thrombectomy capable) and 127 CSCs were identified. HFAP‐certified centers (75) include 16 ASRs, 49 PSCs, 2 TSCs and 8 CSCs. A preliminary map of all TJC‐certified CSCs and TSCs is shown in the figure (1). Geospatial analysis reveals distinct areas with currently limited access to certified stroke centers and currently, access to certified stroke centers is extremely limited to non‐existent in fe States (for example: Idaho, Montana, Wyoming, New Mexico and South Dakota). Conclusions : Stroke treatment and clinical outcomes are time‐dependent and prompt assessment and triage by EMS directly to appropriate designated stroke centers is therefore critical. A readily available electronic platform providing location and treatment capability for all nearby certified centers will enhance regional stroke systems of care, including enabling more rapid inter‐hospital transfers for advanced intervention. Identifying geographic areas of limited access to treatment can also help improve policy and prioritize the creation of a more equitable and well‐distributed network of stroke care in the United States.
