Abstract
PURPOSE Improved outcomes have been noted in patients undergoing malignant brain tumor resection at high-volume centers. Studies have arbitrarily chosen high-volume dichotomous cutoffs and have not evaluated volume-outcome associations at specific institutional procedural volumes. We sought to establish the continuous association of volume with patient outcomes and identify cutoffs significantly associated with mortality, major complications, and readmissions. We hypothesized that a linear volume-outcome relationship can estimate likelihood of adverse outcomes when comparing any two volumes. METHODS The patient cohort was identified with ICD-10 coding in the Nationwide Readmissions Database(NRD). The association of volume and mortality, major complications, and 30-/90-day readmissions were evaluated in multivariate analyses. Volume was used as a continuous variable with two/three-piece splines, with various knot positions to reflect the best model performance, based on the Quasi Information Criterion(QIC). RESULTS From 2016 to 2018, 34,486 patients with malignant brain tumors underwent resection. When volume was analyzed as a continuous variable, mortality risk decreased at a steady rate of OR 0.988 per each additional procedure increase for hospitals with 1-65 cases/year(95% CI 0.982-0.993, p < 0.0001). Risk of major complications decreased from 1 to 41 cases/year(OR 0.983, 95% CI 0.979-0.988, p < 0.0001), 30-day readmissions from 1 to 24 cases/year(OR 0.987, 95% CI 0.979-0.995, p = 0.001) and 90-day readmissions from 1 to 23 cases/year(OR 0.989, 95% CI 0.983-0.995, p = 0.0003) and 24-349 cases/year(OR 0.9994, 95% CI 0.999-1, p = 0.01). CONCLUSION In multivariate analyses, institutional procedural volume remains linearly associated with mortality, major complications, and 30-/90-day readmission up to specific cutoffs. The resulting linear association can be used to calculate relative likelihood of adverse outcomes between any two volumes.

Abstract
AIMS Type 2 diabetes (T2D) is a risk factor for ischemic stroke (IS) and associated with an adverse prognosis. Both stroke and diabetes care has evolved substantially during the last decade. This study aimed to determine the prevalence of T2D among IS patients along with time trends in the risk profile, use of glucose-lowering medications, quality-of-care and clinical outcomes, including stroke severity; length-of-stay; mortality, readmission and recurrent stroke in a large national cohort. METHODS Registry-based cohort study including all IS events in Denmark from 2004 to 2020. IS with co-morbid T2D were compared to IS without diabetes while adjusting for age, sex, stroke severity, co-morbidity and socio-economic factors. RESULTS The study included 169,262 IS events; 24,479 with co-morbid T2D. The prevalence of T2D in IS increased from 12.0% (2004-2006) to 17.0% (2019-2020). The adjusted absolute 30-day mortality risk in IS with T2D decreased from 9.9% (2004-2006) to 7.8% (2019-2020). The corresponding adjusted risk ratios (aRR) were 1.22 95% confidence interval (1.09-1.37) and 1.29 (1.11-1.50), respectively. The aRR of 365-day mortality was in 2004-2006: 1.20 (1.12-1.29) and in 2019-2020: 1.34 (1.22-1.47). The 30- and 365-day readmissions rates were also consistently higher in IS with T2D. CONCLUSIONS The prevalence of T2D in IS increased over time. The 30- and 365-day mortality rates decreased over the time-period but were consistently higher in IS with co-morbid T2D. Readmissions were also higher in IS with T2D. This highlights an urgent need for strategies to further improve the prognosis in IS patients with co-morbid T2D.

Abstract
Stroke is a predominant contributor to global mortality and disability and represents a complex and heterogeneous disease characterized by diverse risk factors and clinical presentations. The likelihood of stroke patients being at risk of a second stroke within the first five years is higher, especially within the initial two weeks. The distressing prospect of experiencing recurrent stroke shortly after reperfusion therapy adds an additional layer of complexity, potentially reversing prior progress. In the present case, we describe a patient who experienced a recurrent stroke within 24 hours, affecting the contralateral middle cerebral artery (MCA). This recurrence occurred after the individual underwent thrombolysis therapy for the initial stroke, emphasizing the intricate challenges associated with managing such cases and the imperative for targeted interventions to mitigate further risks and enhance patient outcomes.

Abstract
To investigate the association between the Emergency Medical Service dispatcher's initial stroke triage and prehospital stroke management, primary admission to hospitals offering revascularization treatment, prehospital time delay, and rate of acute revascularization. In an observational cohort study, patients with acute ischemic stroke (AIS) in Denmark (2017-2018) were included if the emergency call to the Emergency Medical Dispatch Center (EMDC) was made within three hours after symptom onset. Among 3546 included AIS patients, the EMS dispatcher identified 74.6% (95% confidence interval (CI) 73.1-76.0) correctly as stroke. EMS dispatcher stroke recognition was associated with a higher rate of primary admission to a hospital offering revascularization treatment (85.8 versus 74.5%); producing an adjusted risk difference (RD) of 11.1% (95% CI 7.8; 14.3) and a higher rate of revascularization treatment (49.6 versus 41.6%) with an adjusted RD of 8.4% (95% CI 4.6; 12.2). We adjusted for sex, age, previous stroke or transient ischemic attack, and stroke severity. EMDC stroke recognition was associated with shorter prehospital delay. For all AIS patients, the adjusted difference was - 33.2 min (95% CI - 44.4; - 22.0). Among patients receiving acute revascularization treatment (n = 1687), the adjusted difference was -12.6 min (95% CI - 18.9; - 6.3). Stroke recognition by the EMS dispatcher was associated with a higher probability of primary admission to a hospital offering acute stroke treatment, and subsequently with a higher rate of acute revascularization treatment, and with an overall reduction in prehospital delay.

Syed MJ, Zutshi D, Khawaja A, Basha MM, Marawar R. Understanding the Influence of Hospital Volume on Inpatient Outcomes Following Hospitalization for Status Epilepticus. Neurocrit Care 2023; 38:26-34. [PMID: 36522515 DOI: 10.1007/s12028-022-01656-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Accepted: 11/17/2022] [Indexed: 12/23/2022]
Abstract
BACKGROUND Prior studies show hospital admission volume to be associated with poor outcomes following elective procedures and inpatient medical hospitalizations. However, it is unknown whether hospital volume impacts Inpatient outcomes for status epilepticus (SE) hospitalizations. In this study, we aimed to assess the impact of hospital volume on the outcome of patients with SE and related inpatient medical complications. METHODS The 2005 to 2013 National Inpatient Sample database was queried using International Classification of Diseases 9th Edition diagnosis code 345.3 to identify patients undergoing acute hospitalization for SE. The National Inpatient Sample hospital identifier was used as a unique facility identifier to calculate the average volume of patients with SE seen in a year. The study cohort was divided into three groups: low volume (0-7 patients with SE per year), medium volume (8-22 patients with SE per year), and high volume (> 22 patients with SE per year). Multivariate logistic regression analyses were used to assess whether medium or high hospital volume had lower rates of inpatient medical complications compared with low-volume hospitals. RESULTS A total of 137,410 patients with SE were included in the analysis. Most patients (n = 50,939; 37%) were treated in a low-volume hospital, 31% (n = 42,724) were treated in a medium-volume facility, and 18% (n = 25,207) were treated in a high-volume hospital. Patients undergoing treatment at medium-volume hospitals (vs. low-volume hospitals) had higher odds of pulmonary complications (odds ratio [OR] 1.18 [95% confidence interval {CI} 1.12-1.25]; p < 0.001), sepsis (OR 1.24 [95% CI 1.08-1.43] p = 0.002), and length of stay (OR 1.13 [95% CI 1.0 -1.19] p < 0.001). High-volume hospitals had significantly higher odds of urinary tract infections (OR 1.21 [95% CI 1.11-1.33] p < 0.001), pulmonary complications (OR 1.19 [95% CI 1.10-1.28], p < 0.001), thrombosis (OR 2.13 [95% CI 1.44-3.14], p < 0.001), and renal complications (OR 1.21 [95% CI 1.07-1.37], p = 0.002). In addition, high-volume hospitals had lower odds of metabolic (OR 0.81 [95% CI 0.72-0.91], p < 0.001), neurological complications (OR 0.80 [95% CI 0.69-0.93], p = 0.004), and disposition to a facility (OR 0.89 [95% CI 0.82-0.96], p < 0.001) compared with lower-volume hospitals. CONCLUSIONS Our study demonstrates certain associations between hospital volume and outcomes for SE hospitalizations. Further studies using more granular data about the type, severity, and duration of SE and types of treatment are warranted to better understand how hospital volume may impact care and prognosis of patients.

Can Helicopters Solve the Transport Dilemma for Patients With Symptoms of Large-Vessel Occlusion Stroke in Intermediate Density Areas? A Simulation Model Based on Real Life Data. Front Neurol 2022; 13:861259. [PMID: 35547365 PMCID: PMC9082641 DOI: 10.3389/fneur.2022.861259] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Accepted: 03/21/2022] [Indexed: 11/26/2022] Open
Abstract
Background This modeling study aimed to determine if helicopters may optimize the transportation of patients with symptoms of large vessel stroke in “intermediate density” areas, such as Denmark, by bringing them directly to the comprehensive stroke center. Methods We estimated the time for the treatment of patients requiring endovascular therapy or intravenous thrombolysis under four configurations: “drip and ship” with and without helicopter and “bypass” with and without helicopter. Time delays, stroke numbers per municipality, and helicopter dispatches for four helicopter bases from 2019 were obtained from the Danish Stroke and Helicopter Registries. Discrete event simulation (DES) was used to estimate the capacity of the helicopter fleet to meet patient transport requests, given the number of stroke codes per municipality. Results The median onset-to-needle time at the comprehensive stroke center (CSC) for the bypass model with the helicopter was 115 min [interquartile range (IQR): 108, 124]; the median onset-to-groin time was 157 min (IQR: 150, 166). The median onset-to-needle time at the primary stroke center (PSC) by ground transport was 112 min (IQR: 101, 125) and the median onset-to-groin time when primary transport to the PSC was prioritized was 234 min (IQR: 209, 261). A linear correlation between travel time by ground and the number of patients transported by helicopter (rho = 0.69, p < 0.001) indicated that helicopters are being used to transport more remote patients. DES demonstrated that an increase in helicopter capture zone by 20 min increased the number of rejected patients by only 5%. Conclusions Our model calculations suggest that using helicopters to transport patients with stroke directly to the CSC in intermediate density areas markedly reduce onset-to-groin time without affecting time to thrombolysis. In this setting, helicopter capacity is not challenged by increasing the capture zone.

Abstract
OBJECTIVES To investigate the impact of the Danish stroke campaign, 1 year after initiation. MATERIALS & METHODS The campaign ran in various media during 2019-2020. We performed a two-centre, repeated cross-sectional study in 2018 (before campaign) and again in 2020 based on data from structured interviews of patients and bystanders, medical records and the Danish Stroke Registry. Primary outcomes were patient delay and system delay. Patient delay is defined as the time from symptom onset until the first contact to a healthcare professional, whereas system delay is the time from this contact until arrival at the stroke centre. Secondary outcomes were primary emergency medical services (EMS) contact, arrival at a stroke centre within 3 h of symptom onset, initiation of reperfusion therapy and knowledge of ≥2 core symptoms of stroke. RESULTS We included 852 patients with stroke or transient ischemic attack. Patient delay and system delay were a median of 166 min and 96 min before the campaign and were non-significantly reduced by 16 min (95% CI -128 to 97) and 7 min (95% CI -21 to 6) in the second period. We found no significant differences in the clinical outcomes. The knowledge of ≥2 core symptoms increased from 22% to 30% (OR 1.63; 95% CI 1.15 to 2.30) in patients and from 53% to 65% (OR 1.81; 95% CI 1.24 to 2.64) in bystanders. CONCLUSION Patient delay, system delay and clinical outcomes remained relatively unchanged. However, the knowledge of core symptoms had improved 1 year after campaign initiation.

Abstract
Globally, there is a rise in incident cases of stroke, particularly in low- and middle-income countries, due to obesity-related and lifestyle risk factors, including health issues such as high cholesterol, diabetes and hypertension. Since the early 20th century, stroke mortality has declined due to proper management of the risk factors and improved treatment practices. However, despite the decline in mortality, there is an increase in the levels of disability that requires long-term support. In countries such as Australia and Denmark, where most care is provided within the community; family members, generally spouses, assume the role of caregiver, with little to no preparation that affects the quality of care provided to the person living with stroke. While past research has highlighted aspects to improve caregiver preparedness of stroke and its impact on care; health planning, recovery, and public health policies rarely consider these factors, reducing engagement and increasing uncertainty. Hence, there is a need to focus on improving strategies during recovery to promote caregiver engagement. In this study, we, therefore, try to understand the needs of the caregiver in stroke that limit engagement, and processes employed in countries such as Australia and Denmark to provide care for the person with stroke. Based on our understanding of these factors, we highlight the potential opportunities and challenges to promote caregiving engagement in these countries.

Abstract
OBJECTIVES Prehospital delay is the main reason why only a limited number of stroke patients receive reperfusion therapy. We aimed to investigate help-seeking behaviour in patients and bystanders after onset of stroke and subsequent patient and system delay. MATERIALS & METHODS We conducted a cross-sectional study of 332 patients with stroke. We performed structured interviews and used data from the medical records and the Danish Stroke Registry. Primary outcomes were patient delay and system delay. RESULTS The median patient delay was 280 min, and the median system delay was 97 min. For a patient delay of <3 h, an additional non-significant system delay of median 30 min was seen for a first contact to a general practitioner (GP), and an additional significant delay of median 490 min was seen for the small group of patients with a first contact to 'other' healthcare professionals compared to the Emergency Medical Services (EMS). For a patient delay of more than 3 h, an additional system delay of median 78 min was found when the first contact was directed to the out-of-hours primary care (OOH-PC). A total of 17% of patients were admitted to another hospital or department before arrival at the stroke centre; this resulted in a substantially prolonged system delay of a median of 431 min. CONCLUSIONS Patient delay remains the main reason for delayed arrival at the stroke centre. Appropriate help-seeking behaviour and efficient pre-hospital triage are essential for reducing the prehospital delay and increasing the proportion of patients receiving reperfusion therapy.

Relationship between primary stroke center volume and time to endovascular thrombectomy in acute ischemic stroke. Eur J Neurol 2021; 28:4031-4038. [PMID: 34528335 PMCID: PMC9292965 DOI: 10.1111/ene.15107] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Revised: 09/03/2021] [Accepted: 09/09/2021] [Indexed: 11/29/2022]
Abstract
Background and purpose We investigated whether the annual volume of patients with acute ischemic stroke referred from a primary stroke center (PSC) for endovascular treatment (EVT) is associated with treatment times and functional outcome. Methods We used data from the Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands (MR CLEAN) registry (2014–2017). We included patients with acute ischemic stroke of the anterior circulation who were transferred from a PSC to a comprehensive stroke center (CSC) for EVT. We examined the association between EVT referral volume of PSCs and treatment times and functional outcome using multivariable regression modeling. The main outcomes were time from arrival at the PSC to groin puncture (PSC‐door‐to‐groin time), adjusted for estimated ambulance travel times, time from arrival at the CSC to groin puncture (CSC‐door‐to‐groin time), and modified Rankin Scale (mRS) score at 90 days after stroke. Results Of the 3637 patients in the registry, 1541 patients (42%) from 65 PSCs were included. Mean age was 71 years (SD ± 13.3), median National Institutes of Health Stroke Scale score was 16 (interquartile range [IQR]: 12–19), and median time from stroke onset to arrival at the PSC was 53 min (IQR: 38–90). Eighty‐three percent had received intravenous thrombolysis. EVT referral volume was not associated with PSC‐door‐to‐groin time (adjusted coefficient: −0.49 min/annual referral, 95% confidence interval [CI]: −1.27 to 0.29), CSC‐door‐to‐groin time (adjusted coefficient: −0.34 min/annual referral, 95% CI: −0.69 to 0.01) or 90‐day mRS score (adjusted common odds ratio: 0.99, 95% CI: 0.96–1.01). Conclusions In patients transferred from a PSC for EVT, higher PSC volumes do not seem to translate into better workflow metrics or patient outcome.

Intern Med J 2021; 50:965-971.

Abstract
BACKGROUND Advances in stroke management such as acute stroke units and thrombolysis are not uniformly distributed throughout our population, with rural areas being relatively disadvantaged. It remains unclear, however, whether such disparities have led to corresponding differences in patient outcomes. AIMS To describe the regional differences in acute ischaemic stroke care and outcomes within the Australian state of Tasmania. METHODS A retrospective case note audit was used to assess the care and outcomes of 395 acute ischaemic stroke patients admitted to Tasmania's four major public hospitals. Sixteen care processes were recorded, which covered time-critical treatment, allied health interventions and secondary prevention. Outcome measures were assessed using 30-day mortality and discharge destination, both of which were analysed for differences between urban and rural hospitals using logistic regression. RESULTS No patients in rural hospitals were administered thrombolysis; these hospitals also did not have acute stroke units. With few exceptions, patients' access to the remaining care indicators was comparable between regions. After adjusting for confounders, there were no significant differences between regions in terms of 30-day mortality (odds ratio (OR) = 0.99, 95% confidence interval (CI) 0.46-2.18) or discharge destination (OR = 1.24, 95% CI 0.81-1.91). CONCLUSIONS With the exception of acute stroke unit care and thrombolysis, acute ischaemic stroke care within Tasmania's urban and rural hospitals was broadly similar. No significant differences were found between regions in terms of patient outcomes. Future studies are encouraged to employ larger data sets, which capture a broader range of urban and rural sites and record patient outcomes at extended interval.

Specialized Outpatient Clinic vs Stroke Unit for TIA and Minor Stroke: A Cohort Study. Neurology 2021; 96:e1096-e1109. [PMID: 33472916 PMCID: PMC8055342 DOI: 10.1212/wnl.0000000000011453] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Accepted: 10/21/2020] [Indexed: 12/25/2022] Open
Abstract
OBJECTIVE To evaluate the effects of an outpatient clinic setup for minor stroke/TIA using subsequent admission of patients at high risk of recurrent stroke. METHODS We performed a cohort study of all patients with suspected minor stroke/TIA seen in an outpatient clinic at Aarhus University Hospital, Denmark, between September 2013 and August 2014. Patients with stroke were compared to historic (same hospital) and contemporary (another comparable hospital) matched, hospitalized controls on nonprioritized outcomes: length of stay, readmissions, care quality (10 process-performance measures), and mortality. Patients with TIA were compared to contemporary matched, hospitalized controls. Following complete diagnostic workup, patients with stroke/TIA were classified into low/high risk of recurrent stroke ≤7 days. RESULTS We analyzed 1,076 consecutive patients, of whom 253 (23.5%) were subsequently admitted to the stroke ward. Stroke/TIA was diagnosed in 215/171 patients, respectively. Fifty-six percent (121/215) of the patients with stroke were subsequently admitted to the stroke ward. Comparison with the historic stroke cohort (n = 191) showed a shorter acute hospital stay for the strokes (median 1 vs 3 days; adjusted length of stay ratio 0.49; 95% confidence interval 0.33-0.71). Thirty-day readmission rate was 3.2% vs 11.6% (adjusted hazard ratio 0.23 [0.09-0.59]), and care quality was higher, with a risk ratio of 1.30 (1.15-1.47). The comparison of stroke and TIAs to contemporary controls showed similar results. Only one patient in the low risk category and not admitted experienced stroke within 7 days (0.6%). CONCLUSIONS An outpatient clinic setup for patients with minor stroke/TIA yields shorter acute hospital stay, lower readmission rates, and better quality than hospitalization in stroke units. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that a neurovascular specialist-driven outpatient clinic for patients with minor stroke/TIA with the ability of subsequent admission is safe and yields shorter acute hospital stay, lower readmission rates, and better quality than hospitalization in stroke units.

Abstract
BACKGROUND Stroke prevalence is rising internationally. Advanced practice nursing is established across many jurisdictions; however, its contribution to stroke services is under research. AIM To gain insights into the future scope and role of future advanced nurse practitioners in stroke care from the perspectives of key stakeholders. DESIGN A qualitative descriptive approach. METHODS Interviews were conducted in 2019 with a purposive sample of 18 participants, comprising stroke nurses, stroke unit managers, stroke survivors and their family carers, recruited in one UK healthcare trust. The research is reported in line with COREQ. Data were analysed in accordance with an inductive content analysis approach. RESULTS The abstraction process generated four main themes. These were 'The lynchpin of the acute stroke service', 'An expert in stroke care', 'Person and family focussed' and 'Preparation for the role'. CONCLUSION These findings offer new perspectives on the potential scope and role of advanced nurse practitioners in stroke service delivery. Further research should focus on how to address the challenges confronted by advanced nurse practitioners when endeavouring to engage in autonomous clinical decision-making. IMPACT Study findings may advance postregistration education curricula, clinical supervision models and research directions. RELEVANCE TO CLINICAL PRACTICE There is support for the implementation of advanced practice nursing in the hyperacute and acute stroke phases of the care pathway. An interprofessional model of clinical supervision has potential to support the developing advanced nurse practitioner in autonomous clinical decision-making.

Abstract
Introduction Only a minority of patients with acute ischaemic stroke receive reperfusion treatment, primarily due to prehospital delay. We aimed to investigate predictors of a primary contact to the emergency medical services, arrival at stroke centre within 3 h of symptom onset and initiation of reperfusion therapy in patients with acute stroke. Patients and methods We conducted a cross-sectional study of consecutive patients with acute ischaemic stroke, intracerebral haemorrhage or transient ischaemic attack. Structured interviews of patients and bystanders were performed and combined with clinical information from the Danish Stroke Registry. Eligible patients were aged ≥18 years and were independent in activities of daily living before the stroke. Results We included 435 patients. Presence of a bystander at symptom onset and knowledge of ≥2 core symptoms of stroke were associated with a primary emergency medical services contact. Higher stroke severity and patients or bystanders perceiving the situation as very serious were associated with a primary emergency medical services contact (ORpatients 2.10; 95% CI 1.12-3.95 and ORbystanders 22.60; 95% CI 4.98-102.67), <3 h from onset to arrival (ORpatients 3.01; 95% CI 1.46-6.21 and ORbystanders 4.44; 95% CI 1.37-14.39) and initiation of reperfusion therapy (ORpatients 3.08; 95% CI 1.23-7.75 and ORbystanders 4.70; 95% CI 1.14-19.5).Conclusion: Having a bystander, knowledge of ≥2 core symptoms and understanding that stroke is a serious event are associated with appropriate help-seeking behaviour, shorter prehospital delay and higher chance of reperfusion therapy in acute stroke patients.

Abstract
BACKGROUND A bypass strategy for large vessel occlusion (LVO) benefits patients receiving endovascular thrombectomy (EVT), but may delay some patients from receiving IV thrombolysis. However, patient centralization has been shown to improve outcomes. OBJECTIVE To understand the current coverage of medical services for patients with stroke, and to identify the best coverage under different medical resource redistribution to help balance medical equality and patient centralization. METHODS This 6-year geographic study of 7679 on-scene patients with suspected stroke with a positive Cincinnati Prehospital Stroke Scale (CPSS) score identified 4037 patients with all three CPSS items who were suspected as having an LVO. Geographic, population, and patient coverage rates for hospitals providing IV thrombolysis and those providing EVT were identified according to hospital service areas, defined as geographic districts with access to a hospital within a ≤15 min off-peak driving time estimated using Google Maps. Moreover, we estimated the effects on resource redistribution when implementing a bypass strategy. RESULTS Geographic coverage rates for hospitals providing IV thrombolysis and those providing EVT were 64.75% and 56.62%, respectively, and population coverage rates were 97.30% and 92.72%, respectively. The service areas of hospitals providing IV thrombolysis covered 93.77% of patients with suspected stroke, and those of hospitals providing EVT covered 87.89% of patients with suspected LVO. The number of hospitals providing IV thrombolysis and those providing EVT could be reduced to six and two hospitals, respectively, without affecting hospital arrival time when implementing a bypass strategy. CONCLUSION Hospitals providing IV thrombolysis and EVT could be reduced without reducing medical equality.

Abstract
OBJECTIVES To investigate whether further centralisation of acute stroke services in Greater Manchester in 2015 was associated with changes in outcomes and whether the effects of centralisation of acute stroke services in London in 2010 were sustained. DESIGN Retrospective analyses of patient level data from the Hospital Episode Statistics (HES) database linked to mortality data from the Office for National Statistics, and the Sentinel Stroke National Audit Programme (SSNAP). SETTING Acute stroke services in Greater Manchester and London, England. PARTICIPANTS 509 182 stroke patients in HES living in urban areas admitted between January 2008 and March 2016; 218 120 stroke patients in SSNAP between April 2013 and March 2016. INTERVENTIONS Hub and spoke models for acute stroke care. MAIN OUTCOME MEASURES Mortality at 90 days after hospital admission; length of acute hospital stay; treatment in a hyperacute stroke unit; 19 evidence based clinical interventions. RESULTS In Greater Manchester, borderline evidence suggested that risk adjusted mortality at 90 days declined overall; a significant decline in mortality was seen among patients treated at a hyperacute stroke unit (difference-in-differences -1.8% (95% confidence interval -3.4 to -0.2)), indicating 69 fewer deaths per year. A significant decline was seen in risk adjusted length of acute hospital stay overall (-1.5 (-2.5 to -0.4) days; P<0.01), indicating 6750 fewer bed days a year. The number of patients treated in a hyperacute stroke unit increased from 39% in 2010-12 to 86% in 2015/16. In London, the 90 day mortality rate was sustained (P>0.05), length of hospital stay declined (P<0.01), and more than 90% of patients were treated in a hyperacute stroke unit. Achievement of evidence based clinical interventions generally remained constant or improved in both areas. CONCLUSIONS Centralised models of acute stroke care, in which all stroke patients receive hyperacute care, can reduce mortality and length of acute hospital stay and improve provision of evidence based clinical interventions. Effects can be sustained over time.
