Impact and sustainability of centralising acute stroke services in English metropolitan areas: retrospective analysis of hospital episode statistics and stroke national audit data

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.

ObjectiveTo investigate the effects of centralizing the acute stroke services in the Central Denmark Region (CDR).MethodsThe CDR (1.3 million inhabitants) centralized acute stroke care from 6 to 2 designated acute stroke units with 7-day outpatient clinics. We performed a prospective “before-and-after” cohort study comparing all strokes from the CDR with strokes in the rest of Denmark to discover underlying general trends, adopting a difference-in-differences approach. The population comprised 22,141 stroke cases hospitalized from May 2011 to April 2012 and May 2013 to April 2014.ResultsCentralization was associated with a significant reduction in length of acute hospital stay from a median of 5 to 2 days with a length-of-stay ratio of 0.53 (95% confidence interval 0.38–0.75, data adjusted) with no corresponding change seen in the rest of Denmark. Similarly, centralization led to a significant increase in strokes with same-day admission (mainly outpatients), whereas this remained unchanged in the rest of Denmark. We observed a significant improvement in quality of care captured in 11 process performance measures in both the CDR and the rest of Denmark. Centralization was associated with a nonsignificant increase in thrombolysis rate. We observed a slight increase in readmissions at day 30, but this was not significantly different from the general trend. Mortality at days 30 and 365 remained unchanged, as in the rest of Denmark.ConclusionsCentralizing acute stroke care in the CDR significantly reduced the length of acute hospital stay without compromising quality. Readmissions and mortality stayed comparable to the rest of Denmark.

ObjectivesThe policy of centralising hyperacute stroke units (HASUs) in England aims to provide stroke care in units that are both large enough to sustain expertise (>600 admissions/year) and dispersed enough to rapidly deliver time-critical treatments (<30 min maximum travel time). Currently, just over half (56%) of patients with stroke access care in such a unit. We sought to model national configurations of HASUs that would optimise both institutional size and geographical access to stroke care, to maximise the population benefit from the centralisation of stroke care.DesignModelling of the effect of the national reconfiguration of stroke services. Optimal solutions were identified using a heuristic genetic algorithm.Setting127 acute stroke services in England, serving a population of 54 million people.Participants238 887 emergency admissions with acute stroke over a 3-year period (2013–2015).InterventionModelled reconfigurations of HASUs optimised for institutional size and geographical access.Main outcome measureTravel distances and times to HASUs, proportion of patients attending a HASU with at least 600 admissions per year, and minimum and maximum HASU admissions.ResultsSolutions were identified with 75–85 HASUs with annual stroke admissions in the range of 600–2000, which achieve up to 82% of patients attending a stroke unit within 30 min estimated travel time (with at least 95% and 98% of the patients being within 45 and 60 min travel time, respectively).ConclusionsThe reconfiguration of hyperacute stroke services in England could lead to all patients being treated in a HASU with between 600 and 2000 admissions per year. However, the proportion of patients within 30 min of a HASU would fall from over 90% to 80%–82%.

Triage Time

Background: The Brant Community Healthcare System (BCHS) has consistently been well above the recommended 30 minute benchmark for door-to-needle (DTN) for eligible acute stroke patients. As a large community hospital with no neurologists, and like many other hospitals internationally, we rely on telestroke support for every stroke case. This is a time-consuming process that requires a multitude of phone calls, and pulls physicians from other acutely ill patients. We sought to develop a system that would streamline our approach and care for hyperacute stroke patients by targeting improvements in DTN. Aim Statement: We will decrease the door-to-needle (DTN) time for stroke patients arriving at the BCHS Emergency Department (ED) who are eligible for tissue plasminogen activator (tPA) by 25% from a median of 87 minutes to 50 minutes by March 31, 2018 and maintain that standard. Measures & Design: Outcome Measures: Door-to-needle time for acute stroke patients receiving tPA Process Measures: Door-to-triage time, Door-to-CT time, Door-to-CTA time; INR collection-to-verification time, telestroke callback time Balancing Measures: Number of stroke protocol patients per month Model Design: We simultaneously designed and implemented a robust program to train physician assistants in hyperacute stroke care. Evaluation/Results: Through vast stakeholder engagement and implementing a multitude of change ideas, by March of 2018 we had achieved an average DTN of 53 minutes. Our door-to-triage time went from an average of 7 minutes to 3 minutes. Our door-to-CT time decreased from 17 minutes to 7 minutes and our time between CT and CTA from an average of 13 minutes to 3 minutes. One and a half years later, our average DTN is maintained at 55 minutes and physician assistants continue to effectively lead and liaise with telestroke neurologists and stroke patients. Discussion/Impact: Prior to this program, acute stroke care was a very contentious topic at our local community hospital. Creating a program that streamlined the care and standardized the work has proven successful, and not only allowed for improved DTN times but also freed up physicians to better simultaneously care for other acutely ill patients.

ObjectiveTo investigate variations in quality of acute stroke care and outcomes by day and time of admission in London hyperacute stroke units compared with the rest of England.DesignProspective cohort study using anonymised patient-level data from the Sentinel Stroke National Audit Programme.SettingAcute stroke services in London hyperacute stroke units and the rest of England.Participants68 239 patients with a primary diagnosis of stroke admitted between January and December 2014.InterventionsHub-and-spoke model for care of suspected acute stroke patients in London with performance standards designed to deliver uniform access to high-quality hyperacute stroke unit care across the week.Main outcome measures16 indicators of quality of acute stroke care, mortality at 3 days after admission to the hospital, disability at the end of the inpatient spell, length of stay.ResultsThere was no variation in quality of care by day and time of admission to the hospital across the week in terms of stroke nursing assessment, brain scanning and thrombolysis in London hyperacute stroke units, nor was there variation in 3-day mortality or disability at hospital discharge (all p values>0.05). Other quality of care measures significantly varied by day and time of admission across the week in London (all p values<0.01). In the rest of England there was variation in all measures by day and time of admission across the week (all p values<0.01), except for mortality at 3 days (p value>0.05).ConclusionsThe London hyperacute stroke unit model achieved performance standards for ‘front door’ stroke care across the week. The same benefits were not achieved by other models of care in the rest of England. There was no weekend effect for mortality in London or the rest of the England. Other aspects of care were not constant across the week in London hyperacute stroke units, indicating some performance standards were perceived to be more important than others.

AbstractBackgroundWith the proposed pathophysiologic mechanism of neurologic injury by SARS COV-2 the frequency of stroke and henceforth the related hospital admissions were expected to rise. In this paper we investigate this presumption by comparing the frequency of admissions of stroke cases in Bangladesh before and during the pandemic.MethodsWe conducted a retrospective analysis of stroke admissions in a 100-bed stroke unit at the National Institute of Neurosciences and Hospital (NINS&H) which is considerably a large stroke unit. We considered all the admitted cases from the 1st January to the 30th June, 2020. We used Poisson regressions to determine whether statistically significant changes in admission counts can be found before and after 25 March since when there is a surge in COVID-19 infections.ResultsA total of 1394 stroke patients got admitted during the study period. Half of the patients were older than 60 years, whereas only 2.6% were 30 years old or younger with a male-female ratio of 1.06:1. From January to March, 2020 the mean rate of admission was 302.3 cases per month which dropped to 162.3 cases per month from April to June with an overall reduction of 46.3% in acute stroke admission per month. In those two periods, reductions in average admission per month for ischemic stroke (IST), intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH) and venous stroke (VS) were 45.5%, 37.2%, 71.4% and 39.0%, respectively. Based on weekly data, results of Poisson regressions confirm that the average number of admissions per week dropped significantly during the last three months of the sample period. Further, in the first three months, a total of 22 cases of hyperacute stroke management were done whereas in the last three months there was an 86.4% reduction in the number of hyperacute stroke patients getting reperfusion treatment. Only 38 patients (2.7%) were later found to be RT- PCR for SARS Cov-2 positive based on nasal swab testing.ConclusionOur study revealed more than fifty percent reduction in acute stroke admission during the COVID-19 pandemic. It is still elusive whether the reduction is related to the fear of getting infected by COVID-19 from hospitalization or the overall restriction on public movement and stay-home measures.

Background Thrombolysis treatment varies considerably between in- and out-of-hours services. Aims This improvement initiative aimed to upskill acute stroke unit nurses as stroke thrombolysis response nurses, testing a new model of nursing in readiness for hyperacute stroke unit developments. Methods Three registered nurses were trained to a specialist competency framework. The role was tested over 28 weeks, and times to treatment milestones were measured. Thrombolysed patients from the test period were statistically compared with a matched group using a two-sample t-test in Excel. Qualitative feedback was sought from the stroke team, medical and emergency department colleagues. Findings Median out-of-hours door-to-needle time reduced from 85 to 61.5 minutes. Statistically significant differences were seen in the time to stroke unit admission (p=0.012) and swallow screen (p=0.038). Stroke and emergency department colleagues considered the role essential to out-of-hours thrombolysis treatment. Conclusions The stroke thrombolysis response nurse role reduced variation in treatment and improved timely acute stroke care. This work may inform the development of stroke nursing workforce models.

Introduction: In 2012 a centralization and specialization of stroke services was implemented in Central Region Denmark (CRD) (n= 1.3 million inhabitants). It implied that acute stroke care was to be provided at only 2 units with re-vascularization therapy. Objective: The impacts on length of acute hospital stay (AHS), rate of thrombolysis (IV tPA), evidence-based clinical care and mortality. Methods: Population-based before-and-after registry study. The study cohort included all stroke cases in Denmark, with patients outside CRD being used as comparison to account for general changes in stroke care. The period before (May 2011- April 2012) was compared to after (May 2013 - April 2014) using regression methods, including difference-in-differences (DID) analysis. Potential confounders included age, gender, civil status, previous strokes, diabetes, atrial fibrillation, smoking, alcohol, stroke severity, hypertension and type of stroke. Results: Baseline data in Figure 1. Median length of AHS (days) in CRD decreased from 5 (IQR 7) to 2 (3) vs. from 5 (9) to 5 (8) in the rest of Denmark. IV tPA rates increased from 16% (95CI 14-17) to 19% (17-21) of all acute ischemic strokes in CRD and from 9% (8-10) to 14% (13-15) in the rest of Denmark (DID RR 0.77 (0.66-0.91)). All-or-none rates of 11 process performance measures of in-hospital care increased from 51% (49-53) to 63% (61-65) in CRD vs. 49% (48-50) to 60% (59-61) in the rest of Denmark (DID RR 0.99 (0.93-1.05)). Adjusted 30-days mortality rate decreased non-significantly and comparable to the rest of the country; OR 0.97 (0.71-1.32) vs. OR 0.91 (0.77-1.07) (DID OR 1.03 (0.75-1.41)). Conclusions: Centralization of acute stroke care was associated with a significant reduction in length of AHS when compared to the development in the rest of Denmark. The use of IV tPA and the quality of acute stroke care also improved, but the trend was not different from the rest of Denmark. No changes in the adjusted 30-days mortality were observed.

Background/Objective: There is growing importance on discovering factors that delay time to intervention for acute ischemic stroke (AIS) patients, as rapid intervention remains essential for better patient outcomes. The management of these patients involves a multidisciplinary effort and quality improvement initiatives to safely increase treatment with intravenous thrombolytic (IV tPa). The objective of this pilot is to evaluate factors of acute stroke care in the emergency department (ED) and the impact they have on IV tPa administration. Methods: A sample of 89 acute ischemic stroke patients that received IV tPa from a single academic medical institution was selected for retrospective analysis. System characteristics (presence of a stroke nurse and time of day) and patient characteristics (mode of arrival and National Institutes of Health Stroke Scale score (NIHSS) on arrival) were analyzed using descriptive statistics and multiple regression to address the study question. Results: The mean door to needle time is 53.74 minutes ( + 38.06) with 74.2% of patients arriving to the ED via emergency medical services (EMS) and 25.8% having a stroke nurse present during IV tPa administration. Mode of arrival ( p = .001) and having a stroke nurse present ( p = .022) are significant predictors of door to needle time in the emergency department (ED). Conclusion: While many factors can influence door to needle times in the ED, we did not find NIHSS on arrival or time of day to be significant factors. Patients arriving to the ED by personal vehicle will have a significant delay in IV tPa administration, therefore emphasizing the importance of using EMS. Perhaps more importantly, collaborative efforts including the addition of a specialized stroke nurse significantly decreased time to IV tPa administration for AIS patients. With this dedicated role, accelerated triage and more effective management of AIS patients is accomplished, leading to decreased intervention times and potentially improving patient outcomes.
