Variation in quality of acute stroke care by day and time of admission: prospective cohort study of weekday and weekend centralised hyperacute stroke unit care and non-centralised services

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.

Background Seven-day working in hospitals is a current priority of international health research and policy. Previous research has shown variability in delivering evidence-based clinical interventions across different times of the day and week. We aimed to identify factors influencing such variations in London hyperacute stroke units. Objectives To investigate variations in quality of acute stroke care and outcomes by day and time of admission in London hyperacute stroke units, and to identify factors influencing such variations. Design This was a prospective cohort study using anonymised patient-level data from the Sentinel Stroke National Audit Programme. Factors influencing variations in care and outcomes were studied through interview and observation data. Setting The setting was acute stroke services in London hyperacute stroke units. Participants A total of 7094 patients with a primary diagnosis of stroke took part. We interviewed hyperacute stroke unit staff (n = 76), including doctors, nurses, therapists and administrators, and 31 patients and carers. We also conducted non-participant observations of delivery of care at different times of the day and week (n = 45, ≈102 hours). Intervention Hub-and-spoke model for care of suspected acute stroke patients in London with performance standards was designed to deliver uniform access to high-quality hyperacute stroke unit care across the week. Main outcome measures Indicators of quality of acute stroke care, mortality at 3 days after admission, disability at the end of the inpatient spell and length of stay. Data sources Sentinel Stroke National Audit Programme data for all patients in London hyperacute stroke units with a primary diagnosis of stroke between 1 January and 31 December 2014, and nurse staffing data for all eight London hyperacute stroke units for the same period. Results We found no variation in quality of care by day and time of admission across the week in terms of stroke nursing assessment, brain scanning and thrombolysis in London hyperacute stroke units, nor in 3-day mortality nor disability at hospital discharge. Other quality-of-care measures significantly varied by day and time of admission. Quality of care was better if the nurse in charge was at a higher band and/or there were more nurses on duty. Staff deliver ‘front-door’ interventions consistently by taking on additional responsibilities out of hours, creating continuities between day and night, building trusting relationships and prioritising ‘front-door’ interventions. Limitations We were unable to measure long-term outcomes as our request to the Sentinel Stroke National Audit Programme, the Healthcare Quality Improvement Partnership and NHS Digital for Sentinel Stroke National Audit Programme data linked with patient mortality status was not fulfilled. Conclusions Organisational factors influence 24 hours a day, 7 days a week (24/7), provision of stroke care, creating temporal patterns of provision reflected in patient outcomes, including mortality, length of stay and functional independence. Future work Further research would help to explore 24/7 stroke systems in other contexts. We need a clearer understanding of variations by looking at absolute time intervals, rather than achievement of targets. Research is needed with longer-term mortality and modified Rankin Scale data, and a more meaningful range of outcomes.

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.

Introduction: There have been few reports on status of acute stroke management at a national level worldwide, and none in Korea. This study is aimed to describe the current status and disparities of acute stroke management in Korea. Methods: Data from 5th (2013) and 6th (2014) national surveys for assessing quality of acute stroke care were used. Patients with principal diagnosis codes indicating subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), ischemic stroke (IS), who were admitted via emergency rooms within 7 days of onset at hospitals treating 10 or more stroke cases during the each 3-month survey period were selected. Results: A total of 19,608 stroke cases (age, 67.7±13.5years; female, 45%; IS, 76%; ICH, 15%; SAH, 9%) treated in 216 hospitals were analyzed. Thirty-one percent of hospitals had stroke units and 41% of stroke cases were treated at hospitals without stroke units. In IS, IV thrombolysis (IVT) and endovascular treatment (EVT) rates were 10.7% and 3.6%, respectively. Thirty-nine percent of IVT and fifty-two percent of EVT cases were performed in hospitals with annual volume of <25 IVT and <15 EVT. Centralization of EVT showed disparities by region (Figure). Carotid endarterectomy, carotid artery stenting, decompressive, bypass surgery was conducted in 0.2%, 1.4%, 1.0%, 0.2% of IS cases; decompressive surgery was done in 28.1% of ICH cases; surgical clipping, endovascular coiling was done in 17.2%, 14.3% of SAH cases, respectively. There were noticeable regional disparities in various interventions, use of ambulance, arrival time and provision of stroke unit service. Conclusions: This study is the first report on the status of acute stroke care in Korea on a national level. Large number of recanalization therapies were performed in low-volume-hospitals. Expansion of stroke unit service, stroke center certification or accreditation, and connections between stroke centers and EMS are highly recommended.

Stroke Thrombolysis

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.

Mean Time

Background: Primary Stroke Centers (PSC) provide better acute stroke care than non-PSC hospitals, including faster times to imaging and lytic treatment, and higher rates of lytic delivery. Nationwide less than 1 in 3 hospital has achieved this designation. We aimed to determine the extent to which the better performance at PSC is driven by improvements within hospitals after PSC designation versus better baseline hospital care among facilities seeking PSC certification. Methods: From 2005 to 2012, the NIH Field Administration of Stroke Therapy -Magnesium (FAST-MAG) Phase 3 clinical trial enrolled subjects with likely stroke within 2 hours of onset in a study of prehospital start of a neuroprotective agent. Subjects were routed to 59 community and academic centers in Los Angeles and Orange Counties. Of the original 59 centers, 39 eventually achieved PSC status during the study period. Each subject was classified as enrolled at a PSC before certification (pre-PSC), at a PSC post certification (post-PSC), or at a hospital that never achieved PSC (non-PSC). Results: Of 1700 cases, 529 (31%) were enrolled at pre-PSC, 856 (50%) at post-PSC, and 315 (19%) at non-PSC hospitals. Mean time in minutes from ED arrival to first scan was 33 minutes at post-PSC, 47 minutes at pre-PSC and 49 at non-PSCs [p<0.001 by Mann-Whitney]. Among cases of cerebral ischemia (CI) [N=1223], rates of TPA utilization were 43% at post-PSC, 27% at pre-PSC and 28% at non-PSC hospitals [p<0.001 by X2]. Time in minutes from ED arrival to thrombolysis in treated cases was 71 at post-PSC, 98 at pre-PSC, and 95 at non-PSC hospitals [p<0.001 by Mann-Whitney]. Hospitals that achieved PSC showed improvements in pre-PSC and post-PSC performance on door to imaging time, from 47 to 33 minutes [p=0.014]; percent TPA use in CI, from 27% to 43% [p<0.001], and reduced door-to-needle times, from 98 to 71 minutes [p=0.003]. There was no difference in time to imaging [47 vs. 49 minutes], time to thrombolysis [98 vs. 95 minutes] and percent TPA use [27% vs. 28%] between pre-PSC hospitals and non-PSC hospitals. Conclusions: Better performance of Primary Stroke Centers on acute care quality metrics is primarily driven by a beneficial impact of the PSC-certification process, and not better performance prior to seeking PSC status.

Over Time

Background and Purpose: Rapid access to acute stroke treatment improves clinical outcomes in patients with ischemic stroke. We aimed to shorten the time to admission and to acute stroke treatment for patients with acute stroke in the Hamburg metropolitan area by collaborative multilevel measures involving all hospitals with stroke units, the Emergency Medical Services (EMS), and health-care authorities. Methods: In 2007, an area-wide stroke care quality project was initiated. The project included mandatory admission of all stroke patients in Hamburg exclusively to hospitals with stroke units, harmonized acute treatment algorithms among all hospitals, repeated training of the EMS staff, a multimedia educational campaign, and a mandatory stroke care quality monitoring system based on structured data assessment and quality indicators for procedural measures. We analyzed data of all patients with acute stroke who received inhospital treatment in the city of Hamburg during the evaluation period from the quality assurance database data and evaluated trends of key quality indicators over time. Results: From 2007 to 2016, a total of 83,395 patients with acute stroke were registered. During this period, the proportion of patients admitted within ≤3 h from symptom onset increased over time from 27.8% in 2007 to 35.2% in 2016 (p < 0.001). The proportion of patients who received rapid thrombolysis (within ≤30 min after admission) increased from 7.7 to 54.1% (p < 0.001). Conclusions: Collaborative stroke care quality projects are suitable and effective to improve acute stroke care.

Abstract Cardiologists need a better understanding of stroke and of cardiac implications in modern stroke management. Stroke is a leading disease in terms of mortality and disability in our society. Up to half of ischaemic strokes are directly related to cardiac and large artery diseases and cardiovascular risk factors are involved in most other strokes. Moreover, in an acute stroke direct central brain signals and a consecutive autonomic/vegetative imbalance may account for severe and life-threatening cardiovascular complications. The strong cerebro-cardiac link in acute stroke has recently been addressed as the stroke-heart syndrome that requires careful cardiovascular monitoring and immediate therapeutic measures. The regular involvement of cardiologic expertise in daily work on a stroke unit is therefore of high importance and a cornerstone of up-to-date comprehensive stroke care concepts. The main targets of the cardiologists’ contribution to acute stroke care can be categorized in three main areas (i) diagnostics workup of stroke aetiology, (ii) treatment and prevention of complications, and (iii) secondary prevention and sub-acute workup of cardiovascular comorbidity. All three aspects are by themselves highly relevant to support optimal acute management and to improve the short-term and long-term outcomes of patients. In this article, an overview is provided on these main targets of cardiologists’ contribution to acute stroke management.

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%.
