Utstein recommendation for emergency stroke care.

BACKGROUND: Recent advances in treatment for stroke give new possibilities for optimizing outcomes. To deliver these prehospital care needs to become more efficient. AIM: To develop a framework to support improved delivery of prehospital care. The recommendations are aimed at clinicians involved in prehospital and emergency health systems who will often not be stroke specialists but need clear guidance as to how to develop and deliver safe and effective care for acute stroke patients. METHODS: Building on the successful implementation program from the Global Resuscitation Alliance and the Resuscitation Academy, the Utstein methodology was used to define a generic chain of survival for Emergency Stroke Care by assembling international expertise in Stroke and Emergency Medical Services (EMS). Ten programs were identified for Acute Stroke Care to improve survival and outcomes, with recommendations for implementation of best practice. CONCLUSIONS: Efficient prehospital systems for acute stroke will be improved through public awareness, optimized prehospital triage and timely diagnostics, and quick and equitable access to acute treatments. Documentation, use of metrics and transparency will help to build a culture of excellence and accountability.

Sex differences in trajectories of depression symptoms and associations with 10-year mortality in patients with stroke: the South London Stroke Register.

BACKGROUND AND PURPOSE: Depression is a common neuropsychiatric consequence of stroke. We identified trajectories of depression symptoms in men and women and examined their associations with 10-year all-cause mortality. METHODS: Data were obtained from the South London Stroke Register (1998-2016). Socio-demographic, stroke severity and clinical measures were collected during the acute phase. The Hospital Anxiety and Depression Scale was used to screen for depression at 3 months after stroke and then annually. We used group-based trajectory models to identify trajectories of depression and Cox proportional hazards models to study the risk of mortality in them. RESULTS: We studied 1275 men and 1038 women. Three trajectories of depression symptoms were identified in men: I-M (42.12%), low and stable symptoms; II-M (46.51%), moderate increasing symptoms; and III-M (11.37%), severe persistent symptoms. Four trajectories were identified in women; I-F (29.09%), low symptoms; II-F (49.81%), moderate symptoms; III-F (16.28%), severe symptoms; and IV-F (4.82%), very severe symptoms, all with stable symptoms. The 10-year adjusted mortality hazard ratios in men were: 1.68 [95% confidence interval (CI), 1.38-2.04] and 2.62 (95% CI, 1.97-3.48) for trajectories II-M and III-M, respectively, compared with I-M. In women these were: 1.38 (95% CI, 1.09-1.75), 1.65 (95% CI, 1.23-2.20) and 2.81 (95% CI, 1.90-4.16) for trajectories II-F, III-F and IV-F, respectively, compared with I-F. CONCLUSIONS: Depression trajectories varied independent of sex. Severe symptoms in women were double those in men. Moderate symptoms in men became worse over time. Increased symptoms of depression were associated with higher mortality rates. Data on symptom progression may help a better long-term management of patients with stroke.

The long-term outcomes of depression up to 10 years after stroke; the South London Stroke Register.

BACKGROUND: Post-stroke depression is a frequent chronic and recurrent problem that starts shortly after stroke and affects patients in the long term. The health outcomes of depression after stroke are unclear. AIMS: (1) To investigate the associations between depression at 3 months and mortality, stroke recurrence, disability, cognitive impairment, anxiety and quality of life (QoL), up to 5 years post-stroke. (2) To investigate these associations in patients recovering from depression by year 1. (3) To investigate associations between depression at 5 years and these outcomes up to 10 years. METHODS: Data from the South London Stroke Register (1997-2010) were used. Patients (n at registration=3240) were assessed at stroke onset, 3 months after stroke and annually thereafter. Baseline data included sociodemographics and stroke severity measures. Follow-up assessments included anxiety and depression (Hospital Anxiety and Depression scale), disability, QoL and stroke recurrence. Multivariable regression models adjusted for age, gender, ethnicity, stroke severity and disability were used to investigate the association between depression and outcomes at follow-up. RESULTS: Depression at 3 months was associated with: increased mortality (HR: 1.27 (1.04 to 1.55)), disability (RRs up to 4.71 (2.96 to 7.48)), anxiety (ORs up to 3.49 (1.71 to 7.12)) and lower QoL (coefficients up to -8.16 (-10.23-6.15)) up to year 5. Recovery from depression by 1 year did not alter these risks to 5 years. Depression in year 5 was associated with anxiety (ORs up to 4.06 (1.92 to 8.58)) and QoL (coefficients up to -11.36 (-14.86 to -7.85)) up to year 10. CONCLUSIONS: Depression is independently associated with poor health outcomes.

Current practice of carotid endarterectomy in the UK.

BACKGROUND: Carotid endarterectomy (CEA) reduces the risk of stroke in patients with internal carotid stenosis of 50-99 per cent. This study assessed national surgical practice through audit of CEA procedures and outcomes. METHODS: This was a prospective cohort study of UK surgeons performing CEA, using clinical audit data collected continuously and reported in two rounds, covering operations from December 2005 to December 2007, and January 2008 to September 2009. RESULTS: Some 352 (92·6 per cent) of 380 eligible surgeons contributed data. Of 19,935 CEAs recorded by Hospital Episode Statistics, 12,496 (62·7 per cent) were submitted to the audit. A total of 10,452 operations (83·6 per cent) were performed for symptomatic carotid stenosis; among these patients, the presenting symptoms were transient ischaemic attack in 4507 (43·1 per cent), stroke in 3572 (34·2 per cent) and amaurosis fugax in 1965 (18·8 per cent). The 30-day mortality rate was 1·0 per cent (48 of 4944) in round 1 and 0·8 per cent (50 of 6151) in round 2; the most common cause of death was stroke, followed by myocardial infarction. The rate of death or stroke within 30 days of surgery was 2·5 per cent (124 of 4918) in round 1 and 1·8 per cent (112 of 6135) in round 2. CONCLUSION: CEA is performed less commonly in the UK than in other European countries and probably remains underutilized in the prevention of stroke. Increasing the number of CEAs done in the UK, together with reducing surgical waiting times, could prevent more strokes.

Stroke thrombolysis in England, Wales and Northern Ireland: how much do we do and how much do we need?

BACKGROUND: Data are limited on the proportion of stroke patients nationally appropriate for thrombolysis either within the 3 h time window or the recently tested 4.5 h. This information is important for the redesign of services. METHODS: Data on case mix, eligibility for thrombolysis, treatment and outcomes were extracted from the National Sentinel Stroke 2008 Audit dataset. This contains retrospective data on up to 60 consecutive stroke admissions from each acute hospital in England, Wales and Northern Ireland between 1 April and 30 June 2008. FINDINGS: All relevant hospitals participated, submitting data on 11,262 acute stroke patients. 2118 patients arrived within 2 h and 2596 within 3 h of the onset of symptoms and 587 people were already in hospital. Therefore, 28% (3183) were potentially eligible for thrombolysis based on a 3 h time criterion. Of these, 1914 were under 80 years and 2632 had infarction with 14% (1605) meeting all three National Institute of Neurological Disorders and Stroke study criteria and so being potentially eligible for thrombolysis. If the time window is increased to 4.5 h then only another 2% became eligible. If the age limit was removed for treatment, the percentage potentially appropriate for tissue plasminogen activator increased to 23% within 3 h and 26% within 4.5 h. Overall, 1.4% (160) of patients were thrombolysed. INTERPRETATION: Thrombolysis rates are currently low in the UK. 14% of patients in this sample were potentially suitable for thrombolysis using the 3 h time window. This would only increase marginally if thrombolysis was extended to include those up to 4.5 h. The greatest impact on increasing the proportion of patients suitable for thrombolysis would be to increase the number of patients presenting early and by demonstrating that the treatment is safe and effective in patients over 80 years of age.

Patient-specific recovery patterns over time measured by dependence in activities of daily living after stroke and post-stroke care: the South London Stroke Register (SLSR).

BACKGROUND AND PURPOSE: Data on patient-specific recovery after stroke are lacking and the effects of complex healthcare interventions on the course of recovery were not reported. To quantify the recovery pattern up to 1 year post-stroke and assess effects of evidence-based treatments on the patient-specific course of recovery allowing its prediction. METHODS: A total of 355 patients after first-ever stroke from the population-based South London Stroke Register (source population >270,000) participated in a substudy between August 2002 and October 2004. At 1, 2, 3, 4, 6, 8, 12, 26, and 52 weeks post-stroke, Barthel Index (BI; ranging from 0 to 20) was documented. Multilevel growth models allowing predictions for patients with specific characteristics were calculated. RESULTS: Mean age was 70 years, 48% were male and 23% died within the first year. The age-, gender- and stroke subtype-adjusted BI curve sharply increased until week 8 to 24 depending on patient characteristics and subsequently plateaued. Multivariable analysis identified stroke unit care, appropriate secondary prevention and physiotherapy for those with disabilities as independent predictors of improved functional ability over time (P < 0.05). Patients receiving stroke unit care additionally gained 4 BI points within 6 months compared with their counterparts (P = 0.004). CONCLUSIONS: Functional outcome in the general population showed an increase followed by a plateau. Care parameters reflecting guideline treatment independently improved recovery illustrating the beneficial effects of evidence-based interventions on recovery in an unbiased population.

An observational study of acute stroke care in four countries: the European registers of stroke study.

BACKGROUND: The European Registers Of Stroke (EROS) project aimed to assess outcomes of stroke care across Europe, relating these to both case mix information from disease-specific population registers and the quality of stroke care provided at each centre. This included comparing information on quality of care with direct observation of the stroke care process in 4 centres. METHODS: Direct non-participant observational methods were used on a purposive sample of first-stroke patients admitted within the past 14 days to an acute-stroke unit or ward that admits stroke patients in 4 urban hospital sites in London, UK, Dijon, France, Kaunas, Lithuania, and St. Petersburg, Russia. We recorded patient characteristics with levels of contact with multi-disciplinary team (MDT) members and contact with families and mobilization to build a collection of 'snapshots' of stroke care throughout the patients' day. One independent observer undertook all observations over 1 day. RESULTS: We observed differences between centres in the proportion of observations where patients were alone (lowest proportion in London, highest proportion in St. Petersburg) (p > 0.001), where patients had contact with MDT members (p > 0.001) and family, and where patients were out of bed/mobile (p > 0.001) (both with highest proportion in London, lowest proportion in St. Petersburg). CONCLUSIONS: Higher levels of contact with the MDT, family contact and mobilization were observed in the Western European centres than the Eastern European and Russian centres. Differences in case mix may explain some, but not all, of these differences. Direct observation has some limitations; however, it could be developed in future studies to help identify other key aspects of effective stroke care.

Frequency and predictors for the risk of stroke recurrence up to 10 years after stroke: the South London Stroke Register.

BACKGROUND: Data estimating the risk of, and predictors for, long-term stroke recurrence are lacking. METHODS: Data were collected from the population-based South London Stroke Register. Patients were followed up for a maximum of 10 years. Kaplan-Meier estimates and Cox proportional hazards models were used to assess the cumulative risk of and predictors for first stroke recurrence. Variables analysed included sociodemographic factors, stroke subtype (defined as cerebral infarction, intracerebral haemorrhage and subarachnoid haemorrhage), stroke severity markers and prior-to-stroke risk factors. RESULTS: Between 1995 and 2004, 2874 patients with first-ever stroke were included. The mean follow-up period was 2.9 years. During 8311 person-years of follow-up, 303 recurrent events occurred. The cumulative risk of stroke recurrence at 1 year, 5 years and 10 years was 7.1%, 16.2% and 24.5% respectively. No differences in stroke recurrence were noted between the stroke subtypes. Factors increasing the risk of recurrence at 1 year were previous myocardial infarction (HR 1.73; 95% CI 1.08 to 2.78) and atrial fibrillation (HR 1.61; 95% CI 1.04 to 4.27); at 5 years, hypertension (HR 1.47; 95% CI 1.08 to 1.99) and atrial fibrillation (HR 1.79; 95% CI 1.29 to 2.49); and at 10 years, older age (p = 0.04), and hypertension (HR 1.38, 95% CI 1.04 to 1.82), myocardial infarction (HR 1.50, 95% CI 1.06 to 2.11) and atrial fibrillation (HR 1.51, 95% CI 1.09 to 2.09). CONCLUSIONS: Very-long-term risk of stroke recurrence is substantial. Different predictors for stroke recurrence were identified throughout the follow-up period. Risk factors prior to initial stroke have a significant role in predicting stroke recurrence up to 10 years.

Predictors of survival after haemorrhagic stroke in a multi-ethnic population: the South London Stroke Register (SLSR).

OBJECTIVES: To identify the predictors of long-term survival after haemorrhagic stroke. METHODS: Data were collected within the population-based South London Stroke Register covering a multiethnic source population of 271,817 inhabitants (2001) in South London. Death data were collected at post-stroke follow-up. The impact of patients' demographic and clinical characteristics, ethnic origin, pre-stroke risk factors and acute treatment on long-term survival were investigated. Survival methods included Kaplan-Meier curves and Cox's proportional hazards model. RESULTS: Between January 1995 and December 2004, a total of 566 patients with first-ever haemorrhagic stroke (395 primary intracerebral haemorrhage; 171 subarachnoid haemorrhage) were registered. Mean age was 62.3 years; 365 (64.5%) were white, 132 (23.3%) were black and 69 (12.2%) were other or unknown ethnic origin; there were 1340 person-years of follow-up. After multivariable adjustment, age (p<0.001) and having diabetes (hazard ratio (HR), 1.69; 95% CI 1.06-2.70) were associated with increased risk of death. Patients with severe stroke (Glasgow Coma Scale (GCS) <9) had an increased risk of death (HR 6.5; 95% CI 4.68 to 8.90) compared with those with mild stroke (GCS >12). Treatment on a stroke unit reduced the long-term risk of death (HR 0.70; 95% CI 0.50 to 0.98). Black patients had a reduced risk of death (HR 0.62; 95% CI 0.42 to 0.92) compared with white patients. CONCLUSIONS: Age, diabetes, stroke severity and stroke unit care influenced the long-term risk of death after haemorrhagic stroke. An independent survival advantage was observed in black patients. These factors can be utilised for clinical predictions but the cause of the observations in black patients remains unclear.

Comparison of patients' assessments of the quality of stroke care with audit findings.

OBJECTIVE: To determine the extent of correlation between stroke patients' experiences of hospital care with the quality of services assessed in a national audit. METHODS: Patients' assessments of their care derived from survey data were linked to data obtained in the National Sentinel Stroke Audit 2004 for 670 patients in 51 English NHS trusts. A measure of patients' experience of hospital stroke care was derived by summing responses to 31 survey items and grouping these into three broad concept domains: quality of care; information; and relationships with staff. Audit data were extracted from hospital admissions data and management information to assess the organisation of services, and obtained retrospectively from patient records to evaluate the delivery of care. Patient survey responses were compared with audit measures of organisation of care and compliance with clinical process standards. RESULTS: Patient experience scores were positively correlated with clinicians' assessment of the organisational quality of stroke care, but were largely unrelated to clinical process standards. Responses to individual questions regarding communication about diagnosis revealed a discrepancy between clinicians' and patients' reports. CONCLUSIONS: Better organised stroke care is associated with more positive patient experiences. Examining areas of disparity between patients' and clinicians' reports is important for understanding the complex nature of healthcare and for identifying areas for quality improvement. Future evaluations of the quality of stroke services should include a validated patient experience survey in addition to audit of clinical records.

Access to stroke care in England, Wales and Northern Ireland: the effect of age, gender and weekend admission.

STUDY OBJECTIVES: To determine whether access to high-quality stroke care is affected by the age or gender of the patient or by weekend admission. DESIGN: Data were collected as part of the National Sentinel Audit of stroke in 2004, both on the organisation of in-patient stroke care and the process of care to hospitals managing stroke patients. SETTING: Two hundred and forty-six hospitals from England, Wales and Northern Ireland took part in the 2004 National Stroke Audit, a response rate of 100%. These sites audited te care of 8,718 patients. AUDIT TOOL: Royal College of Physicians Intercollegiate Working Party Stroke Audit Tool. RESULTS: Overall standards of care for cases of stroke in England, Wales and Northern Ireland are low. Older patients are less likely to be treated in a stroke unit than younger patients (risk ratio comparing 85 + years with those <65 years 0.82 (95% CI 0.75-0.90). Seventy-one per cent of patients under 65 years were scanned within 24 h compared to 51% aged over 85 years. Older patients were also less likely than younger ones to receive secondary prevention and some aspects of rehabilitation, especially around higher functioning. Standards were consistently better for patients of all ages managed in stroke units compared to general wards. At weekends, patients were less likely to be admitted directly to a stroke unit (risk ratio 0.77 95% CI 0.69-0.86) and brain imaging was performed less often for older (85 + years) patients (weekday 56%, weekend 40%). There was little evidence of differences in standards of care between males and females. CONCLUSION: There is clear evidence of an age effect on the delivery of stroke care in England, Wales, and Northern Ireland, with older patients being less likely to receive care in line with current clinical guidelines. Quality of acute care is also less good for patients admitted at weekends. No systematic evidence for sexism was identified.

Variations in the use of diagnostic procedures after acute stroke in Europe: results from the BIOMED II study of stroke care.

Valid classification of stroke is essential to initiate effective acute management and early secondary prevention strategies. To accurately evaluate stroke subtype a number of diagnostic procedures have to be performed. This study sought to investigate variations in use of diagnostic procedures across selected European hospitals. First-ever stroke patients were sampled over a 1-year period through 11 hospital-based registers across 10 European countries. We defined a diagnostic standard for valid aetiological classification of ischemic stroke including brain imaging, vascular imaging and echocardiography. The impact of socio-demographic, clinical and structural characteristics on performance of the diagnostic standard was assessed using multivariate logistic regression analyses. A total of 1721 patients were included in the study. 83.1% received brain imaging, ranging from 32.8% to 100%. The diagnostic standard was performed in 40.4% of stroke patients, ranging from 0% to 77.2%. Patients with increasing age (P < 0.001) and with more severe strokes (P = 0.001) were less probably to receive the diagnostic standard. Patients treated in stroke units and neurological departments were more frequently investigated with the diagnostic standard (P < 0.001). Less than half of hospitalized stroke patients across Europe underwent diagnostic procedures to allow for aetiological classification of stroke, which may hamper the initiation of effective early management and secondary prevention.

Clinical determinants of long-term quality of life after stroke.

OBJECTIVES: To determine factors that independently predict health-related quality of life (HRQOL) 1 and 3 years after stroke. METHODS: Subjects numbering 397, from a population-based register of first-ever strokes were assessed for HRQOL using the Short Form 36 (SF36) 1 year after stroke. Physical (PHSS) and mental health (MHSS) summary scores were derived from the eight domains of HRQOL in the SF36. Multivariate stepwise regression analyses were conducted to determine independent predictors of these scores; beta coefficients with 95% CI were obtained.beta coefficient is the difference between average value of the variable (e.g. male) and average value under consideration (e.g. female). Demographic and stroke risk factors, neurological impairments and cognitive impairment (MMSE <24) were included in the models. Similar analyses were undertaken on 150 subjects 3 years post-stroke. RESULTS: A year after stroke, independent predictors of the worst PHSS were of females (beta coefficient -3.3: 95% CI -5.7 to -0.8), manual workers (-3.2: -5.9 to -0.4), diabetes (-4.2: -7.7 to -0.8), right hemispheric lesions (-4.9: -8.7 to -1.2), urinary incontinence (-7.8: -11.6 to -4.1) and cognitive impairment (-2.7: -5.5 to -0.1); the worst MHSS were associated with being Asian (-11.8: -20.6 to -3.0), ischaemic heart disease (-2.7: -5.4 to -0.03), cognitive impairment (-3.04: -5.8 to -0.3). Subjects aged 65-75 years (5.4: 2.5 to -8.4) had better MHSS than those <65 years. Three years post-stroke, independent predictors of worse PHSS were hypertension (-8.7: -13.5 to -3.9), urinary incontinence (-8.1: -15 to -1.1) and cognitive impairment (-8.3: -13.2 to -3.5). CONCLUSIONS: Determinants of HRQOL vary both over time after stroke and whether physical or psychosocial aspects of HRQOL are being considered. This study provides valuable information on factors predicting long-term HRQOL, which can be taken into consideration in audits of clinical practice or in future interventional studies aiming to improve HRQOL after stroke.

Relationships between long-term stroke disability, handicap and health-related quality of life.

OBJECTIVES: To estimate levels of disability, handicap and health-related quality of life (HRQOL) up to 3 years after stroke and examine the relationships between these domains. DESIGN: A longitudinal, observational study SETTING: Population-based register of first-ever strokes METHODS: Subjects, registered between 1 January 1995 and 31 December 1997, were assessed at 1 year (n = 490) and 3 years (n = 342) post-stroke for disability [Barthel index (BI)], handicap [Frenchay activity index (FAI)] and HRQOL (SF-36). BI was categorised as severe, moderate, mild and independent (0-9, 10-14, 15-19 and 20); FAI was categorised as inactive, moderately active and very active (0-15, 16-30 and 31-45). SF-36 domains include: Physical Functioning (PF), Role Physical (RP), Bodily Pain (BP), General Health (GH), Vitality (VT), Social Functioning (SF), Role Emotional (RE) and Mental Health (MH). Physical (PHSS) and Mental Health (MHSS) Summary Scores were computed. RESULTS: at 1 and 3 years, 26.1 and 26.3%, respectively, were disabled (BI < 15); 55 and 51%, respectively, were handicapped (FAI = 0-15); and survivors had low mean PHSS (37.1 and 37.9), but satisfactory mean MHSS (46.6 and 47.7). There was a graded positive relationship between all SF-36 domains and the categories of BI and FAI. Spearman rank correlations were significant between BI and all SF-36 domains at both time points: strong (r > 0.70) with PF, moderate (r = 0.31-0.70) with RP, SF and PHSS, but weak (r < 0.30) with other domains. Correlations between FAI and SF-36 domains were strong with PF, weak with BP, RE and MHSS, and moderate with other domains. CONCLUSIONS: Disability and handicap remain highly prevalent up to 3 years after stroke. Patients' perception of physical health is persistently low, but mental health perception is satisfactory up to 3 years. Due to variable correlations between different HRQOL domains with disability and handicap, it is suggested that disability, handicap and HRQOL should all be assessed to acquire a broader measure of stroke outcome.

Improving clinical practice in stroke through audit: results of three rounds of National Stroke Audit.

BACKGROUND: The results of three rounds of National Stroke Audit in England, Wales and Northern Ireland are compared. METHODS: Audit of the organization of stroke services and retrospective case-note audit of up to 40 consecutive cases admitted per hospital over a 3-month period was conducted in each of 1998, 1999 and 2001/02. The changes in the organizational, case-mix and process results of the hospitals that had participated in all three rounds were analysed. RESULTS: 60% of all eligible trusts from England, Wales and Northern Ireland took part in all three audits in 1998, 1999 and 2001/02. Total numbers of cases were 4996, 4841 and 5152, respectively. Case-mix variables were similar over the three rounds. Mortality at 7 and 30 days fell by 3% and 5%, respectively. The proportion of hospitals with a stroke unit rose from 48% to 77%. The proportion of patients spending most of their stay in a stroke unit rose from 17% in 1998 to 26% in 1999 and 29% in 2001/02. Improvements achieved in process standards of care between 1998 and 1999 (median change was a gain of 9%) failed to improve further by 2001/02 (median change was 0%). In all three rounds process standards of care tended to be better in stroke units. CONCLUSIONS: Three rounds of national audit of stroke care have shown standards of care on stroke units were notably higher than on general wards. Slowing in the rise of the proportion managed on stroke units mirrors the slow down in improvement to overall national standards of care. To further improve outcomes and national standards of stroke care a much higher proportion of patients needs to be managed in stroke units.

Institutionalization after stroke.

BACKGROUND AND PURPOSE: There are widespread regional variations in the institutionalization rate after stroke. This study sought to identify the factors that predict institutionalization after a primary diagnosis of stroke and determine whether institutionalization rate could be used to assess the quality of hospital care. METHODS: A retrospective case note audit of 2778 consecutive admissions with stroke, between 1 September and 31 October 2000 from a randomly selected sample of 79 hospitals in England, Wales and Northern Ireland. Data were collected on demographics, case-mix, clinical outcome, organization of discharge, and place of residence at discharge and at three and six months. The figures from this audit were validated using data from the 1998 National Sentinel Audit of Stroke. RESULTS: Overall 14% of patients previously living at home were discharged to nursing or residential homes. Using logistic regression, Barthel Index score at discharge accounted for 40% of variation. Two-thirds of patients with a discharge Barthel score of < 5 were institutionalized. Age alone explained 14% and when taken together with discharge Barthel and length of stay it accounted for 54% of variation. On admission 22% of the variation in institutionalization rate could be accounted for by total Glasgow Coma Score (15, < 15), age and ability to walk unaided. Regional variations in institutionalization rates are evident and may in part be explained by differences in ease of access to the institutions. CONCLUSIONS: Discharge disability and older age were the dominant factors determining admission to nursing and residential homes. It is not possible to predict sufficiently reliably for an individual patient the likelihood of institutionalization at admission or at 72 h after admission, to justify early resource allocation decisions.

Stroke units: research and reality. Results from the National Sentinel Audit of Stroke.

OBJECTIVES: To use data from the 2001-2 National Stroke Audit to describe the organisation of stroke units in England, Wales and Northern Ireland, and to see if key characteristics deemed effective from the research literature were present. DESIGN: Data were collected as part of the National Sentinel Audit of Stroke in 2001, both on the organisation and structure of inpatient stroke care and the process of care to hospitals managing stroke patients. SETTING: 240 hospitals from England, Wales and Northern Ireland took part in the 2001-2 National Stroke Audit, a response rate of over 95%. These sites audited a total of 8200 patients. AUDIT TOOL: Royal College of Physicians Intercollegiate Working Party Stroke Audit Tool. RESULTS: 73% of hospitals participating in the audit had a stroke unit but only 36% of stroke admissions spent any time on one. Only 46% of all units describing themselves as stroke units had all five organisational characteristics that previous research literature had identified as being key features, while 26% had four and 28% had three or less. Better organisation was associated with better process of care for patients, with patients managed on stroke units receiving better care than those managed in other settings. CONCLUSION: The National Service Framework for Older People set a target for all hospitals treating stroke patients to have a stroke unit by April 2004. This study suggests that in many hospitals this is being achieved without adequate resource and expertise.

Stroke unit care and outcome: results from the 2001 National Sentinel Audit of Stroke (England, Wales, and Northern Ireland).

BACKGROUND AND PURPOSE: Stroke unit care is one of the most powerful interventions available to help stroke patients. There are limited data available to assess the impact of stroke units in routine clinical practice outside randomized clinical trials. This article uses data from the 2001 to 2002 National Stroke Audit to assess the effectiveness of stroke unit care in England, Wales, and Northern Ireland in delivering effective processes of care and in reducing case fatality and disability. METHODS: An observational study of the organization, structure, process of care, and outcomes for stroke in 2001. Case fatality after stroke in England was compared using data from the audit and routinely collected data from the Department of Health. 240 hospitals (196 Trusts) from England, Wales, and Northern Ireland took part in the 2001 to 2002 National Stroke Audit, a response rate of >95%. These sites assessed a total of 8200 patients using the Royal College of Physicians Intercollegiate Working Party Stroke Audit Tool. RESULTS: The availability of stroke unit care varies hugely across the country. Case fatality after stroke was higher in Trusts with least availability of stroke unit care. These differences persisted after control for case mix. The process of care was better for patients managed on stroke units compared with other settings. Overall, the risk of death for patients who received stroke unit care was estimated to be approximately 75% that of the risk for those having no stroke unit care (95% CI, 60 to 90). CONCLUSIONS: Stroke unit care as provided in routine clinical practice in England, Wales, and Northern Ireland reduces case fatality by approximately 25%, which is in line with the figures obtained from systematic analysis of stroke unit trial data.

Older stroke patients in Europe: stroke care and determinants of outcome.

BACKGROUND: in order to implement cost-effective stroke services for older patients, it is necessary to identify how stroke care is currently provided for these patients and how provision relates to outcome. OBJECTIVES: to estimate the structure and process of care, and identify independent factors associated with 3 month mortality and functional outcome in patients aged over 75 years compared with younger stroke patients across Europe. SETTING: 13 hospitals in 10 European countries. SUBJECTS AND METHODS: 1,847 subjects with first in a lifetime stroke admitted to hospital. Sociodemographic details, acute case severity, resource use and 3-month survival and dependency were collected. RESULTS: from a total of 1,847 patients, 1,112 patients (60%) were under 75 years. Older stroke patients were more likely to be incontinent, dysphasic, dysphagic and comatose (P < 0.001). Computed tomography scan rates were higher in younger (87%) than in older patients (79%) (P < 0.001). Access to organised stroke care was higher in older (58%) than in younger patients (51%) (P = 0.002). Median acute length of stay was longer in younger (14 days, range 7-21 days) than in older patients (11 days, range 8-22 days) (P = 0.04). Nursing time in hospital was higher in older patients (P = 0.01), whilst therapy time was higher in younger patients (P = 0.03). By 3 months, younger patients were more likely to receive outpatient care (P < 0.001), physiotherapy (P < 0.001) and occupational therapy (P < 0.001). For older stroke patients, not having a computed tomography scan (OR = 0.2, 95% confidence intervals (CI) = 0.01-0.6, P = 0.003) was significantly related to mortality at 3 months after adjusting for case mix. Access to organised stroke care was significantly associated with reduced 3-month mortality in younger patients only (OR = 0.29, 95% CI = 0.14-0.6, P < 0.001). CONCLUSION: stroke care varies considerably across European centres, with older people more likely to gain access to organised stroke care in many centres but less likely to receive diagnostic investigations, therapy input and outpatient review. Where there is evidence of age discrimination for access to stroke services, guidelines need to be adopted to ensure patients of all ages receive optimal evidence-based stroke care at all stages of their illness.

Self ratings of health predict functional outcome and recurrence free survival after stroke.

STUDY OBJECTIVE: To measure stroke victims' self rated health (SRH) status and SRH transition, and to compare how the two are prospectively associated with disability and recurrence free survival. DESIGN: Prospective case registry study with face to face follow up interviews at three months, one, two, and three years. Ascertained were SRH status and SRH transition using single question assessments, Barthel Index (BI), Frenchay Activities Index (FAI), and Mini Mental State Examination (MMSE). SETTING: A multiethnic inner city population of 234 533. PARTICIPANTS: Patients surviving the initial three months after a first in a lifetime stroke in 1995 to 1998. RESULTS: Of 690 stroke survivors 561 (81.3%) could complete the self report items. Answers to the item on SRH status did not vary significantly between the four follow up interviews. However, responses to the item on SRH transition changed significantly during follow up with three months ratings being more negative than all subsequent ratings. SRH transition, but not SRH status, showed a prospective association with long term outcome in multivariate analyses controlling for the BI, FAI, and MMSE. Compared with all other patients, patients reporting "Much worse health" at three months were more likely to be disabled ( = BI<20) at one year (OR 6.29, 95% CI 2.26 to 17.52) and their combined risk of stroke recurrence and death was increased over five years (HR 1.72, 95% CI 1.25 to 2.38). CONCLUSIONS: Items on SRH should be used with caution in populations with high rates of disability and language problems, as many participants are unable to complete them. SRH transition may be a better predictor of disability and recurrence free survival after major medical events than SRH status.
