Stroke is the leading cause of disability in Europe. There are around 1.2 million stroke survivors in the UK. More than half have been left with disabilities that affect their daily life.
The annual cost of stroke to the UK economy was £8.9 billion. Clinical response to stroke has often focused on resulting physical disabilities, but cognitive disability can be an equally substantial source of difficulty for patients and their carers. Sensitive and reliable assessment of cognitive disability following stroke is essential for identifying these needs in patients, and early assessment is a major benefit because problems soon after stroke are a strong prognostic indicator of future problems, and appropriate rehabilitation is most effective when started early.
Founded on longstanding expertise in neuropsychological studies, the University of Birmingham group has developed a comprehensive stroke-specific screening tool (the BCoS), which enables early and efficient detection of cognitive impairment after a stroke for a wider range of patients than is possible with existing methods. Through this development and its associated training programme, the BCoS is changing the way stroke survivors are assessed in the UK and internationally and it is influencing practice in other areas, such as traumatic brain injury.
Forster, House and Young have played a leading role in establishing the importance of long-term psychological and social distress after stroke, shifting the clinical emphasis (and evidence base) in stroke care from a limited focus on physical recovery to acceptance of the importance of psychological and social factors. Evidence we have generated has informed the stroke care pathway in national and international clinical guidelines that influence stroke service delivery, by providing guidance to clinical teams on psychological treatments after stroke and information provision. In tandem we have developed the methodology of stroke rehabilitation research, involving clinical staff in delivery of multi-site studies and thereby enhancing evidenced-based stroke care.
Worldwide, around 5 million stroke-related deaths occur annually, while another 5 million people are left with chronic disabilities following strokes. University of Glasgow research demonstrated that admission to a specialist stroke unit significantly improves patients' chances of survival and recovery. This discovery transformed the culture of stroke service delivery in the UK. These studies drove the development of new advice in national and international clinical practice guidelines and promoted the implementation of NHS healthcare targets and audit activities to standardise and evaluate the quality of stroke care. In the UK, the early death rate after stroke has fallen from over 45% to under 30% in the past 20 years; at least one-fifth of that decline is attributed to the introduction of stroke units.
Every year 15 million people worldwide experience a stroke. Of these, 5 million die and 5 million are permanently disabled. Life after stroke is never the same for many survivors. The research by Mead and Saunders from 2001 to 2012 has demonstrated that exercise training improves the physical fitness and physical function of stroke survivors and thus improves their quality of life.
The research has influenced health policy by underpinning the production of National Clinical Guidelines for stroke in the UK (NHS England & Scotland) and internationally (Australia, NZ, Canada). It has also been used to design and develop exercise after stroke services which have been implemented in the UK since 2007.
We have conducted studies to improve the recognition and treatment of post-stroke psychological problems. Our Motivational Interviewing (MI) study was the first, and one of only a few studies to show a positive impact of a talk-based psychological intervention following a stroke. This study has been recognized nationally and internationally and there is evidence that stroke-specific staff are accessing training in MI (e.g. UK Stroke Forum Education and Training, and the National Stroke Foundation in Australia). We are also collaborating in further research to evaluate the use of MI in the adjustment to other illnesses such as HIV, indicating that our work is beginning to have an impact in other areas of healthcare. We have developed national competences to underpin the development of training on the recognition, screening and management of psychological problems and enhancing communication skills. This research has contributed to the National Clinical Guideline for Stroke, National Competences, and improvements in the recognition of psychological distress and timely initiation of psychological support.
Stroke is a major health burden to patients, carers and the NHS, with UK costs estimated at £15.5bn annually. Clot-busting agents (thrombolytics) can substantially improve the consequences of ischaemic stroke, but only if administered rapidly. Newcastle research that recognised the importance of rapid referral to a stroke unit allowed reconfiguration of ambulance services for direct transport of victims to a specialised centre. Newcastle work also validated a test developed for paramedics to recognise the signs of stroke, which was developed as the nationwide Face-Arms-Speech-Time (Act FAST) campaign. Use of thrombolytics has increased eightfold between 2005 and 2012, and there has been a considerable increase in public awareness of FAST.
Stroke is the third most common cause of death and single most important cause of adult disability in the UK, affecting over 150,000 individuals per annum and costing the economy approximately £8 billion annually in health, social and indirect care costs.
High blood pressure (BP) is the most common modifiable risk factor to prevent stroke, but the use of BP-lowering therapy in the acute phase of stroke is controversial. Clinical trials co-ordinated at the University of Leicester have confirmed the safety of continuation of pre-existing BP-lowering therapy in acute stroke and the de novo treatment of high blood pressure in acute intracerebral haemorrhage. This has resulted in changes to the most recent US (2013) and UK (2012) guidelines, which will significantly impact on clinical management of this common clinical problem in acute stroke.
Research by the University of Nottingham's Division of Rehabilitation and Ageing has informed the effective implementation of evidence-based Early Supported Discharge (ESD) and community services for stroke survivors. The findings of an international consensus on the implementation of ESD have played a significant role in shaping local, regional, national and international service specifications. Qualitative and implementation studies have helped to shape better working practices between acute and community stroke services, including joint decision-making on who should be eligible for ESD and ensuring that services derive the full benefits of robust and relevant data capture.
Impact: Health and welfare; saving lives by determining that aspirin is an effective treatment for acute stroke and that heparin anticoagulation is ineffective.
Significance: In the UK, treating all acute stroke patients with aspirin and avoiding heparin means 1800 people avoid death or disability each year; aspirin is also highly cost-effective.
Beneficiaries: Stroke patients, the NHS, the economy.
Attribution: Sandercock, UoE, designed, led and reported the International Stroke Trial, and was on the steering committee of the Chinese Acute Stroke Trial.
Reach: Up to 15M stroke patients annually affected by guideline changes worldwide, encompassing Europe, North America and Australasia; educational events by the World Stroke Academy promote aspirin use.
The King's South London Stroke Register is the world's longest running, population-based stroke research register, assessing the incidence of stroke; the acute and long-term needs of stroke patients; and quality of stroke care. The South London Stroke Register provided data and analyses that informed the Parliamentary Public Accounts Committee report on stroke, the National Strategy for Stroke, and contributed to two National Audit Office reports on acute and longer-term stroke care. The latter contributed to a major service reconfiguration in London, which has led to lower mortality and more efficient use of health care resources for stroke. The King's South London Stroke Register provides a platform for designing and evaluating new models of stroke care, including the largest trial of Early Supported Discharge, a cost-effective intervention which is now provided in 66% of hospitals in England, as well as being rolled out internationally.
