For example in national audit this could be the top score or the national average Carer Someone (commonly the patient’s spouse, a close relative or a friend) who provides ongoing, unpaid support and personal care at home Carotid Doppler A noninvasive test which uses high frequency sounds waves to determine extent of blood flow through the carotid arteries in the neck. Used in the evaluation of stoke and TIA symptoms Carotid Carotid endarterectomy is a surgical procedure in which a Endarterectomy stenosis (narrowing) or ulceration of an atherosclerotic plaque in the carotid artery is removed. CT scan A CT scan (computerised tomography) of the head. A CT scan X-rays the body from many angles. The X-ray beams are detected by the scanner and analyzed by a computer. The computer compiles the images into a picture of the body area being scanned. These images can be viewed on a monitor or reproduced as photographs. Domain The organisation of stroke care was divided into key areas for summary presentation of results Inter Quartile Range The IQR is the range between 25th and 75th centile which (IQR) is equivalent to the middle half of all values Transient Ischaemic A transient ischaemic attack is less severe than a stroke Attack (TIA) in that all the symptoms disappear within a day (and often last for less than half an hour) Magnetic Resonance A non-invasive procedure that produces a picture of the Imaging (MRI) inside of the head without exposure to ionising radiation (X rays) Median The median is the middle point of a data set; half of the values are below this point, and half are above this point National Clinical National evidence based guidelines for stroke care Guidelines For published by the Intercollegiate Working Party Stroke (2004) for Stroke second edition 2004 http://www.rcplondon.ac.uk/pubs National Sentinel National audit at a specific point in time to identify levels of Audit practice and service provision across the country ------------------------------------------------------------------------------------------------------------------- 5 National Service The NSF for older people was published in March Framework for 2001. It set national standards and service models Older People of care across health and social services for all older Department of people whether they live at home, in residential care Health (NSF) or are being cared for in hospital. http//:www.publications.doh.gov.uk/nsf/olderpeople/index.htm Neurovascular An outpatient clinic for patients with Transient Ischaemic Clinic Attacks or minor stroke for further investigation Organisational Audit of the service organisation, particularly relevant in stroke audit due to the evidence supporting organised stroke services. Organisational The data was analysed using a formula to combine Score similar questions into an overall score for domains or key areas in the organisation of care. A score of 100 is the optimal score Secondary Measures to prevent recurrence of the same illness prevention Stroke Research A nationally funded organisation to increase participation in Network stroke research http://www.uksrn.ac.uk/ Stroke Unit Stroke Unit Trialists' Collaboration Trialists’ Organised inpatient (stroke unit) care for stroke (Cochrane Collaboration Review). In: The Cochrane Library, Issue 3, 2004. (SUTC) Chichester, UK: John Wiley & Sons, Ltd. Thrombolysis The use of drugs to break up a blood clot Trusts In the context of the UK’s National Health Service (NHS), trusts are organisational units, eg hospital trusts, community trusts, primary care trusts or combinations thereof. In this report it usually refers to hospitals --------------------------------------------------------------------------------------------------- 6 Definitions of models of care The NSF for Older People (which applies to England only) set out that all hospitals caring for people with stroke should have ‘a specialised stroke service” by April 2004. The definition used for a stroke unit (and used in this audit) is: Stroke unit - a multidisciplinary team including specialist nursing staff based in a discrete ward which has been designated for stroke patients. This category includes the following sub-divisions: Acute stroke units that accept patients acutely but discharge early (usually within 7 days). This could include an “intensive” model of care with continuous monitoring and high nurse staffing levels. Rehabilitation stroke units which accept patients after a delay of usually 7 days or more and focus on rehabilitation Combined stroke units (ie no separation between acute and rehabilitation beds) that accept patients acutely but also provide rehabilitation for at least several weeks if necessary. Key characteristics of all stroke units Five key characteristics were chosen from the Stroke Unit Trialists' Collaboration (SUTC) http://www.update-software.com/abstracts/AB000197.htm and subsequent papers, as markers of stroke unit organisation. The audit has assessed how many of these are in place. The 5 characteristics are: • Consultant physician with responsibility for stroke • Formal links with patient and carer organisations • Multidisciplinary meetings at least weekly to plan patient care • Provision of information to patients about stroke • Continuing education programmes for staff The Department of Health National Performance Indicator on the
