Stroke: Clinical Guidelines
Original Editor - Naomi O'Reilly
Introduction[edit | edit source]
The momentum for evidence-based healthcare has been gaining ground rapidly, motivated by clinicians, and management concerned about quality, consistency and costs of healthcare intervention. The use of Clinical Guidelines, based on standardised best practice, have been shown to be capable of supporting improvements in quality and consistency in healthcare and is considered one of the main ways that evidence-based medicine can be implemented. Clinical Practice Guidelines was defined by Field and Lohr (1990) as "systematically developed statements to assist practitioners and patient decisions about appropriate health care for specific circumstances". 
According to Woolf et al (2012) Clinical Guidelines have become one of the foundation of efforts to improve healthcare and health care management. Methods of guideline development have progressed both in terms of process and necessary procedures and the context for guideline development has changed with the emergence of Guideline Clearinghouses and large scale guideline production organisations e.g National Institute for Health and Clinical Excellence .
Purpose[edit | edit source]
Clinical guidelines provide recommendations on how healthcare professionals should care for people with specific conditions. They can cover any aspect of a condition and may include recommendations about providing information and advice, prevention, diagnosis, treatment and longer-term management and are designed to support the decision-making processes in patient care. The content of a guideline is based on a systematic review of research literature and clinical evidence - the main source for evidence-based care.
"The aim of clinical guidelines is to improve quality of care by translating new research findings into practice. There is evidence that the following characteristics contribute to their use: inclusion of specific recommendations, sufficient supporting evidence, a clear structure and an attractive lay out. In the process of formulating recommendations, implicit norms of the target users should be taken into account. Guidelines should be developed within a structured and coordinated programme by a credible central organisation. To promote their implementation, guidelines could be used as a template for local protocols, clinical pathways and interprofessional agreements". 
- To describe appropriate care based on the best available scientific evidence and broad consensus;
- To reduce inappropriate variation in practice;
- To provide a more rational basis for referral;
- To provide a focus for continuing professional education;
- To promote efficient use of resources;
- To act as focus for quality control, including audit;
- To highlight shortcomings of existing literature and suggest appropriate future research. 
Limitations & Controversy[edit | edit source]
But Clinical Guidelines can have their limitations and there is controversy surrounding some recommendations within some guidelines e.g. controversy around use of tPA in Acute Stroke. Not every patient or situation fits neatly into a guideline. Guidelines can not always cover every eventuality and each patient's circumstance needs to be taken into consideration when a treatment is decided upon. Recommendations should be viewed as statements that inform the clinician, the patient and any other user, and not as rigid rules.
"The problems of getting people to act on evidence based guidelines are widely recognised. An overview of 41 systematic reviews found that the most promising approach was to use a variety of interventions including audit and feedback, reminders, and educational outreach. The effective interventions often involved complicated procedures and were always an addition to the provision of guidelines. None of the studies used the simplest intervention ie that is, changing the wording of the guidelines. We examine the importance of precise behavioural recommendations and suggest how some current guidelines could be improved. ... "

Stroke Clinical Guidelines[edit | edit source]
While the evidence base for stroke management and rehabilitation is increasing, substantial gaps still remain with an ongoing need for more research to improve both service delivery and more importantly patient outcomes.
Acute[edit | edit source]
Acute Clinical Guidelines fo Stroke tend to focus on the Medical Management covering interventions for Stroke or TIA during the acute phase, when the diagnosis is made, medical stability is achieved and early complications prevented, which approximates to the first 72 hours of care but in some instances extends into the rehabilitation phase when an individual has ongoing needs around their medical management and stabilisation of Stroke. Principally it covers interventions at the level of individual patients and their family/carers with recommendations related to diagnosis and management of the underlying disease based on the WHO-ICF framework level of pathology, over the course of the first few days while clinical stability is being achieved, complications prevented and rehabilitation can begin in earnest. 
Secondary Prevention[edit | edit source]
Research shows a substantially increased risk for further Stroke or TIA: greatest risk for further event within the first three months post Stroke; 26% within the first 5 years of a first stroke; 39% at 10 years . Guidelines for Secondary Prevention therefore focus on identification and reduction of risk for further event that are specific to each individual with priority being early implementation of secondary prevention occurring as soon as possible post stroke.
Recommendations incorporate medical management, such as use of aspirin, post Ischemic Stroke It also incorporate changes in lifestyle factors such as nutrition, physical activity, smoking that also address longer term secondary prevention, that as physiotherapists we can play a large role in.
Rehabilitation[edit | edit source]
This phase of the Stroke Recovery process focuses on the common issues that people with stroke will encounter as they recover from their stroke and is focused on person-centred outcomes of activities and participation rather than interventions aimed at pathology or impairments.  
Guidelines highlight the importance of the stroke specialist multidisciplinary team. Both timeframe and pathway for this process is not restrictive and often overlaps with the long-term management phase. This phase can cover a range of settings including an acute stroke units, stroke rehabilitation units, early supported discharge services and other community rehabilitation services.
Guidelines for this phase tend to focus initially on restorative approaches then changing towards compensatory and adaptive approaches towards the end of this phase (as the patient moves into the long term management phase). Although a natural plateau should not preclude access to ongoing rehabilitation.
Recommendations during this phase include management of specific losses and limitations that arise following a stroke (include: cognition; communication; continence) and contain recommendations for specific impairments (e.g. spasticity), activity limitations (e.g. driving), restricted social participation and quality of life (e.g. sex).
Long Term[edit | edit source]
Studies that have followed up people with stroke at varying times post stroke indicate that many people continue to make functional gains following interventions, months and years post stroke, across a range of functional abilities . Guidelines for this phase focus on the long-term management of individuals with stroke in relation to stroke-specific issues, combining long-term medical management, principally around secondary vascular prevention and the treatment of less common causes of stroke, with aspects of social participation and is concerned with person-centred and family-centred care.
Long Term Management can be very complex in nature as a result of the wide variety of individual circumstance that each individual post stroke is faced with. This creates a challenge for research and as a consequence, the evidence to guide recommendations here are more difficult to interpret, and often more sparse but this should not reduce the importance of this phase and the need for further research in this area in order to develop expert guidance on best practice.
