This guide has been developed to serve as a “one stop source” for evidence searches for acquired brain injury interventions.
To develop a “one stop source” for evidence searches for acquired brain injury interventions. This listing directs individuals to existing data bases and systematic reviews. This list is compiled by Sheila MacDonald M.Cl.Sc. SLP (C)* with assistance of Nathan Zasler, MD
Although evidence based practice may be the intention of clinicians and researchers, the quest for appropriate systematic reviews within the field of ABI can be complex, time consuming and prohibitive for those who do not have library access. The availability of a “one stop source for evidence” can promote multidisciplinary dialogue internationally, consistency, and efficiency of knowledge translation. The first step in creating evidence based clinical practice is to point end users to the best available evidence.
This is a service of the International Brain Injury Association. It provides a brief listing of websites that present searchable data bases, ratings, summaries, abstracts, or full text of Systematic Reviews relevant to brain injury. The goal was to present websites that would be of assistance to all disciplines within the field of brain injury intervention.
Evidence Guide Selection Criteria
The primary intent of the One Stop Evidence Guide is to include those websites that meet the following selection criteria:
- Contain Systematic Reviews of studies relevant to ABI assessment and treatment
- Describe a systematic methodology for evaluation, classification and rating of papers
- Possess an expert review process with reviewers who are regulated healthcare professionals
- Are free (exceptions were made when an equivalent free website could not be identified)
Members requested that websites containing Guidelines relevant to ABI also be included. The National Guidelines Clearing House website can direct readers to all available published guidelines. Therefore only this website has been provided under the Guidelines heading. There are numerous guidelines which vary in scope and rigour and only some are based on the conclusions of systematic reviews. Websites leading to guidelines that are based on systematic reviews, and that meet the selection criteria, will be listed in the systematic review section of the evidence guide. Individual Articles are not listed. Rather, websites that direct one to data bases of multiple articles are included. Finally we included a few general websites relevant to evidence based practice for the benefit of readers.
Where to Search for Guidelines
National Guideline Clearing House TM (NGC) www.guideline.gov
The NGC is a resource for evidence-based clinical practice guidelines. It is an initiative of the Agency for Healthcare Research Quality (AHRQ), U.S. Department of Health and Human Services and was originally created in partnership with the American Medical Association and the American Association of Health Plans. It offers synthesesof selected guidelines that cover similar topic areas, and expert commentary on issues of interest and importance to the clinical guideline community. A search using the key words “brain injury” yielded 156 guidelines ranging on topics from acute care management of intracranial pressure to management of chronic pain.
Where to Search for Systematic Reviews
Open Access Sites to Search for Systematic Reviews Relevant to ABI
Academy of Neurological Communication Disorders (ANCDS)
Provides full text of all published systematic reviews prepared by the ANCDS Evidence Based Practice Committee for Traumatic Brain Injury , as well as systematic reviews pertaining to Apraxia, Aphasia, Dysarthria, and Dementia. Reviews were conducted by expert panels of clinicians and researchers with expertise in neurological communication disorders.
American Academy of Neurology (AAN) www.aan.com
AAN develops clinical practice guidelines to assist its members in clinical decision making related to the prevention, diagnosis, treatment, and prognosis of neurologic disorders. Each guideline makes specific practice recommendations based upon a rigorous and comprehensive evaluation of all available scientific data. A recent search under the key word “brain injury” yielded 6 guidelines specific to ABI, including topics such as brain death, coma, persistent vegetative state and management of concussion in sports. There are additional guidelines on related topics (i.e. headache).

Global Evidence Mapping Initiative GEM
GEM maps the available research in traumatic brain injury and spinal cord injury. The GEM worked with the neurotrauma community to identify questions of high importance in pre-hospital, acute care, rehabilitation, and long term care. Searches conducted within these key areas (e.g. Behaviour, Community Integration etc.) include the 2009 ERABI systematic reviews and search forward to 2010 to produce an evidence report for each topic. These maps will be regularly updated to reflect new published literature and there is a plan to expand the questions addressed over time. The GEM Initiative is funded by the Victorian Neurotrauma Initiative and based at the National Trauma Research Institute in Melbourne, Australia.
National Centre for Biotechnology Information; Pub Med, Medline, Clinical Queries in Medline
Through the National Centre for Biotechnology Information’s website, it is possible to conduct searches of systematic reviews in all journals indexed with PubMed, save these searches, access the abstracts, and sign up for email alerting of new publications that meet the search criteria. On the NCBI website users can access “My NCBI” in the upper right hand corner to register for these free services. PubMed comprises more than 19 million citations for biomedical literature from MEDLINE, life science journals, and online books. These searches usually do not include full text articles.

BMJ Clinical Evidence
This is a database produced by BMJ Publishing Group. It costs $285.00 US dollars per year (Discounts for members, nurses, students). It searches the world literature for the best available evidence from systematic reviews, RCT’s, and observational studies where appropriate and produces its own systematic reviews on the benefits and harms of clinical interventions. Each systematic review contains a page that lists key clinical questions and interventions and describes whether they have been effective or not. Interventions are rated according to the following categories: beneficial, likely to be beneficial, trade off between benefits and harms, unknown effectiveness, unlikely to be beneficial, and likely to be harmful or unbeneficial.
This is aclinical reference tool created by physicians for physicians and other health care professionals for use primarily at the 'point-of-care'. Individual and institutional subscriptions are available at an “affordable price” and the company can be contacted for quotes. It offers clinically organized summaries on more than 3000 topics. It is updated daily and monitors the content of over 500 medical journals and systematic evidence review databases directly and indirectly by using many journal review services. Each publication is reviewed cover-to-cover, and each article is evaluated for clinical relevance and scientific validity. The new evidence is then integrated with existing content, and overall conclusions are changed as appropriate representing a synthesis of the best available evidence.
General Resources for Health Information and Evidence Based Medicine
The following resources provide general health information and information relating to evidence based practice. They are not designed with the purpose of searching for systematic reviews relevant to brain injury
Agency for Health Care research
Under the Evidence-based Practice Centers (EPC) Program of the Agency for Healthcare Research and Quality (formerly the Agency for Health Care Policy and Research—AHCPR), 5-year contracts are awarded to institutions in the United States and Canada to serve as EPCs. The EPCs review all relevant scientific literature on clinical, behavioral, and organization and financing topics to produce evidence reports and technology assessments. These reports are used for informing and developing decisions, quality measures, educational materials, tools, guidelines, and research agendas. The EPCs also conduct research on methodology of systematic reviews.
Centre for Evidence Based Medicine

Includes theEBM Toolbox, an assortment of materials which are very useful for practitioners of EBM, and EBM Teaching Materials, including PowerPoint presentations.
Includes many resources for practicing and teaching EBM. The goal of this website is to help develop, disseminate, and evaluate resources that can be used to practice and teach EBM for undergraduate, postgraduate and continuing education for health care professionals from a variety of clinical disciplines.
