Evidence-Based Practice

Evidence-based practice

Evidence-based practice (EBP) is a way of providing health care that is guided by a thoughtful integration of the best available scientific knowledge with clinical expertise. This approach allows the practitioner to critically assess research data, clinical guidelines, and other information resources in order to correctly identify the clinical problem, apply the most high-quality intervention, and re-evalutate the outcome for future improvement (from Medline). 


Sample Search

When creating your search strategy, use your PICO elements as a starting point. In my example I refer to them as search terms. Keep in mind, it is possible that all PICO elements will not end up in the search or maybe two searches will have to be conducted. The idea of my examples is to teach you how to navigate the databases and begin to understand the search strategy. The search strategy is a diffiuclty topic to convey in this format. Each search has unique things about it and is better discussed when learning the process. Please contact your librarian for more information on search strategy. I am happy to help you. 

For our sample search in Medline with Full Text, we will search for evidence-based articles on speech or language related treatment of aphasia. The instructions provided will show you step-by-step how to find clinical trials, meta-analyses and sytematic reviews. Includes notes on searching in CINAHL Complete.

 

For our sample search in PsycNet, we will search for evidence-based articles on autism relating to speech or language. The instructions provided will show you step-by-step how to find clinical trials, meta-analyses and sytematic reviews.

 

Meta-analysis: works consisting of studies using a quantitative method of combining the results of independent  studies (usually drawn from the published literature) and synthesizing summaries and conclusions which may be used to evaluate therapeutic effectiveness, plan new studies, etc. It is often an overview of clinical trials. It is usually called a meta-analysis by the author or sponsoring body. 

Systematic review: summarises the results of available carefully designed healthcare studies (controlled trials) and provides a high level of evidence on the effectiveness of healthcare interventions.
