Evidence-based practice (EBP) "requires the integration of the best research evidence with our clinical expertise and our patient’s unique values and circumstances" (Sharon, Glasziou, Richardson, & Haynes, 2018).
For more information, please read: Evidence based medicine: what it is and what it isn't.
The EBP process
Evidence-based practice is a 5-step process:
Please refer to the sections below for more information on each step.

The first step in evidence-based practice is to define your clinical question. There are many frameworks that you can use in formulating your question, such as PICO.
Find out more about clinical questions on the following pages:
Once you have a well-formulated clinical question, you can start searching the literature. Refer to the 'Journals and Databases' page for databases related to your topic.
You should also look at the following of databases with evidence based materials:
|Resources for evidence-based research including best practice information sheets, systematic reviews and electronic journals and conference papers. Consumer health-care information is also available. Some content is only accessible via login and password through the Members Area.|
|The Cochrane Library comprises several databases of reviews of the effects of health care. Included is the Cochrane Database of Systematic Reviews - evidence-based systematic reviews prepared by the Cochrane Collaboration to provide high quality information to people providing and receiving care and those responsible for research, teaching, funding and administration at all levels.|
Once you have located some relevant literature, you will need to critically appraise the evidence.
There are many different types of study designs, which would affect how you would appraise the individual studies, and thus the weight you give each study. This is commonly represented in what is know as the Level of Evidence hierarchy.

Some key resource for appraising literature are:

Once you have implemented your evidence-based practice, you need to audit and evaluate it to see if it is effective.
Please refer to Chapter 8 of Evidence-based medicine: How to practice and teach EBM by Straus, Glasziou, Richardson and Haynes for guidance on how to do this.
A 'structured literature review' is a narrative literature review with "a clearly articulated search strategy" (Kable, Pich & Maslin-Prothero, 2012, p. 878). It has many elements similar to a systematic review (see below), but is a different methodology. The emphasis is on developing and documenting a precise and transparent search strategy.
Please refer to the article by Kable, Pich and Maslin-Prothero (cited below) for a detailed explanation of the methodology.

Please see our Systematic Reviews guide, if you are looking for systematic reviews or undertaking a systematic review.
