To search for evidence based information, you first need to develop a well formed clinical question. It is recommended that you use the PICO concept to help you do this. PICO stands for Patient/Population/Problem, Intervention, Comparison and Outcome/s.

This short, interactive tutorial below will help you understand and apply the PICO framework.

Finding filtered and unfiltered resources

What is meant by filtered and unfiltered resources?

Click on the links below to find comprehensive lists of evidence based resources:

Filtered or secondary sources are summaries and analyses of the evidence derived from and based on primary sources. They provide an appraisal of the quality of studies and often make recommendations for practice.

Primary or unfiltered sources provide evidence concerning a topic under investigation. Primary resources are generally articles that appear in peer-reviewed journals and are found primarily by searching databases.
