What’s your question?
What’s your need?– Background information– Current clinical information– Comprehensive literature review– Results from recent research
What’s your strategy for keeping current with the literature continuing to come out on your topic?
Good Background Information Sources include:

Three Databases of Primary Interestfor Clinical Investigation:

Cochrane Database of Systematic Reviews
Available from the Library’s Home page under “Core Resources – Evidence Based Medicine” and also through Ovid
Composed of 2 databases:– Cochrane Database of Systematic Reviews– Database of Reviews of Effects (DARE)
Benefits of Searching Cochrane & DARE Cochrane
– A Systematic Review identifies an intervention for a specific disease or other problem in health care, and determines whether or not this intervention works.
– Authors locate, appraise and synthesize evidence from as many relevant scientific studies as possible.
– They summarize conclusions about effectiveness.
– Systematic reviews differ from other types of reviews in that they adhere to a strict design in order to make them more comprehensive, thus minimizing the chance of bias, and ensuring their reliability.
DARE – Contains abstracts of systematic reviews and meta-analyses that have
been quality assessed. – Each abstract includes a summary of the review together with a
critical commentary about the overall quality.
