PICO and evidence based decision making sources
��Information Skills 3 (Year 2)��
This presentation outlines how to prepare a search for information and also looks at some sources for EBM
You then have the opportunity for some practice.
Why is it important to use databases when searching for information?
I use... all the time to find articles, especially for [SSiPs and] CATs!
Final year HYMS students answers…
I regularly use ... if I am writing or looking for research evidence to support my learning.
When searching for a paper to critically appraise...
(from a Library survey)
For every essay my first step is a multi-term advanced search on Embase
Each week there is an evidence based aspect to our PBL studies, using these ... enables me to find relevant documents .. I can incorporate into my learning ..
Prepare using PICO
To structure your thinking and your search
P is for…
Patient
Problem
Population or
I is for… Intervention (or treatment)
C is for… Comparison or control
Placebo?
Natural remedy?

Where next with PICO/PEO
Finding the evidence
Consider what you are looking for and where
A study found that you'd have to read
227 articles in the Lancet
or 118 articles in the New England Journal of Medicine
to get the relevant information that would be contained in
