Western Alliance Seminar Series Seminar 2 – Searching for evidence?
Why use PICO?1
If you do a search on a topic and find that you have lots of non-‐relevant results, you can
either visually scan them all OR find a way to develop a more targeted research question.
One way to do this is to use the ‘PICO’ method.
What is PICO?
PICO stands for Patient/Intervention/Comparison/Outcomes. The PICO method helps you to
develop an answerable question. PICO defines the clinical question in terms of the specific
patient problem, which aids the researcher in finding clinically relevant evidence in the
literature.
P Patient/population/problem Describe the population or target group
I Intervention What is the main intervention or program
C Comparison What is the alternative or comparison intervention
O Outcome What is the effect or what do you want to achieve
Example of PICO It can be easier to think about PICO with some real examples. Let’s use the research question
from our first seminar and see how it would look in a PICO format.
Original question -‐ Why are parents reluctant to bring their children for MMR
vaccination when advised by their GP that it’s for the best?

Population: Parents of children without MMR vaccination.
Intervention: MMR vaccination education.
Comparison: Parents with no MMR vaccination education.
Outcome: MMR vaccination uptake. Change in attitude and beliefs.
Figure 1. Example of PICO with our research question
Now we can rewrite our research question using PICO:
Do parents who receive MMR vaccination education change their attitude and beliefs and/or level of MMR vaccination uptake with GPs, as compared to parents who do not receive the education intervention?
Figure 2. Revised question with PICO
Now, if you use PICO to develop your questions and terms the search will be more complex
than those we have done already, so the next step would be to write a literature review
protocol and decide which terms and which databases you might want to use e.g. PubMed,
PsycINFO.
See below for an example of possible terms you might use for your database searches.
MMR or vaccination AND attitude or beliefs
Parents OR mother OR carer OR patient

Another example of PICO2
Here is another example of a question that is reframed using PICO from Fink (2008), pp.48-‐
49.
Basic
question
How can we improve care for diabetic patients?
More
specific
question
How well does interactive computer technology compare to educational
material in improving quality of life when used as part of a comprehensive
treatment plan for primary care patients with Type 2 diabetes?
The more specific question details the population (patients with Type 2 diabetes), type of
program being sought (interactive computer technology), a comparison program (written
education materials), and the desired outcome (improved quality of life).
How would this look in PICO?
P Patient/population/problem Primary care patient with Type 2 diabetes
I Intervention Interactive computer technology
C Comparison Written education materials
O Outcome Improved quality of life
