PICO is useful for medical questions and for topics where one thing is being compared with another.
|
Patient :. |
This is the “Who”. For this you need to think of age, sex, ethnic origins or other defining characteristics of the patient and the population |
|
Intervention : |
This is also sometimes known as exposure, and makes up the “What”. This is what is happening to the patient or population, so it could be a drug or a therapy, a screening questionnaire or a health improvement programme. |
|
Comparison : |
With what is the intervention (or indeed population) being compared? This could be a control group. |
|
Outcome : |
What outcome do you expect to see? For example, you may be interested in knowing whether an intervention has a health benefit, or whether an exposure results in mortality. |
