The PICO process is a method to help you frame a clinical research question at the beginning of your research. It is part of evidence-based practice.
Once you have formulated your PICO question, you can use elements of the question to search our databases for literature. For in-depth instruction on searching our databases, please see How to Search.
PICO or PICOT (with the addition of time frame) provides a systematic framework to help you identify the elements of a clinical question.
Population/Problem - Who or what are you trying to study?
Intervention- What action are you going to take?
Comparison - What action are you comparing your intervention to?
Outcome- What is the anticipated or hypothesized result?
Among hospitalized patients, what is the effect of a transitional care program compared to routine discharge planning on thirty-day readmission rates over a 6-month period?
| Applying PICO Framework | |
|---|---|
| Among (P) | hospitalized patients |
| what is the effect of (I) | a transitional care program |
| compared to (C) | routine discharge planning |
| on (O) | thirty-day readmission rates |
| over a (T) | 6-month period |
Now that we have a question, we can work on identifying keywords. Keep in mind, not all elements of the PICO will be used in your search. Starting with the P and I will help you keep your search broad in the beginning.
In hospital nurses, does antibacterial foam decrease bacteria count on hands as much as hand washing with soap and water?
| PICO Elements | Key Concepts | Possible Search Terms |
|---|---|---|
| P (Patient/Population/Problem) | hospital nurses | health personnel, nurses, nursing |
| I (Intervention) | using antibacterial foam | hand sanitizer, hand hygiene |
| C (Comparison) | hand washing with soap and water | handwashing |
| O (Outcome) | decreased bacteria count | infection prevention, bacterial colonization |
