This model helps us create searchable clinical questions before we start looking at the literature. 

The hardest part of EBP is often formulating a question -- you have to gather the pieces of puzzle before you can start putting it together. 

P - Population 

I - Intervention

C - Comparison or Control

O - Outcome (desired or of interest)

T - Time

Question: In POPULATION, does INTERVENTION as compared to COMPARISON/CONTROL GROUP result in OUTCOME?

This mnemonic device helps us frame out question before we start searching for evidence. 

Keep in mind, you may not have all the pieces depending on your type of question, but it's a great jumping off point.
