Frameworks

Use frameworks to avoid falling down the information rabbit hole.

Frameworks also help

  • Identify searchable parts of a question
  • Refine results
  • Focus review process to relevant results

PEO is another framework that is especially useful when investigating a prognosis or likelihood of developing a certain condition as a result of a pre-existing condition or exposure. 

 

Patient/Population:  how would you describe the patient or population of interest? 

Exposure:  what pre-existing conditions does the patient/population have or what has the patient/population been exposed to?

Outcome:  the outcome of interest; unlike in PICO, the outcome is almost always used in the search terms with the PEO framework
