Without a well-focused question, it could be difficult and time-consuming to identify appropriate resources and search for relevant evidence. Practitioners of Evidence-Based Practice (EBP) use a specialized model framework, called PICO, to form the question and facilitate the literature search1.
|P||Patient, Population, or Problem||How would I describe a group of patients similar to mine?|
|I||Intervention, Prognostic Factor, or Exposure||Which main intervention, prognostic factor, or exposure am I considering?|
|C||Comparison or Intervention (if appropriate)||What is the main alternative to compare with the intervention?|
|O||Outcome you would like to measure or achieve||What can I hope to accomplish, measure, improve, or affect?|
|What Type of question are you asking?||Diagnosis, Etiology/Harm, Therapy, Prognosis, Prevention|
|Type of Study you want to find||What would be the best study design/methodology?|
