The first stage of any evidence-based research is formulating an answerable question. A well-formulated question will facilitate the search for evidence and will assist you in determining whether the evidence is relevant to your question.
An answerable question has a format that follows the PICO concept. The acronym translates to:
|
|
Example: |
| P (Problem or Patient or Population) | hospital acquired infection |
| I (intervention/indicator) | hand washing |
| C (comparison) | no hand washing; other solution; masks |
| O (outcome of interest) | reduced infection |
