PICO

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:

  • P – Populations/People/Patient/Problem
  • I – Intervention(s)
  • C – Comparison
  • O – Outcome

 

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

The five steps of EBP

Evidence-based practice consists of five steps:

  1. Ask a searchable clinical question;
  2. Find the best evidence to answer the question;
  3. Appraise the evidence;
  4. Apply the evidence with clinical expertise, taking the patient's wants/needs into consideration;
  5. Evaluate the effectiveness and efficiency of the process.
