Five Steps of Evidence-Based Practice:

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.
