Evidence-Based Practice: A way of providing health care that is guided by a thoughtful integration of the best available scientific knowledge with clinical expertise. This approach allows the practitioner to critically assess research data, clinical guidelines, and other information resources in order to correctly identify the clinical problem, apply the most high-quality intervention and re-evaluate the outcome for future improvement (NLM PubMed MeSH).
The Evidence Pyramid is often used to illustrate the levels of evidence in the literature. When beginning your search for evidence, begin at the highest possible tier.
