From the National Association of Social Workers:
Evidence-based practice is a process in which the practitioner combines well-researched interventions with clinical experience, ethics, client preferences, and culture to guide and inform the delivery of treatments and services.
Evidence-based research may be identified as evidence-based practice, treatment, or intervention, or Evidence-informed intervention. When searching literature databases, use hyphenated [ evidence-based ] or a phrase search (using quotation marks) [ "evidence based" ] for best results.
