Evidence-based practice (EBP) is the objective, balanced, and responsible use of current research and the best available data to guide policy and practice decisions, such that outcomes for consumers are improved. Used originally in the health care and social science fields, evidence-based practice focuses on approaches demonstrated to be effective through empirical research rather than through anecdote or professional experience alone.
An evidence-based approach involves an ongoing, critical review of research literature to determine what information is credible, and what policies and practices would be most effective given the best available evidence. It also involves rigorous quality assurance and evaluation to ensure that evidence-based practices are replicated with fidelity, and that new practices are evaluated to determine their effectiveness.
In contrast [to the terms "best practices" and "what works," evidence-based practice implies that 1) there is a definable outcome(s); 2) it is measurable; and 3) it is defined according to practical realities (recidivism, victim satisfaction, etc.). Thus, while these three terms are often used interchangeably, EBP is more appropriate for outcome-focused human service disciplines.
