Some authors appear to use evidence-based practice and evidence-informed practice interchangeably [e.g., 1] but other authors identify significant difference [2-5]. The main difference is in the approach to evidence. Webber & Carr  suggest that, in evidence-informed practice:
Evidence is conceptualised as a more inclusive and non-hierarchical notion than proponents of evidence-based practice understand it. It equally values practice wisdom, tacit knowledge and all forms of knowing. It is thereby viewed as integrative, viewing practice and research less in opposition but more in support of one another. In particular, evidence-informed practice respects the role of practice research. (p. 19)
Rather than the hierarchy of evidence, Epstein  proposes a Wheel of evidence (see Figure 1) in which “all forms of research and information-gathering and interpretations would be critically assessed but equally valued” (p. 225).There can also be greater emphasis on practitioner wisdom and lived experience. Nevo and Slonim-Nevo  suggest that:
Research findings should not override, or take precedence over, clinical experience and clients’ wishes, values and knowledge. Rather, empirical evidence is better regarded as one component in the mutual and constantly changing journey of client and practitioner. Under the [evidence-informed practice] model, there is no need for the five-steps procedure recommended by [evidence-based practice] or any other fixed protocol. Rather, a wide range of information sources, empirical findings, case studies, clinical narratives and experiences are to be used in a creative and discriminating way throughout the intervention process. (p. 1178)
