Evidence-Based Practice in Provision of Amplification
07 August 2020 (online)
Evidence-based practice (EBP) has been widely embraced in many health-care fields as a way of maintaining currency of knowledge and state-of-the-art treatment recommendations in an age of information abundance and rapid scientific progress. Although the principles of EBP are slowly entering the specialties of communication disorders, they are not well known or extensively employed as yet. In this article, the rationale for EBP is presented and differences between EBP and traditional practice are highlighted. The five-step process of EBP is described: defining the problem, searching for evidence, critically appraising the evidence, formulating a recommendation, and assessing the outcome. Critical appraisal calls for determination of the validity, clinical significance, and applicability of evidence. Each of these topics is explored with emphasis placed on the application of EBP to hearing rehabilitation. Finally some suggestions are offered for researchers and practitioners to facilitate a transition to EBP in amplification provision.
