Abstract
Evidence-based medicine is the use of current best evidence in making decisions about individual patients. It involves formulating a question, searching for information, appraisal of the literature, implementation and subsequent audit. Two case studies involving a non-linear hearing aid and cochlear implantation are used to illustrate the process. Critical appraisal of the evidence-based medicine in the general literature shows little sign that the approach is effective and indicates that further rigorous evaluation is a priority. It is suggested that systematic reviews and clinical practice guidelines should be a high priority for audiologists and that a working group of audiologists should form to promote their production.
