Evidence-based medicine and practice guidelines: Application to genetics

Abstract

The Professional Practice and Guidelines Committee of the American College of Medical Genetics has the responsibility of overseeing the development of guidelines for the practice of clinical genetics. In the past, most, if not all, guidelines were primarily based on expert opinion. However, recently the goal has become to develop guidelines that are more evidence-based, or at least, to recognize the level of evidence available to the authors of these documents. This article reviews the challenges that are faced by geneticists who are charged with the development of practice guidelines. © 2009 Wiley-Liss, Inc.
