The acquisition and implementation of new findings for clinical care in obstetrics and gynecology is at a more rapid pace than ever before. More understanding of the pathophysiology of disease coupled with improved screening technology and genetic information requires physicians to constantly update their knowledge-base and familiarize themselves with guidelines and advances in techniques as well as question old euphemisms. Medical specialties, including obstetrics and gynecology have moved from board certification as a solitary achievement to maintaining current knowledge- a continuous lifelong learning process.
