Optimizing outcomes for women with gestational diabetes mellitus (GDM) and their fetuses requires not only careful metabolic management, but also appropriately applied fetal surveillance techniques and thoughtful selection of the most advantageous timing and route of delivery. Whenever possible, these clinical decisions should be based on the highest level of evidence available and should weigh the likelihood and seriousness of both maternal and fetal/neonatal morbidity. In areas where high-level evidence is lacking, resources should be channeled to designing and implementing clinical studies to get at good answers. In this review, we examine what new information exists in the area of obstetric care of women with GDM since the time of the Fourth International Workshop-Conference in 1997 and highlight areas where there remains a need for sound evidence on which to base practice guidelines. The summary statement from the 1997 Workshop-Conference remarked that "the lack of data from controlled clinical studies on which management recommendations can be based was a prominent theme of discussion regarding antepartum management of GDM" (1). In the end, consensus was reached in the following areas of obstetric management:
