Book excerpt: Maternal-Fetal Medicine Evidence-Based Guidelines reviews the evidence for best practice in maternal-fetal medicine. It presents the reader with the right information, in the right format, by summarizing evidence in easy-to-use tables and algorithms. Each guideline is designed to "make it easy to do it right", with appropriate use of proven interventions and no use of harmful interventions. Plenty of evidence is available so that well-informed clinicians can reduce errors, so that the first aim is ultimately to improve the health of mother and fetus by providing quality care.
