The document discusses the need for an evidence-based approach in obstetrics and gynecology. It notes that while there is a lot of research evidence available, much of it is not applied in practice. It proposes creating an "Evidence Base Community" to better manage and disseminate research evidence to help close the gap between evidence and practice. This community would work on tasks like engaging stakeholders, developing guidelines, and implementing strategies to improve women's health outcomes based on the best available evidence.
