The Society for Maternal Fetal Medicine brings the first evidence based toolkit aimed to optimize the management of pregnancy using evidence based tools for reducing the rate of preterm birth. This app utilizes peer reviewed and Society endorsed algorithms for mitigation of risk factors in preconception and pregnancy care. The app is provided at no cost to users in an effort to reduce the rate of preterm birth and improve the health of mothers and their infants. The key drivers for prevention of preterm birth are identified and managed via evidence based interventions identified in the peer reviewed literature and Society guidelines included within the app.
