A birth attendant, also known as skilled birth attendant, is a health professional who provides basic and emergency care to women and their newborns during pregnancy, childbirth and the postpartum period. A birth attendant, who may be a midwife, physician, obstetrician, or nurse, is trained to be present at ("attend") childbirth, whether the delivery takes place in a health care institution or at home, to recognize and respond appropriately to medical complications, and to implement interventions to help prevent them in the first place, including through prenatal care. Different birth attendants are able to provide different levels of care.
