To advance the call to action proposed in the Lancet Series on Ending preventable stillbirths in 2016, the Stillbirth Advocacy Working Group (SAWG) was established in 2017 by PMNCH. The SAWG is a group of parents, clinicians, researchers, policymakers, students and others who are interested in using advocacy as a tool to help end preventable stillbirths and support families and caregivers after a death. The group serves as a hub for global advocacy action and accountability for stillbirth prevention and post-stillbirth bereavement support. It also works to ensure that stillbirths are fully integrated into the reproductive, maternal and child health (RMCH) continuum of care, and reviews global and regional reproductive maternal child health reports and publications regularly to check how well stillbirth prevention and post-stillbirth support are integrated. In 2018, the SAWG had members from more than 50 organizations and was co-chaired by the International Stillbirth Alliance and the London School of Hygiene and Tropical Medicine.
