The Bridges to Moms program at Health Care Without Walls provides health and social services to homeless pregnant women and new mothers. ICH conducted a mixed-methods evaluation of the impact of Bridges to Moms during the program’s first two years. Using program and medical records data for mothers and infants, ICH determined the program’s influence on gestational age at birth, birth weight, and length of newborn stay in the NICU, as well as on postpartum engagement in primary care for mom and baby. Interviews with program participants helped determine the most meaningful components of Bridges to Moms, as well as participant satisfaction and areas for improvement. The results of the evaluation will be used to seek additional funding for the program and to contribute to the literature on serving at-risk urban populations.
