RecruitingBehavioural interventionTrial of Community-based Patient NavigationThis study will test the effectiveness of a community-based patient navigator intervention from mid-pregnancy through 12 month postpartum for a high-risk population of medically underserved women. The RCT will enroll 540 pregnant women before 20 weeks of pregnancy and randomly allocate them into two different study arms from the time of prenatal enrollment through 12 months postpartum. If found to be effective, the community-based patient navigator intervention can be implemented as a standard of care at Grady and other provider practices serving high-risk women to improve maternal health outcomes and reduce racial disparities.
