This 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.

Severe maternal morbidities (SMM) are outcomes of labor and delivery that result in serious effects on short- or long-term health. Many SMM represent "near miss" events for maternal deaths. In Georgia, Black women experience SMM at a rate far higher than women of other races and ethnicities. Equity-centered models of care - such as embedding patient navigators into the maternity care continuum - offer promise for improving maternal health through meeting the social needs, lowering stress, and promoting access to and utilization of care for those giving birth. To date, however, research about maternity care navigation's effectiveness and needed inputs for its adoption into clinical care are lacking. To fill this research gap, the investigators propose to complete a pragmatic randomized controlled trial (RCT) of integrating community-based patient navigators into maternal care of Black women being cared for through Grady Health System (a safety net health system in Atlanta). 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. The first arm (the comparison group) will receive the standard of care. The second arm (the intervention group) will receive a community-based patient navigator with 3 prenatal contacts and 5 postpartum contacts; during each contact, the community-based patient navigator will offer health assessment and education, along with group education and social support. For participants in both arms, the researchers will collect data on patient-level measures upon enrollment (<20 weeks' of pregnancy), at 6-8 weeks postpartum, and at 12 months postpartum; data collection will involve questionnaires, review of case logs and review of medical records. Measures of effectiveness will include the number of SMM and maternal death events per woman (primary outcome). To evaluate how the intervention might reduce primary outcomes, questionnaires will also assess measures of unmet need, stress and depressive symptoms, attendance of prenatal and postpartum care. Embedded process evaluation will assess the number and content of navigation encounters in which the woman participates and the acceptability of the intervention from patient and provider perspectives.

Written informed consent will be obtained as a criterion for participation. All participants will be compensated for their time. Confidentiality will be maintained on several levels including training of investigators and staff, restrictions on data access, and use of HIPPA-compliant data storage procedures. Data will be stripped of identifiers before analysis and destroyed when no longer needed.

This study will be among the first to 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. 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.

Inclusion Criteria:

• A pregnant woman or individual (inclusive of all gender identities) who is Black and English-speaking (by self-report),
• ≥18 years of age who is capable of consenting for oneself and who presents for prenatal care with a singleton pregnancy ≤ 20 weeks gestation (confirmed by medical record),
• covered by Medicaid
• for whom the AHC-Health Related Social Needs Tool (administered as part of standard clinical care for prenatal patients) identifies ≥1 unmet social needs
• expectation to receive prenatal care and deliver at Grady and be available through 12-months postpartum to assure opportunity for exposure to the intervention, process, and outcome measure ascertainment.

Exclusion Criteria:

• The intent to transfer care to a health system outside of metro Atlanta
• incarceration, which would interfere with intervention provision and outcome ascertainment
• adults unable to give consent
• individuals who are not yet adults
• prisoners
• cognitively impaired individuals with impaired decision-making capacity
• individuals who are not able to clearly understand and speak English (as the PPP-PN intervention is only available in English at this time)

De-identified data related to the primary and secondary endpoints will be shared, including severe maternal morbidity (SMM) and death events, health care utilization data, health care quality data (receipt of guideline concordant care), and patient-reported outcomes (unmet social needs, emotional support, quality of life, perceived stress and depression, substance use, perceptions of care, satisfaction with care)

Data will become available in the final year of the study (Year 5, anticipated starting September 2026) when all data collection is complete and will be available thereafter.

Consistent with the NIH Data Sharing Policy, the investigators will make the de-identified data and associated documentation available to users under a data-sharing agreement. To gain access to study data, anyone not part of the original research protocol will submit a Data Analysis Request Form, which requires elucidation of the specific data requested along with a statement that the investigator must provide: 1) a commitment to using the data only for research purposes and not to identify any individual participant; 2) a commitment to securing the data using appropriate computer technology; and 3) a commitment to destroying or returning the data after analyses are completed.
