The Momnibus Act seeks to comprehensively address and eliminate preventable maternal mortality, severe maternal morbidity, and maternal health disparities across the United States. It establishes a multi-agency task force to coordinate federal strategies and authorizes grants to community-based organizations to tackle the social determinants of maternal health , such as housing, nutrition, and environmental factors, particularly in high-need areas. The bill extends WIC eligibility for postpartum individuals and breastfeeding individuals to 24 months, aiming to improve maternal and infant health outcomes. It also provides sustained funding for community-based organizations to advance maternal health equity, prioritizing those led by and serving demographic groups with elevated rates of adverse outcomes. To combat bias and discrimination, the legislation mandates grants for respectful maternity care training for all employees in maternity care settings and requires a study on reducing such issues. It also establishes a compliance program for respectful maternity care in hospitals, including mechanisms for patients to report instances of racism or bias. The Act supports maternity health care and coordination programs for veterans, requiring annual reports on their maternal health outcomes. It also focuses on strengthening the perinatal workforce by issuing guidance to states on diverse care teams and authorizing grants to grow and diversify the workforce, including physician assistants, perinatal health workers, midwives, and perinatal nurses, with an emphasis on recruiting from diverse backgrounds and serving underserved areas. Improved data collection is a significant component, with funding for maternal mortality review committees to promote representative community engagement and expand their review to include severe maternal morbidity and mental health-related deaths. A comprehensive review of maternal health data collection processes and quality measures is mandated, alongside a specific study on maternal health among American Indian and Alaska Native individuals. The bill establishes a maternal mental health equity grant program to integrate mental and behavioral health services into maternity care, focusing on high-disparity groups, and provides grants to grow and diversify the maternal mental and behavioral health care workforce. For incarcerated individuals, it penalizes states that do not restrict the shackling of pregnant individuals and creates model programs and grants to optimize maternal health outcomes in federal, state, and local correctional facilities. Leveraging technology, the legislation supports telehealth tools for screening and monitoring pregnancy complications and authorizes grants to expand technology-enabled collaborative learning models and digital tools to promote equity in maternal health outcomes. It also requires a study on the use of technology and patient monitoring devices in maternity care, including potential biases. A Perinatal Care Alternative Payment Model Demonstration Project is established for states under Medicaid and CHIP to test payment models that improve maternal health outcomes and address disparities. Furthermore, the bill addresses maternal health during public health emergencies by authorizing funding for data collection, surveillance, and research, and establishing a task force to develop federal recommendations for respectful maternity care during such crises. Finally, the Act introduces measures to protect mothers and babies from climate change risks through grant programs for vulnerable individuals and health profession schools, and by establishing an NIH Consortium on Birth and Climate Change Research. It also continues the NIH's "IMPROVE Initiative" and enhances maternal vaccination awareness and equity campaigns, including pregnant and postpartum individuals.
