Kira Johnson Act This bill establishes various grants for establishing or expanding programs to advance maternal health equity. Specifically, the Department of Health and Human Services (HHS) must award grants for community-based programs to improve maternal health outcomes for demographic groups with elevated rates of maternal mortality and morbidity, maternal health disparities, and other adverse outcomes; training for health care providers and others who work in maternity care settings on reducing and preventing racism, bias, and discrimination; and programs in hospitals, health systems, and other maternity care settings to establish processes to identify and address instances of racism or evidence of bias in maternity care (i.e., respectful maternity care compliance programs). HHS must contract with the National Academies of Sciences, Engineering, and Medicine to study issues related to the training programs, and the Government Accountability Office must study issues related to the respectful maternity care compliance programs.
