The Department of Health and Human Services, through the National Institutes of Health (NIH), has issued a Notice of Funding Opportunity (NOFO), titled "Understanding the Impact of Healthcare System and Clinician Factors on Disparities in Maternal Morbidity and Mortality." This initiative aims to support innovative research focused on addressing maternal health disparities, particularly among racial and ethnic minorities, socioeconomically disadvantaged groups, and underserved populations in the U.S. Researchers are invited to apply for R01 grants to investigate multiple facets of maternal morbidity and mortality, including the influence of healthcare access, quality, and social determinants of health. The NOFO aligns with the NIH's IMPROVE Initiative, emphasizing the need for studies that address preventable causes of maternal deaths and significantly enhance care pre-, during, and post-delivery. Key objectives include exploring the impact of factors such as insurance coverage, clinician-patient communication, and healthcare system policies on maternal outcomes. Applications are due by February 5, 2024, with the possibility of funding for projects spanning up to five years. This initiative highlights the federal commitment to reducing maternal health disparities and improving outcomes across various demographics.
