NICHD, in partnership with the National Institute of Biomedical Imaging and Bioengineering (NIBIB) and the NIH Office of the Director, aims to leverage the RADx Tech program’s innovation funnel design—which was used by NIBIB to speed the development, commercialization and implementation of COVID-19 testing technologies—to accelerate the development of diagnostic devices, wearables, or other remote sensing technologies that can reduce SMM/MM for individuals residing in maternity care deserts during the first year of the postpartum period (namely, from day of delivery or end of pregnancy). The innovation funnel approach uses stage-gated, milestone-based award payments to compress the customary technology development timeline. this is accomplished by employing, in parallel, expert teams to address scientific/technical, regulatory, clinical, and commercialization requirements to validate, de-risk, scale up, manufacture, and deploy novel tests through seamless pipeline. Successful outputs from this Challenge may include technologies such as wearable devices, smartphone-enabled diagnostic tools, integrated sensor technologies, and diagnostic devices or tests for use at-home or at the point-of-care (POC). Solutions generated by innovators shall allow continuity of monitoring when access to care providers is limited and extend diagnostic and monitoring capabilities to support timely return to maternity care when necessary. Priority conditions for prediction, detection, diagnosis, and monitoring during the postpartum period may include cardiovascular diseases (such as cardiomyopathies), hemorrhage, sepsis, and mental health conditions (such as postpartum depression), which are recognized as associated with high rates of severe morbidity and mortality during the first year after delivery or end of pregnancy.
