Maternal and Newborn Health Study
The PRISMA Maternal and Newborn Health study is a prospective, open cohort study with a planned recruitment of about 20,000 pregnant women over three years across six research sites in two South Asian and three sub-Saharan African countries. Participants are pregnant women identified through active house-to-house and facility-based surveillance at less than 20 weeks gestation, as determined by ultrasound. High-quality data will be collected over 12 study visits: five antenatal care (ANC) visits, labor and delivery, and six postnatal care (PNC) visits up to one year postpartum. A total of 34 standardized maternal and fetal/infant outcomes will be assessed. The primary analysis will estimate the burden of adverse outcomes and examine the risk factors to inform potential intervention strategies. Data from this effort will also be used to develop normative values for pregnant and postpartum women, as well as predictive models to evaluate pregnancy risk.
Continuous Non-invasive Hemoglobin Monitoring Device Validation Study
The Masimo Total Hemoglobin SpHb® is a continuous and non-invasive handheld device to measure hemoglobin levels. Previous research has found that SpHb is able to accurately detect hemoglobin levels in adult patients with a similar degree of bias and standard deviation to point-of-care invasive method measurements. Generally, limited clinical evidence, lack of validation of Masimo at higher than and lower than hemoglobin threshold values, and scientific consensus supporting the use of Masimo for accurate hemoglobin testing for the diagnosis of anemia during pregnancy calls for further research. We will measure hemoglobin using a venous blood sample via hematology auto-analyzer complete blood count (gold standard) and the non-invasive device to assess agreement.
Bridging Global Gender Gaps in Disease Burden Estimation Study
The Bridging Global Gender Gaps (G3) in Disease Burden Estimation Study uses a mixed-methods, multi-phased approach to design a tool to capture how the symptoms of pregnancy and postpartum impact women’s health, functioning, and wellbeing. Without this, we cannot adequately measure the impact that maternal morbidities have on pregnant and postpartum women’s health-related quality of life. Globally, there is limited data that quantifies the number of women affected, leaving us unable to estimate the true burden of disease.
