Brief Summary
Access to quality antenatal care (ANC) and postnatal care (PNC), including maternal, newborn, and infant services, is integral to reducing adverse pregnancy-related health outcomes and promoting positive birth experiences. The World Health Organization (WHO) recommends a total of eight ANC visits for pregnant women. However, the ANC coverage rate remains considerably lower among more vulnerable populations, and the quality of care that women receive is inconsistent, often poor, and frequently fails to detect risks in a timely fashion or adequately prepare women for the birth process. While rates of facility-based delivery are on the rise worldwide, disparities persist and the quality of care across facilities remains uneven. Even less information is available on PNC, where services beyond routine immunizations may not be widely available, especially in resource-poor regions. Additionally, limited evidence exists on innovative service delivery approaches and how to effectively scale tested maternal and newborn health (MNH) interventions. This coupled with the fragmented datasets from smaller studies limit our ability to advocate for policy change. The Pregnancy Risk Stratification Innovation and Measurement Alliance (PRiSMA) is implementing a harmonized open cohort study that seeks to evaluate pregnancy risk factors and their associations with adverse pregnancy outcomes, including stillbirth, neonatal mortality and morbidity, and maternal mortality and severe morbidity. The goals are to develop a harmonized data set to improve understanding of pregnancy risk factors, vulnerabilities, and morbidity and mortality and to estimate the burden of these risk factors and outcomes in LMICs. Ultimately, these data will inform development of innovative strategies to optimize pregnancy outcomes for mothers and their newborns.

Outcome Measures
Primary Outcomes (8)
Maternal Mortality
Death from any cause related to or aggravated by pregnancy or its management (excluding accidental or incidental causes) during pregnancy and childbirth or within 42 days of termination of pregnancy, irrespective of the duration and site of the pregnancy.
Assessed from time of pregnancy identification (on average, 10-20 weeks gestational age), through delivery or termination of pregnancy, and then 42 days postpartum
Composite Severe Maternal Outcomes
Composite outcome of maternal deaths + near-miss cases + potentially life-threatening complications + critical intervention.
Assessed through 12 months postpartum
Maternal Anemia
Low hemoglobin levels throughout pregnancy and labor and delivery, classified as mild (10-10.9 g/dL), moderate (7-9.9 g/dL), or severe (\<7 g/dL). Low hemoglobin levels in the postpartum period, classified as mild (11-11.9 g/dL), moderate (8-10.9 g/dL), or severe (\<8 g/dL).
Assessed from time of pregnancy identification (on average, 10-20 weeks gestational age) through 6 months postpartum
Stillbirth
Delivery of a fetus showing no signs of life, as indicated by absence of breathing, heartbeat, pulsation of the umbilical cord, or definite movements of voluntary muscles. The primary definition for the study is death prior to delivery of a fetus at \>=20 weeks of gestation (or \>350 g weight, if gestational age is unavailable). Additionally, we will analyze time-specific definitions: Early stillbirth (20-27 weeks), Late stillbirth (28-36 weeks), Term stillbirth (\>=37 weeks), and WHO stillbirth (\>=28 weeks).
Assessed at delivery
Neonatal Mortality
Death of a live-born baby during the first 28 days of life from any cause.
Assessed delivery to 28 days of life
Preterm Birth
Delivery prior to 37 completed weeks of gestation of a birth (live or stillbirth). Further classified as extremely preterm (\<28 weeks), very preterm (28-32 weeks), and moderate to late preterm (32-37 weeks). For these, gestational age at birth will be determined by the best obstetric estimate: last menstrual period, Ultrasound (method to be determined), and ACOG algorithm.
Assessed at delivery
Low Birth Weight
Defined as birth weight \<2500 g and very low birth weight \<1500 g.
Assessed at delivery or within 72 hours for home births
Small-for-Gestational-Age (SGA)
Combined gestational age information and birthweight will be used to further categorize into: preterm-SGA, preterm-AGA, term-SGA, term-AGA.
Assessed at delivery
Secondary Outcomes (20)
Late Maternal Mortality
Assessed from 42 days postpartum up to one year
Preeclampsia
Assessed from time of pregnancy identification (on average, 10-20 weeks gestational age) through 42 days postpartum
Preterm Birth Indication
Assessed at delivery
Preterm Premature Rupture of Membranes (PPROM)
Assessed at <37 weeks of gestation
Gestational Hypertension
: Assessed from 20 weeks gestational age through delivery
- +15 more secondary outcomes
Eligibility Criteria
The investigators will identify, screen, and enroll pregnant participants through pregnancy surveillance systems, with a goal of identifying pregnancies prior to 20 weeks of pregnancy. Pregnant women will be assessed at \<20, 20, 28, 32, and 36 weeks gestation, at labor and delivery, and at 3 days and 1, 4, 6, 26, and 52 weeks postpartum. Infants will similarly be assessed at 3 days and 1, 4, 6, 26, and 52 weeks of age.
