Setting
This pilot project was part of a Public-Private healthcare partnership between Delhi government (study hospital) and a corporate hospital (providing specialist fetal medicine sonographers). Data were prospectively collected between September 2017 and September 2019 at a 100-bed government secondary care hospital conducting approximately 6100 deliveries per year. This hospital caters to lower socio-economic population and has emergency obstetric services available at all times, a Blood Bank, and a Neonatal Intensive Care Unit (NICU).High risk pregnancies are referred early to tertiary hospitals for antenatal care or anticipated very small fetuses < 1000g are in-utero transferred to a tertiary hospital.
