Aim To determine the trends in preterm birth (PTB) rates in Samrakshan after initiating a third-trimester screening protocol.

Methods The Samrakshan program of IRIA focused on clinical stage-based management of fetal growth restriction (FGR) in the third trimester integrating fetal Doppler studies with routine trimester-specific antenatal scans. Mean uterine artery pulsatility index (PI), umbilical artery PI, middle cerebral artery PI, and cerebroplacental ratio were assessed for all third-trimester pregnant women in the program.

Results From 2019 to 2022, 249 (18.33%, 95% CI: 16.34, 20.54) women had PTB with 221 (16.67%, 95% CI: 14.73, 18.75) PTBs between 34 and 37 gestation weeks and 22 (1.66%, 95% CI: 1.10, 2.50) PTBs at gestation < 34 weeks. The overall preterm birth rates showed a significant (chi-square p < 0.001) declining trend each year from 23.18% (n = 121) in 2019–2020 to 16.81% (n = 99) in 2020–2021 and 10.75% (n = 23) in 2021–2022.

Conclusion The declining trend of PTB rates in the Samrakshan program shows that the reduction of PTB is an added benefit of the integration of fetal Doppler studies in the third trimester of pregnancy.
