Context: India has a high perinatal mortality rate. The Indian Radiological and Imaging Association (IRIA) is supplementing efforts to address perinatal mortality in India through the Samrakshan program. Aims: To describe various elements of the Samrakshan program that aims to reduce perinatal mortality in India. Methods: Samrakshan focuses on two priority areas, preeclampsia (PE) and fetal growth restriction (FGR). Samrakshan aims at technical skill upgradation, specifically focused on improved interpretative ability, prognostic and therapeutic efficacy using Doppler studies, a free online learning platform and offline continuous medical educations (CMEs), building an evidence base from the program to develop policy and guidelines, and improving synergy with the RAKSHA program of IRIA and other fetal care stakeholders. Results: Two courses on Doppler studies focused on first trimester and third trimester, supplemented by case discussions and journal articles, have started on the online platform with 230 registrants. The first statewide CME was held at Indore. Samrakshan screening identified 10 (17.24%, 95% CI: 8.59, 29.43) women at high risk for preterm PE and 29 (50.00%, 95% CI 36.58, 63.42) women at high risk for FGR in the first trimester. Ten fetuses (7.63%, 95% CI: 3.72, 13.59) including 9 with stage 1 FGR were identified in the third-trimester screening. Conclusions: Samrakshan is a flagship program of IRIA that aims to reduce perinatal mortality in India through a synergistic, holistic approach that complements and supplements existing efforts in India.

Context: High perinatal mortality in India may be caused by inaccurate dating of pregnancy resulting from suboptimal uptake of antenatal care and ultrasound services during pregnancy. Aim: To determine the discrepancy in the last menstrual period (LMP) assigned expected date of delivery (EDD) and ultrasound assigned EDD in pregnant women in a rural district of central India. Methods: Data from an ongoing cross-sectional screening program providing fetal radiology imaging in Guna district of Madhya Pradesh from 2012–2019 was analyzed for recall of LMP and discordance between LMP and ultrasound assigned EDD. The discrepancy was present when EDD assigned by ultrasound differed by 3 or more days at gestational ages less than 8+6 weeks, 5–7 days at gestational ages 8+6 weeks till 14 weeks, and 7–10 days at gestational ages 14–20 weeks. Results: The program screened 14,701 pregnant women of which 4,683 (31.8+6%, 95% CI: 31.11, 32.61) could not recall LMP. EDD assigned by LMP and ultrasound matched in 7,035 (70.22%, 95% CI: 69.32, 71.12) of the remaining 10,018 pregnant women. EDD was overestimated by LMP for 26.06% (95% CI: 25.21, 26.93) women; these foetuses were at risk of being misclassified as a term fetus. In 2018, the project had no maternal deaths, infant mortality rate of 24.7, low birth weight rate of 9.69%, and 100% antenatal coverage. Conclusion: Accurate dating of pregnancy and systematic follow-up integrating radiology imaging and obstetrics care for appropriate risk-based management of pregnant women can significantly improve perinatal statistics of India.

Aim The aim of the study is to determine improvements in perinatal mortality at the end of the first 2 years from the initiation of the Samrakshan program of the Indian Radiological and Imaging Association. Methods Samrakshan is a screening program of pregnant women that uses trimester-specific risk assessment protocols including maternal demographics, mean arterial pressure, and fetal Doppler studies to classify women as high risk or low risk for preterm preeclampsia (PE) and fetal growth restriction (FGR). Low dose aspirin 150 mg daily once at bedtime was started for pregnant women identified as high risk in the 11–136/7 weeks screening. The third-trimester screening focused on the staging of FGR and protocol-based management for childbirth and risk assessment for PE. Outcomes of childbirth including gestational age at delivery, development of PE, and perinatal mortality outcomes were collected. Results Radiologists from 38 districts of 16 states of India participated in the Samrakshan program that screened 2,816 first trimester, 3,267 second trimester, and 3,272 third trimester pregnant women, respectively. At 2 years, preterm PE was identified in 2.76%, preterm births in 19.28%, abnormal Doppler study in 25.76% of third trimester pregnancies, and 75.32% of stage 1 FGR delivered at term. The neonatal mortality rate was 9.86/1,000 live births, perinatal mortality rate was 18.97/1,000 childbirths, and maternal mortality was 58/100,000 live births compared with 29.5, 36, and 113, respectively in 2016. Conclusion Fetal Doppler integrated antenatal ultrasound studies in Samrakshan led to a significant reduction in preterm PE rates, preterm birth rates, and a significant improvement in mean birth weights. Perinatal, neonatal, and maternal mortality rates are significantly better than the targets for 2030 set by the Sustainable Development Goals-3.

Aim To determine the diagnostic effectiveness of third-trimester fetal Doppler studies in pregnancy for stillbirths and neonatal mortality in the Samrakshan program of the Indian Radiological and Imaging Association (IRIA). Methods The mean uterine artery (UtA) pulsatility index (PI) > 95th percentile, umbilical artery PI > 95th percentile, middle cerebral artery (MCA) PI < 5th percentile, and/or cerebroplacental ratio (CPR) < 5th percentile in the third trimester fetal Doppler study was considered as abnormal. The results of the fetal Doppler study closest to childbirth were considered for analysis. Late stillbirth (SB) was defined as a fetal loss between 28 and 36 gestation weeks and the term SB was defined as a fetal loss at ≥ 37 gestation weeks. Neonatal death was defined as the demise of a live-born baby within the first 28 days of life. Parameters of diagnostic effectiveness such as sensitivity, specificity, positive and negative predictive values and likelihood ratios, diagnostic odds ratio, and the area under receiver operator characteristic (AUROC) curve were assessed. Results Screening of 1,326 pregnant women in the third trimester of pregnancy between September 2019 and February 2022, identified 308 (23.23%) abnormal Doppler studies, 11 (0.83%) SB, and 11 (0.84%) neonatal deaths. An abnormal Doppler study was significantly associated with late stillbirths (OR 37.2, 95% CI: 2.05, 674) but not with term SB (OR: 3.38, 95% CI: 0.76, 15) or neonatal deaths (OR 1.39, 95% CI: 0.40, 4.87). Mean UtA PI, umbilical artery PI, MCA PI, and CPR were significantly associated with late SB and not term SB. The AUROC of Doppler measures was excellent for late SB but did not show discriminatory ability for term SB or neonatal deaths. Conclusion Integration of fetal Doppler with routine third-trimester antenatal scans can help identify pregnant women at high risk for late SB. The effectiveness of fetal Doppler to identify pregnant women at high risk for term SB and neonatal deaths needs further study on a larger sample size.
