Maternal and fetal characteristics and causes of stillbirth in a tertiary care hospital of Nepal: secondary analysis of registry-based surveillance data

Abstract

ObjectivesStillbirth is one of the vital indicators of quality care. This study aimed to determine maternal-fetal characteristics and causes of stillbirth in Nepal.DesignSecondary analysis of single-centred registry-based surveillance data.SettingThe study was conducted at the Department of Obstetrics and Gynecology, Chitwan Medical College Teaching Hospital, a tertiary care hospital located in Bharatpur, Nepal.ParticipantsAll deliveries of intrauterine fetal death, at or beyond 22 weeks’ period of gestation and/or birth weight of 500 g or more, conducted between 16 July 2017 and 15 July 2019 were included in the study.Main outcome measuresThe primary outcome measure of this study was stillbirth, and the secondary outcome measures were maternal and fetal characteristics and cause of stillbirth.ResultsOut of 5282 institutional deliveries conducted over 2 years, 79 (1.5%) were stillbirths, which gives the stillbirth rate of 15 per 1000 births. Of them, the majority (75; 94.9%) were vaginal delivery and only four (5.1%) were caesarean section (p<0.0001). The proportion of the macerated type of stillbirth was more than that of the fresh type (58.2% vs 41.8%; p=0.13). Only half of the mothers who experienced stillbirth had received antenatal care. While the cause of fetal death was unknown in one-third of cases (31.6%; 25/79), among likely causes, the most common was maternal hypertension (29.1%), followed by intrauterine infection (8.9%) and fetal malpresentation (7.6%). Four out of 79 stillbirths (5%) had a birth defect.ConclusionHigh rate of stillbirths in Nepal could be due to the lack of quality antenatal care. The country’s health systems should be strengthened so that pregnancy-related risks such as maternal hypertension and infections are identified early on. Upgrading mothers’ hygiene and health awareness is equally crucial in reducing fetal deaths in low-resource settings.
