Incidence and Causes of Stillbirth in Omdurman Maternity Hospital, Sudan: A Prospective Cross-Sectional Study

Background: Stillbirth is an important indicator of the quality of antenatal health services. This study aimed to identify the incidence and causes of stillbirths among Sudanese women. Method: This is a descriptive cross-sectional hospital-based study that was conducted at Omdurman Maternity Hospital during the period from December 1, 2019 to May 30, 2020. The study sample comprised 285 women who presented with stillbirths. Data were collected using a structured questionnaire administered to women after taking informed consent. Data were analyzed using descriptive statistics [Statistical Package for Social Sciences (SPSS) version 24 (IBM Corp., Armonk, NY)]. Results: The incidence of stillbirths was 16/1000. Idiopathic causes were the most frequent causes which accounted for 20% (n=57), followed by pre-eclampsia 18.6% (n=53), congenital abnormalities 15.1% (n=43), and abruption placentae 14.4% (n=41). In addition, the less common causes were eclampsia 4.6% (n=13), ruptured uterus 4.2% (n=12), twin-twin transfusion 4.2% (n=12), cord prolapse 3.5% (n=10), uncontrolled diabetes mellitus (DM) 3.5% (n=10), malpresentation 2.6% (n=8), gestational DM 2.5%(n=7), anemia 2.5%(n=7), sepsis 2.1 (n=6), placenta previa 1.4% (n=4), renal disease 0.4% (n=1), and toxoplasmosis 0.4% (n=1). Conclusion: The incidence of stillbirths was 16/1000. Unexplained causes of stillbirths were the most common causes which accounted for 20% of all deaths. In contrast, explainable causes were responsible for 80% of fetal deaths. Among explainable causes, pre-eclampsia and its consequences (abruption, eclampsia) remain the most common cause.
