This study aimed to assess the magnitude, trends and determinants of intrapartum stillbirths in the public health facilities in Addis Ababa. A case-control study design was used along with quantitative data collection methods. Obstetric care data on key variables were collected from medical records of 728 cases and 1551 controls in the public health facilities during July 1, 2010 and June 30, 2015. Data were analysed using SPSS version 24 to determine associations and risk factors against intrapartum stillbirth. HMIS data from different sources were further analysed for the same period to determine trends of stillbirth in the public health facilities of Addis Ababa. Findings from this study showed a staggering high prevalence of stillbirth at an average rate of 28 per 1000 births during the period 2010-2015. This figure was comparable with the population level prevalence of prenatal death in Addis Ababa which was 30 per 1000 birth (Central Statistical Agency 2011:115). No statistically significant associations were revealed against the effects of maternal medical conditions including diabetes, hypertension, cardiac and renal diseases and key socio-demographic variables including age, parity and marital status, and intrapartum stillbirth. On the contrary, HIV and syphilis infections, foetal presentations, multiple pregnancy and the frequency of ANC visits during the index pregnancy had statistically significant associations with intrapartum stillbirth. Furthermore, low FHR, non-vertex foetal presentations and ruptured cervical membrane on admission to labour were among risk factors for intrapartum stillbirth. Similarly, women in the stillbirth group received substandard care regarding the timely assessment of foetal decent, cervical dilatation, labour induction, and episiotomy care compared to women in the livebirth group. Obstetrical complications including obstructed labour, eclampsia and preeclampsia were more common among women in the intrapartum stillbirth group indicating that the above variables were key determinant of intrapartum stillbirth. These findings suggest that poor quality of obstetric care during labour and childbirth were the underlying risk factors for intrapartum stillbirth. In conclusion, strategies to overhaul the obstetric care practices in the public health facilities through skills building, accurate use of labour monitoring tools, close supervisions, accurate classification of stillbirth, proper documentation, and ongoing research efforts. / Health Studies / D.
