Abstract Background Globally, 2.6 million stillbirths occur every year. Of these, 98% occur in developing countries. According to the United Nations Children’s Fund, the neonatal mortality rate in Zambia in 2014 was 2.4%. In 2016, the World Health Organization released the International Classification of Diseases - Perinatal Mortality (ICD-PM) as a globally applicable and comparable system for the classification of the causes of perinatal deaths. However, data for developing countries are scarce. The aim of this study was to evaluate the rates and causes of stillbirths and neonatal deaths at a local hospital in Zimba, Zambia to identify opportunities for preventive interventions. Methods All cases of stillbirths and neonatal deaths at Zimba Mission Hospital in Zambia in 2017 were included in this study. Outborn neonates who were transferred to the hospital and later died were also included in the study. Causes of stillbirths and neonatal deaths were analyzed and classified according to ICD-PM. Results In total, 1754 babies were born via 1704 deliveries at the hospital, and 28 neonates were transferred to the hospital after birth. The total number of perinatal deaths was 75 (4.2%), with 7 deaths in the antepartum, 25 deaths in the intrapartum, and 43 deaths in the neonatal period. Most antepartum deaths (n = 5; 71.4%) were classified as fetal deaths of unspecified causes. Intrapartum deaths were due to acute intrapartum events (n = 21; 84.0%) or malformations, deformations, or chromosomal abnormalities (n = 4; 16.0%). Neonatal deaths were related primarily to complications from intrapartum events (n = 19; 44.2%); low birth weight or prematurity (n = 16; 37.2%); or infection (n = 3; 7.0%). Conclusions Perinatal deaths were associated with acute intrapartum events and considered preventable in 40 cases (53.3%). Effective interventions to prevent perinatal deaths are needed.
