Protocol for the Implementation of a Targeted Maternal and Newborn Service Delivery Bundle in Sierra Leone

Sierra Leone faces persistently high neonatal and maternal mortality rates, driven largely by delayed recognition and treatment of newborn respiratory distress and postpartum hemorrhage. In this protocol, we describe the planned implementation of a bundle of maternal and newborn clinical practices over a 36-month period across nine public health facilities in the Greater Freetown area and Bo District to address these critical gaps. The service delivery improvements include the World Health Organization (WHO) Essential Newborn Care Course (ENCC) Parts 1 and 2; Vayu bubble continuous positive airway pressure (bCPAP) and oxygen blenders for respiratory support; the WHO Postpartum Hemorrhage package; and obstetric risk stratification using point-of-care ultrasound (POCUS) and complementary diagnostics for maternal care improvement. We anticipate that this bundle of evidence-based clinical tools and training, reinforced by mentorship, structured checklists, and low-dose high-frequency (LDHF) practice, will significantly reduce perinatal and maternal mortality and morbidity. The bundle will be evaluated using a Hybrid Type 1 effectiveness-implementation design, utilizing routine health information system data, supplemented by project registers, skills assessments, and observations. By aligning with the Ministry of Health’s Child Survival Action Plan, the aim of this project protocol is to provide a sustainable and scalable model for reducing preventable maternal and newborn deaths in resource-constrained settings.
