Under-five mortality has declined globally, however, proportion of under-five deaths occurring within the first 28 days after birth has increased significantly. This study aims to determine the impact of an educational intervention on neonatal care and survival rates in Nigeria. Sequential exploratory mixed methods design involving 21 health workers in the preintervention phase, while 15 health workers and 30 mother-baby dyads participated in the post-intervention phase. Data were collected using semi-structured interviews and non-participatory observation. Qualitative data were analysed using thematic analysis, while quantitative data were analysed using descriptive and inferential statistics. Healthy newborns were routinely separated from their mothers in the pre-intervention period. During this time, non-evidence-based practices, such as routine nasal and oral suctioning were performed. Skin-to-skin contact, and early initiation of breastfeeding was frequently interrupted. After the intervention, 80.6% were placed in skin-to-skin contact with their mothers, and twenty of these babies maintained contact with the mother until breastfeeding was established. There was decline in neonatal deaths post intervention. Independent T test analysis of the day of neonatal death demonstrates a significant difference in mean (P=0.00, 95% CI -5.629; -7.447- -4.779). Newborn survival can be improved through regular training of maternity health worker in evidence-based newborn care.
