Incidence and risk factors for early neonatal mortality in newborns with severe perinatal morbidity in Uganda

Abstract

Objective: To determine the incidence and risk factors for early neonatal death among newborns with severe perinatal morbidity.

Methods: A prospective cohort study was performed of 341 newborns with severe perinatal morbidity admitted to the neonatal intensive care unit of Mulago Hospital, Uganda. All newborns were followed up for 7 days or until time of death. Information surrounding the mother's obstetric history and pregnancy, the birth, and the neonatal history was collected using an interviewer-administered questionnaire and by review of relevant records. Multivariate logistic regression analysis was performed to assess factors independently associated with early neonatal death.

Results: A total of 37 (10.9%) neonates died within 7 days, giving an incidence of early neonatal death of 109 deaths per 1000 live births (3 per 100 person-days). In multivariate analysis, respiratory distress (adjusted risk ratio [aRR] 31.29; 95% CI, 4.17-234.20; P=0.001) and inadequate fetal heart monitoring during labor (aRR 6.0; 95% CI 1.40-25.67; P=0.016) were significantly associated with an increased risk of early neonatal death.

Conclusion: Approximately one in 10 neonates with severe perinatal morbidity died within 7 days of birth. Respiratory distress and poor monitoring of labor were risk factors for early neonatal death.
