Etiologies of Neonatal Mortality in a Tertiary Care Hospital in a Resource-Limited Setting

Abstract

Background: Neonatal mortality remains a major public health problem in low income countries. The survival within the first 28 days of life remains a challenge in such countries. Many strategies have been implemented to reduce deaths in children under five especially in sub-Saharan Africa. Laquintinie Douala Hospital benefits from some of these measures including a perinatal network and an emergency voucher. We aimed to describe the main causes of neonatal deaths at Laquintinie Douala Hospital. Methods: We carried out a cross-sectional study including files of all deceased neonates in the neonatal unit during a 24 months period from January 1st, 2017 to December 31st, 2018. Data collection included socio-demographic characteristics of the mothers and the newborns, clinical and therapeutic data and the evolution of the newborn. We used SPSS 20 software for data analysis with a p-value less than 0.05. Results: We included 270 files with an overall mortality rate of 13.1% and a sex ratio of 1.2. The main causes of death included prematurity (37.8%), neonatal infection (34.1%) and neonatal asphyxia (24.4%). The main factors associated with deaths included informal sector (OR = 5.49; 95% CI 0.86 - 34.77; p = 0.07) and a primary level of education for mothers, malaria during pregnancy (OR 2.28; 95% CI, 1.44 - 3.12; p = 0.0001), very preterm babies (OR 6.45; 95% CI 4.68 - 8.89; p < 0.001) and resuscitation (OR 1.63; 95% CI 1.25 - 2.13; p = 0.0001). Conclusion: Neonatal mortality was lower than data in previous studies but remains high. This highlights the need for caregiver training and improvement of antenatal visits in our setting.
