Neonatal sepsis-related mortalities are the outcome of a complex interaction of maternal-foetal colonisation, transplacental immunity and physical and cellular defence mechanisms of neonates.


The objective of this study was to evaluate the risk factors of mortality in outborn neonatal sepsis.

Materials and Methods:

A 1-year prospective observational study was undertaken at a tertiary care centre. All referred neonates with maternal and neonatal risk factors of sepsis were enrolled. Blood culture, sepsis screen and other relevant investigations were performed.


The mortality rate of neonatal sepsis among outborns was 38.24%. The common presentations of these neonates were respiratory distress, lethargy and hypothermia. On univariate analysis, significant risk factors for mortality included male sex (P = 0.05), weight on admission <1500 g (P < 0.001), hypothermia (P = 0.003), respiratory distress (P = 0.04), cyanosis (P = 0.001), convulsions (P = 0.02), prolonged capillary refill time (P < 0.001), thrombocytopenia (P < 0.001), abnormal radiological finding (P = 0.01), cerebrospinal fluid cellularity (P = 0.002) and positive C-reactive protein (P < 0.001). Maternal factors such as hypertension in pregnancy (P = 0.001) and antepartum haemorrhage (P = 0.03) were associated with statistically significant mortality. Gestational age (odds ratio [OR]: 0.49, confidence interval [CI]: 0.26-0.90, P = 0.02), weight on admission (OR: 1.57, CI: 1.08-2.27, P = 0.01), age at admission (OR: 0.89, CI: 0.78-0.99, P = 0.04), distance travelled with neonate (OR: 1.01, CI: 1.00-1.01, P = 0.003), duration of hospital stay (OR: 0.69, CI: 0.63-0.74, P < 0.001), hypothermia (OR: 1.87, CI: 1.01-3.42, P = 0.04), convulsion (OR: 2.88, CI: 1.33-6.20, P = 0.007), cyanosis (OR: 2.39, CI: 1.07-5.35, P = 0.03) and prolonged capillary refill time (OR: 3.34, CI: 1.78-6.24, P < 0.001) were the independent predictors of mortality in neonatal sepsis.


Gestational age; birth weight; long distance travelled with neonate and presentation with hypothermia, cyanosis, convulsions and prolonged capillary refill time were the independent risk factors for mortality in neonatal sepsis among outborns.
