Determinants of neonatal mortality

To identify the common causes and contributory factors for high neonatal mortality in Pakistan and propose effective strategies to safeguard against it.

This retrospective study was carried out in Neonatal Unit (NNU) of Rawalpindi General Hospital (RGH) from January 1995 to December 1996. Relevant prenatal information obtained from referral forms, admission files or attendants was recorded on a proforma at the time of death of a newborn. This included obstetric and medical management of the mother, neonatal resuscitation and care, birth weight (wt) and gestational age. Cause of death was based on available clinical and laboratory data.

During the study period, there were 3005 admissions and 268 deaths, resulting in 9% neonatal mortality. Eighty-eight percent of this mortality was due to early neonatal deaths. More than 50% of deaths were unavoidable due to their critical condition at admission and occurred within first 24 hours of hospitalization. Neonatal infections and birth asphyxia were two major causes of neonatal mortality (37% and 31% respectively), followed by idiopathic respiratory distress syndromes (IRDS), Meconium aspiration syndrome (MAS) and congenital malformations. Sixty-eight percent of mortality was contributed by low birth weight (LBW), 74% of them being preterm suggesting high mortality among LBW-preterm infants. Other less common contributory factors were maternal medical disease, complicated deliveries and multiple gestation.

These causes and contributory factors of neonatal mortality reflect poor prenatal health services in this country. Hence there is a need for coordinated efforts to organise and regionalize MCH and prenatal health services with the help of a neonatal task force.
