Infection remains a leading cause of neonatal mortality among infants delivered at a tertiary hospital in Karachi, Pakistan

Abstract

Introduction: The current cohort study was conducted to determine the frequency and compare the mortality rate with associated characteristics among low birth weight and normal birth weight infants during the neonatal period at a tertiary healthcare facility, Karachi.

Methodology: Close-ended structured questionnaires were used to collect information from the parents of 500 registered neonates at the time of birth. Follow-ups by phone on the 28th day of life were done to determine the mortality among low birth weight and normal birth weight babies during the neonatal period.

Results: The neonatal mortality rate ranged from as low as 2.4% in the normal birth weight and 16.4% in the low birth weight categories to as high as 96% in the very low birth weight category. Respiratory distress syndrome (24.2%) and sepsis (18.2%) were reported as the leading causes of neonatal deaths. The babies' lengths of stay ranged from 2 to 24 hours, and around 90% of neonatal deaths were reported in the first seven days of life. More than 6% of neonates died at home, and 7.6% of the deceased babies did not visit any healthcare facility or doctor before their death. In the 12-15 hours before their deaths, 13.6% of the deceased babies had been unattended. Around 90% of the deceased babies were referred from a doctor or healthcare facility.

Conclusions: The present estimates of neonatal mortality are very high among low birth weight and very low birth weight categories. Infectious diseases, including respiratory distress syndrome (24.2%) and sepsis (18.2%), were leading causes of neonatal deaths.
