Insights

Millions of newborns die annually. The Child Health and Mortality Prevention Surveillance (CHAMPS) network investigated causes of neonatal death, revealing complex causal chains involving infections, prematurity, and intrapartum events, highlighting critical prevention needs.

Area of Science:

  • Global Health
  • Pediatrics
  • Epidemiology

Background:

  • Neonatal mortality remains a significant global health challenge, with millions of deaths occurring within the first month of life annually.
  • Accurate data on the causes of neonatal death are crucial for developing effective prevention strategies.
  • The Child Health and Mortality Prevention Surveillance (CHAMPS) network was established to address this data gap in seven countries.

Purpose of the Study:

  • To investigate the underlying and contributing causes of neonatal deaths using a comprehensive methodology.
  • To analyze the full causal chain of events leading to neonatal mortality.
  • To identify key maternal factors associated with neonatal deaths.

Main Methods:

  • A multi-country surveillance study (CHAMPS) involving Medical and Social Autopsy (MITS) for neonatal deaths (December 2016-December 2021).
  • Comprehensive testing included cultures, multi-pathogen PCR, and histopathology.
  • Standardized verbal autopsy and clinical record review were used for data collection, with expert review for cause of death determination.

Main Results:

  • 1458 neonatal deaths were analyzed, stratified by timing: early (within 24 hours), late (1-6 days), and late (7-27 days).
  • Leading underlying causes included intrapartum events (31%), prematurity (28%), infections (17%), respiratory disorders (11%), and congenital malformations (8%).
  • Infections (40%), prematurity (32%), and respiratory distress syndrome (28%) were most common when considering the entire causal chain; 62% of deaths had additional conditions.

Conclusions:

  • Neonatal deaths often result from complex, multi-factorial causal chains, not single causes.
  • Maternal factors such as hypertension, delivery complications, and placental issues significantly contribute to neonatal mortality.
  • Improvements in prenatal care, obstetric management, and infection prevention are urgently needed in high-mortality settings to reduce preventable neonatal deaths.
