Addressing the Challenge of Neonatal Mortality Simon Cousens
Millennium Development Goal 4 • Reduce by two-thirds, between 1990 and 2015, the under 5 mortality rate
Millennium Development Goal 4 • Source: Levels and trends in Child Mortality. Report 2011. Estimates developed by the Inter-agency Group for Mortality Estimation.

Community-based care: a seminal paper from India • Bang et al. Lancet 1999. 354: 1955-1961 • Implemented a home care package in a rural setting with high NMR • Trained village health workers to perform home visits, to promote breastfeeding and thermal management, in simple techniques to manage birth asphyxia, and to treat infections

The Lancet Neonatal Survival Series (2005) • Editors: JE Lawn and S Cousens
Source: Lancet 2005. 365:977-988 • Developed a model to estimate how many neonatal deaths could be prevented by increasing coverage of a package of relatively simple, cost-effective interventions • Estimated that 36-67% of neonatal deaths in 75 high mortality countries could be averted by high coverage (90%) with 16 interventions • Only about half of this reduction was through community-based care

Two recent studies:The Hala Trial, Pakistan • Lancet 2011. 377: 403-412
The Hala Trial, Pakistan • Intervention: • Lady Health Workers (LHWs) trained in preventive newborn care • Dais (TBAs) trained in basic newborn care • Communities encouraged to establish Community Health Committees • 16 clusters randomised: • Approximately 23,000 live births identified over a 30 month period • Primary outcome: all-cause neonatal mortality • Lancet 2011. 377: 403-412
The Hala Trial, Pakistan • Trial differed from other community-based trials in region in that intervention principally delivered through government health system rather than workers employed by research team. • lower intervention coverage than has been reported in other trials • smaller mortality impact • Despite limitations, encouraging that public sector programme promoting preventive care can produce health benefits
Cord care • WHO recommends dry cord care BUT in a Cochrane review from 2004 • all 21 trials were conducted in hospitals • all but one in high income settings • no systemic infections or deaths in any of the trials • Source: Zupan et al. Cohrane Database Syst Rev 2004. 3: CD001057
Cord care • A subsequent community-based trial of topical chlorhexidine in Nepal reported: • a 75% reduction in severe omphalitis • a 24% reduction in neonatal mortality compared with dry cord care • Source:Mullany et al. Lancet 2006. 367:910-918
Chlorhexidine trial, Pakistan • Lancet 2012. 379:1029-1036
Chlorhexidine trial, Pakistan • 187 clusters randomly allocated in 2x2 factorial design • 2 interventions • Chlorhexidine (daily for 2 weeks) vs dry cord care • Handwashing promotion vs no handwashing promotion • Interventions delivered through Dais • Facility births excluded • 9741 livebirths enrolled over 18 months
Chlorhexidine • “We could argue that more research is needed—questions certainly exist about the duration and timing of application and about external validity. Evidence from high-mortality populations in Africa would be useful. Nevertheless, to demand more evidence of effectiveness might be to repeat an old public health debate: if the need is clear, the possibilities attractive, and the risk low, how much evidence is necessary before we act on plausible findings?” • Osrin and Hill. Commentary. Lancet 2012. 379:984-986.
The challenge of neonatal mortality: what needs to be done? • Effective interventions are available: how do we make sure they reach mother’s and newborns? • Improve the quality and quantity of data available to: • assist rational policy making • Monitor progress
