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

in NMR
The Lancet Neonatal Survival Series (2005)
Editors: JE Lawn and S Cousens
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

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

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

“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
