Volume I is the first paper in a three part series.  It reviews the effectiveness of community-based service delivery models in treating SAM, comparing the early years of largely NGO implemented programmes (2000-2006) with more recent services which are largely integrated in to routine health services by Ministries of Health (2007-2013). It found these community-based models are able to deliver cost-effective treatment with exceptional clinical outcomes. However, although the model is a significant improvement on previous in-patient models, only a third of affected cases are actually able to access treatment. Volume II will explore the barriers limiting access to treatment and Volume III will explore possible programmatic changes to increase accessibility, asking what we can learn from other public health interventions.
