The Cost of a Knowledge Silo: A Systematic Re-Review of Water, Sanitation and Hygiene Interventions

Published in Health Policy and Planning, this paper by Loevinsohn et al.(2014) summarises a re-review of a Cochrane-standard systematic review of WASH interventions’ impact on child diarrhoea morbidity that tested the hypothesis that divisions between communities, disciplinary and practice, impede understanding of how complex interventions in health and other sectors actually work and slow the development and spread of more effective ones. The re-review suggests that some conclusions of the systematic review and earlier reviews should be reconsidered.
