An Integrating Model for Rapid Reduction of Maternal Mortality Due to Primary Postpartum Haemorrhage - Novel Use of the Catalyst Approach to Public Health.

On average 16%-53% of maternal deaths are from postpartum haemorrhage (PPH), with confidence intervals for Eastern Asia reaching beyond 60%. Success in preventing PPH mortality across many large low-resource populations has been fairly limited. Niger's government and an international non-governmental organization (NGO) have developed a model aiming to rapidly reduce primary postpartum haemorrhage mortality, combining relatively new technologies, misoprostol, condom tamponade, and non- inflatable anti-shock garment, with systematic measurement of blood loss and a set of traditional public health tools that constitute the Catalyst Approach to Public Health, with action steps for each phase if haemorrhage occurs. This paper describes each component and testing of the hypothesis that the model can effectively reduce PPH mortality on a national scale. The Niger model is a 'complex intervention' aiming to maximise impact from existing health system resources even in remote areas. The broad applicability of Niger's approach to address a serious global public health problem, and its innovative nature warrant describing the model itself, with results to be published separately. Combining this set of individually proven technologies and a set of organisational tools from disease eradication settings as a single 'complex intervention', has to our knowledge not been described before.
