A Piot model to analyse case management in malaria control programmes

At the beginning of the 21st century, malaria remains one of the most important public health problems in the world. An important control strategy to address this burden is adequate case management of malaria patients. The success of this strategy, however, does not solely depend on diagnosis and treatment, but also on a sequence of steps that patients have to take when they are ill. Only when patients go through all these steps successfully will they be cured. In this paper, a model is presented in which these steps are described. The model provides a framework for analysing this type of malaria control strategy and for identifying the most critical challenges faced. Furthermore, the model is used to analyse recent literature on case management as part of malaria control programmes in order to highlight current knowledge, core issues and constraints, and to make recommendations for programme development and research.
