Surveillance, monitoring and evaluation
Monitoring and evaluation are essential components of the work of WHO's Global Malaria Programme (GMP). Monitoring measures the implementation of the range of strategic activities, while evaluation measures the extent to which its objectives are being reached.
Many organizations use different indicators and methodologies to collect malaria data, contributing to the overall problem of monitoring malaria trends. The potential of existing health information systems (HIS) in malaria-endemic countries is not being fully exploited to enable accurate measurement of intervention coverage and impact.
GMP's role is to provide guidance to improve country HIS inputs, including development of new surveys and tools that vastly improve the accuracy of information collected and that place greater emphasis on community and facility information systems.
In order to accurately estimate the burden of disease and measure the trends in malaria, greater coordination, better survey instruments and methods are being developed.
Monitoring is a continuous on-going activity. It allows step-by-step recording of the progress made by health programmes.
Monitoring, which measures process indicators, should be carried out at district, as well as at provincial, national, regional and global levels. Apart from ensuring that activities are being implemented in the agreed manner, it allows decision-makers to stay aware of all problems and constraints which may slow down progress and provide the information they may need to refine their planning.
