7.5 Evaluation of the response | Guías de práctica clínica MSF

Contenido

The evaluation can be exhaustive (analysis of each activity and strategies) or focus on certain activities and/or strategies.
It examines different aspects: effectiveness, accessibility, responsiveness, safety and quality, and resource mobilisation.

As soon as the intervention begins, define the objectives and indicators, make sure that the tools needed to collect the data are available and that the personnel are trained in using them.

Some indicators are collected routinely throughout the outbreak. Others are collected during field visits at a sample of health care facilities or vaccination sites, according to a specific methodology and with specific tools established at the start of the intervention. The information is compiled and analysed when the epidemic is over.

A final intervention evaluation report is written and presented to the epidemic management committee. It is a critical analysis of the operations conducted and offers recommendations for improving the next response. It is based on the evaluation tables below.
