The HIA procedure
5. Evaluation and monitoring
Evaluating whether the HIA has influenced the decision making process (and the subsequent proposal) is an important component of HIA. As with any intervention, evaluation is required to see if it has worked. Evaluation of the HIA process is also useful to answer why the HIA worked (or not).
Monitoring the implementation of the proposal is critical to ensure that any recommendations that decision-makers agreed to, actually occur. Longer term monitoring of the health of populations is sometimes a component of larger proposals. This long term monitoring can be used to see if the predictions made during the appraisal were accurate, and to see if the health, or health promoting behaviours, of the community have improved.
