The approach in this framework is that the basis of measurement is each contact with the health system, and not the entire duration of the disease or health condition. A contact is distinct from the complete treatment, which comprises all the contacts to treat a health condition. At this stage, interventions aim to enhance health status and to maintain a condition of low risk of diseases, disorders or injuries - in other words, to prevent their occurrence (HC.6), through vaccinations or an injury prevention programme, for example.
