The choice of indicators has closely followed some of the health measures considered by the Framework on Health Statistics developed by the Inter-Secretariat on Health Statistics (Box 5.1), though this framework is not yet wide-spread and would benefit from further use and development. The chapter does not deal with indicators of health input (e.g. health expenditure), output (e.g. number of interventions) or drivers (e.g. life style behaviour). The role of risk factors, such as smoking and alcohol use, is also not explicitly considered oris considered only to a limited extent (e.g. obesity).
