The concepts and terminology of the International Classification of Functioning (ICF) are compatible with interdisciplinary practice and a focus on health and function of each individual. The National Academies of Practice (NAP) supports the use of ICF language and terminology in practice guidelines, standards of practice, curriculum development, public policy, international relations, and research.
The ICF integrates the social and environmental aspects of health, illness and disability. It provides a framework that is applicable to mental and physical disorders. The ICF focuses on function rather than illness and diagnosis.
NAP endorses the use of the ICF for tracking individual and population health and function. The ICF framework holds great potential to address issues of the ageing population in the United States as well as a mechanism for medical review and allocation of expenditures for interventions that promote healthy functioning of the population.
