The World Health Organizations International Classification of Functioning, Disability and Health (ICF) is the internationally accepted standard for assessing, documenting, and reporting functioning and disability. The ICF Core Sets highlighted in this second edition of the book have been developed to facilitate the standardized use of the ICF in real-life clinical practice. Consequently, they can guide clinical quality management efforts. This edition has been updated to reflect developments in the ICF Core Sets, including updated information on eight new Core Sets and the Generic Sets, the new ICD-11 codes, more details on the Core Set development process, and a new section on ICF-based tools.
