[The WHO's international classification of functioning, disability, and health (ICF): essential knowledge for nurses]

Taiwan's increasingly aging population has increased demand for elderly and long-term care dramatically. Professional competency based on the latest information and best-practice techniques is essential for nurses to provide high-quality care. As of 2012, the Protection Act for the Rights and Interests of Disabled Citizens requires that healthcare providers evaluate level of disability according to the WHO's International Classification of Functioning, Disability and Health (ICF). Professional nurses thus must fully understand the ICF. This article introduces ICF concepts as well as its development, coding system, core sets, and application. We also introduce a case situation to illustrate ICF coding methodology. This article is intended to raise awareness of the ICF evaluation approach and facilitate its quick and proper application in clinical work and guidance on best-practice nursing interventions.
