Does the Comprehensive International Classification of Functioning, Disability and Health (ICF) Core Set for rheumatoid arthritis capture nursing practice? A Delphi survey.

BACKGROUND: The "Comprehensive ICF Core Set for Rheumatoid Arthritis (RA)" is an application of the International Classification of Functioning, Disability and Health (ICF) and represents the typical spectrum of problems in functioning of patients with RA.

OBJECTIVES: The objective of this study was to validate this ICF Core Set from the perspective of nurses.

METHOD: Nurses experienced in RA treatment were asked about the patients' problems, patients' resources and aspects of environment that nurses take care of in a three-round survey using the Delphi technique. Responses were linked to the ICF.

RESULTS: 57 nurses in 15 countries named 1170 concepts that covered all ICF components. 20 concepts were linked to the as yet undeveloped ICF component Personal Factors. 19 ICF categories are not represented in the Comprehensive ICF Core Set for RA.

CONCLUSION: The validity of the Comprehensive ICF Core Set for RA was largely supported by the nurses. However, a number of body functions which address side effects of drug therapies were not included in the Comprehensive ICF Core Set for RA. Furthermore, several issues arose which were not precisely covered by the ICF like "dry mucous", "risk for decubitus ulcers" and "height" and need to be investigated further.
