Assessment of functional outcomes in patients with head and neck cancer according to the International Classification of Functioning, Disability and Health Core Sets from the perspective of the multi-professional team: results of 4 Delphi surveys.

BACKGROUND: The International Classification of Functioning, Disability and Health Core Set for Head and Neck Cancer (ICF-HNC) covers the typical spectrum of problems in functioning in head and neck cancer. This study is part of a multistep process to develop practical guidelines in Germany. The purpose of this study was to identify instruments for the assessment of functioning using the ICF-HNC as reference.

METHODS: Four Delphi surveys with physicians, physiotherapists, psychologists, and social workers were performed to identify which aspects of the ICF-HNC are being treated and which assessment tools are recommended for the assessment of functioning.

RESULTS: Ninety-seven percent categories of the ICF-HNC were treated by healthcare professionals participating in the current study. Altogether, 33 assessment tools were recommended for therapy monitoring, food intake, pain, further organic problems/laboratory tests, and psychosocial areas.

CONCLUSION: Although the ICF-HNC is being currently implemented by the head and neck cancer experts, several areas are not covered regularly. Additionally, validated tools were rarely recommended.
