Introduction: The International Classification of Functioning, Disability and Health (ICF) provides a standardised language and conceptual framework for health and health-related conditions, aiming to unify communication between different disciplines.
Objective: To describe the process of selecting (through national expert consensus) ICF categories representative of functioning problems in cancer patients at hospital discharge.
Method: We conducted a descriptive qualitative and quantitative study that used the expert consensus method to design a clinical instrument. The study included 21 experts, consisting of 2 patients and 19 health professionals from different disciplines. A total of 208 ICF categories obtained in a previous stage through a systematic review and linking process were evaluated in 3 rounds. Participants evaluated each code and classified it as: highly relevant, relevant, slightly relevant, and not relevant at all. Only those codes assessed as «highly relevant» by more than 50% of the experts were included (cut off). In addition, another 143 ICF categories were evaluated in the second round.
Results: In all, 24 ICF categories were obtained: 10 corresponded to the body function component, 11 to activities and participation, and 3 to environmental factors.
Conclusions: Consensus using the common language of the ICF resulted in the selection of 24 representative categories of the main health problems related to functioning at hospital discharge in adults treated for cancer.
