 The study aimed to link international classification of functioning, disability, and health, ICF, categories to interstitial lung diseases, ILDs, resulting in 111 identified ICF categories for 10 patient reported outcome measures, PROMs, and three traditional objective measures. 34 new personal factors emerged, providing insight into the utility of the ICF in lung disease and possibilities for developing more streamlined instrumentation. The study highlights the importance of familiarity with the ICF in ILD as it prepares for the imminent harmonization of international classification of diseases, ICD, and ICF, ICD-11.
