Abstract
Background: Further validation of K-BILD questionnaire content is needed in PF-ILD.
Aim: Assess relevance and comprehension of K-BILD questionnaire content in PF-ILD.
Methods: 20 adult ILD patients (US [n=15]; Germany [n=5]) with prespecified PF-ILD criteria (eg, ≥10% relative decline in FVC%pred) were interviewed. After concept elicitation, participants completed the 15-item K-BILD questionnaire assessing 3 domains (breathlessness/activities, psychological and chest symptoms) within the past 2 weeks, followed by an interview. Interviews were audio-recorded, transcribed and coded for qualitative content analysis using ATLAS.ti.
Results: Reporting values as median (range), participants were aged 73 (48–81) years with 67% (47–95) FVC%pred. Rheumatoid arthritis-associated (25%), hypersensitivity pneumonitis (20%) and other fibrosing (30%) ILD were amongst the underlying ILD diagnoses for this cohort. Breathlessness was one of the most frequent and impactful K-BILD items reported by patients. Comprehension of K-BILD time period was high, with most participants stating they were thinking of the past 2 weeks (n=14/20, 70%) and 100% (n=19/19) reporting ability to recall 2 weeks’ time. K-BILD items were well understood by participants, capturing relevant aspects of PF-ILD affecting most participants (Figure).
Conclusion: For patients with PF-ILD, K-BILD is well understood and contains relevant concepts.
