BACKGROUND
Cystic fibrosis (CF) specific patient-derived and reported symptom tools are critical steps toward evaluating the outcomes of new therapies for CF.
METHODS
We conducted 25 in-depth qualitative interviews using the Day Reconstruction Method and 9 cognitive interviews at two CF programs, the University of Washington and Seattle Children's Hospital and Regional Medical Center. The interviews were audio-recorded and transcribed, and then coded and analyzed for themes relating to pulmonary symptoms and related psychosocial impacts.
RESULTS
Six pulmonary symptoms were identified as central to CF: cough, sputum production, wheeze, chest tightness, difficulty breathing/shortness of breath, and fever. Emotional impacts included frustration, sadness/depression, irritability, worry, difficulty sleeping; while activity impacts included time spent sitting or lying down, reduction of usual activities, and missing school or work. In all, 8 symptom items, 4 emotional impacts items, and 4 activity impacts were selected for inclusion on a new daily diary. We also assessed triggers for seeking care.
CONCLUSIONS
Using a qualitative inductive methodology, we have obtained patient centered data regarding pulmonary symptoms and burdens and have created a novel patient reported outcome measure for CF. Future studies will assess the validity of the instruments.
