Measuring recovery in health-related quality of life during and after pulmonary exacerbations in patients with cystic fibrosis
Abstract
BACKGROUND: We explored the time-dependent impact of pulmonary exacerbations (PEx) on health-related quality of life (HRQoL) using Cystic Fibrosis Questionnaire-Revised (CFQ-R) data from 2 large cystic fibrosis (CF) trials.
METHODS: This exploratory post-hoc analysis evaluated the impact of PEx on CFQ-R domains of functioning in 80 patients with CF (homozygous for F508del-CFTR), aged ≥14 years randomized to placebo in the TRAFFIC and TRANSPORT trials who experienced 1 PEx.
RESULTS: Scores on the CFQ-R were significantly lower within 1 week of PEx start in 8 out of 12 domains (Respiratory Symptoms, Physical Functioning, Emotional Functioning, Health Perceptions, Role Functioning, Social Functioning, Eating, and Vitality). Patients whose PEx was treated with hospitalization or intravenous antibiotics had greater reductions in some domains of HRQoL compared with those treated with oral antibiotics. In the immediate weeks post-PEx, improvement was seen on Emotional Functioning, Respiratory Symptoms, and Health Perceptions, while further decline was seen for Eating, Physical Functioning, Role Functioning, Vitality, and Weight. For some measures (Physical Functioning, Vitality), full recovery to pre-PEx levels took several weeks.
CONCLUSIONS: Pulmonary exacerbations have significant effects on multiple domains of HRQoL, and recovery across multiple domains post-PEx can take several weeks. These findings provide insight into the impact of PEx on patient HRQoL and recovery post-PEx.…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 80 participants or records.
