Hypothesis
Do asthma exacerbations affect changes in patient-reported outcome measures (PROMs) over time, and can asthma-specific PROMs predict exacerbations in adults with severe asthma?
Conclusion
PROMs are significantly impaired in patients with severe asthma, and asthma exacerbations are key drivers of changes in these measures.
Supporting Evidence
- Patients with no exacerbations showed significant improvement in PROMs.
- Patients with more than two exacerbations experienced a deterioration in PROM scores.
- Baseline ACQ5 was a predictor of exacerbations with low diagnostic accuracy.
Takeaway
This study shows that when asthma patients have flare-ups, their reported quality of life gets worse, but those without flare-ups feel better over time.
Methodology
Data from 421 patients with severe asthma were analyzed, focusing on various PROMs assessed at baseline and after 12–18 months.
Potential Biases
The PROMs used were not specifically developed for severe asthma, which may affect their accuracy.
Limitations
Data collection was limited to only two time points, which restricts the ability to identify fluctuations in symptoms.
Participant Demographics
62% female, mean age 51.9 years, 39% obese.
