A personalized asthma self-management plan, including a temporary quadrupling of inhaled glucocorticoid doses during symptom worsening, significantly reduced severe asthma exacerbations in adults and adolescents. This approach offers a proactive strategy for better asthma control.
Area of Science:
- Pulmonology
- Clinical Medicine
- Pharmacology
Background:
- Asthma exacerbations pose significant risks, including fatality.
- Current management often relies on reactive strategies.
- A proactive approach using personalized self-management plans is being investigated.
Purpose of the Study:
- To evaluate the efficacy of a self-management plan incorporating a temporary dose increase of inhaled glucocorticoids for managing asthma control.
- To determine if this strategy reduces the incidence of severe asthma exacerbations in adults and adolescents.
Main Methods:
- A pragmatic, unblinded, randomized trial was conducted over 12 months.
- Participants received inhaled glucocorticoids and were randomized to a self-management plan with (quadrupling group) or without (non-quadrupling group) a fourfold temporary increase in inhaled glucocorticoid dose.
- Severe asthma exacerbation was defined as systemic glucocorticoid treatment or unscheduled healthcare consultation.
Main Results:
- A total of 1922 participants were randomized, with 1871 in the primary analysis.
- The quadrupling group experienced fewer severe exacerbations (45%) compared to the non-quadrupling group (52%), with an adjusted hazard ratio of 0.81 (P=0.002).
- Adverse effects, mainly local, were more frequent in the quadrupling group.
Conclusions:
- A personalized asthma self-management plan with a temporary quadrupling of inhaled glucocorticoid dosage effectively reduces severe asthma exacerbations.
- This strategy provides a proactive method for improving asthma control in adults and adolescents.
- While effective, potential increases in local side effects should be considered.
