Summary
Effective asthma management involves prompt treatment of severe attacks with inhaled beta-agonists and oral steroids. Long-term prevention relies on inhaled corticosteroids (ICS) and educational programs, avoiding high-dose ICS when possible.
Area of Science:
- Pulmonology
- Evidence-Based Medicine
- Health Economics
Background:
- Asthma management requires cost-effective strategies.
- Randomized controlled trials (RCTs) provide evidence for treatment efficacy.
- Optimizing patient education and medication regimens is crucial for chronic disease control.
Purpose of the Study:
- To determine a cost-effective strategy for bronchial asthma management.
- To synthesize evidence from RCTs to guide clinical practice.
- To identify optimal approaches for acute and long-term asthma care.
Main Methods:
- Systematic review of randomized controlled trials.
- Analysis of treatment protocols for acute severe asthma.
- Evaluation of long-term prevention strategies, including pharmacotherapy and education.
Main Results:
- Acute severe asthma requires short-acting inhaled beta-agonists and oral steroids, with timely hospital admission decisions.
- Comprehensive, specialist-led educational programs with self-monitoring improve outcomes.
- Low-dose inhaled corticosteroids (ICS) are the most cost-effective long-term prevention; add-on oral bronchodilators are preferred over high-dose ICS or long-acting inhaled beta-agonists.
Conclusions:
- A cost-effective asthma management strategy integrates prompt acute care with intensive, personalized education.
- Low-dose ICS form the cornerstone of long-term asthma prevention, supplemented by oral bronchodilators when necessary.
- Avoiding prolonged emergency department stays and high-dose ICS optimizes patient outcomes and resource utilization.
