A new training system for the supraglottic index (SGI) allows bronchoscopists to reliably score laryngopharyngeal reflux (LPR) and aspiration in refractory asthma patients, improving diagnosis and treatment.
Area of Science:
- Pulmonology
- Gastroenterology
- Otolaryngology
Background:
- Refractory asthma is often linked to laryngopharyngeal reflux (LPR) and aspiration, hindering effective management.
- A previously developed supraglottic index (SGI) aids in evaluating LPR with potential aspiration.
Purpose of the Study:
- To develop and assess a teaching system for the SGI scoring system.
- To improve the interobserver and intraobserver reproducibility of SGI assessments by bronchoscopists.
Main Methods:
- Five pulmonologists, new to the SGI, underwent training using an internet-based system.
- The system was designed for widespread accessibility and interactive learning.
Main Results:
- Excellent interreader agreement (κ ≥ 0.81) was achieved by the final testing, confirming scoring reproducibility.
- High intrareader consistency was demonstrated with a κ value of 0.93 (95% CI: 0.79–1.00) upon retesting.
Conclusions:
- An organized educational approach enables bronchoscopists to reproducibly assess and score supraglottic abnormalities using the SGI.
- The SGI can identify patients requiring further intervention for LPR and gastroesophageal reflux, facilitating personalized therapy for refractory asthma.
