Implementation of Bronchoscopic Lung Volume Reduction Using One-Way Endobronchial Valves: A Retrospective...

Area of Science:

• Pulmonology
• Interventional Pulmonology
• Respiratory Medicine

Background:

• Bronchoscopic lung volume reduction (BLVR) using 1-way endobronchial valves (EBV) is a guideline treatment for advanced emphysema.
• Real-world data on BLVR implementation in hospitals is limited.
• Understanding conditions for successful BLVR programs is essential.

Purpose of the Study:

• Evaluate the eligibility rate for BLVR in an academic hospital setting.
• Assess the feasibility and clinical outcomes of implementing BLVR with EBV.
• Determine the sustainability of a BLVR program.

Main Methods:

• Retrospective evaluation of patients treated with EBV (January 2016 - August 2019).
• Assessment of COPD Assessment Test (CAT), FEV1, RV, and 6-min walking test (6MWT) at baseline and 3 months.
• Paired sample t tests used for statistical analysis.

Main Results:

• Only 16% of 350 screened patients were eligible for EBV intervention.
• 45 patients completed 3-month follow-up, showing significant improvements in CAT, FEV1, RV, and 6MWT (all p < 0.001).
• 76% of patients had valves in situ after 1 year.

Conclusions:

• BLVR with EBV is a feasible and effective treatment for a highly selected group of advanced emphysema patients.
• The low eligibility rate highlights the need for a high volume of COPD patients for a sustainable BLVR program.
• Successful implementation requires careful patient selection and program management.
