再利用可能および使い捨て気管支鏡の費用分析モデル：介入的肺医学ユニットにおける手技量、フリートサイズ、およびデバイスタイプの関係

Reusable flexible bronchoscopes (RFB) and single-use flexible bronchoscopes (SUFB) are clinically equivalent. Economic evaluations are essential due to rising health care costs. This study aims to compare the costs of the procedure with RFBs or SUFBs, considering major factors such as procedure volume, fleet size, and SUFB model.

This single-center, observational study at Rouen University Hospital evaluated RFB costs (equipment, maintenance, and reprocessing) and SUFB costs (purchase and disposal). A micro-costing approach was used to estimate costs, with sensitivity analyses examining the impact of procedure volume and fleet size on costs.

The total cost per procedure with RFBs was €195.72 in the endoscopy room and €231.48 in the operating room. The median cost for SUFBs was €245 (range: €208 to 336, depending on the model). RFBs became cost-effective over SUFBs if at least 913 bronchoscopies are performed annually. This threshold varies according to the RFB fleet, and the SUFB model.

This study highlights that RFBs are more cost-effective than SUFBs in high-volume settings. Therefore, the choice between RFBs and SUFBs should consider the facility's specific conditions, such as procedure volume and available equipment. A hybrid approach, using both devices, may be beneficial in settings with varying procedural demands.
