Supplementary Material for: Single-Use or Disposable Flexible Bronchoscopy in Advanced Bronchoscopy Procedures: Experience in a Quaternary Referral Centre

<b><i>Background:</i></b> The development of single-use flexible or disposable bronchoscopes (SUFBs) has accelerated in recent years, with the reduced risk of infectious transmission and reduced need for endoscopy staffing particularly advantageous in the COVID-19 pandemic era. <b><i>Objective:</i></b> The objective of this study was to assess the performance of a novel single-use bronchoscope in an academic quaternary referral centre with on-site interventional pulmonology programme. <b><i>Methods:</i></b> With ethical approval in a quaternary referral centre, we prospectively collected data on sequential bronchoscopy procedures using The Surgical Company Broncoflex© range of SUFBs. Data collected included demographic, procedural, scope performance, user satisfaction, and complication parameters in a tertiary bronchoscopy service. <b><i>Results:</i></b> 139 procedures were performed by five pulmonology faculty from January to July 2021. The majority were carried out for infection (45%) and malignancy (32%). Most were performed in the endoscopy suite and 8% were COVID positive or suspected. Most procedures reported the highest score in satisfaction (85%) with technical limitations reported in 15% (predominately related to scope suction or inadequate image quality) reverting to a reusable scope in 2.8 %. <b><i>Conclusion:</i></b> In our subset of patients in a bronchoscopy unit, SUFBs are safe, and both routine and advanced bronchoscopy procedures can be performed with high satisfaction reported.
