Can single-use bronchoscopes help prevent nosocomial COVID-19 infections?

Introduction: The reduction of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission has been achieved through numerous public health initiatives worldwide. In the hospital environment, certain high-risk procedures have the potential to cause transmission of the virus to health-care workers and nosocomial transmission to patients through different mechanisms including the generation of aerosols and fomite formation via contamination of medical devices. Areas covered: Aerosol-generating procedures such as bronchoscopy are considered high risk for SARS-CoV-2 transmission. As a result, single-use devices should be used where possible and changing to single-use flexible bronchoscopes has been advised by respiratory societies internationally. In this paper, we outline the rationale for this advice and have analyzed the evidence relating to the reduction in SARS-CoV-2 transmission arising from a switch to these single-use devices and the potential impact that this switch may have on the quality of pulmonology services.
