Rapid Technology Scan: Pulmonary Function Tests (PFTs) and the Prevention of the Generation of Aerosols

Lung function testing has the potential to generate aerosols due to the test frequently provoking a cough after the procedure. Due to the COVID-19 pandemic lung function testing was paused creating a backlog. The Innovation Observatory performed a global horizon scan of respiratory technologies in May 2021, to identify the pipeline of innovations in development with the potential to restore lung function testing in primary, secondary and community settings.

The Innovation Observatory performed a scan of respiratory technologies that prevent/mitigate aerosol generation in May 2021, using robust horizon scanning methods to identify promising innovations and to anticipate technological trends.

We developed a detailed dataset of technologies by formulating search strategies for respiratory technologies, based on a comprehensive list of terms and input from expert panels. Primary and secondary sources were systematically scanned using a combination of traditional scanning methods, automated and novel AI/machine learning techniques.

Sources included clinical trial registries, MedTech news, academic sources, funding agencies, commercial sites and regulatory authorities. Together the insights provide a comprehensive landscape to allow decision-makers and HTAs to consider the clinical, financial, infrastructural and logistical provisions to improve preparedness for the potential adoption of these innovations.
