The benefits of a home non-invasive ventilation retrieval service: Improved effectiveness and environmental sustainability in challenging times.

In the last 6 months, home non-invasive ventilation (NIV) services have faced several unanticipated challenges to their effectiveness and delivery as the result of a 'perfect storm' of the COVID-19 pandemic demands. We developed and delivered an innovative follow-up service, to support home NIV delivery, and improve cost-effectiveness and sustainability during COVID-19. Between Feb-2019 and Nov-2020, 92 post-acute patients were issued with home NIV; 25 (27%) out of the 92 patients had unused NIV machines successfully retrieved. The median (IQR) days of home NIV usage were 207 (98) for patients who had their machines returned. All the unused NIV machines retrieved were within the 5-year working life guaranteed by the manufacturer and were all redeployed after appropriate reconditioning and infection control measures. Without the home-visiting and recycling pilot, we would have relied on patients and families to return the unused machines. Given the expected disruption to NIV machine supply for at least the foreseeable 12-18 months, we feel it is important to get this important message out to other home NIV services urgently. Wider implementation of this novel approach could increase the availability of this vital resource and help meet the current demand on home NIV services.
