P075 Behind the mask: clinician practices for reprocessing PAP devices.

Abstract Introduction There are no evidence-based guidelines concerning reprocessing of positive airway pressure (PAP) devices between users. Consequently, current practices are based on local policies and interpretation of manufacturer instructions. Many PAP users start with loaned or rented equipment, so understanding PAP device hygiene is an urgent priority. Little is known about reprocessing procedures across Australia. Methods An online anonymous survey was administered to clinicians involved in reprocessing PAP devices between users. This survey was sent to both targeted clinicians known to provide non-invasive ventilation (NIV) and openly circulated via mailing lists to clinicians managing PAP devices, to understand current practices. Results Response rate was 41% (20/49) for targeted respondents, with a total of 66 completed responses. 53% of respondents had more than 10 years of experience and most provided NIV (institutional, 83%; home 89%). Confidence in NIV machine reprocessing in institutions was 77.3 (SD 18.9) on a 100mm visual analogue scale (VAS). Less than 30% of respondents described alternate cleaning processes for known multi-resistant organisms (MROs). A device isolation period before re-issue occurred at 26% of sites providing home NIV. Thematic analysis identified waste concerns due to mandated single use items, uncertainty about MROs and evolving requirements for tracking of equipment. Discussion This is the first known survey investigating PAP reprocessing practices by experienced clinicians, showing limited procedural variability and variable confidence in reprocessing procedures used. Evidence-based guidelines are needed to further homogenise cleaning practices especially around MROs, while integrating both risk mitigation and principles of sustainable healthcare.
