The results of a new study support the importance of low-level disinfecting reusable oxygen nipple and nut adaptors (i.e., "Christmas tree adaptors") between patients.

For the study, which was published in The Society for Healthcare Epidemiology of America's Infection Control & Hospital Epidemiology, researchers examined the effectiveness of using disinfection wipes to eliminate bacteria from the devices. They tested two different types of wipes: 1) 0.5% hydrogen peroxide and 2) 0.25% tetra-ammonium chloride with 44.50% isopropyl alcohol.

The result: Both wipes effectively removed bacteria, leading the researchers to conclude: "Low-level disinfection of Christmas tree adaptors is appropriate prior to redeployment in the clinical setting."

ICCS urges providers to follow manufacturer recommendations for all medical devices as many Christmas tree adaptors are single-use and cannot be disinfected and reused. See this infection prevention tip on single-use versions.
