Room: Poster Hall
Background: Contamination of portable medical equipment such as wheelchairs may contribute to spread of healthcare-associated pathogens. The Hubscrub Medical Equipment cleaning system is a portable device used for cleaning of wheelchairs and other medical equipment. Users can choose a single wash and rinse cycle, a 3 minute UV-C cycle, or a combination of both cycles.

Methods: We examined the efficacy of the Hubscrub System in reducing Clostridium difficile spores, methicillin resistant Staphylococcus aureus (MRSA) and carbapenem resistant Escherichia coli (CRE) innoculated on steel disc carriers or on surfaces on wheelchairs. We also examined reduction of pathogen contamination on in-use wheelchairs.

Results: The wash cycle alone reduced C. difficile contamination by 2.6-3.6 log10 CFU and CRE by 4log10; the addition of the UV-C cycle resulted in an additional 0.5 log10 reduction. Forty percent of in-use wheelchairs were contaminated with C. difficile and/or MRSA. The 3 minute UV-C cycle eliminated MRSA contamination and reduced C. difficilecontamination by 33.3%.

Conclusion: The Hubscrub System was effective in reducing C. difficile spores, MRSA and CRE from wheelchair surfaces. The UV-C cycle enhanced the reduction of pathogens achieved by the wash cycle and may be useful as a standalone disinfection cycle for sensitive equipment.
