Room: The Pennsylvania Convention Center: IDExpo Hall BC

Background: Wheel chairs are high-touch surfaces that frequently become contaminated with healthcare-associated pathogens, including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and Clostridium difficile.. Because these items are frequently shared between patients, there is a need for effective and efficient disinfection methods. STERIPLEX SD is an EPA-registered cleaner and disinfectant with sporicidal activity for use on hard and soft surface.

Methods: We tested the hypothesis that spraying wheel chair surfaces in healthcare facilities with peroxyacetic acid disinfectant using an electrostatic sprayer would reduce bacterial burden on surfaces that are challenging to clean with other solutions. To evaluate efficacy in our facility, we treated 64 wheelchairs (95 sites) in patient rooms, escort services, and outpatient clinics with STERIPLEX SD with sampling before and after application.

Results: On wheelchairs, application of STERIPLEX SD resulted in reduction of C.diff (30/64; 47% versus 1/64; 2%). Wheels were more frequently contaminated with C.diff (13/31; 42%) than the body of the wheelchair (7/35; 20%). Positive body cultures were reduced from 20% to 0% and positive wheel cultures were reduced from 42% to 3% following application of STERIPLEX SD. MRSA was recovered on 1 of 64 wheelchairs and VRE was not recovered from any wheelchairs.

Conclusion: Our results provide evidence that spraying wheelchairs with a peroxyacetic acid solution may be a simple and effective means to reduce contamination with healthcare-associated pathogens. It appears that decontamination and the potential of wheelchairs as a reservoir for healthcare-associated pathogens is under-valued and may be a significant source of contamination to patient, staff, and visitors.
