    Dear All,

    This study will be of interest to healthcare facilities using reusable
    transvaginal and transrectal ultrasound probes.

    The poster was presented at SHEA Spring 2015: Science Guiding Prevention
    Conference, May 14-17 2015, Orlando, Florida.

    The study looked at the effectiveness of two disinfectants commonly used for
    high level disinfection, glutaraldehyde and ortho-phthalaldehyde (OPA) and
    an automated high level disinfection system (see poster for product details)
    against human papillomavirus.

    The findings were as follows:

    * “An automated high level disinfection system was able to fully
    inactivate HPV16 and HPV18 under normal clinical use conditions
    (concentration, time, temperature).

    * Hypochlorite was more effective than OPA at reducing infectivity
    of HPV16 and HPV18, although complete inactivation was not achieved.

    * OPA is currently accepted as a HLD; hypochlorite is unsuitable for
    plastics used to manufacture endocavity ultrasound probes.

    * The findings suggest that a review of probe reprocessing methods
    and disinfection standards as related to HLD may be warranted”.

    Regards

    Glenys
