have a large eet on hand, and therefore if steriliation was introduced it would further lengthen the turnaround time for reprocess- ing a scope.”


Where processing takes place When evaluating instrument or device pro- cessing, a healthcare facility must take into account where these items will be disinfected or sterilied, because not all processing takes place in the CSSP. “Ultrasound is now used in almost all hospital departments and across many clinics in a wide array of procedures,” said on Burdach, Ph, Head of Clinical Affairs, Nanosonics. “These probes are used in non- critical, semi-critical and critical procedures requiring low-level disinfection, high-level disinfection and steriliation respectively. Many probes cannot withstand steriliation processes and these instead undergo H and are used with a sterile sheath.” “It is an interesting space, because most ultrasound probes are processed in the de- partments in which they are used, outside of the CSSP,” r. Burdach added. “This presents a challenge because of the diverse groups involved in processing.” “CSSP staff members


may be consulted in set- ting up the disinfection processes, but the clinical staff members are usually responsible for performing the processing. The use of automated processors can help reduce human error in these settings and CS SP leadership have an important role in providing training and support to the clinical departments.”


Staff safety CSSP professionals use H or steriliation to kill


dangerous microorganisms  but what risks do they pose to the users? “The safety of our employees


is of the utmost importance, which is why all necessary pre- cautions are taken to ensure their wellbeing,” said ranklin. “Em- ployees that operate EtO steril- iers are monitored for exposure and access to the area is limited. All instruments are processed according to manufacturer’s recommendations and while we would prefer to sterilie much of our instrumentation, items that can- not tolerate certain processes or have not been validated for steriliation are disinfected us- ing H.” Cenorin offers an alternative H process


that doesn’t require chemicals  pasteuria- tion - which has been used to destroy po- tentially pathogenic organisms in the food and beverage industry for decades. As ic adford, CEO, Cenorin, explains, a medical device can be pasteuried by fully immers- ing it in heated water for a specific amount of time at a specific temperature to achieve microbial destruction. Heat from the water excites the molecular bonds within the organism structure, unfolding proteins and rendering them unable to survive. “Medical device standards
