have a large eet on hand, and therefore if steriliation 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 sterilied, because not all processing takes place in the CSSP. “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 steriliation respectively. Many probes cannot withstand steriliation 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 CSSP,” r. Burdach added. “This presents a challenge because of the diverse groups involved in processing.” “CSSP 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 CSSP professionals use H or steriliation 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- iers 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 sterilie much of our instrumentation, items that can- not tolerate certain processes or have not been validated for steriliation are disinfected us- ing H.” Cenorin offers an alternative H process
that doesn’t require chemicals pasteuria- 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 pasteuried 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

for cleaning and high-level disinfection of reusable semi- critical and non-critical medical devices such as those used for anesthesia, pul- monary procedures,
sleep labs and respiratory care. It is A cleared and meets A bactericidal stan- dards for H. The 10 system is fully automated and provides a record of each cleaning and disinfection cycle. equiring only water and heat, this system eliminates the need for chemicals and their required user and patient protections. It is also an environmentally sensitive alternative since it discharges only water and nontoxic efuents into the medical waste stream.
Cleaning is critical egardless of the modality H or steril- iation a device won’t be safe for use unless it has been properly cleaned according to the manufacturer’s IU. “My major concern is the over-emphasis
that steriliation will solve all our issues,” said Nancy Chobin, N, AAS, ACSP, CSPM, CE, President, Sterile Processing University. “ I firmly believe we should be dedicating as much if not MOE attention to the training, certification and competencies for individuals performing these activities, especially compliance with manufacturer’s IUs for cleaning.
