Reprocessing Steps

Wearing personnel protective equipment (PPE) protects you against transmission of pathogens during pre-cleaning and the pre-cleaning prepares the instrument for further reprocessing.

Ensure that your instrument is pretreated immediately after use. Although effective against
SARS-CoV-2, under no circumstances use alcohol, chlorine or aldehyde wipes or solutions during pre-cleaning due to their fixative properties.
The efficacy of all following cleaning, disinfection and sterilization steps may be affected.

The transport of the (pretreated) device from the examination room or the operating room to the reprocessing area should be undertaken in a closed basket or container (for example in the in case of flexible endoscopes, the Olympus ETS Plus). This eliminates the risk of microbial transmission (including SARS-CoV-2) to the environment or healthcare personnel.

Wearing personnel protective equipment (PPE) protects you against transmission of pathogens during cleaning and sufficiently prepares the instrument for further reprocessing. Due to its large size and envelope, SARS-CoV-2 is very prone to chemical and physical attack.

Notification Chemicals Used during Reprocessing

Although SARS-CoV-2 is a novel virus, it is widely assumed that it does not react differently to chemicals than other microorganisms. Therefore the use of the same agents in the same concentrations and contact times as usual is recommended, unless otherwise instructed by the manufacturer of the chemicals. In case you use chemistry or processes for reprocessing not mentioned in the IFU, consult the respective manufacturer for further advice or follow your local rules.

As described in the instructions for use (IFU), the outer surfaces, crevices and channels (if applicable) need to be carefully and thoroughly brushed or wiped while the instrument is fully immersed.

This avoids unintentional splashing of liquids and infectious microorganisms in the reprocessing area.

For heat-sensitive instruments like flexible endoscopes, the use of an EWD (such as the Olympus ETD or OER systems) is regarded as the most effective measure with regards to personnel safety and microbiological (including virucidal*) efficacy.

Check the labeling on your disinfectant.
“Limited virucidal*” (= effective against enveloped viruses) or “full virucidal*” (= effective against enveloped and naked viruses).
Therefore even disinfectants labeled as “limited virucidal” are effective against SARS-CoV-2.

Olympus EndoDis and Olympus Disinfectant have been validated according to EN 14476 and EN 17111 under the process conditions of the Olympus ETD machines and demonstrated comprehensive virucidal efficacy. Consequently, they can be regarded as effective against all relevant viruses in the healthcare field according to the latest state of science, including enveloped viruses (the Covid-19 virus is an enveloped virus).

For OER-AW, Acecide-C has been validated according to required national guidelines for high level disinfectants and has been confirmed to quickly inactivate even non-enveloped viruses such as adenovirus and poliovirus, which are known to demonstrate higher resistance than enveloped viruses. Therefore, Acecide-C is considered to be effective against the novel coronavirus, the Covid-19 virus.
In case you use non-Olympus chemistry or processes for reprocessing, consult the respective manufacturer for further advice.

Like many other enveloped viruses, SARS-CoV-2 is known to be very sensitive to heat.
Therefore for heat-stable instruments, even when applying an A0 value of 600 in the thermal disinfection phase, SARS-CoV-2 is rapidly and completely inactivated.

Wearing personal protective equipment (PPE) protects you against transmission of pathogens during disinfection and sufficiently prepares the instrument for further handling and (if applicable) sterilization.

Due to its large size and envelope, SARS-CoV-2 is very prone to chemical and physical attack.

Disinfectants with virucidal* efficacy are effective against SARS-CoV-2. Therefore check the virucidal efficacies of your validated disinfectant and apply the respective concentrations and contact times indicated on its label or data sheet. As stated in the IFU, instruments urgently need to be completely immersed for disinfection so that the disinfectant contacts all relevant surfaces.

According to international healthcare organizations such as the World Health Organization (WHO) and best practice recommendations, the use of disinfectants based on alcohol, sodium hypochlorite and hydrogen peroxide are most commonly used for effective surface disinfection. However, the materials of Olympus generators, light sources, trolleys and other equipment may vary, so please follow the instrument’s and the disinfectant’s instructions for use.

Room Disinfection

For Olympus equipment, room disinfection by dispersing or spraying disinfecting agents such as an aerosol with a fogger into a fully equipped examination or operating room, is not recommended. These small droplets may get into the housing of electrical equipment and cause electrical shortages and damage to the equipment.

Therefore for heat-stable instruments, even when applying an A0 value of 600 in the thermal disinfection phase, SARS-CoV-2 is rapidly and completely inactivated.

If disinfection has already been carried out before sterilization, the complete SARS-CoV-2 load is already inactivated. In the case of instruments classified as “critical” due to their intended use, a final sterilization step must be performed.

Where only a cleaning step is carried out before sterilization, SARS-CoV-2 will be inactivated by any validated type of sterilization method, although steam sterilization is always the preferred method for heat-stable devices.

In case you use sterilization processes not mentioned in the IFU, consult the respective manufacturer for further advice or follow your local rules.
