Fundamentals / Key principles

Only clean medical device canbe disinfected or sterilized

Standardized and validated cleaningprocesses are required for ALL MD

Validated Cleaning?

Validationdocumented procedure for obtaining, recording and interpreting the results required to establish that a process will consistently yield product complying with predetermined specifications. (from EN ISO 15883-1)

Standardization of processesis a necessary precondition for validation of a cleaning process.How you would otherwise guarantee that the process will CONSISTENTLY yield results as specified?

13 WFHSS | 05.10.2017 | Auly & Denis |

Why such a challenge?

Wide variety of instruments: different shapes, lengths, diameters, connections..

Complex design

Continuous in-put of new devices

14 WFHSS | 05.10.2017 | Auly & Denis |

Why such a challenge?

Visual control of every instrumentis impossible…Is it clean?

Example of a reamer Video F.Cavin

Needs the help of devices for aided visual inspection

….it still depends too much on the individual technician!

Critical analysis of IFU

IFU do not help the standardization

Positive provide information

(according ISO 17664)

Assumption is that manufacturer knowshis instrument best

Indications on dismantling

Manufacturer has to provide an adequate reprocessing method

Negative Main concern = keep the MD

functional

Lack of knowledge regarding the organization of a CSSD and the guidelines

Recommend numerous ways of cleaning not compliant with the guidelines

Manual cleaning is the most frequentrecommendation

Are they validated? According to what?

30 WFHSS | 05.10.2017 | Auly & Denis |

Take home message

At the moment it is very hard to implement a cleaning processthat deserves to be called «validated» for all cannulatedinstruments of a given CSSD

Lack of standardization Dependency on human factor

Too frequently relying onIFU instead of expertise

Connect every lumen instrument

Ensure Cleaning Efficacy(inside & outside)

Avoid particles to get into lumens

Facilitate standardization

Only one instrument did not pass the test

Due to the use of the wrongconnector

Conclusion: Make sure you reallyuse the right connector for everytype of instrument

The jet must be longer than the instrument

To summarize the testing

Mix Rack and connectors provide a solution for a majority of instruments

Quick flexibility is proven

Cleaning efficacy

Human factor is limited by reduction of manual cleaning

But still present: Choice of the right connector

Different ways to lay out all the instruments of the set

Still not 100% standardized yet…

Take Home Messages

In reality standardized cleaning of cannulated instruments is muchmore difficult to implement than for non cannulated instruments

Discussion of current cleaningstrategies … and their weaknesses

Dependency of human factor is a barrier for standardization and thusfor validation
