The Center for Disease Control (CDC) states: “Validation of the cleaning processes in a laboratory-testing program is possible by microorganism detection, chemical detection for organic contaminants, radionuclide tagging, and chemical detection for specific ions. During the past few years, data have been published describing use of an artificial soil, protein, endotoxin, X-ray contrast medium, or blood to verify the manual or automated cleaning process and adenosine triphosphate bioluminescence and microbiologic sampling to evaluate the effectiveness of environmental surface cleaning. At a minimum, all instruments should be individually inspected and be visibly clean. (see Guideline for Disinfection and Sterilization in Healthcare Facilities 2008 here).
The WashChecks Washer Monitor facilitates a red protein soil and a specifically designed holder to monitor cycle efficiency. If all the red is completely washed away after a test cycle, then it is a PASS and the washers disinfectors can be released for use. If there are any traces left of the red protein soil after a test cycle, then it is a FAIL indicating that the equipment or detergent is questionable and instruments may not be getting cleaned properly. See Pass/Fail chart above.
Do I Need a WashCheck Holder? The WashCheck Holder keeps the WashCheck monitor secure during the wash process. It is designed so that half of the protein soil area is covered by the holder, while the other half is exposed, simulating the joint of a surgical instrument and testing the indirect impingement of the washer disinfector.
Placement of the WashCheck Monitor
The WashCheck Holder and Monitor should be placed inside the basket with the red protein spot facing up towards the outside perimeter of the spray arms. It's recommended to place a WashCheck monitor on every shelf of the cart, to test the full cycle of the washer on every level.
What Does A FAIL Mean
Some possibilities are: A clog from dried chemicals or debris. Loose/broken or blocked spray arm. Or - a problem with the detergent used for that cycle. Repair or unclog the spray arms and redo the wash cycle.
Frequency of Testing
We recommend using WashCheck Monitors DAILY to test your Washers Disinfectors or Instrument Washer. Don’t go a whole week and find out a spray arm is clogged!
Do Other Monitoring Products Work?
WashChecks have been tested against other products where they had an 85% higher detection rate than other monitors. Read the full study online.
