To me the key word in here is interval. If a regularly scheduled interval is set, this could be daily , weekly, monthly or quarterly. Obviously there are going to be the times when a contaminant is there and the machine has to be brought down, but also I do not see the mention of the UV light. We have a Leica that has an internal UV button. This is pressed everyday as well as normal daily maintenance. Once a month our cryostat is brought down for decontamination. This is part of the normal maintenance. I agree that is the CAP wants this to happen, it needs to be clearly defined within the question and not up to interpretation.

I am not sure how we get to CAP on this however; it makes no sense for a really busy lab unless they want to give us enough cryostats to make up for the problem this will cause. Is this something NSH might decide to help with? It may be time to bombard them (CAP) with questions and report the issues it will cause with patient care. None of us want to use a contaminated cryostat but we also know how to decontaminate without being in danger and stopping surgery for frozens .

No references are given documenting or supporting the need for this onerous and cumbersome weekly requirement. I suggest we lobby the CAP and demand both documentation supporting the need for weekly defrosting or, better, a more user friendly and sensible standard. Jeff Silverman **REVISED** 06/15/2009 ANP .12087 Phase II N/A YES NO Is there a documented procedure for the routine decontamination of the cryostat at defined intervals, and are decontamination records evident? NOTE: The cryostat must be defrosted and decontaminated with a tuberculocidal disinfectant at an interval appropriate for the institution; this must be weekly for instruments used daily. Trimmings and sections of tissue that accumulate inside the cryostat must be removed during decontamination. Although not a requirement, steel mesh gloves should be worn when changing knife blades. --------------------------------------------------------------------------------- The information contained in this electronic e-mail transmission and any attachments are intended only for the use of the individual or entity to whom or to which it is addressed, and may contain information that is privileged, confidential and exempt from disclosure under applicable law.
