We have nightly checks that we do, and a paper record of it (checking glucometer, frig temps, etc).
How long should these records be kept?
DNV is our hospital accrediation provider.
I would think your facility would have a policy regarding records disposition. If anyone would know I'd think it would be your legal department.
3 years. That's the time frame that TJC operates on
ETA: Sorry, didn't see your comment about DNV. I know nothing about that. But I would assume that it would be similar. If TJC requires a certain time period, it's because CMS does.
