Very interesting to have the other perspectives, thanks!
Janfrn, just to be clear, I do understand how zero'ing works
Our problem is that often the nurse zero'ing the empty bed forgets to list what it was zero'd with, so then as the days pass and more and more stuff winds up on the bed, there is no way to know how to clear the bed to get an accurate wt. Was there one pad or two? a flat sheet and a blanket, or just a sheet? and so on... Then you have to get the pt onto the sling scale just because no one bothered to write down how the bed was zero'd, we don't have a policy in place that says always zero with xyx, or something like that.
I just feel like its an out of date policy that causes major upset and headache to the families/pts/nursing for no reason. You all have confirmed my "hunch", now I just need to hunt down some research on the subject if there is any.
