I'm not sure exactly what you are asking. In facilities where I have worked, it is the CNA's resposibility to be sure the TED's are put on in the AM and taken off at night. If this isn't being done, it is the nurses resposibility to follow up. Often it is just a matter of adding it to the Plan of Care or worksheet so the CNA is aware this resident is supposed to be wearing them.
Yes, it can be a problem!
Yes it is a big problem and we were cited for ted hose not on when they should be. I have a habit of checking those who have the order for them, as they come into the dining room and if they don't the cna/stna can turn them around to their rooms to apply them. We also have the problem of aides applying the tedhose and taking off the bandages completly and I catch it when i see blood seeping out of the nice new white hose I just got in. It has gotten better but it is a never ending job.
