I think you need to become very assertive regarding your husband's care. Stop tolerating them leaving him filthy. You cannot get rid of an infection if filth is present. He has toxins and germs in his urine and stool, and having them all over him just makes him sicker. Go into the hospital, stay as long as it takes to get a real doctor, NOT an intern and maybe not even a resident. Having IVs and the PICC line means he has an open wound for germs/filth to use to get into his body, and not cleaning him means he gets sicker and more types of germs get into him. Stop accepting the situation, get a patient representative, give her a written list of the problems, let her know if it continues that you will seek advice from an attorney because this violates the most basic rules of care Make sure you take photos of how you find him even though they will break your heart.
Find the office for the top administrator of the hospital. GO and sit and wait to speak to them. Tell them the problems a nd that photos of a man left in filth with dirty wounds created by the doctors, as that is what the biopsy is, would make a great story for the media - and give him just a couple of days to fix the situation.
I know your time is scarce and this might mean a day off, but I think it needs to happen
Remember, document document document - every person you speak to, what they do, etc
