DH in hospital again

Just can't catch a break. DH has been admitted to the hospital today, again, due to having cellulitis. Third time in less than 6 months that he has had an infection that required IV antibiotics. The last time they sent him home after less than 12 hours. Tomorrow a geriatric care manager is doing an emergency assessment on him at the hospital. I need a better plan than me doing this alone. I cannot get him to shower or change clothing on a regular basis. I have read all the books and articles and have tried the techniques and he won't budge. This is exhausting.
