I was thinking along the same line as catty1- would your stepdad qualify for visiting nurse services? With the right care, he might be better off to recover at home, away from people with things like viral illnesses and antibiotic-resistant infections. Did they remove the drains before he went home? Some of the newest antibiotics (like Cipro and levofloxacin) are just as effective when taken as a pill as they are when given intravenously.

Prayers for your stepdad and you! (((HUGS)))
