I am amzed that an agency wuld not allow a bag in a home. Using this logic, you couldn't wear your coat or clothes in either as you are transferring infection. Our agency provides specific Home Health bags that are large square back packs. We use barriers whenever a doorknob is not close by. The bags have looped handles at the top specifically for hanging on doorknobs. Every item taken out from the bag is wiped with germicidal wipe prior to replacing it in the bag. We all take a class on "bag technique," and try to keep the inside of the bag "clean." We also take a class in wound dressing techniques to be used in the home. many of us have a second smaller bag from American Home Patient we use for simple "routine" visits.
