Had home care only twice, for limited time. Your doctor tells them why and what, here, and that's all they do, in cases such as mine. I was able to use bathroom by self, even shower with shower seat & grab bars. She would have come if I oouldn't shower by self. Walker, otherwise. Not sure if they could require you to put in grab bars, never thought to ask; we had them already.
I'd say: ask. You might ask Doc, too, to put it on order if you have enough problems doing it by self. My Doc went through the: Can you do this, can you that. Also, the: don't do this and that, or have your wife help.
Neither of mine had to stay at our house. One came only to change my port, if something went wrong with it. Or double check me once a week, take blood sample, bring me next round of antibiotics for self injection through port.
