My father is 88 and is in a wheelchair. My mother is 84 and has issues of her own. Both live in Monroeville Alabama. He has been receiving home health twice per week for bathing. That has been cut down to one day a week Wednesday). I don't know when home health will discontinue this service altogether. We need to find someone to come to their home and bath him, preferably three days a week (Monday, Wednesday and Friday) that is reputable and cost-effective. My mother simply does not need to do it. Otherwise, she is going to need hip surgery or other.
Your dad's Dr. can write a referral for a bath aide who will come to the house to bathe and groom your dad. Their office will set it up.
