PE I totally sympathize. My mother runs a home healthcare facility - she employs and directs the nurses who visit patients in their own homes. About 85% of their patients are elderly folk like your mother. Their care can range anywhere from a couple visits a day, to once a week, once a month, etc. It's very customizable and they typically work directly with a caregiver if needed - someone usually hired help to keep the patient company and help with daily tasks like making meals and showering and driving to and from dr. apts - this is also customizable. They can't administer medications or change post-op dressings so that's when my mom's nurses step in.The only thing she wants is to be back in her house on her own again. The rehab center tells me this will never be able to happen, of course she disagrees.
And because my mom does what she does, she's also been a couple family members' advocate/healthcare proxy. She's been in your place a few times for family too, most recently for a very close aunt. She was incedibly stubborn with dementia and lived in the middle of nowhere. Even though my mom was proxy, she felt pressured by her own mother and her other aunts to let this aunt live out her days at home, however she would have benefited greatly from going to an assisted living facility. As much as the sisters didn't want to move her, they also didn't want to help with the work and my mom ended up being her nurse, on top of her full time job running these types of nurses, and really wore herself out trying to help our aunt. It was frustrating to listen how even though this was her JOB and she was an expert on elderly care, noone would listen when she insisted it was time to move my aunt to a home. And of course whenever my aunt was lucid enough, moving would never have been an option to her.
It's frustrating. However I suggest starting with nurses and caregivers that can come visit your mother at home - and make sure you keep strong lines of communication with them.
edit to add: these kinds of places work directly with insurance. This is not ALL out of pocket.
