My MIL is living with us after a failed attempt in memory care due to their lack of compassion and care. Does Medicare pay or help in anyway for skilled nursing to come in to give me any kind of break. She literally needs eyes on her 24/7. She is wheel chair or bed bound but is unaware she can not walk. This makes her a huge fall risk. Also she has Sundowners and we are all sleepless. We already have a great Hospice team for bathing and such 3 days a week.
You may need to hire help out of pocket from an agency. Medicare does not pay for any other services other than those offered by Hospice at the juncture you are at.
I think you would be better off looking for another facility and applying for Medicaid.
You say she needs 24/7 eyes on her, that isn't going to happen anywhere. Having her at home allows you to restrain her so she is not trying to walk. Tying her in the wheelchair and using bed rails can keep her from falling. Medication to help with the sundowning is also useful. Talk with her hospice provider about meds that can calm her down and allow her to sleep. Keep her awake during the day, anyway you can and find things that tire her out. Those may help her and you.
Talk with hospice and find out if they have volunteer sitters so you can have a break during the day. Ask them if they know anyone that does overnight sitting and use her social security check to pay for as many nights as she can afford, because every little bit helps.
