Palliative care implies something like Hospice, end of life care. I think you might be asking for what additional services they will need while they are aging but not at the very end and need help dying.
It sounds like they need more help, more than a few times a week, rather daily. Maid service, meal service (assuming dinner is provided by the facility) help getting dressed, ready for bed, help with bathing.
If you or they have the money to pay for it, I would find care providers (Visiting Angels is one) and put a plan together with them.
