My mother lives by herself in small Kansas town with limited resources about 4 hours from me. For years she has had the assistance of a case worker (weekly or bi-weekly) in managing mental health, basic finances, and medicare/health insurance/prescription plans. I have power of attorney to assist and am not sure where to begin finding a new case worker and/or transportation assistance to help her get to appointments (she drives, but not on Interstates or highways). I can make the trip to her occasionally, but she benefits from having a local caregiver/assistant. Any suggestions?
You can look up Geriatric Care Managers and they can do what you are describing.
But when I hear the term "Case Manager" I am thinking this is through some funded program. If that is the case then the Case manager has a supervisor that you could be able to talk to.
You could also try contacting your Area Agency on Aging.
In many areas Catholic Charities runs programs (this is not just a Catholic organization they help all)
Some Senior Centers have Social Workers that are aware of programs in the area.
