We used a care manager for the last two years that my mom was able to live independently. I lived 4 hours from my mom and my brother was an hour away, so we needed someone local to check in on her regularly and provide assistance. They were a great help with picking up medications, stocking the pill dispenser, giving rides to appointments, communicating with the management of my mom's senior apartment building, and just general support. They were our eyes and ears and reported their observations to us regularly. The Aging Life Care Association's website is a good source of information for what care managers do and how to find an accredited one in your area.

It's certainly not cheap - our care manager charged $150 per hour. The peace of mind was worth it to us. Our care manager was also a big help in planning for my mom's eventual move from independent living to our house in Virginia, and then to assisted living/memory care, where she is now.
