"Home care services range from medical care to help with daily household chores. If you're considering home care services, ask these questions to choose the best provider for your needs." Mayo Clinic Healthy Aging Newsletter.Mayo Clinic has a great article with suggestions for how to select home care services, what types of services are available, and what to monitor.
Essentially, they say to make sure agency is licensed, find out how the person providing the care is monitored by the agency, and what to monitor yourself. It seems ironic to me that home care is less expensive and in many respects more desirable than placement in an assisted living situation, but our long term care insurance will pay significantly less for those services. hmmmmm. Seems counterproductive to what might be the best options.
At any rate, if you are considering in-home services, this is a good article to read.
