The highly respected and world renown Mayo Clinic is a supporter of home health care services. They recently posted a page on their web site offering advice to consumers on how to choose the best provider of home care services.
Here's a link to the site: May Clinic Home Care
One thing you may want to consider is posting a link to this site on your web site. Linking back to Mayo Clinic gives your patients and referral sources an objective source of information.
You can also use this in your home care sales efforts. Have your sales representatives encourage referral sources to visit the Mayo Clinic site.
All of this presumes that your agency is the one that patients or referral sources would choose after following the Mayo Clinic's advice.
