I worked in a clinic type setting and we also called out the patients name in the waiting area. And as a patient, they have always used names in any doctor's office I have been to. I am curious to know the same. Also, are sign in sheets a HIPPA violation? I have been to doctor's offices where you have to sign in your full name with the doctor you are seeing, and they don't cover up the previous names. Where I work now in a hospital, we have a visitors log with patients names in it.
