This was in a short sidebar in this month's Nursing 2006. I didn't see this posted elsewhere here yet, so if it's a duplicate, I apologize. Since it's in a print magazine I can't provide a link.
It appears the hospitals and LTCs can now hire "mystery patients" who report on the treatment they receive.
According to the article, "...mystery patients pursue care up until an invasive procedure is recommended and report on both positive and negative aspects of the experience."
The companies cited as providing this service is called Devon Hill Associated of LaJolla, CA and Examine Your Practice in Las Vegas.
Incredible. Talk about a waste of resources.
Added: I found a link that was the source for the article. It's from NurseZone.com:
