Why Don't We Have Catholic Health Care Co-ops?

I am intrigued by this idea. I have learned much about the faith converted to many years ago. However I still don't get what is the purpose of a modern day Catholic hospital. What are they doing that let's say another secular hospital is not? (Except for the Crucifix in the Room and Elevators and a nice Picture of the Pope in the Lobby- THANKS!!!)

Among Catholics these questions have been strangely not talked about in this Health care debate.
