Feldman says he believes that the cost savings found in his study could be replicated at other hospitals.
"If I were a CEO that had a provider order entry system that allowed me to easily show these costs I would certainly start showing the cost of a lot of our relatively inexpensive but frequently ordered tests. You are better off if you are reminded of it right when you need it. That was part of the power," he says.
"There are lots of studies out there where people have gone on with big educational efforts and the problem is they require a lot of effort from the faculty and they are quickly forgotten if they're not brought up on a regular basis," he says. "The beauty of ours was that it was a very cost-effective way of providing this information on a continual basis."
At the same time, Feldman says physicians do not need to be aware of the cost of every test or professional service they provide.
"I am worried about people getting cost overload," he says. "But for the tests that I know that my docs are ordering every day and maybe on a repeat basis… if I had the opportunity that would be where I would try to make the biggest impact."
