New York Times ran a great article on how an integrated healthcare system in Alaska was able to dramatically reduce cost and improve outcome by building a system that incentivizes everyone to work together as teams. One of the key enablers of such collaboration is an integrated Health IT system that they call "data mall". It is not your typical patient record system, but rather an analytics driven quality measurement system. To quote from the article:
Integrating a wide range of data to measure medical and financial performance. Southcentral’s “data mall” coughs up easily understood graphics showing how well doctors and the teams they lead are doing to improve health outcomes and cut costs compared with their colleagues, their past performance and national benchmarks, and it provides them with action lists of what they can do to improve and mentors to guide them. That almost always spurs the laggards. One doctor whose team ranked well behind 10 others in scheduling annual eye exams for diabetics jumped to first place within two months once she became aware of how poorly her team was performing.
