My favorite EMR consultant, Laura Jantos (from ECG in Seattle)—who retains that title despite owing me lunch since 1995—has a report out from the California Health Care Foundation about tools for managing disease management systems. The very short  summary is that souped up DM registries are pretty good value for money compared to EMRs. This is deep in the weeds stuff, but if you care about chronic care programs, you should read it.
