M NET: a statewide referring physician computer network.

M NET, the Referring Physician Computer Network, is a joint project between the University of Michigan Medical Center (UMMC) and IBM. A graphical user interface was developed to allow referring physicians easy access to a variety of patient, clinical, and institutional data. File transfer mechanisms were created and current clinical database files and programs were enhanced and restructured to facilitate remote data transmission. M NET is currently installed in referring physician office sites across the state, with additional physician sites identified and program enhancements under development.
