In the next phase of a $600 million investment, Novant Health will flip the switch this weekend on an electronic medical record system at its Triad hospitals. The new system made by Wisconsin-based Epic, dubbed Dimensions by Novant Health, will begin being used at Novant's Forsyth Medical Center, Kernersville Medical Center, Clemmons Medical Center, Medical Park Hospital and associated outpatient and surgery centers Saturday morning. Emphasis shifted to Novant's hospitals following its implementation of the new system in more than 300 physician offices last year, a process that Novant officials said was completed ahead of time and under budget.
