St. Charles Health System says it will hire roughly 100 permanent “Epic analysts” as it heads into the massive process of switching its electronic patient records system, an undertaking that will take years and cost several million dollars. St. Charles announced last week it plans to switch from Paragon, its current electronic health records vendor, to Epic, one of the most widely used EHR vendors nationwide. The new positions will be filled largely by people who already work for the organization and understand its operations, but hires could come from outside as well.
