title: Dueling platforms [healthcare network servers]
abstract: Many large hospitals and healthcare systems have grown accustomed to the reliability of mainframe architecture, although tighter operating budgets, coupled with advances in client/server technology, have led to more office and clinical applications being moved off mainframes. But Evanston Northwestern Healthcare wasn't ready to get rid of its IBM OS 390 mainframe just yet. While a number of new clinical applications are being installed on two brand new IBM servers, Evanston Northwestern Healthcare will retain its favored hospital billing system and let it reside on the organization's mainframe, as it has since 1982
