SYSTOC HL7 Exchange Communication Requirements

Implementation of the SYSTOC HL7 Exchange modules requires the participation and commitment of three groups: Workplace Health & Safety (WHS), the WHS customer, and the staff from the third-party system (laboratories, radiology facilities, or hospital information systems). Customers provide project leadership and resources that work with WHS engineering staff and third-party system staff to maintain progress and see the project to completion. WHS staff can only implement these interfaces with committed customer and third-party resources.
