Abstract: A system supporting perioperative workflow includes a backend system with at least one database; at least one application configured with the database(s); and at least one user interface (UI) mechanism supporting a plurality of role-specific graphical user interfaces (GUIs) to the backend system. The backend system maintains an authoritative version of perioperative workflow information for each of a plurality of patients. One or more devices are configured with at least some of the role-specific GUIs, and operably connected to and interact with the backend system via the UI mechanism(s). Each device is configured to: receive and display perioperative workflow information from the backend system in a role-specific GUI on the device; and to send perioperative workflow information to the backend system via the role-specific GUI on the device.
