Trigger - Serves as the integration point between the application workflow and Bridges generally, an action in Hyperspace, like clicking a button or closing an activity -a single, clearly defined action that a user or process can take those results in an interface message being created and sent An interface message contains.... - Data about an event (like a patient being admitted to the hospital) MSH-11 and MSH-12 are... - the HL7 processing ID and version; Epic checks these values on an incoming message and rejects the message if they do not match the expected values Segment Identifier - Three character code that identifies what kind of data that segment contains PID-5 - patient name NTE segment - can follow many different segments Z-segment - custom segment for a specific implementation Is it necessary to send empty fields following the last valued field? - No Within a field do you need to send all components? - Only as many as are valued Blank fields... - don't file anything Delete character HL7 - double quotes " "--- tells the receiving system to delete a piece of info it has FHIR - specifies RESTful exchange method via HTTPs to access data Other standards supported by Bridges - X12, FHIR, NCPDP, DICOM, and Direct Event (in context of outgoing message flow) - small set of values with the necessary info to build the message: patient ID, patient contact, type of message, and additional info -contains directions for where the interface should pull the information it needs from the database Queue - storage location outside of Chronicles database structure Event Queue is processed by... - the Event Daemon Daemon (Outgoing Message Flow) - process that runs in the background without any direct user action Event Daemon (Outgoing Message Flow) - pulls an event off the Event Queue, uses the information in the event to build the message and finally deletes the event from the event queue. The event daemon puts the message it has built onto the data queue and adds an instruction to the Control Queue builds an HL7 message based on data pulled from Chronicles Data Queue (Outgoing Message Flow) - contains the full text of the message along with some additional metadata (i.e. timestamp) about message processing
