QUESTIONS WITH VERIFIED
CORRECT ANSWERS. A+ GRADE
RATED
1. 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 that results in an
interface message being created and sent
2. An interface message contains....: Data about an event (like a patient being
admitted to the hospital)
3. 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
4. Segment Identifier: Three character code that identifies what kind of data
that segment contains 5. PID-5: patient name
6. NTE segment: can follow many different segments
7. Z-segment: custom segment for a specific implementation
,8. Is it necessary to send empty fields following the last valued field?: No 9.
Within a field do you need to send all components?: Only as many as are
valued
10. Blank fields...: don't file anything
11. Delete character HL7: double quotes " "--- tells the receiving system to
delete a piece of info it has
12. FHIR: specifies RESTful exchange method via HTTPs to access data
13. Other standards supported by Bridges: X12, FHIR, NCPDP, DICOM, and
Direct
14. 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
15. Queue: storage location outside of Chronicles database structure
16. Event Queue is procesed by...: the Event Daemon
17. Daemon (Outgoing Message Flow): process that runs in the background
without any direct user action
18. 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
, 19. Data Queue (Outgoing Message Flow): contains the full text of the message
along with some additional metadata (i.e. timestamp) about message
processing 20. Control Queue (Outgoing Message Flow): a to-do list and
contains very little data
-processed by the Communications Daemon
-maintains a list of messages waiting to be processed
21. Comm Deamon (Outgoing Message Flow): reads an instruction from the
Control Queue and copies the appropriate message off the Data Queue
-sends the message out of Epic and waits for an ACK to be reutrned
-deletes instruction from the Control Queue and proceeds to the next instruction
-sends or receives acknowledgments over a TCP/IP connection
22. Comm Daemon (Incoming Message Flow): -listens constantly for
messages coming into the system
-validates MSH-11 and MSH-12 before accepting it, storing it in the data queue,
and adding instruction to the control queue
-sends or receives acknowledgments over a TCP/IP connection
23. Control Queue (Incoming Message Flow): processed by the Filer Daemon
24. Filer Daemon: pulls an instruction from the Control Queue, retrieves the
corresponding message from the Data Queue, and then attempts to file the
message.
Filing means that the Filer Daemon attempts to store the data in Chronicles.
