EPIC BRIDGES EXAM QUESTIONS AND ANSWERS 2026/2027
Trigger -ANSWER-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
An interface message contains.... -ANSWER-Data about an event (like a patient being
admitted to the hospital)
MSH-11 and MSH-12 are... -ANSWER-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 -ANSWER-Three character code that identifies what kind of data that
segment contains
PID-5 -ANSWER-patient name
NTE segment -ANSWER-can follow many different segments
Z-segment -ANSWER-custom segment for a specific implementation
Is it necessary to send empty fields following the last valued field? -ANSWER-No
Within a field do you need to send all components? -ANSWER-Only as many as are valued
,Blank fields... -ANSWER-don't file anything
Delete character HL7 -ANSWER-double quotes " "--- tells the receiving system to delete a
piece of info it has
FHIR -ANSWER-specifies RESTful exchange method via HTTPs to access data
Other standards supported by Bridges -ANSWER-X12, FHIR, NCPDP, DICOM, and Direct
Event (in context of outgoing message flow) -ANSWER-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 -ANSWER-storage location outside of Chronicles database structure
Event Queue is procesed by... -ANSWER-the Event Daemon
Daemon (Outgoing Message Flow) -ANSWER-process that runs in the background without
any direct user action
Event Daemon (Outgoing Message Flow) -ANSWER-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) -ANSWER-contains the full text of the message along
with some additional metadata (i.e. timestamp) about message processing
Control Queue (Outgoing Message Flow) -ANSWER-a to-do list and contains very little data
-processed by the Communications Daemon
-maintains a list of messages waiting to be processed
Comm Deamon (Outgoing Message Flow) -ANSWER-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
Comm Daemon (Incoming Message Flow) -ANSWER--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
Control Queue (Incoming Message Flow) -ANSWER-processed by the Filer Daemon
Filer Daemon -ANSWER-pulls an instruction from the Control Queue, retrieves the
corresponding message from the Data Queue, and then attempts to file the message.
