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