An overview of the integration between the application workflow and bridges, focusing on the processing of interface messages. It explains the role of the holding queue, control queue, and filer daemon in managing and processing these messages. The document also discusses the ability to resubmit and retrigger outgoing interface messages, as well as the various utilities available for message search, viewing, and editing. Additionally, it touches on best practices for conducting efficient message searches. The information presented in this document is likely relevant for university students studying topics related to healthcare information systems, enterprise application integration, and workflow management.

When is duplicate prevention performed? ----------- Correct Answer ---------- when an incoming interface that can create patients does not find the patient by ID and ID type What are the four possible outcomes of patient Identity Duplicate Checking and the recommended actions for those outcomes? ----------- Correct Answer ---------- 1) no match- create a new patient and file message 2)Low threshold matches- create a new patient and file messages
The filer Daemon checks messages on the Holding Queue periodically to determine whether messages on the Holding Queue are ready to file If the Filer Daemon encounters a message on the Control Queue that needs the same locks as a message already on the Holding Queue, that message is also added to the Holding Queue. This ensures that the messages always file into Chronicles in the same order they were received for a patient Holding QUeue ----------- Correct Answer ---------- Acts as a waiting area for messages that cannot get a lock to store information to the database Interconnect ----------- Correct Answer ---------- Epic's web services framework
What does it mean for an interface to process a message? ----------- Correct Answer ---------- the incoming interface's Filer Daemon tries to find the correct patient and file the data in the message into Chronicles the outgoing interface's Event Daemon creates an HL7 message, based on information in Chronicles, and sends it out through the port defined in the Comm Daemon. Are messages ever manually deleted from the Data Queue? ----------- Correct Answer ---------- No, never. They are purged only by an automated purge job. Communication Status (Interface Monitor Column) ----------- Correct Answer ---------- whether the comm daemon is stopped or running Total Recv'd/Sent (Interface Monitor Column) ----------- Correct Answer ---------- total number of messages sent (outgoing) or received (incoming) i.e. count Last Recv'd/Sent (Interface Monitor Column) ----------- Correct Answer ---------- Number of the Last message sent (outgoing) or received (incoming) i.e. message number Time since last message( Interface Monitor Column) ----------- Correct Answer ---------- Elapsed time since a message was last sent (for an outgoing interface) or received (for an incoming interface) Queued Messages (Interface Monitor Column) ----------- Correct Answer ---------- number of messages waiting to be sent (outgoing) or processed (incoming) Queued Events (Interface Monitor Column) ----------- Correct Answer ---------- number of events waiting to be processed from the Event Queue (outgoing only) Waiting Messages (Interface Monitor Column) ----------- Correct Answer ---------- Number of messages waiting to be processed from the Holding Queue Filer/Event Status (Interface Monitor Column) ----------- Correct Answer ---------- Whether the Event Daemon (outgoing) or Filer Daemon (incoming) is stopped or running Background Monitor ----------- Correct Answer ---------- takes care of many tasks including determining whether interfaces are running Interface Monitor Definition ----------- Correct Answer ---------- Allows you to specify which interfaces should be displayed in the Interface Monitor activity Interface Monitor ----------- Correct Answer ---------- displays the interfaces from the definition. There are several pieces of information available about each interface displayed:
Path: Epic>Admin>Interface Admin>Background Monitor Definition> Autostart Epic App for monitoring interfaces on mobile device ----------- Correct Answer ---------- Haiku With Haiku, you can access what details about an interface? ----------- Correct Answer ---------- - ID and name
Message Search ----------- Correct Answer ---------- allows you to specify an interface, a string to look for, and a time period. The activity then returns all messages that match that criteria
period searched
"Fix" errors ----------- Correct Answer ---------- problems that can be eliminated by a change to the system to permanently elimnate the problem "Suppress" errors ----------- Correct Answer ---------- some errors are benign and require no further action, so those you can simply suppress "Work" errors ----------- Correct Answer ---------- errors you expect to happen periodically and will require manual intervention as part of the ongoing maintenance of the interface Possible steps one might take to resolve a "Fix" or "Work" error ----------- Correct Answer ---------- - correct a data mapping issue within Epic
interfaces, system-wide profile variables, and system-wide error handling INTF_USER profile variable ----------- Correct Answer ---------- it is the user associated with the interface audit trail entries if no user is present in the message interface will not start without this pv added What must be done once you have made changes to a custom override to ensure the changes will take effect? ----------- Correct Answer ---------- Compile the custom override and restart the interface Profile variable usage report ----------- Correct Answer ---------- compares settings of profile variables across interfaces Profile variable audit report ----------- Correct Answer ---------- tracks the changes to a profile variable within a specific interface If you change a profile variable in one interface specification, does it affect the profile variable in other interfaces? ----------- Correct Answer ---------- No, just the one interface specification in which the change was made Editing the system definitions profile variables requires that you...... ----------- Correct Answer ---------- stop all interfaces that are listed in the Background Monitor Inherited profile variables ----------- Correct Answer ---------- profile variables that are in use by an interface that are defined in the system definitions one of the easiest types of custom overrides ----------- Correct Answer ---------- skipping a field T/F: A single custom override can be used across multiple interfaces of the same type ----------- Correct Answer ---------- T A custom override is created from... ----------- Correct Answer ---------- within the interface specification
for incoming interfaces, this is where you configure what you expect to receive in MSH-11 and MSH-12, which control whether a message will be acknowledged by the comm daemon If you need to dynamically populate some message header fields on an outgoing interface... ----------- Correct Answer ---------- there are profile variables that can override the values specified in the HL Header tab Epic's Enterprise Master Patient Index ----------- Correct Answer ---------- Identity Enterprise Master Patient Index ----------- Correct Answer ---------- lets you correctly identify records in a setting where each record may have more than one type of ID
