EDI101 - BRIDGES INTERFACES QUESTIONS AND
VERIFIED ANSWERS
No, the encoding characters can be any printable character. - Answers - Does every
HL7 message have to be encoded with the characters |^~\& ?
The result is positive \T\ has a value of 2.7 x 10\S\3. - Answers - Imagine that your
message begins with MSH|^~\&|. How would you encode the string "The result is
positive & has a value of 2.7 x 10^3."?
Context; its meaning depends on the segment it follows. - Answers - Why is the NTE
segment special?
An empty field is ignored by the interface, whereas the delete character will delete
information from the database, assuming the field in question supports the delete
character. - Answers - What is the difference between receiving an empty field || and the
delete sequence |""|?
X12, FHIR, NCPDP, DICOM, and Direct. - Answers - Aside from HL7 Version 2, name
two other standards supported in Bridges?
Epic's interfacing application. It consists of both the interface infrastructure to build,
send, receive, and file messages along with the tools and utilities to maintain those
interfaces. - Answers - What is Bridges?
The Event Queue contains the information needed to build a message. Usually this is a
patient ID, an encounter DAT, and the type of message to be built, amongst other
information.
The Data Queue contains the text of HL7 messages and additional metadata.
The Control Queue is a to-do list of message numbers to send or file. - Answers - What
are stored in the Event Queue, Data Queue, and Control Queue?
No, never. They are purged only by an automated purge job. - Answers - Are messages
ever manually deleted from the Data Queue?
TCP/IP with an interface engine is the most common communication method.
Interconnect is used for HTTPS or other communication outside your local network. -
Answers - What are two ways that interface messages are sent and received?
- Answers - Describe the flow of messages in and out of Bridges for an interface using
a TCP/IP connection.

  • Answers - Describe the flow of messages in and out of Bridges for an interface using a TCP/IP connection.
  • Answers - Describe the flow of messages in and out of Bridges for an interface using Interconnect. Yes. You can start any or all of the interfaces in a given interface monitor. - Answers - Can you start more than one interface at a time with the interface monitor? Make sure that interface is first listed in the Background Monitor. - Answers - What do you have to do before you can add an interface to an interface monitor definition? Interface ID and Is Interface On Monitor properties - Answers - Which properties can be used to specify the specific interfaces evaluated by an alert rule? False. The session history only shows the actions taken by the logged-in user during the current session. - Answers - True or False: The Session History shows all interface start/stop requests by all users in the system. You can see errors associated with that message and message submission details such as the timestamps when the message was added to the data queue and processed. - Answers - In the Message Viewer, what information is available besides the text of the message? You can edit an entire segment at once or edit each field individually. - Answers - Can you edit an entire segment at once or must you edit each field in that segment individually? No. The Message Editor is a free text editor. It has no idea how the message should look. - Answers - Does the Message Editor perform validation to ensure that the value entered is appropriate?
  • Limit the time period searched
  • Search for unique identifiers (MRN, CSN, order ID) as opposed to patient name
  • Include multiple search values in your search criteria - Answers - If you are running a message search, what best practices could you use to reduce the amount of messages returned by your search or finish your search quicker? No. You can never manually delete a message with any Bridges utility. This utility removes the entry only from the Control Queue. - Answers - Are you deleting a message from the Data Queue with the Skip Message action? There are several ways to accomplish this:
  • Use the Filters option from the Message Search toolbar to limit your search results by Patient Name to only DOE, JONATHAN.
  • Re-run your search and change the criteria of the search to: PID-5.1 Equal to "DOE" AND PID-5.2 Equal to "JONATHAN"
  • Find the patient's MRN so you have a unique identifier and re-run your search and change the criteria of the search to: PID-3.1 Equal to - Answers - You ran

Compile the custom override and restart the interface. - Answers - What must be done once you have made changes to a custom override to ensure the changes will take effect? The triggers for outgoing interfaces, system-wide profile variables, and system-wide error handling. - Answers - What is contained in System Definitions? ID; ID Type - Answers - To identify a patient using Identity you need the _____________ and the _____________. No, you can have the same Identity ID for different records in the same master file as long as they are tied to different Identity ID types. - Answers - Must an Identity ID be unique across the entire system? result statuses - translation table procedures - Identity departments - Identity patient classes - translation table patients - Identity US states - translation table transcription types - translation table allergies - Identity - Answers - For the following list of concepts, determine which would use Identity and which would use a translation table for their mapping: result statuses, procedures, departments, patient classes, patients, US states, transcription types, allergies No. An ID Type can be defaulted, or a programming point can be used to find an ID Type. - Answers - Must you receive an ID type over the interface to find a record in Epic? Yes, a table that translates in a single direction (that is, incoming or outgoing, but not both) can use a many-to-one mapping. - Answers - Can a translation table support a many-to-one mapping? Auto lookup leverages the category list build in Epic (typically either the title or abbreviation) to establish the mapping between the external value and Epic's internal value. The most common use case for this would be for US states where the abbreviation (i.e. postal code) is universally agreed upon. - Answers - Describe the auto lookup option available for translation tables and a good example of when you might use it. When an incoming interface that can create patients does not find the patient by ID and ID type, duplicate prevention is performed before creating a patient record to ensure that the patient doesn't already have a record in the database. - Answers - When is duplicate prevention performed?

  1. No Match - Create a new patient if the interface can do so, and file the message
  2. Low Threshold Match(es) - Create a new patient if the interface can do so, and file the message
  3. Single High Threshold Match - File message to existing patient
  4. Multiple High Threshold Matches - Log a fatal error - Answers - List the four possible outcomes of patient duplicate checking and the recommended result of each? When any patient-based incoming interface finds the patient record by ID and ID type, patient validation is performed to confirm the interface has the correct patient record before filing any data. - Answers - When is patient validation performed? Basic Validation, Extended Validation, Identity Duplicate Configuration (IDC) - Answers
  • What are the three types of patient validation an interface can use? High Threshold - Answers - Which Identity Duplicate Configuration threshold is used for patient validation?
    • Answers - Diagram the process for duplicate prevention.
    • Answers - Diagram the process for patient validation. Data Courier (for tables and workqueues), Pack/Unpack records (for new interface objects), and manual migration (for changes to existing objects). - Answers - What are the three methods for data migration of interface objects, and when is each one used? Sherlock - Answers - What online tool can you use to document details about issues you encounter? False. Interface specifications must be migrated using the pack/unpack utility. Content management tickets can migrate all data-courier enabled records that are linked to an interface. - Answers - True or False: Content Management tickets can be used to migrate an interface specification
