EDI101 Sample Questions Answers

When an interface uses Interconnect (Epic ' s HTTPS-based framework) for incoming data, Interconnect receives the message directly via a web service call. Because it is an HTTPS connection rather than a standard TCP/IP socket, Interconnect handles the initial receipt and places the message directly onto the Bridges Data Queue for the Filer Daemon to process.

The " Review Required " status acts as a safety hard-stop in Bridges. This status usually appears after a system upgrade or when a new interface is created from a template. Bridges prevents the daemons from starting as long as a variable is marked for review to ensure that an analyst has verified that the settings are appropriate for the specific environment, preventing potential data filing errors.

If workqueue rules are updated or if errors need to be reassessed against existing rules, the Interface Error Workqueue Maintenance activity is used. This utility allows the system to sweep through existing errors and re-apply logic to ensure they are appearing in (or have been removed from) the correct workqueues.

When you edit a message within the Bridges Messages activity, you are not overwriting the original message on the data queue. Instead, Bridges typically creates a new version of the message for resubmission or processing, preserving the original message ' s history and integrity for auditing purposes. The original data remains intact as part of the interface ' s message log.

In HL7 v2 messaging, a standard naming convention is used to identify specific data locations. The format follows Segment-Field.Component.Subcomponent. For example, PID-5 represents the Patient Name field. To specify a component within that field (like the Given Name, which is the 2nd component), a dot is used as a separator. Therefore, PID-5.2 correctly identifies the 2nd component of the 5th field.

The Error Code is a unique identifier assigned to a specific type of failure (e.g., " Patient Not Found " ). Because every instance of that specific failure across multiple messages will share the same code, it serves as the primary property for grouping errors to identify systemic issues or root causes.

Similar to profile variables, purge settings follow a hierarchy where the more specific configuration overrides the more general one. Because the Interface Specification is more specific than the System Definitions, its value of 45 days takes precedence. Messages for interfaces using that specification will be eligible for purging after 45 days.

The Interface System Defaults activity is the highest level of the configuration hierarchy. Settings defined here serve as the global " catch-all. " If a profile variable is defined in System Defaults and not overridden at the Specification or individual Interface level, that single setting applies across the entire Epic environment for all relevant interfaces.

The Criteria tab allows for precise filtering of logs. Analysts can search for errors associated with a specific message (Option B), filter for specific error codes to investigate a known issue (Option C), or isolate critical issues by filtering for a severity of " Failure " (Option D). Severity overrides (Option A) are a configuration setting rather than a standard search filter for the log report itself.

The Message Companion relies on a successful link between a message and a specific record (like a Patient or Encounter). If a message encounters a failure error during processing (e.g., a critical identification error), Bridges may be unable to definitively link that message to the patient record in Chronicles. Because the link is missing, the message will not appear in tools like the Message Companion that filter specifically by that patient ' s ID.

Bridges provides a configuration toggle for Case Sensitivity within translation tables. This is crucial because some external systems might send values like " M " and " m " interchangeably, while others might use case to distinguish between two different codes. Setting this correctly ensures that the interface accurately matches the incoming string to the intended internal value.

The Message Search activity in Bridges is designed for flexibility. One of its core features is the ability to select multiple interface specifications or even all interfaces within a search. This allows an analyst to track a patient’s data across different systems (e.g., searching for both Lab and Pharmacy messages simultaneously) in a single consolidated result list.
