Incoming interfaces must identify the correct ID Type to successfully locate a record in Chronicles. They do this in two primary ways:

Default ID Type: The interface can be configured with a fallback ID type to use if no other information is provided.

External System Settings: The interface can look at identifiers within the HL7 message (like the Assigning Authority in PID-3.4) and match them against the " External System Settings " defined in the ID Type configuration . Option C is incorrect because searching without a defined ID type would be inefficient and could lead to incorrect record matches.

If an incoming message arrives for a patient whose record is currently being edited by a user in Hyperspace, the record is " locked. " Bridges cannot file to a locked record, so it places the message in the Holding Queue . Once the user finishes their work and the lock is released, the message is moved back to the Data Queue to be filed.

Bridges supports searching through XML-formatted messages by navigating the message structure. Analysts can use an absolute path (defining the exact location from the root element) or a relative path (searching for an element regardless of where it resides in the hierarchy) to find specific data points within the XML payload. Searching by communication method (Interconnect) identifies how a message traveled, but does not search the content of the XML itself.

HL7 provides a standard set of segments (like PID for Patient Identity or MSH for Message Header). However, to allow for site-specific data that doesn ' t fit into standard segments, HL7 reserves the letter " Z " for custom segments. Any segment starting with " Z " (e.g., ZPV, ZCD) is considered a local, non-standard extension defined by the specific healthcare organization or vendor.
