Real Time Information Director User Documentation

These enrichments come into play when a patient’s chart needs to be updated as the result
of a medical encounter. Here is an excerpt from the UpdateEncounter document
definition. This document definition refers to several of the enriched records defined in
EHR.java:
public class UpdateEncounter extends NativeDocumentDefinition
{
private static DocumentRecord documentRecord =
new DocumentRecord(EHR.lookupEncounterRecord,
new RelatedRecords(EHR.externalChartEntryRecord, new
RelatedRecords[] {
new RelatedRecords(EHR.observationRecord),
new RelatedRecords(EHR.externalTestsRecord),
new
RelatedRecords(EHR.externalMedicationRecord),
new
RelatedRecords(EHR.externalImmunisationRecord),
new RelatedRecords(EHR.externalReportsRecord),
new RelatedRecords(EHR.externalReferralRecord)
}));
…
public UpdateEncounter()
throws DirectorException
{
super(documentRecord, "UPDATEENCOUNTER", "UPSERT");
}
}
When an UpdateEncounter document arrives, the Director fetches and stores the internal
IDs for the provider and the organization in various tables. When a query arrives for the
same information, the Director fetches and delivers the external IDs used within the
application.
Procedure to Create a QualifiedMapping Enrichment
Sometimes it is convenient to use a single mapping table can be used to store various
categories of lookup values. For instance, the EHR example contains a type codes table
that contains various valid abbreviations along with the complete descriptions. The
TYPECODE column identifies the category of abbreviation, such as "TESTTYPE" or
"IMMUNISATION".
In a case where the same lookup table performs double or triple duty, the metadata must
do more than correlate external and internal IDs: it must also specify the category of the
lookup, for example whether to look up the ID for a test or an immunization. (In this
scheme, a test and an immunization could have the same ID.) The category indicates
which records in the lookup table to consider.
The procedure to create this kind of mapping consists of three steps instead of two.
