Note - Each ADT message containing a PV1 segment (i.e. Structure A messages) results in a new FHIR Encounter resource being created.
The newly created FHIR Encounter is linked to an EpisodeOfCare resource based on the PV1’s Visit Number (this is carried in the Attendance Number field).


== Segment - PV1 - Patient Visit ==
If the PV1 Visit Number is new – i.e. has not previously been seen by Discovery – this causes a new EpisodeOfCare resource to be created.
{| class="wikitable"

If the PV1 Attendance Number has previously been seen by Discovery, then the Encounter is linked to the existing EpisodeOfCare.

To see the latest Compass V2 schema, please see Discovery Remote Subscriber Database Familiarisation#Data_Mapping

The Discovery Data Service (DDS) takes HL7 ADT messages from a number of suppliers, transforms the data into FHIR, and makes this available for subscriber use. This page provides an overview the HL7 ADT message types, structure, transform process, and the ADT -> FHIR -> Compass2 mappings.

Further segment level details are described in the article Publisher API HL7 Messages where details of cardinality are also given

Message Structures

The messages types are grouped by their structure for transformation to FHIR, since this avoids a large amount of code repetition.

When saving FHIR to the Discovery store there are variations in handling of message types within the message structure groups.

The structures are as follows:

Structure A – Patient level messages

Applies to Standard segments Cerner custom segments
  • ADT^A01 (Admit/visit notification)
  • ADT^A02 (Transfer a patient)
  • ADT^A03 (Discharge/end visit)
  • ADT^A04 (Register a patient)
  • ADT^A05 (Pre-admit a patient)
  • ADT^A06 (Change an outpatient to an inpatient)
  • ADT^A07 (Change an inpatient to an outpatient)
  • ADT^A08 (Update patient information)
  • ADT^A11 (Cancel admit/visit notification)
  • ADT^A12 (Cancel transfer)
  • ADT^A13 (Cancel discharge/end visit)
  • ADT^A14 (Pending admit)
  • ADT^A23 (Delete a patient record)
  • MSH [1..1] Message header
  • EVN [1..1]  Event information
  • PID [1..1] Patient information
  • PD1 [0..1] Additional demographics
  • NK1 [0..*] Next of kin / associated parties
  • PV1 [1..1] Patient visit information
  • PV2 [0..1] Patient visit additional
  • OBX [0..*] Obs (used by Homerton for misc. admin data)
  • AL1 [0..*] Allergies
  • ACC [0..*] Accident information
  • DG1 [0..*] Diagnosis information
  • NTE [0..*] Notes and comments
  • ZAL [0..*] Additional allergy information
  • ZQA [0..1] Questionnaire information
  • ZPI [0..1] Additional person information
  • ZVI [0..1] Additional visit information

Structure B – Person level messages (without encounter information)

Applies to Standard segments Cerner custom segments
  • ADT^A28 (Add person information)
  • ADT^A31 (Update person information)
  • MSH [1..1] Message header

PV1 PV2 ZVI segments.jpg

Patient Visit (PV1), Patient Visit - additional (PV2), & Additional Visit Information (ZVI) segments

Note - Each ADT message containing a PV1 segment (i.e. Structure A messages) results in a new FHIR Encounter resource being created.

The newly created FHIR Encounter is linked to an EpisodeOfCare resource based on the PV1’s Visit Number (this is carried in the Attendance Number field).

If the PV1 Visit Number is new – i.e. has not previously been seen by Discovery – this causes a new EpisodeOfCare resource to be created.

If the PV1 Attendance Number has previously been seen by Discovery, then the Encounter is linked to the existing EpisodeOfCare.
