Example model 1 for new dynamic model cdl

Introduction

This is a mapping from the example (here Example_model_1_for_new_dynamic_model) to CDL.

Explanation

The focus on this mapping is to create a repeatable trasnformation based on the ADT material only, with the intent that we could use it as a jumping off place for other types of transformations.

State Model

Text summary: an inpatient admission can either be active, completed, aborted, or nullified. Planned inpatient admissions are considered active. Although other state transitions could be imagined - even between the valid states - the committee has decided that they are not beneficial to model.

Trigger Events

The following trigger events are defined:

Code	Name	Meaning	Candidate State Transition
PRPA_TE412001UV02	Inpatient Encounter Appointment Scheduled	an inpatient admission was scheduled	EncounterAppointment-activate
PRPA_TE412002UV02	Inpatient Encounter Appointment Revised	a scheduled inpatient admission was modified prior to the admission	EncounterAppointment-revise (active only)
PRPA_TE402001UV02	Inpatient Encounter Started	a patient was admitted to an inpatient encounter. If there was an appointment for this encounter then this trigger event also implicitly changes the status of the appointment to completed	EncounterAppointment-complete EncounterEvent-activate
PRPA_TE402008UV02	Link Encounters for Mother and Baby	the sending system has linked the inpatient encounter for a baby to the inpatient encounter for the baby's mother.	ActRelationship w/update mode Added
PRPA_TE402009UV02	Unlink Encounters for Mother and Baby	the sending system has removed the baby to mother link between two inpatient encounters.	ActRelationship w/update mode Deleted
PRPA_TE402010UV02	Link Encounters for Recipient and Donor	the sending system has linked the inpatient encounter for an organ donor to the inpatient encounter for the organ recipient	ActRelationship w/update mode Added
PRPA_TE402011UV02	Unlink Encounters for Recipient and Donor	sending system has removed the organ donor to recipient link between two inpatient encounters	ActRelationship w/update mode Deleted
PRPA_TE402012UV02	Pending Inpatient Discharge	signals of a plan to discharge an inpatient when the patient has not yet left the healthcare facility.	EncounterEvent-revise (info in TE)
PRPA_TE402013UV02	Pending Inpatient Discharge Canceled	signals that a planned inpatient discharge was canceled	EncounterEvent-revise (info in TE)
PRPA_TE402002UV02	Inpatient Encounter Revised	signals that information about an inpatient encounter has changed	EncounterEvent-revise (active or complete)
PRPA_TE402004UV02	Inpatient Encounter Aborted	signals that an inpatient encounter was aborted prior to a normal discharge. Either the practitioner or the patient ended the encounter prematurely.	EncounterEvent-abort
PRPA_TE402003UV02	Inpatient Discharge	an inpatient was discharged	EncounterEvent-complete
PRPA_TE402007UV02	Inpatient Discharge Canceled	signals that a previously-reported inpatient discharge was canceled before the patient was released from the hospital. This trigger event could be either the result of an erroneously-reported inpatient discharge or because a decision was made not to discharge the patient after all.	EncounterEvent-reactivate
PRPA_TE402999UV02	Inpatient Encounter Nullified	signals that a previously-reported inpatient admission notification was sent in error and has been nullified	EncounterEvent-nullify

PRPA_IN402002UV02	Inpatient Encounter Revised	PRPA_TE402002UV02	PRPA_MT402002UV02	An inpatient encounter informer sends this notification when information about an inpatient encounter changes (except for changes to Attending Practitioner, Patient Location and Responsible Organization participations that cause separate interactions). The payload is a complete inpatient encounter record with related acts and participations.
PRPA_IN402008UV02	Encounters for Baby and Mother Linked	PRPA_TE402008UV02	PRPA_MT402008UV02	An inpatient encounter informer sends this notification after the inpatient encounter for a newborn baby is linked to the inpatient encounter for the baby's mother for care and billing purposes. A separate interaction is defined for each type of encounter link because the same two encounters could be linked in more than one way. For example, a mother could also donate part of her liver to her newborn infant. They payload contains enough information to identify the two encounters and an associating ActRelationship with an update mode of "added".
PRPA_IN402010UV02	Encounters for Donor and Recipient Linked	PRPA_TE402010UV02	PRPA_MT402008UV02	An inpatient encounter informer sends this notification after the inpatient encounter for an organ donor is linked to the inpatient encounter for the organ recipient for care and billing purposes. A separate interaction is defined for each type of encounter link because the same two encounters could be linked in more than one way. For example, a mother could also donate part of her liver to her newborn infant. The payload contains enough information to identify the two encounters and an associating ActRelationship with an update mode of "added".

PRPA_IN402012UV02	Inpatient Discharge Pending	PRPA_TE402012UV02	PRPA_MT402002UV02	A user initiates a notification that an inpatient will soon be discharged. The payload is a Revised Inpatient Encounter message type. In this notification interaction the encounter remains in the event mood and the statusCode remains active. However, discharge-related attributes and associations, if valued, have the following interpretations...
PRPA_IN402009UV02	Encounters for Baby and Mother Unlinked	PRPA_TE402009UV02	PRPA_MT402008UV02	An inpatient encounter informer sends this notification after an erroneous link between the inpatient encounter for a newborn baby and the inpatient encounter for the baby's mother was deleted.

CDL Mapping

Following are the mapped elements between CDL and the HL7 specification

• In CDL, a Top Level "ADT Notification" Choreography is created that will call other Choreographies. The call will be made based on the states of variables.
• The CDL.Variables at the choreography level are named for the HL7.TriggerEvents (1..1).
• All CDL.Variables that map to HL7.TriggerEvents are Booleans. Only one TriggerEvent can be "true()" at any one time
• The CDL.Variables named for HL7.TriggerEvents are assigned values in CDL.components that reflect the underlying state transition. For example, EncounterAppointment-activate.
• The CDL.Variables description is that of the HL7.TriggerEvent.Name (from the table)
• HL7.Interaction is created as a CDL.Choreography (top-level choreography; 1..1)
• The Choreography is modeled as first, an CDL.interaction that realizes the SchedulingApplicationToSchedulingManager CDL.Relationship.
• The subsequent CDL.interaction is to model the actual notification. This CDL.Interaction realizes the CDL.Relationship InformerToReceiver.
• The CDL.Notification uses the HL7.Payload. The CDL.MessageType is tied to the CDL.InformationType, which is described as, for example, PRPA_MT412001UV02.

Issues with the CDL Mapping

• How does a participant set a variable? Does the variable have to be free?
• Is the "Conditional" Grouping the correct one to model which state transition (via global variables) has just been triggered? How is the choice "made"? What is the expression written in?
