Re: [Hardhats] Re: How to trigger an ADT message upon "Admit a patient" in VistA?
Jason,
One component to recognize is that
1) VistA is capable of Object-Oriented "messaging" and "events" through the protocol unwinder.
2) a Protocol provides a "hook" similar to a call-back in other object oriented systems to allow your
own code to be run if you properly subscribe to the event.
3) a Trigger is a data dictionary hook that allows your code to be run when a change occurs to a data value for an entry in the file. This is a standard FileMan process.
4) There are certain fields, especially in the PATIENT File #2 that have trigger code which call the protocol unwinder to "fire" an event.

This cross-reference will check the IVM PATIENT
file to see if a change to this field will
require transmission to the IVM Center. If it
does, the IVM PATIENT file entry's TRANSMISSION
STATUS will be set to 0 and the nightly
background job will transmit the updated
information.

Also, if this field is edited, this
cross-reference will check to see if the
patient requires a financial query to be sent
to the IVM Center (Data Collection Division
(DCD).

This cross reference is used to remember that
changes were made to the PATIENT file (#2)
outside of the Registration process. Execution
of this cross reference will create an entry in
the ADT/HL7 PIVOT file (#391.71) and mark it as
requiring transmission of an HL7 ADT-A08
message.

The local variable VAFCFLG will be set to 1 if
the cross reference is not executed because the
change is being made from within the
Registration process.

Execution of this cross reference can be
prevented by setting the local variable VAFCA08
equal to 1.

The local variable VAFCF is used to identify
the field edited. This data is stored in the
FIELD(S) EDITED (#2.1) field in the ADT/HL7
PIVOT file (#391.71).

This cross reference is used to remember that
changes were made to a monitored data field in
the PATIENT File (#2) required for a vendor
RAI/MDS COTS system. Execution of this cross
reference will create an entry in the ADT/HL7
PIVOT file (#391.71) and mark it as requiring
transmission of an HL7 demographic A08 update
message to the COTS interface.

The local variable DGRUGA08 will be set to 1 if
the cross reference is not to be executed as
part of a re-indexing.

FIELD INDEX: ADGFMD03 (#847) MUMPS I ACTION
Short Descr: This x-ref calls the DG FIELD MONITOR event
point.
Description: This cross reference activates the DG FIELD
MONITOR event point. Applications that wish to
monitor edit activity related to this field may
subscribe to that event point and take action
as indicated by the changes that occur. Refer
to the DG FIELD MONITOR protocol for a
description of the information available at the
time of the event.

The last trigger, which calls DGFCPROT is one example of this.

A part of the DGFCPROT routine has:

As you can see, there is the setup for calling TaskMan to invoke the DG FIELD MONITOR
entry in the PROTOCOL file #101 by calling EN1^XQOR.

NAME: DG FIELD MONITOR ITEM TEXT: DG Field Monitor
TYPE: extended action CREATOR: MARSHALL,RICK
PACKAGE: REGISTRATION
DESCRIPTION: This protocol is an event point which monitors the editing of
fields in DG* application files. At the time of this event point, the
following variables will be present in the environment:

Variable Description
-------- -----------------------------------------------
DGDA DA array as exists during Fileman editing
DGFILE File or subfile number where changed field resides
DGFIELD Number of changed field
DGTYPE Type of cross reference action (ADD, DELETE or UPDATE)
DGDTH Date/time of change in $Horolog format
DGUSER DUZ of user that made the change
DGOPT Current menu option in "option_name^menu_text" format
DGX X array as documented for Fileman new style x-refs
DGX1 X1 array as documented for Fileman new style x-refs
DGX2 X2 array as documented for Fileman new style x-refs

This protocol is triggered by "listener" cross references on selected fields.
By employing logic such as "If DGFILE=2, DGFIELD=.361, DGTYPE="ADD", then...",
subscribers to this protocol may take action based on edit activity which
involves those fields.

This event point is designed to occur only once per field editing activity.
The DGTYPE variable can be interpreted as follows:

o ADD transactions indicate that data has been added to a field
that was previously null. The DGX, DGX1 and DGX2 arrays will
contain the Fileman X, X1 and X2 arrays (respectively) as
documented for the execution of 'SET' logic.

o DELETE transactions indicate that previously existing data has
been deleted without being replaced. The DGX, DGX1 and DGX2
arrays will contain the Fileman X, X1 and X2 arrays
(respectively) as documented for the execution of 'KILL' logic.

o UPDATE transactions indicate that existing data has been deleted
and new data has been filed. The DGX, DGX1 and DGX2 arrays will
contain the Fileman X, X1 and X2 arrays (respectively) as
documented for the execution of 'SET' logic.

The naming convention used for these 'new style' cross-references for this
Patch are as follows:

1. All names will begin with the letter "A" to denote a non-lookup MUMPS
cross-reference.

2. The next characters identify the name space (i.e. Registration ="DG").

3. The next two characters identify the field monitor utility ("FM").

4. The next character will be "D" if the field contains a decimal. If
there is no decimal, there will not be a "D" character.

5. The next characters identify the field number.

The establishment of this naming convention is intended to assist with the
easy identification of the field monitoring utility as implemented across
multiple field definitions. It should be followed as additional instances of
this utility are distributed.
