Adding missing PID data to message using Q21

Question

Question

Martin Browne · Nov 4, 2019

Hi,

I’m working on a project to add specific PID data to an ORU_R01 message by querying our patient system and adding it to the ORU. Here is what I have
managed to do thus far:

-   Received ORU_R01 message
-   Created Q21 message using the PID data included in the ORU message and sent to patient system to query.
-   Received a K21 message with the required PID data

I’m stuck at this point now. I want to add a specific piece of the K21 PID data (highlighted below) to the original
ORU_R01 PID and was hoping you would be able to assist.

I am doing this using Studio. I want to avoid using a BPL. Could anyone help?

Here are me messages:

After you receive the K21 response you could get the patient identifier that you need by looping through all the identifiers that are included in the K21 PID:3(X).1 field and extract the id that you want only if the PID:3(x).4 has a specific value.

Then you could create clone of the ORU message and you can set the value of the PID using the identifier extracted from the K21 response.

For example:

If your business process is receiving the ORU message then an example OnRequest method could be like the following one:

Method OnRequest(pRequest As EnsLib.HL7.Message, Output pResponse As Ens.Response) As %Status
{
                SET sc=$$$OK
                //assumes that you have created the Q21 here…
                SET sc=..SendRequestSync("PASSystem", Q21msg,.K21Resp)
                IF sc
                {
                                For i=1:1:K21Resp.GetValueAt("PIDgrp.PID:3(*)")
                                {
                                                IF K21Resp.GetValueAt("PIDgrp.PID:3("_i_").4.1")="5"
                                                {
                                                                SET PatID=K21Resp.GetValueAt("PIDgrp.PID:3("_i_").1")
                                                }
                                }
                                SET newORU=pRequest.%ConstructClone()
                                IF $GET(PatID)'="" SET sc=newORU.SetValueAt(PatID,"PIDgrpgrp(1).PIDgrp.PID:3(1).1")
                                //now here you can set the pResponse to be the newORU or you can send it to another Business Host.
                                SET sc=..SendRequestSync("DestinationOfTheFinalORU", newORU ,. newORUResp)
                                SET pResponse=newORUResp
                }
                Quit sc
}

You can do like this as well in case you want to use DTL only ..

<transform sourceClass='EnsLib.HL7.Message' targetClass='EnsLib.HL7.Message' sourceDocType='2.3.1:ADT_A01' targetDocType='2.3.1:ADT_A01' create='copy' language='objectscript' >
<assign value='$extract(source.{MSH:Receivingfacility},1)' property='target.{MSH:Receivingfacility}' action='set' />
</transform>
}

I am using MSH:6 but you can use anything here.

In case you need to use any use written function you can create a class extending "Ens.Util.FunctionSet."

Any class method we write in the class will be added in your DTL method option .
