LINKTools® INBOUND HL7 ADT Configuration Example

Exercise: Let take a look at the following ADT^A08 message below:

The Following is HL7 ADT^A08 message definition:

"Event A08 is issued when patient information has changed. For example, a change of address or a name change, an A08 is recommended to update fields that are not related to any other trigger event. "

The Update Patient Information message is as follows:
"MSH..EVN..PID..[{NK1}]..[PV1]..[PV2]..[{AL1}]..[{DG1}]..[{IN1}]..[ACC] "
Where MSH, EVN, PID are mandatory and the rest of the HL7 segments are optional

There are a few options to build your Interface template using LINKTools® Mapper.

1- Build the interface template that includes all HL7 segments per HL7 definition above or
2- Build the template according to what you received from the HIS or
3-Use the available LINKTools® pre-built Mapper template and adjust to reflect data field receive by the HIS

Let take a look at the ADT^A08 example above, we can see that we have received 4 HL7 segments in the message: MSH, EVN, PID, PV1.

The following is example steps of creating Mapper interface template

1- Launch the LINKTools® Mapper from the desktop shortcut icon, and then click on the
[Mapper/Config Icon] to access the Mapper configuration dialog box
2- From the Mapper configuration dialog box start building your interface template by filling out information in this sequence: left to right top to bottom as is filling out a form
3- At [Input] column click on the "…" to browse to the LINKTools® interface folder (default: C:\LINK\OrderR\*.ord), File Format default is HL7
4- At [Output] column to the right click on the "…" to browse to the LINKTools® interface folder (default: C:\LINK\OrderS\*.XML) File Format by default is XML
5- Check the [Write Out] box on the top right (Figure 1), click on [Option] button to the right of the [Format] box, check the HL7 Segment Tag box, and then click [OK].
6- At [DBF] column click on the "…" to browse to the LINKTools® Interface folder to set path of your intermediate database (default: C:\LINK\OrderDB\Order.DBF)
7- At [Segment] column, click on the [HL7] button on the right to access the LINKTools® HL7 Library. This is where you select your HL7 Segments for your Interface.
Select your HL7 message segments for your template in this order MSH, EVN, PID, PV1 move the segment from the left pane to the right pane. When finish click [OK] to go back to the configuration screen (Mapper default MSH, EVN, PID, PV1)
