Adding new OBX segments

[Patricia Smith]

Hello All,

I’m working on radiology result messages ORU^R01.  Currently our RIS system just send the text of the report in the OBX segments but I would like to add a header to the text that displays Patient Name, Exam Type, and more for a COLD feed into HPF. I want to build this header from information in the OBR, PID and PVI segments.  I’m having trouble in my Xlate building this header in the OBX segments.  How do I add the new OBX segments at the beginning of the OBX iteration?  This header that I want to build will always have 5 lines. So I will need 5 new OBX segments at the beginning.  Any help will be greatly appreciated.

Thanks,

Patricia

Here is part of an example message I’ve been working on.

Hi Patricia,

You will need to keep track of the number of OBX-segments that are written. I assume that you’re using the variable %s1 to transfer the OBX segments from one format to the other (both HL7?).

Now you first need to initialize your own variable; say %s9:

COPY =0 -> $%s9

(By using $%s1 you can manipulate the variable).

Then you build your first header line:

COPY =FT -> 1(0).1(0).1(0).OBX(%s9).#2

COPY =GDT => 1(0).1(0).1(0).OBX(%s9).#3

COPY {=distal first through third metatarsals} -> 1(0).1(0).1(0).OBX(%s9).#5

After which you increase the %s9 variable:

MATH ADD =$%s9 =1 -> $%s9

Repeat this for all header lines.

When it’s time to copy all the real OBX-segments from input to output, use the iterate variable (I assumed %s1) in your source-path and %s9 in you destination-path. Don’t forget to increase %s9 at the end of your iterate!
