Failed OBX Iteration

[Gena Gill]

I’m drawing a blank on this one.

Try running your inbound messages through the HL7 testing tool and pay special attention to the OBX parens. I’ve found that that has helped me to get my head around some of the iteration problems I’ve had in the past.

Yes, I’ve done that, but still cannot nail this down.  I’ve actually had issues with this on other translations since upgrading to 5.6, but don’t know if it’s a problem in Cloverleaf, or a problem with me as I’m doing more complex translations than I have in the past.

What does your variant look like? Is the OBX part of a group?

[Gena Gill]

I’m just using the version 2.3 ORU variant.  I’ve not created a special variant.  It’s not part of a group.

Here’s a sample from the testing tool:

1(0).1(0).1(0).OBX(0).#3(0).[2].[0]  :  >LA01<

1(0).1(0).1(0).OBX(0).#4(0).[0].[0]  :  >1<

1(0).1(0).1(0).OBX(0).#5(0).[0].[0]  :  >Specimen/Source: SPUTUM/SPUTUM<

1(0).1(0).1(0).OBX(0).#14(0).[0].[0]  :  >200902021140<

1(0).1(0).1(0).OBX(0).#15(0).[0].[0]  :  >SKAGGS<

1(0).1(0).1(0).OBX(0).#15(0).[1].[0]  :  >SKAGGS REGIONAL HEALTH CENTER<

1(0).1(0).1(1).OBX(0).#1(0).[0].[0]  :  >2<

1(0).1(0).1(1).OBX(0).#2(0).[0].[0]  :  >TX<

1(0).1(0).1(1).OBX(0).#3(0).[0].[0]  :  >REPORT<

1(0).1(0).1(1).OBX(0).#3(0).[1].[0]  :  >Clinical Report<

1(0).1(0).1(1).OBX(0).#3(0).[2].[0]  :  >LA01<

1(0).1(0).1(1).OBX(0).#4(0).[0].[0]  :  >2<

1(0).1(0).1(1).OBX(0).#5(0).[0].[0]  :  >Collected: 02/02/2009 11:40<

1(0).1(0).1(1).OBX(0).#11(0).[0].[0]  :  >V<

1(0).1(0).1(2).OBX(0).#1(0).[0].[0]  :  >3<

1(0).1(0).1(2).OBX(0).#2(0).[0].[0]  :  >TX<

You can see on the first iteration, that OBX 11 was nulled, yet the second iteration the V is still in that field.

I think your Test Tool output is showing you that OBX is iterating at the GROUP level, not segment level.

[Max Drown (Infor)]

I think you need to iterate on a group.

1(0).1(0).1(1).OBX(0).#11(0).[0].[0]

For a segment looping, you would see OBX(n) like OBX(0), OBX(1), OBX(2), etc.

In this case, you have the iteration happening on 1(0).1(0).1(n).

Also, note that I suggested the HL7 testing tool, not the XLT testing tool. The HL7 testing tool will help you visualize the looping.

OK, I’m a dork.  Yes, you guys are right, this IS a group.  I also found out, while looking at some other things that I need to create a variant specifically for this translation, so I should be able to fix my problem.

Thanks for your help!
