Iterate on table in OBX

[Anonymous]

Hi,

I am iterating on a table. OBX 3 and OBX 5. First I do is Iterate on OBX 5. If the value is found, I want to copy the table lookup value to OBX 3. If the value is not found, I want to leave the OBX 3 value (whatever it was) to be left alone.

So my next iterate will be on OBX 3. If the value is found (which it will), I am using the table to complete the translation and send the resulting HL7 to receiving system.

But how do I make the “Leave me alone” thing with the table.

Hope someone has done this before. If it comes to a point where I wld have to write the If statements for all those “Leave me alone” values, I can do that. I want that to be last option.

Thanks,

If I am understanding correctly,  Then I would do a Table lookup of OBX5 and store the result in a temporary variable @obx5 or something.

Then you could do if logic on the @obx5 and if the result is NOT @null — or your Table default value (if your using a default value)

Then you can map @obx5 to Obx3.

I hope this makes sense.

I am not able to get to “Leave me alone” part.

When I first do, translate OBX3 to value from table based on OBX5, it is nulling the OBX3 part if it doesnot have a table mapping.

Like,

OBX3 = leavemealone

OBX5 = test. I donot have mapping for test in the table.

When I iterate over OBX5 using the table, since test is not available in the table,

my HL7 at this time has OBX3 as null or no value.

I don’t want that to happen.

So in other words, if I don’t find words in the table for OBX5, I want OBX3 to be left as is which in this case is “leavemealone”

Let me know.

Thanks,

Hari,

You could make the destination field of the table lookup a temporary field and make the default value of the table “NOTFOUND” (or your favorite alternative).  Then put an if action to test for not found.  If not found then leave alone (actually you’ll probably just move the field from source to dest), else make the change.

Hope this helps.

Ryan’s logic should work:

copy @null -> @obx5

table 1(%?).1(%?).OBX(0).#5 -> @obx5

if @obx5 ne @null

 copy @obx5 -> 1(%?).1(%?).OBX(0).#3

note: %? = your group iterate variables
