Provider ID

[Scott Smith]

I am looking for the syntax for reading only the provider ID from OBR 16.  I cannot seem to remember the syntax for getting only value before ^.  Anyone?

Scott,

Within in an Xlate, you just need to map at the component level; i.e.

COPY 1(0).1(0).0(0).OBR(0).00539(0).[0] –> 1(0).1(0).0(0).OBR(0).00539(0).[0]

where [0] gets you the first component of the field….

If you are doing this via tcl, then once you’ve split the segment into fields, you now need to split the field into components based on the component separator.

Hope this helps.

Jim,

Actually I doing thru TCL.  I thought I found a piece of code, but it is still pulling the whole field instead of data before first separator.  Here is what I have so far:

         # get the field separator from the hl7 message

           set fieldSeparator [crange $msg 3 3]

           # get the field from the hl7 message

           set OBRsegment [getHL7Segment $msg OBR]

           set drNumber [getHL7Field $OBRsegment 16 $fieldSeparator]

set obrFlds [split $OBRsegment $fieldSeparator]

            set obr16 [lindex $obrFlds 16]

echo $obr16

   set drNumber [crange $drNumber 0 3]

  set drNumberList $drNumber

echo drNum:<$drNumber>

Any help?

Scott;

You need to also define subfieldseparator:

set sfs [cindex $msg 4]

and then split the field 16 on sfs.

Quick & Easy:

set drNumber [lindex [split [getHL7Field $OBRsegment 16 $fieldSeparator] ^] 0]
