      I have a situation where i have obx like

      OBX|2|NM|INR^INR VALUE||1.00     THERAPEUTIC: (FOR STABLE ORALLY ANTICOAGULATED   PATIENTS)          2.0-3.0 DVT/PE/MI/TIS/HT VAL/VAL HT DIS/ATR   FIB  2.5-3.5 CARDIO EMBOLUS/MECH HT VAL||(0.9-1.1)||||||

      if obx-5 has non numeric value like

      1.00     THERAPEUTIC: (FOR STABLE ORALLY ANTICOAGULATED   PATIENTS)          2.0-3.0 DVT/PE/MI/TIS/HT VAL/VAL HT DIS/ATR   FIB  2.5-3.5 CARDIO EMBOLUS/MECH HT VAL

      then I need have

      obx-5 as 1.00 and the rest of the text in NTE.

      Any ideas.

          Try

          Copy OBX.5 -> @numeric @rest

          with this tcl:

          Code:

          lassign $xlateInVals field
          set first_space [string first ” ” $field]
          set number [string range $field 0 [expr $first_space – 1]]
          set txt [string range $field $first_space end]
          set xlateOutVals [list $number $txt]

            Thanks for the info Robert,

            when I did that none of the values are coming into OBX5

            1(0).1(0).1(0).OBX(0)

              Thanks again Robert

              I changed the code a little bit and i was able to seperate the number from the text. Thanks a lot.

                Can you tell me how I can handle this if i have repeating values i OBX5 field.

                Ex:

                85    The MDRD equation for estimation of GFR (eGFR) was^ ~ developed in apopulation of adults (>19 yrs old)^ ~ with slowly declining or stablereduced kidney^ ~ function.  The MDRD equation has not been validated^ ~ inpatients >70 years of age and should not be used^ ~ to predict eGFR inunstable patients or children.

                  This is a very weird repeating field… Repeating field separator is a ‘~’ if I’m correct, and here it looks like you have ‘^ ~’.

                  I would remove the ‘^ ~’ from the remaining text as it has no purpose in the NTE-field. You need just one extra regsub in the code to replace the ‘^~’ by a space:

                  Code:

                  lassign $xlateInVals field
                  set first_space [string first ” ” $field]
                  set number [string range $field 0 [expr $first_space – 1]]
                  set txt [string range $field $first_space end]
                  regsub -all {^ ~} $txt ” ” txt
                  set xlateOutVals [list $number $txt]

                    Bala,

                    It looks like they used the tilde character, ~, instead of a line break. Replace them with a line break.

                      Bala,

                      Th answer depends on the value of OBX-2. If that has a data type that has components in its structure, then each repetition is a 2 component field.

                      In this case, the second component is not populated but the separator is in place (the ^). This is fairly common for some systems.

                      So in your Xlate inside the ITERATE on the OBX-5 field, you need to reference the field with component notation  eg: 1(0).0(0).OBX.#5(%fxx).[0] <– This s acontrived example %fxx would be your field repeition counter assigned in the OBX-5 ITERATE. The key here is the .[0] at the end of the notation which refers to the first component of the field.

                      If they also populated the second component then to address it you would use 1(0).0(0).OBX.#5(%fxx).[1].

                        Thanks for the responses let me try and see which one works.

                          I used suggesting from Jim’s method, since I know how many times the field is going to repeat i captured it and concatinated it to NTE.

                          This is not as clean as it should be but it works. If any one has any other suggestions please do post it.

                          Thanks
