When a result returns from a send-out laboratory containing results with a reference range with a negative value, VistA Lab parses the values erroneously and renders the range as a positive value. Associated NSR(s): ------------------ N/A Associated ServiceNow ticket(s): ========================== 1. INC4872523 - Reference Ranges With Negative Values Blood Bank Review: ================== EFFECT ON BLOOD BANK FUNCTIONAL REQUIREMENTS: Patch LA*5.2*99 contains changes to a package referenced in ProPath standard titled: BBM Team Review of VistA Patches. This patch does not alter or modify any VistA Blood Bank software design safeguards or safety critical elements functions. RISK ANALYSIS: Changes made by patch LA*5.2*99 have no adverse effect on Blood Bank software functionality, therefore RISK is none. Associated NSR(s): ================== N/A Participating Test Sites: ========================= Minneapolis VAMC St Cloud VA HCS Northport VAMC Remedy Overview: ================ 1. INC4872523 - Reference Ranges With Negative Values Problem: -------- When a reference laboratory sends results for a lab test with a reference range with a negative value like: -9.9 TO +3.3, VistA parses the ranges improperly. The reference range is contained in the incoming HL7 OBX segment: OBX|7|NM|085937^IgG, Syn Rate,CSF^L^14116-8^IgG synthesis rate^LN| |33.4|mg/day| -9.9 - +3.3|H||N|F|20190305||201903010958|01 Vista Lab is reporting out the reference range as "<=9.9" which is incorrect. The reason that the current reference range parsing is not working is the program uses the "-" to piece out the reference low and the reference high. When the code pulls the 1st piece (reference low) delimited by a "-", it gets a null value. Pulling the 2nd piece (reference high) returns "9.9" which is not negative and is not the reference high. Resolution: ----------- The routine ^LA7VIN5A is modified to determine whether either or both of the reference ranges are negative and extract them appropriately. Routines: LA7VIN5A Components: =========== N/A Installation Instructions: ========================== The install time for this patch is less than 2 minutes. This patch Can be installed when Laboratory users are on the system. NOTE: Kernel patches must be current on the target system to avoid problems loading and/or installing this patch. 1. Use the 'INSTALL/CHECK MESSAGE' option of the PackMan menu. This option will load the KIDS patch onto your system. 2. The patch has now been loaded into a Transport global on your system. You now need to use KIDS to install the transport global. 3. On the 'Kernel Installation & Distribution System' Menu (KIDS), select the 'Installation' menu. 4. Use the 'Verify Checksum in Transport Global' option and verify that all routines have the correct checksums. 5. On the KIDS menu, under the 'Installation' menu, use the Following options: Print Transport Global Compare Transport Global to Current System Backup a Transport Global To preserve a copy of the routines exported in this patch prior to installation, you should use the 'Backup a Transport Global' option at this time. You may also compare the routines in your production account to the routines in the patch by using the 'Compare a Transport Global to Current System' option. 6. Use the 'Install Package(s)' option under the 'Installation' Menu and select the package 'LA*5.2*99'. If prompted 'Want KIDS to INHIBIT LOGONs during the install? YES//, choose 'NO'. If prompted 'Want to DISABLE Scheduled Options, Menu Options, And Protocols? YES//', choose 'NO'. Back-out/Rollback Strategy: -------------------------- In the event of a catastrophic failure, the Facility CIO may make the decision to back-out the patch. It is imperative that you have performed a backup of the routine included in this patch prior to installation. The back-out plan is to restore the routine from the backup created. No data was modified by this patch installation and, therefore, no rollback strategy is required. To verify the back-out completed successfully, ensure the checksum matches the pre-patch checksum from the patch descriptions. Routine Information: ==================== The second line of each of these routines now looks like: ;;5.2;AUTOMATED LAB INSTRUMENTS;**[Patch List]**;Sep 27, 1994;Build 3 The checksums below are new checksums, and can be checked with CHECK1^XTSUMBLD.
