Currently, the Pharmacy Benefits Management (PBM) extract blocks the
Problem:
========
Several facilities were reporting that selected laboratory tests were not
present in the Structured Query Language (SQL) database used by PBM to
perform medication use safety surveillance, while the source data was
clearly available in local VistA and Computerized Patient Record
System (CPRS). Upon further investigation, it was discovered that the
laboratory results did transmit as expected, but the lab test name did
not, resulting in database search failures.
transmission of chemistry lab results for "Employee Veteran" and
Resolution:
===========
The source of the error was traced to laboratory tests with a National
Lab Test (NLT) Name containing a tilde (~) character. This character
is also used as the delimiter in HL7 message processing, and the extra
tilde caused the routines that parse the transmitted data to be offset by
one data element. The correction is to translate any tilde characters in
the NLT name into an underscore (_) character, so that any remaining
tilde characters are solely present as the expected HL7 delimiters.
"Employee Non-Veteran." This patch addresses the New Service Request (NSR)
#20080810 to transmit the chemistry lab results for "Employee Veteran"
via Health Level 7 (HL7) messaging to the PBM extract database while
continuing to block the chemistry lab results for "Employee Non-Veteran."
This patch also addresses the following.
