Sites may use the Reference Laboratory package as a unidirectional interface,
which only transfers laboratory results back to the ordering
facility. Other sites may use the package as a bidirectional
interface to transmit their orders electronically as well
as receive results using the auto instrument option of the
RPMS Laboratory Package.
Urban, Tribal, and IHS facilities using the RPMS Laboratory
System may use a unidirectional interface if laboratory staff
does not have time to accession and track all reference laboratory
data. Sites will select to use either a unidirectional or
a bidirectional interface after the software installation
when site parameters are set.
Unidirectional
A unidirectional interface passes laboratory data from the
Reference Laboratory to the Patient Care Component (PCC) database,
if it meets all criteria of patient and test identification.
Do not interpret the laboratory data stored in the PCC as
a replacement for the hard copy laboratory reports issued
by the Reference Laboratory and filed in the patient charts.
The hard copy report remains the legal laboratory report.
The laboratory data transmitted to PCC via the interface is
designed as a replacement for PCC data entry and provides
an abstracted view of laboratory results suitable for health
summary display, database searches, and clinical overview.
Bidirectional
Facilities using the RPMS
Laboratory Package may use the reference laboratory interface
in bidirectional mode. Test orders placed in the RPMS Laboratory
System or Electronic Health Record (EHR) are exported to the
designated Reference Laboratory when accessioned. Test results
are released by the Reference Laboratory and may be reviewed
and verified using the Enter/Verify Data (Auto Instrument)
option in the Processing menu of the Laboratory Package. If
a site uses a bidirectional interface, the data stored in
the laboratory files duplicates the data sent by the Reference
Laboratory and is available in all normal laboratory report
options as well as from PCC and the Electronic Health Record
(EHR).
