| GENERAL DESCRIPTION |
This IA is for the Master Patient Index (MPI) Health Eligibility
Center (HEC) Enumeration project.
There are approximately 29,000 patient entries, identified at the HEC
from legacy systems, for which the primary site is not known on the HEC.
These patients need to be identified on the primary VistA system so
they can be added to the 1.6 million HEC patients to be assigned ICNs.
This needs to be done prior to the beginning of the HEC enumeration.
Information for these patients may be available in the NDBI POINTER
CONVERSION file (#17002.2) on the primary VistA system.
From the Master Patient Index (MPI), a remote request can be sent to
an integrated facility for the identified HEC legacy patient entries.
A Remote Procedure Call (RPC) on the local VistA system will search
the NDBI POINTER CONVERSION file (#17002.2) and return to the MPI the
DFN for that entry in the primary site if it is available. This RPC
will only be used at selected integrated sites.
The Master Patient Index VistA package references a National Database
Integration global: ^A7RCP.

GLOBAL DESCRIPTION |
A7RCP('B',,IEN) |
The 'B' cross reference is used to get the site IEN.
|
A7RCP(IEN,1,2,1,DFN,1) |
Given a specific site IEN and DFN from the legacy site, this
node contains the DFN for the patient at the primary site in
piece 1, which is a pointer to the PATIENT file (#2).
