DENTAL READ OF FILE 409.68    ICR (4450)

Dental transmits its dental specific data to the AAC
once a week.  The Decision Support staff requested that Dental include all
data elements it needed in the HL7 extracts of VistA that are transmited to
the AAC.  One of the VistA fields requested by the VA-DSS is the OUTPATIENT
ENCOUNTER (#409.68) date and time as well as the internal entry number.  The
dental encounter file (#228.1) has a pointer to the VISIT (#900010) file. PCE
developers have said that for each entry in file 409.68 there should be a
1-to-1 relationship with the VISIT file.  Thus the DENTAL package is
requesting to be allowed to do direct global reads of the "AVSIT" cross
reference on file 409.68 to get the 409.68 record number corresponding to a
VISIT file record number.  Then using the 409.68 record number, a direct
global read will be done for the .01 field of that record to get the encounter
date and time.
