Hi Dave,
As you have mentioned in your post, the actual implementation of data
flow will vary from one organization to another but I can give a quick
rundown of our facility. When a person arrives to ER, he or she is
registered with our HIS system (AHS) as ADT 04 transaction with ER
location codes, and this transaction is sent to our ER clinical system
as well as our main clinical system such as MACS/SCM. At any given
moment ADT information could be updated via A08 transaction, which
will also end up in previously mentioned clinical systems. Now, if
patient is required various tests such as blood or Xrays and depending
on the nature or complexity of the tests, the orders (ORM) will be
sent from either ER clinical system (HMED) or main clinical system
MACS/SCM to our ancillary systems like IDX or Sunquest. Next comes
results (ORU) from ancillary systems to MACS/SCM/HMED. However, if
doctors finally decided to admit the patient, he or she will be
"Transfered from outpatient to inpatient location), with ADT 06. This
transaction is of course is sent to other systems as well. Finally,
say 3 days later, patient is discharged with A03 transaction. If
however, patient is released before A06 transactions is generated,
then simply ADT 03 will suffice the entire flow.
If need more detail, please let me know.
