[HAPI-devel] HAPI having a problem with ORM segment

[stevmon <ste...@si...>]

I am not certain of the contact for my question.  If this is not the
correct place, please refer me to whomever - and TIA.

I am having a problem with some messages that I don't think it is
correct behavior of the HAPI engine and the testpanel application.  We
are trying to interface with a MedStar system to receive Orders message
and populate the patient and exam exam tables used by another
application.  You should be able to duplicate the problem by pasting the
following message into the testpanel application and parsing it.  Here
is an excerpt from the raw_messages.log file:

MSH|^~\&|MedStar||||200407261635||ORM^O01^|1833|P^|2.3.1|||||||English|
PID|001||0000004164||Patient5^Pending||20040404|F||Black|2342^23423^MIami^FL^44444^|||||S|||000000000|||||||||||
PV1|001||^^^50||||^^^^|^^||||||||||||||||||||||||||||||||||||200405171500||||||||
ORC|NW||1770||||||||||||||50|||||||^^^^^
OBR|001||1770|Default
reason||||||||||||^^^|||||||||||^^^200405171500||||||||||||||||||


MSH|^~\&|||||20040726153600.968-0600||ACK|233|P|2.3.1
MSA|AE|1833|Couldn't Read PID Message Header: PID does not exist in the
group ca.uhn.hl7v2.m
ERR|^^^207&Application Internal Error&HL70357

If I copy and past the raw message into the testpanel application, it
fails to parse the segments correctly.  HOWEVER if I change the message
type to ADT^O01 it will parse correctly - and if I change the message
type to ORM^001 it will still parse the message correctly so the the
PID, PV1, ORC and OBR segments can be retrieved correctly.  Another
excerpt from the logging file after I do this:

MSH|^~\&|MedStar||||200407261635||ORM^001|1833|P|2.3.1|||||||English
PID|001||0000004164||Patient5^Pending||20040404|F||Black|2342^23423^MIami^FL^44444|||||S|||000000000
PV1|001||^^^50|||||||||||||||||||||||||||||||||||||||||200405171500
ORC|NW||1770||||||||||||||50
OBR|001||1770|Default reason|||||||||||||||||||||||^^^200405171500


MSH|^~\&|||||20040726154142.218-0600||ACK|234|P|2.3.1
MSA|AA|1833

Note that the message that is logged has been slightly altered during
the process of changing the message type back and forth.  I have added
my own message handler based on the simple_server and that seems to work
very well once the message is interpreted and parsed into components
correctly.

I am trying to get some other examples from elsewhere and have tried
some messages found on the internet including so,e from linkmed.com. 
The ORM tag seems to cause some confusion but a simple edit to ADT and
everything seems fine (in some cases, it does appear that I cannot
toggle back to ORM or the message will fail to parse again.)

As usuall this project needs to get done very soon and I would
appreciate a rapid response very much!

Thanks
Stev
