At Nebraska we have rolled out our Epic encounter data and have created mapping 
to the PCORI valueset for encounter types.  Epic has provided an unfortunate 
excess of encounters such that administrative, billing and non-patient care 
events are all assigned as encounters.  Segregating between ED and 
hospitalizations as well as ambulatory surgery is a bit convoluted but we have 
sorted out the Clarity data structures necessary to do so.  At this time we are 
planning to map the PCORI valueset data to a metadata element specifically for 
PCORI queries
PCORI\Encounters\Encounter type
When we have a LOINC code assigned from Regenstrief, we will add the LOINC 
basecode

In some respects it would be cleaner to use LOS coding to identify service 
events but then non-billable patient care encounters would be ignored.

Nate Apathy - how does Cerner record pateitn care encounters?

Subject: Encounter_num

Just hopefully a quick question to the group.  How are everyone's encounter_num 
field being defined(or filled in) in the observation fact table?  From my 
understanding, those that have EPIC this is already sort of defined in the 
source data (I think), correct?  At Marshfield, unfortunately we don't have 
anything like that in our source data.  In the past, we have created encounter 
numbers for our VDW as part of the HMORN, and we have based it off of other 
information that we have such as MHN, date, provider, facility, etc.  I'm just 
curious how this is defined for EPIC sites and for non-EPIC sites.

Also, related to my question above, regarding the annotated data dictionary 
that we need to fill out - in particular the encounter type (which is part of 
the encounter, diagnosis, and procedure content areas).  Are other sites 
currently loading these encounter types(AV, ED, IP, etc.) into i2b2? If so, 
what fields are they being stored in?

Any info would be greatly appreciated here at Marshfield.

Thanks much,
Jay
