EU-US eHealth/Health IT Cooperation InitiativeInteroperability of EHR

Work Group

January 15, 2014

Meeting Etiquette• Participants automatically enter the webinar in “listen

only” mode. The organizer will then unmute all participants. We ask if you are not speaking to manually mute yourself• NOTE: VoIP participants have the ability to “Mute”

themselves by clicking on the green microphone. However, if you would like to speak, only you can unmute yourself.

• If you are dialing in using a telephone and NOT using the VoIP you MUST dial the audio pin in order for the organizer to unmute you – if you do not use the audio pin and just push # when prompted the Organizer cannot unmute you

Meeting Etiquette CONTINUED

• If you are calling from a telephone, please do not put your phone on hold. If you need to take a call, hang up and dial in again when you have completed your other call

• This meeting is being recorded• Another reason to keep your phone or

your VoIP on mute when not speaking• Use the “Chat” or “Question” feature

for questions, comments and items you would like the moderator or other panelists to know.

– Access: anyone with link– Privileges:

• “View and Comment” – everyone with link (the one above)• “Edit” – selected

– EU: one designated XML/epSoS PS subject matter expert– US: Mark Roche (for now)

» Above may be reviewed/updated as project continues

• Review Process:– Review/validate mapping outcomes after each phase with community– Review points:

• Mapping completeness• Mapping accuracy• Mapping gaps

EMERGE demo• What is EMERGE?

– EMERGE is a web based application that provides synthetic (dummy) clinical data for ~700 patients

– Clinical Data is available in HTML format (human-readable)– Clinical Data is also available in XML format (machine-readable)

• XML format is compliant with C-CDA R1.1 CCD standard

• Why was EMERGE developed?– To provide EHR vendors in US with examples that will help them more

easily understand C-CDA CCD Implementation Guide (IG) and thus configure EHR to comply with provisions of Meaningful Use Stage 2.

Review Comments: Phase 1, Section-level mapping

14

1. Are all Sections listed?2. Are section names correct?3. Are section LOINCs and OIDs correct?4. Are requirements (R,R2,O) correct?

5. Is mapping complete (section-level)?6. Is mapping accurate (correct)?7. Are there mapping gaps?8. Is mapping clear and unambiguous?9. What is missing?

Review Comments: Phase 1, Section-level mapping (continued)

• Tomasz Adamusiak– Are there additional observations? Vocabularies section is missing

CVX (vaccinations) and CDT (dental procedures)• Jozef Aerts:

– One of the major problems in my opinion is that less than 40% of the EU countries are ITHSDO members which means that in the other 60% SNOMED-CT is not used (except in academia).

– If we count by population, #1, 3 and 4 (Germany, France and Italy) are among these, not being able to use SNOMED. In these countries only a few percent of non-academic hospitals have acquired a license, so in these 60% of the EU countries, SNOMED-CT usage is almost inexistent.

Review Comments: Phase 1, Section-level mapping (continued)

• David Tao – What is missing?– ReadMe – row 24 Clinical Summary Document should not be “synonym” of CCD, but CCD is a

primary example. There are other summary documents (e.g., Transfer Summary) added to CCDA 2.0, and even in 1.1 (Discharge Summary). Row 26 should say “Official name of one type of Clinical Summary Document…”• Should mapping be to CCDA CCD 2.0, given that this EU-US exchange is not constrained by MU? I could lean either way on this, just raising the question. • Not sure what the “US Order” is for. I don’t think there is a prescribed order to the sections, even though they are listed in an order in CCDA (alphabetically, required then optional)• Medications mapping seems problematic. “Prescription” and “Medication Dispensed” according to epSOS 12 (page 87) are for two different documents specific for ePrescription, which are distinct from the Patient Summary. For the PS document, only the Medication Summary is listed (table at line 585). I am not an epSOS expert by any means, but reading the IG leads me to this conclusion. So I recommend that Prescription and Medication Dispensed rows be removed from the mapping, and only Medication Summary be kept. It could be confusing to have all three in a PS document (even though Mark lists Medication Summary as R and the other two as O). IT would be much more straightforward to have a one-to-one section mapping between epSOS PS and CCD. 13.1 says the Medication Summary Section is required in a PS.

16

Review Comments: Phase 1, Section-level mapping (continued)

• David Tao – What is missing?– I don’t understand why List of Surgeries is twice (rows 9 and 10). I only see one section, 13.1.5, in

epSOS PS. It says in 13.1.5.2 that “the Surgical Procedures prior past six months (optional) and shall be used to record the Major Surgical Procedures past 6 months23 (required). Each surgical procedure shall be described using the “Procedure Entry” template 2475 (1.3.6.1.4.1.19376.1.5.3.1.4.19)” To me, that’s just one section with requirements for the dates of the procedures that must be included vs those that may be included, but it’s not two sections. Also, the many-to-one mapping of “Coded List of Surgeries” and “Procedures and Interventions” to the same “Procedures” section in CCD needs further discussion. The CCD Procedures Section LOINC code matches the “Coded List of Surgeries” but not the “Procedures and Interventions.” It can’t have two LOINC codes, so I’m not sure what to do about this. Since Coded List of Surgeries is required in epSOS PS, it is probably the more important one to match. • While History of Present Illness CAN be mapped to CCD Problems, it would be better to map it to History of Present Illness, which is a more direct fit, even though that is not specified by CCD. It is still permitted in CCD since CCD is an open document template. Similarly addition of sections is needed for MU2 anyway

MAPPING GAPS: the four CCD sections at the bottom that don't have a corresponding section in epSOS. If these sections were generated in the US, I suggest that they be included in the transformed document "as is." The epSOS consuming system would not have to do anything processing of the entries in these sections, but must render these sections text in human readable form, as required by base CDA r2. .

Homework: Review Phase 2, Header’ Data Element mapping

18

1. Are template names and OIDs correct?2. Are all Header Data Elements (DE) listed?3. Are DE names correct?4. Are X-Path Statements correct?5. Are requirements (R,R2,O) correct?6. Are Data Types correct?6. Is mapping complete (within header)?7. Is mapping accurate (correct)?8. Are there mapping gaps (sth. Exists in epSoS PS but not in C-CDA CCD

and vice verse)?9. Is mapping clear and unambiguous?10. What is missing?
