2. Topics IEEE Std 11073-10101 and NIST RTMMS Update
IEEE P b – new terminology
IEEE P c – events and alerts
NIST RTMMS – accelerating numeric code assignments

3. IEEE Std 11073-10101a and NIST RTMMS update
NIST RTMMS has been updated with a nomenclature and was used for limited testing at IHE NA Connectathon.
Co-constraints (units, enums and sites) for new a terms have been uploaded to NIST RTMMS are available, and should be available this week (October 11-13, 2016).
The second-generation harmonized Rosetta, hRTM2, combines the ‘old’ and ‘new’ 10101a terms and co-constraints, and use aECG lead offsets  65. hRTM2exp.3j.x3j T16.expALL.html (hRTM2 html)
Co-constraints for several PHD devices (NBP, SpO2, Glu, Coag) have been added, based on the published PHD and -104xx device specializations. PHD-nibp-spo2-glu-inr.1e.x3g T12.html

Additional observation identifiers and settings
1. IEEE-SA staff has already merged :2004 and a-2015 into a single document.
2. Inclusion of new terms in draft standard is contingent on timely completion.

5. IEEE P11073-10101c [PAR approval in progress]
Existing list of ISO/IEEE :2004 MDC_EVT_ identifiers will be extended to support the IHE PCD Rosetta for Events and Alerts.
Will cover physiologic alerts and essential technical events and alerts
PAR: IEEE P c- PAR Detail_jw1.pdf
Status: PAR submission deferred, strongly consider adding MDC_EVT terms to IEEE P b instead.

6. IEEE P11073-10103a [PAR approved]
Extends IEEE P :2012 Implanted Devices Cardiac
New IDC term codes, extending IEEE P :2012
Considering EGM waveforms.
New terms were presented and discussed at the Heart Rhythm Society (HRS) meeting in San Francisco
See presentation: IDC Nomenclature Status 20-Sep-2016.ppt

7. New Term REFID and Code Assignments
Background for this discussion, motivated by the desirability of assigning numeric codes at the earliest possible time.
Use the NIST RTMMS as the authoritative numeric code validator (and generator) for new terms to guarantee non-overlap between multiple organizations, e.g. IEEE PoCD, IEEE PHD, IHE PCD Rosetta PCHA/Continua, OR.NET and others.
If the assigned Reference ID, Disc, Part::Code is discarded during balloting, it is retired as a “zombie term” and cannot be re-used.
Terms that are assigned codes must have complete definitions, UoMs, enum values and other information when they are submitted as an Excel worksheet, formatted exactly as it would appear in the published standard.
Is this a good idea?
Yes, if we can keep the number of “zombie terms” to a small number (e.g. < 1 to 5% of new terms defined).
No, we could end up with a ‘free-for-all’ if this is uncontrolled without any degree of editorial review and curation.

8. Code and Term Assignment (final)
Code and term assignment process is similar to term assignment flow using the NIST RTMMS four years ago.
Fully defined terms proposed and approved by a recognized working group (e.g. IEEE PoCD, PHD, IHE PCD Rosetta, PCHA/Continua, OR.NET and others) can have numeric codes assigned to them prior to IEEE balloting for deployed in messages. The status of each term (proposed, assigned, approved) would be maintained on the NIST RTMMS.
If the assigned { Reference ID, Disc, Part::Code } is rejected during IEEE balloting, it will be retired as a “zombie term” and the Part::Code shall not deployed in messages nor recycled for use with another term in the future.
