Paul Schluter, GE Healthcare

2. Topics IEEE Std 11073-10101 and NIST RTMMS Update
IEEE P b – new observation terminology
IEEE P b – events and alerts
IEEE P a – IDC extensions
NIST RTMMS – new terminology process to accelerate MDC numeric code assignments
PHD, PCHA/Continua Terminology in NIST RTMMS

3. IEEE Std 11073-10101a and NIST RTMMS update
NIST RTMMS has been updated with a nomenclature.
Co-constraints (units, enums and sites) for a terms have been uploaded to NIST RTMMS and are now available.
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

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 P11073-10101b [Events and Alerts]
The existing list of ISO/IEEE :2004 MDC_EVT_ identifiers will be extended to support the IHE PCD Rosetta for Events and Alerts and other requests.
These will be included in IEEE P b , based on discussion last year.
Will cover physiologic alerts and essential technical events and alerts (see companion presentation).

6. IEEE P11073-10103a [PAR approved]

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

8. 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, MDPnP, 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 3% 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.

9. Code and Term Assignment Process
 Proposed 0^MDCX terms that have not been approved by a recognized working group, let alone by the larger IEEE community.
 Provisional terms that have been approved by a recognized working group (e.g. IEEE PoCD, PHD, IHE PCD Rosetta, PCHA/Continua, MDPnP, OR.NET and others) may have numeric codes assigned to them prior to IEEE balloting. The status of each term (proposed, provisional, published) will be maintained on the NIST RTMMS.
 Published terms are those that have been balloted, approved and published as an IEEE standard.
Note: If a provisional term is rejected during IEEE balloting, the { Reference ID, Disc, Part::Code } 3-tuple 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 (enforced by NIST test tools). Proposed and provisional terms are subject to change and are not final until published in an IEEE standard.
