1 IEEE GC Montreal IEEE Nomenclature IEEE GC at HL7, Montreal, Quebec Tuesday Q2 – May 10, 2016 Paul Schluter, GE Healthcare

2 IEEE GC Montreal Topics IEEE Std and NIST RTMMS Update IEEE P b – new terminology (PAR approved) IEEE P c – events and alerts (PAR pending) IEEE P a – IDC extensions (PAR approved) NIST RTMMS – accelerate numeric code assignments PHD Terminology in NIST RTMMS (with Malcolm Clarke)

3 IEEE GC Montreal IEEE Std a and NIST RTMMS update Approved by IEEE-SA Standards Board on December 5, 2015 Published on December 9 th and uploaded to NIST RTMMS 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 will be available shortly, pending final review and verification. The new second-generation harmonized Rosetta, hRTM2, will combine the ‘old’ and ‘new’ 10101a terms and co-constraints, and use aECG lead offsets  65. XSL Output.x2c T13.html (hRTM2 html) XSL Output.x1e T11.uom.html (UOM comparison with NIST RTMMS) XSL Output.x2c T13.html XSL Output.x1e T11.uom.html Co-constraints for several PHD devices will also be included, based on published PHD and -104xx specializations.

4 IEEE GC Montreal IEEE P b [PAR approved] Extends ISO/IEEE Std :2004 and a-2015: Infusion pumps and infusion events (IHE PCD PIV and IPEC) Ventilator mode, high-frequency ventilation, annotations NMT Neuromuscular transmission (level of neuromuscular block) NMT.ParameterList.4a T12.docx (use ‘named’ data items; enumerated values next) NMT.ParameterList.4a T12.docx Finalize the WCM waveform attributes (or just use aECG) IHE PCD Device Management Control (DMC) IHE PCD Real-Time Location Services (LS) Generalized Signal Quality Index Dialysis Surgical and OR devices (by OR.NET at Additional observation identifiers and settings Note: Inclusion of content in draft standard is contingent on timely completion.

5 IEEE GC Montreal IEEE P c [PAR to be approved] 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.pdfIEEE P c- PAR Detail_jw1.pdf Action required: IEEE leadership approval to move forward.

6 IEEE GC Montreal IEEE P a [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 last weekend. See presentation: IDC_nomenclature_status_May2016_v03.pdfIDC_nomenclature_status_May2016_v03.pdf

7 IEEE GC Montreal New Term REFID and Code Assignments Background for this discussion, motivated by the desirability of having numeric code assignments at the earliest possible time. Use NIST RTMMS as the authoritative numeric code generator for new terms to guarantee non-overlap between multiple organizations, e.g. IEEE 11073, IHE PCD DEC, PCHA. If the proposed Reference ID, Disc, Part::Code is discarded during balloting, it is retired as a “zombie term” and cannot be re-used. Is this a good idea? Yes, if we can keep the number of “zombie terms” to a small number (< 5 – 10% 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.
