2 2 HL7 DEV SIG and IEEE 11073 GC 2015-01-22 IEEE P11073-10101a Status IEEE P11073-10101a/D5 recirculation ballot currently underway after six IHE PCD ACM numeric codes were corrected. IEEE-SA RevCom review now rescheduled for December 2015, with anticipated approval on December 5 th and publication possibly as early as December 9 th. Plan to facilitate upload of new terms to NIST RTMMS at the earliest possible date, with wider disclosure when permitted by IEEE-SA (hopefully on or around December 10 th ). Key question: Will this be early enough to allow testing with the NIST RTMMS, NIST test tools and IHE NA Connectathon during January 25-29, 2016?

3 3 HL7 DEV SIG and IEEE 11073 GC 2015-01-22 IEEE P11073-10101a transfer to RTMMS IEEE Std 11073-10101a Annex A and Annex C as XML for IEEE distribution (mimics tables in standard) For RTMMS, include ‘Disc’ in term tables also used to create refid[disc]code 3-tuples [MMM] Statistical Discriminators {2 bits} dOffsetdSuffixdDescription 0 {base measurement} or not specified 1_MAX maximum value observed over an interval 2_MIN minimum value observed over an interval 3_MEAN mean value observed over an interval Reference IDDiscPart::Code CF_CODE1 0 MDC_SAT_O2_DELIV_INDEX MMM2::19596150668 MDC_PRESS_BLD_VEN_FEMO RAL SDM2::19604150676 MDC_PRESS_BLD_ART_BRACH IAL SDM2::19608150680 MDC_TTHOR_HEART_RATE RCE2::18482149554

5 5 HL7 DEV SIG and IEEE 11073 GC 2015-01-22 Disposition of -10101a and hRTM terms The ‘harmonized’ Rosetta (hRTM) terms contains existing terms, terms that require a numeric code, new terms and obsolete and deprecated terms. Their disposition will be documented.

6 6 HL7 DEV SIG and IEEE 11073 GC 2015-01-22 Term Co-Management Issues with PHD Root cause is lack of a single authoritative repository for both PoCD and PHD terms PoCD uses RTMMS, spreadsheets and MS-Word (in draft standard) PHD uses MS-Word, #defines and spreadsheet maintained by co- chairs Difficult to keep synchronized! Six ACM attribute code conflicts with existing PHD caused delay from October to December RevCom; timing is critical for IHE Connectathon! NIST RTMMS would be perfect choice for PoCD and PHD to use Single numeric code generator and repository to guarantee non- overlap Preliminary agreement by PHD co-chairs to use RTMMS (Paul facilitates) Update methods Method 1: Standard RTTMS term entry after initial bulk upload (preferred). Method 2: For an interim period, periodic bulk uploads with term conflict detection with terms already in RTMMS (aligned with current PHD term workflow).

7 7 HL7 DEV SIG and IEEE 11073 GC 2015-01-22 PHD REFIDs and codes alone are insufficient Phase 1: Need other Rosetta co-constraints: units, enumerations, measurement sites and other information: Essential: Reference ID, Disc, Part::Code [CF_CODE10 calculated] also used to create refid[disc]code 3-tuples Source: specifies term source, e.g. 11073-10424-2014-Cor1-D1 Co-constraints: units, enums, sites The Disc and Source attributes would be added to the existing NIST RTMMS as additional columns. Phase 2: PHD device specializations MDC_DEV_SPEC_PROFILE_* and containment/content models would be captured separately, as a computable representation based on Continua WAN Annex J (differences between WAN and PHD would be noted).

8 8 HL7 DEV SIG and IEEE 11073 GC 2015-01-22 Making things easier... Confirmed that REFIDs have unambiguous mappings to numeric codes (only four exceptions found) facilitating documentation using only Reference IDs. REFIDs are only associated with a single numeric code (by design) whereas a numeric code may have multiple ‘REFID-synonyms’. Allows codes to be filled on an ‘as needed’ basis in documentation. The NIST RTMMS excellently supports REFIDs, codes, units, enumerations, and measurement sites, facilitating transfer of PHD information into RTMMS. This will help significantly align PoCD and PHD efforts. As noted previously, Continua WAN ‘Annex J’ and later have containment tables for many PHD devices as sent over the Continua WAN (which is based on IHE PCD DEC).
