Meeting Notes

 * Implementation Guides Analysis Matrix Working Document**

1. Bob Yencha identified several follow up items from last week's call:
 * The PH (Public Health) guide had CWE listed twice: CWE outside of OBX5 and the use of CWE specifically for OBX5.
 * The PH guide contained components that were not found in HL2.5.7 (yellow rows).
 * Within the document, dashes " - " in columns represents that no information was found in the guide for that particular data type.
 * The column heading was changed to ALR for LRI R1.

2. IG Analysis:
 * CNN (Composite ID Number and Name Simplified): Bob Yencha put this section in; WG to discuss this in subsequent meetings.
 * CWE and CWE OBX 5: All components are optional; Highlight OBX-5 to revisit
 * DR, DT, DTM, ED, EI, RP, SN, TM: There are no inconsistencies between base guides; copy usage to be consistent.
 * EIP: Placer Assigned Identifier and Filler Assigned Identifier; Assign " * " under usage to reference specific usage in OBR-29 and SPM-2.
 * NM: Leave as R.


 * OIDS Discussion - Global Unique Identifiers**

1. Value of Global Unique Identifiers:
 * Example: Receivers of results from multiple lab systems that use similar identifiers must differentiate that results coming from one lab is different than another.
 * Globally Unique Identifiers ensures that result IDs are unique across multiple systems.
 * CMS-assigned identifiers do not solve this issue, but OIDS can.

2. Assigning Global Unique Identifiers:
 * Prefix + identifier
 * OIDs

3. OIDs Assigning Authorities: There are several assignign authorities for OIDs though each OID assigned is unique. In the case of multiple assigning authorities, need to determine: who is assigning, when is that happening, what circumstances, and when can be used?

4. IG Proposed Recommendation:
 * Recommend that global identification is the target and that OIDS are the desired end state.
 * Have different profiles:
 * Globally identified profile for organizations that are ready; OIDs are required.
 * Non-Global profile for organizations who are not prepared to use OIDs; OIDs are optional.
 * Value: Allow two alternatives to accommodate current state and to prepare organizations for OIDs requirement.
 * Recommend pilot to drive implementation. This is both a Sender and Receiver Requirement.
 * Start next meeting, 7/5, with a poll on the proposed recommendation.
