Agenda Items

 * 1) Complete review of policy variance differences.
 * 2) Review Kate Hamilton and Rob Snelick’s performance constraint proposal.
 * 3) Begin message structure variance analysis.

Meeting Notes
Within policy variance differences, the team discussed the Use of Identifiers. There were three choices of identifiers:
 * 1) Non-Unique Order Number and Universal Service Identifier are necessary to uniquely identify a individual test being ordered, and the Universal Service Identifier
 * 2) Unique Order Number alone is sufficient to uniquely identify an individual test being ordered, while the Universal Service Identifier only comes across to indicate the test
 * 3) Transition to Unique Order Numbers at a later stage

Though the long term goal is to use unique order numbers, the group created a third choice where stage 2 allows both options one and two, unique order numbers and non-unique order numbers while a later stage transitions to only unique order code numbers. There is an interoperability concern that most LIS systems currently do not support a unique order number in the ambulatory space. The implementation time frame for this should be pinned to the meaningful use stage. The group identified a need to identify profiles that tie an organization to a type of order number. The group agreed with no changes or discussion for Patient Identifier, Result Identification, and Use of Escape Sequence. For OIDs, the group identified a challenge that there is no method to determine that a person has registered or used an OID. The challenge is twofold:
 * 1) Technology: There are issues that pertain to the specific technology of OIDs
 * 2) Policy Issue: These issues refer to the policy and exist irrespective of the OID technology

For Conformance Constraints, the group discussed the supporting documents: Conformance Verbs Document and Conformance Usage Document.
 * Conformance verbs document defines common conference verbs, such as Shall, Should, Must, etc.
 * Conformance usage document contains two changes from the previous 2.7 version: it removes the conformance verb Ignore and clarifies the meaning of rules for receiving applications by having two table separating implementation and operational requirements

The group discussed the message structure and decided to review the data elements created by the use case group to validate the data elements for completeness, create a list of segments that data elements are in, and compare data elements to message structure.

Moving forward, since the Use Case team will no longer hold meetings on Thursdays, we will add an Implementation Guide meeting on 3pm, Thursday. Due to the HL7 conference, there will be no IG Analysis meeting next week. Additionally, the group decided to allow the CIM/Vocab WG to take the lead on UCUM and share their input during the LRI Harmonization meeting.
