ONC Standards and Interoperability Framework

S&I SimplificationProposed Path

November 8, 2011

Alignment View

Awareness at Kickoff

• Immediate “injection” at initiative kickoff– Go over the cross-initiative view and highlight tools to

support the initiative

• Ongoing support through S&I Simplification, CIM and Standards Inventory as we move from requirements – data- standards harmonization – working code- pilots

Expanded Charter

The cross-initiative view would cover the following:

• Actors• Systems• Metrics• Data Element Names and Definitions• Data Element Sets• Standards Inventory

S&I Simplification Objectives

• A cross-initiative workgroup open to all initiative members, focused on creating a high-level view of reusable constructs for potential use by each S&I initiative and to work to make recommendations to all WGs and S&I Framework teams.

• To identify a core set of constructs broadly applicable to each initiative and to ensure reuse for better overall understanding of outputs produced by the S&I Framework

Actors

• Common set of actors, roles, and proposed actions for each actor that can be reused across all initiatives

• GOAL: Use of common actors and roles for each actor in use case, diagramming, and pilots for better understanding

Systems

• Common set of system names and definitions that can be reused across all initiatives

• Goal: Use of common systems in use case, diagramming, and pilots for better understanding

Metrics

• Give each initiative a base set of metrics to work off of that can be extended as needed– Start with the TOC and LRI success metrics– Base metrics that apply to all– Initiative specific metrics

• Goal: Better visibility to provide pilots with specific metrics they

Data Element Names and Definitions

• An index of all the data elements defined to date in the S&I Framework initiatives

• Goal: Ensure that all data elements get documented within the CIM (as a data dictionary). Ensure reuse and common data definitions to improve understanding

Data Element Sets (DES)

• Create reusable data element sets that serve as a cross walk between the use case and the CIM

• Goal: Needs to be defined

Data Element Names

• An index of all the data elements defined to date in the S&I Framework initiatives

• GOAL: Common use of data elements and definitions across all the initiatives

• Definitions can be extended but a set of “naming rules” should be used

• Tied directly to the CIM – focus on clinical/business name

Important Assumptions

• Informative, not prescriptive– S&I Simplification Workgroup does not “order” or

“control”, they advise and inform– Initiative may reuse what they like

• Requires S&I Simplification to “do the work”– Should participate in all S&I Framework activities
