2. www.ushik.org 2 What is national health information? National health information is information that either is national in coverage or has national relevance and relates to: the health of the population the determinants of the population’s health, including external factors and those internal to individuals health programs or health services, covering information on the nature of the services provided and their management, resourcing, accessibility, use and effectiveness the relationships among these elements

3. www.ushik.org 3 Why is it needed? To enable informed decision making To guide consumers’ decisions To provide needed information about the needs of the populations, the effectiveness of their interventions and for whom, and the acceptability of these interventions To compare the effectiveness and efficiency of healthcare To make decisions in health industry and governments need information about how to provide services equitably, efficiently and effectively

5. www.ushik.org 5 Introduction USHIK Goals: To provide and maintain a metadata registry of health information data element definitions, values, and information models which will enable browsing, comparison, synchronization, and harmonization within a uniform query and interface environment. Build, populate, demonstrate, and make available for general use a data registry to assist in cataloging and harmonizing data elements across multiple organizations.

Where are data elements defined? Codes can be downloaded for use in applications. A data registry is a place to keep facts about characteristics of data that are necessary to clearly describe, inventory, analyze, and classify data. A data registry supports data sharing with cross-system and cross-organization descriptions of common units of data. A data registry assists users of shared data to have a common understanding of a unit of data’s meaning, representation, and identification.

19. www.ushik.org 19 Initiatives HIPAA – The Health Insurance Portability and Accountability Act Title II of HIPAA requires the establishment of national standards for electronic health care transactions and national identifiers for providers, health insurance plans, and employers. CHI – Consolidated Health Informatics Adopts a portfolio of existing health information interoperability standards (health vocabulary and messaging) enabling all agencies in the federal health enterprise to “speak the same language” based on common enterprise-wide business and information technology architectures. HITSP - Healthcare Information Technology Standards Panel - The mission is to serve as a cooperative partnership between the public and private sectors for the purpose of achieving a widely accepted and useful set of standards specifically to enable and support widespread interoperability among healthcare software applications, as they will interact in a local, regional and national health information network for the United States.

20. www.ushik.org 20 Value Government programs can use this tool: –To compare their data elements with those in USHIK for harmonization –To develop data elements for new programs based on those in USHIK, and –To stay current with standards developing organizations (SDO’s) changes in their standards –To aid in harmonization among States & Territories Certification authorities can use this tool: –To verify that data elements in a given EHR system are interoperable with the data elements in: A specific interoperability criterion, A specified data standard, or Another specific system

21. www.ushik.org 21 USHIK Strategic Federal & Business Use Contributes to President’s eGov initiative support (Consolidated Health Informatics initiative-CHI) Value to Health Information Technology Standards Panel (HITSP) Using USHIK in each HITSP lifecycle Phase 1: Gap Analysis & Standards Selection Phase 2: Standard Specificity Phase 3: Interoperability Specifications Clinger-Cohen Act mandates facilitation of eGovernment – Citizen business relationships USHIK is a focal point to publish federally designated health standards, data elements and definitions (metadata) online

22. www.ushik.org 22 USHIK use by HITSP Technical Committees To support a mapping analysis –E.g., do two standards have the same demographic variables and representations To support the gap analysis after the standards have been selected by the Technical Committee –For comparing the required data elements of the use case with what the chosen standard contains To objectify the standards selection process by providing a neutral, identical presentation of the candidate standards To support giving feedback to the SDOs for improving a standard to fit the needs of the use case –Ask the SDO if some specific changes are possible to improve interoperability (cross-organizational, cross-system data sharing) Publish choices and document for long-term maintenance www.ushik.org

23. 23 Viewpoint for the implementation of HITSP and ANSI Technical Committee use case Focal point to examine Technical Committee standards, data model relationships Uniform environment to compare, synchronize, harmonize standards overlaps – gaps

24. www.ushik.org 24 How AHRQ and CMS Support HITSP By providing a USHIK health information specialist assigned to the Technical Committee for one use case –To learn the standards selection process of the HITSP TC –To provide expertise at using USHIK to answer TC questions –To provide expertise at using USHIK to present comparisons across standards requested by the TC –To display choices made by the TC in a standard metadata registry format

25. www.ushik.org 25 How AHRQ and CMS Support HITSP (cont.) By providing a potential method for comparing the standards choices made by a HITSP TC with those choices made by another HITSP TC By providing an opportunity for helping HITSP to streamline the processes of standards screening, selection, and gap analysis
