HITSP Mission and Role
Mission:
To harmonize relevant
standards in the health
care industry to enable
and advance
interoperability
The standards
harmonization process is
an open, inclusive,
collaborative, use case
driven process
www.hitsp.org
1. Identify a pool of standards for a
general breakthrough area
2. Identify gaps and overlaps for a
specific context
3. Make recommendations for resolution
of gaps and overlaps
4. Develop interoperability specifications
for using the selected standard for a
specific context
5. Test the instruction for using the
standard

Technical Standards Not Policy
HITSP focuses on technical standards and NOT on policy definition
A standard specifies a well defined approach that supports a business
process and . . .
– has been agreed upon by a group of experts
– has been publicly vetted
– provides rules, guidelines, or characteristics
– helps to ensure that materials, products, processes and services are fit for
their intended purpose
– is available in an accessible format
– is subject to ongoing review and revision process
Harmonization is required when a proliferation of standards prevents
progress rather than enables it

HITSP Harmonization Framework
HITSP decomposes the Use Case requirements into
scenario(s) and then into transactions providing context:
technical actors, actions and content
It may create or reuse a transaction or a grouping of
transactions (transaction package) based on commonality at
this level
Transactions are logical groupings of actions that are
decomposed into components, which are groupings of base
standards that work together, such as message and terminology
Evaluation of Standards Harmonization Process for HIT
22
HITSP Harmonization Framework (continued)
Each HITSP construct, i.e., transaction package, transaction or
component, may constrain the construct or standard below it.
Constraints are specified in each construct as appropriate,
additional constraints may be imposed by higher level
constructs to control optionality in a specific scenario
Transaction packages, transactions and components all are
potential candidates for reuse if a new set of requirements and
context are successful fulfilled by the existing construct
While reuse is a HITSP goal, it is established in the context of a
Use Case and its functional/interoperability requirements
HITSP constructs are version controlled and uniquely identified

Per HITSP definition the term
“standard” refers, but is not limited
to:
–Specifications
–Implementation Guides
–Code Sets
–Terminologies
–Integration Profiles
27
Design and Standards Selection
Once requirements have been defined, HITSP scopes the set of
constructs to address them
HITSP designs the constructs based on Technical Actors and
Transactions
– New constructs
– Existing constructs to be reused
HITSP identifies the pool of candidate standards
HITSP evaluates the candidate standards against Tier 1 and Tier 2
criteria to define the selected standards
The Requirements, Design, and Standards Selection (RDSS)
document is published for a four week comment period
Evaluation of Standards Harmonization Process for HIT
28
Tier 1 Standards Readiness Criteria
The standards required to
support each major Use
Case event were organized
within an agreed upon
standards taxonomy
The standards selected for
inclusion in the pool were
examined using ‘HITSP
approved’ Tier 1 and Tier 2
Harmonization Readiness
Criteria
Evaluation of Standards Harmonization Process for HIT
29
Tier 2 Standards Readiness Criteria
Suitability
– The standard is named at a proper level of specificity and meets technical
and business criteria of use case
Compatibility
– The standard shares common context, information exchange structures,
content or data elements, security and processes with other HITSP
harmonized standards or adopted frameworks as appropriate
Preferred Standards Characteristics
– Approved standards, widely used, readily available, technology neutral,
supporting uniformity, demonstrating flexibility and international usage are
preferred
Standards Development Organization and Process
– Meet selected criteria including balance, transparency, developer due
process, stewardship and others
Total Costs and Ease of Implementation
– Deferred to future work
Evaluation of Standards Harmonization Process for HIT
30
Interoperability Specification Development,
Inspection Testing and Public Comment
Once the RDSS is published, HITSP begins to define and document
the Interoperability Specification constructs
Comments on the RDSS are feed into the Interoperability
Specification development process – the RDSS is not republished
The Interoperability Specification constructs are published for a 4week period of public comment and inspection testing
Inspection Testing is a focused desktop review of the constructs
– Inspection Testers are recruited from the HITSP membership and other
interested stakeholders
– Inspection Testers are given a set of specific criteria to be used to evaluate
the Interoperability Specification construct
Evaluation of Standards Harmonization Process for HIT
31
Inspection Testing Objectives
Objective
To validate that the IS….
Process
Meets Use Case
Requirements
 Validate that the IS when implemented will meet the specific
requirements as defined in the use case and contains
accurate references and data
Is Technically Valid
 Check the specification to determine the existence of the
following:
― Ambiguities/ lack of specificity
― Inconsistencies
― Gaps and overlaps
― Testability
― Completeness
― Internal consistency
― Ability to implement
Evaluation of Standards Harmonization Process for HIT
32
Resolution and Publication
The public comments and the results of the Inspection Testing are
reviewed and dispositioned by the HITSP Technical Committees
– Content changes are: Accepted, Accepted with modification, Rejected
(non-persuasive)
– Process-related changes are referred to Process Review Committee
– Project-related changes are referred to the Project Team
The Interoperability Specification constructs are republished and
presented to the Panel for approval
Upon approval by the Panel, the Interoperability Specifications are
advanced to AHIC, ultimately to be accepted and then recognized
(one year later) by the HHS Secretary
Evaluation of Standards Harmonization Process for HIT
33
Implementation Testing
Once the specifications are released HITSP enlists partners to:
– develop test plans, data and suites to test the implementation
– support a program for progressive testing, feedback and deployment of
implementations
Feedback from test implementers is used by the Technical Committees
to revise and republish the Interoperability Specifications
The HITSP implementation support and testing process does NOT
involve any kind of determination of a products “conformance”
HITSP is currently working with NIST, CCHIT, and ONC to define an
overall integrated interoperability testing strategy
– As a first step, HITSP has worked with NIST to establish an Implementation
Testing and Support website, which provides links to existing test resources

Evaluation of Standards Harmonization Process for HIT
35
Maintenance Process
HITSP documents are maintained through a structured release and
publication process; with on-going “major” or “minor” releases
Major - Any change that introduces a requirement where a modification
to an implementation MUST occur in order to remain conformant to the
Interoperability Specification, or a component thereof, is to be
considered a major change
– Major releases go through inspection testing, public comment, and Panel
approval
– Major releases are versioned as (1.0, 2.0, 3.0 etc)
Minor - Any change that loosens restrictions, clarifies use or intent but
does not require any action for an implementation to remain
conformant is considered a minor change
– Minor releases are issued by consensus at the Technical Committee Level
– Minor releases are versioned as 2.1, 2.2, 2.3, etc

Use of HITSP’s Interoperability Specifications
 A HITSP IS addresses the communication of health information among a
number of Business Actors within the context of a specific Use Case.
 There are two dimensions to the use/implementation of a HITSP IS by a set
of “real world systems”. Each system may chose to support:
