RE: Standardization Feedback for Sub-Committee on Standards
On behalf of the Board of Directors of Health Level Seven International (HL7), we are pleased to offer our
comments on the effectiveness of federal agency participation in the development and implementation of
standards. Our responses are organized according to the RFI’s four broad headings:
•
•
•
•
Perspectives on government’s approach to standards activities
Issues considered during the standards setting process
Adequacy of resources
Process review and improvement metrics
Perspectives on government’s approach to standards activities
HL7 has worked with multiple government agencies over the course of the last two decades. During
2010, a number of these agencies participated as organizational members of HL7, including Agency for
Healthcare Research and Quality, (AHRQ), Centers for Disease Control and Prevention (CDC), Centers
for Medicare & Medicaid Services (CMS), Department of Defense (DoD), Food and Drug Administration
(FDA), the National Cancer Institute (NCI), the National Library of Medicine (NLM), the National Institute
of Standards and Technology (NIST), and the US Department of Veterans Affairs (VA). A number of
state public health agencies also maintain membership within HL7.
HL7 has forged strong and successful partnerships with many federal agencies to develop and bring
needed standards to the marketplace. One of HL7’s earliest collaborations was with the CDC in the early
1990s to develop messages permitting the transmission of immunization records from care providers to
local and state public health agencies and on to CDC immunization registries, queries of these registries
for immunization public health records, and the return of these immunization records to care providers.
These messages are still in widespread use today and CDC continues to maintain and distribute the
current code sets for these messages
The National Committee for Vital and Health Statistics (NCVHS) and CMS worked closely with HL7 and
X12 through the HL7 Attachments Work Group to develop the supplemental information needed to
support healthcare insurance and other e-commerce transactions. Started in 1997, the work group has
created and balloted implementation guides and attachment specifications that use HL7 Version 2.x
messaging and the HL7 Version 3 Clinical Document Architecture (CDA™) standards. These were
incorporated into a notice of proposed rulemaking (NPRM) under HIPAA in 2005, and work continues
today for an update and expected future publication of final rule on transactions to support attachments
for both claims and referral authorization.
In the mid 1990s, HL7 worked with the NLM on a three-year project to develop and apply methods to
ensure that the UMLS Meta-Thesaurus was aligned with the HL7 vocabulary standards. This work was
undertaken to ensure Consolidated Health Informatics (CHI) vocabularies as distributed through NLM’s
UMLS Metathesaurus are usable with HL7 and to develop implementation guide(s) for the use of HL7 to
transmit electronic health record (EHR) data and documents between two systems, independent of
source and destination architectures.

The FDA has been an active participant in, and founding member of, the HL7 Regulated Clinical
Research Information Management Work Group, a joint collaboration between HL7, the FDA and the
Clinical Data Interchange Standards Consortium (CDISC). This group develops standards to improve or
enhance information management during clinical research and regulatory evaluation of the safety,
efficacy and quality of therapeutic products and procedures worldwide. Among other work products, this
group has developed two very successful standards: the Structured Product Labeling (SPL), a document
markup standard approved by HL7 and adopted by FDA as a mechanism for exchanging product
information; and the Biomedical Research Integrated Domain Group (BRIDG) Model, a domain analysis
model representing protocol-driven biomedical/clinical research. The FDA has also worked with HL7 to
develop the Individual Case Safety Report (ICSR) standards for reporting adverse events and product
problems to regulatory agencies, and the Common Product Model for periodic reporting of safety updates
in relation to medicinal products in pre- and post-marketing.
In 2001, at the request of the then DHHS National Health Information Infrastructure (NHII) and now ONC,
the VA partnered with HL7 to fund the creation of an internationally-focused Electronic Health Record
System Functional Model (EHR-S FM). Subsequently, HL7’s EHR Work Group has created an
internationally-focused Personal Health Record System Functional Model (PHR-S FM) and conformance
requirements that provide guidance in the development of functional profiles (which are realm-,
application- or care setting-specific constraints of the EHR-S FM and PHR-S FM).
AHRQ funded and supported HL7’s recent efforts to create a forum for clinicians to bring their needs and
knowledge to HL7 without being burdened by the technical requirements of standards developments. This
effort ultimately resulted in the formation of the Clinical Interoperability Council, an active work group
within HL7 that provides a nexus of communication and bridge to the standards development framework,
organizational processes and forums for the clinical community to define content, flow, and other domain
requirements necessary to the development of robust health data standards. More recently, substantial
HL7 cooperation and collaboration with ONC contractors produced a balloted implementation guide that
met ONC’s requirements for clinical laboratory messaging.
In recent years, the National Cancer Institute (NCI) has collaborated with HL7 to develop the Services
Aware Interoperability Framework (SAIF). SAIF is an architecture framework for achieving interoperability
via HL7’s artifacts including support services, messages, and clinical documents created with HL7’s V3
Clinical Document Architecture (CDA). This architecture framework is in use at the NCI and is being
implemented across HL7.
NIST is also a long-time HL7 member and has made a number of contributions to our standards
development process. While HL7 fully supports accredited processes, we also recognize that there are
other equally good and effective processes. NIST has studied and published a number of findings relative
to the characteristics of good process that result in successful standards adoption and has brought some
of those findings and processes into HL7 without conflicting with our own ANSI-accredited processes.
NIST is well qualified to provide guidance and advice to federal agencies relative to good processes and
characteristics of processes that should be implemented nationally to meet the goals of the American
Recovery and Reinvestment Act of 2009 (ARRA) Title XIII Health Information Technology for Economic
and Clinical Health Act (HITECH Act).
Finally, a number of federal agency employees have also participated in the governance of HL7 by
serving on its Board of Directors. Other federal agency employees serve on HL7’s Advisory Council
and/or Technical Steering Committee (TSC). Both HL7 and the federal agencies have benefitted from
these activities and collaborations and we anticipate continuing to work with these groups in the future.
Issues Considered During the Standards Setting Process
HL7’s intellectual property takes the form of copyrights on its balloted standards and implementation
guides, and various trademarks on its name and key products. Our standards are registered with the US
Copyright Office and are covered under the protections of that agency. As a not-for-profit organization,
HL7 derives its revenues from licensing fees, which are then re-invested to provide services to HL7

members and participants in the form of meetings and meeting support, balloting services, and Internetaccessible products and services. HL7 therefore asserts control of its intellectual property and assumes
that all users, including the US government, will pay appropriate license fees to access and use HL7
intellectual property.
There are a number of apparent discrepancies around federal agency funding of standards, particularly
those that federal agencies have helped develop. HL7 recommends timely resolution and publication of
guidance with respect to these discrepancies. For example, the National Technology Transfer and
Advancement (NTTA) Act of 1995 directs federal agencies to use standards developed by voluntary
consensus bodies. However, HIT guidance from Federal CIO Sept 17, 2010 directs certain federal
agencies to “Incorporate shared Federal standards and terminologies where available, and contribute to
their ongoing development where needed.” Other legislation indicates that a standards development
organization cannot enforce its own copyright against a free distribution of its standard, and USC § 105
indicates that the US government owns the copyright to work completed by contractors hired by a federal
agency. Likewise, there is currently no shared understanding as to how much of American National
Standards Institute (ANSI)-accredited standard the government can use without compensating the SDO
for fair and reasonable IP rights. Such discrepancies create confusion and will continue to hinder
collaboration and successful adoption of needed standards. HL7 requests clarification on the apparent
discrepancy in the law and letters above.
HL7 recognizes that an individual’s health does not respect jurisdictional borders and therefore is
committed to the development and use of international standards. We recommend that the US
government include this criterion in its standards selection process. The FDA already respects this
criterion, with the proposed use of the GS1 standard for unique device identifier being a recent example.
Finally, HL7 agrees wholeheartedly that innovation is crucial to the successful launch of our national
healthcare reform initiative. However, such innovation cannot be so inwardly focused as to overlook the
work and accomplishments of our colleagues in other countries.
Adequacy of Resources
There is ongoing federal support for maintenance and free access to the Systematized Nomenclature of
Medicine – Clinical Terms (SNOMED CT) and Logical Observation Identifiers Names and Codes
(LOINC), two federally mandated vocabulary standards. These represent successful case studies, and
federal support of these standards should continue. Expansion of this approach to encompass other
standards required for national healthcare reform, including Digital Imaging and Communications in
Medicine (DICOM), the National Council of Prescription Drug Programs (NCPDP), HL7, etc., or the
creation of a subscription service to ensure easy access to and understanding of the licensing
requirements, will enable standards organizations to develop the tools and implementation guides crucial
to successful standards adoption. NIST is well qualified to guide and advise the federal agencies in the
development of licensing and/or subscriptions arrangement suitable for this purpose.
While HL7 has enjoyed and benefitted from the participation of federal agency employees, there is an
increasing and continuing need for federal involvement in the accredited standards development process.
Ensuring that federal agencies are involved early in the standards development and that most, if not all,
of the relevant federal agencies are actively engaged would be helpful. As a beneficiary of successful
standards adoption, the federal government should feel compelled to support the infrastructure needed to
develop and maintain standards, particularly those that are mandated. Canada Health Infoway and
Standards Australia are just two of the many examples of standards activities that enjoy country-wide
support as a result of government sponsorship.
A number of changes within HL7 are making our standards more enticing to the communities but
adoption will be hindered without faster development of tools to assist with the implementation of robust
interoperability standards across international environments. The federal government can assist this
effort by assuming some of the licensing or tools development costs.

Process Review and Improvement Metrics
Substantial process improvement can be realized by upfront harmonization rather than retrospective
review. The industry is aware of the good and critical work of IHE, the Standards and Interoperability
Framework initiatives, HL7 and other standards groups, and it is incumbent on the federal government to
help fund the standards lifecycle and the corresponding infrastructure of all of those groups to enable
improvement. Only then can we ensure development and adoption of the interoperability standards that
will be required for the greatest endeavor of all time.
