CDA (R1)

The Clinical Document Architecture (CDA) is a specification for the exchange of electronic clinical documents. It can contain coded data and narrative and is compatible with the electronic health record and document management systems. CDA is at the core of virtually all standards-based exchange networks in the US and abroad and is adaptable for dictated notes and highly-structured public health and quality reporting.

Clinical documents are the core of a patient's lifetime health record. HL7’s CDA standard provides an exchange model for clinical documents such as discharge summaries and progress notes. A consistent approach to electronic clinical documents means that critical information contained in the documents can be used independently of the application on which it was produced. For example, CDA documents can be displayed using XML-aware Web browsers or wireless applications on mobile devices.

CCD

HL7 and ASTM International created the Continuity of Care Document (CCD) to integrate two complementary healthcare data specifications ASTM’s Continuity of Care Record (CCR) and HL7’s Clinical Document Architecture (CDA). The CCD is endorsed by the Healthcare Information Technology Standards Panel (HITSP) as the harmonized format for the exchange of clinical information, including patient demographics, medications and allergies.

The HL7/ASTM Continuity of Care Document (CCD) is an implementation guide for sharing Continuity of Care Record (CCR) patient summary data using the HL7 Clinical Document Architecture (CDA). CCD establishes a rich set of templates representing the typical sections of a summary record and expresses these templates as constraints on CDA. These same templates—for vital signs, family history, plan of care, and so on—can then be reused in other CDA document types, establishing interoperability across a wide range of clinical use cases. The CCD is the basis for interoperability in the US Health Information Technology Standards Panel (HITSP) and Integrating the Healthcare Enterprise (IHE) use cases.

SPL

Structured Product Labeling (SPL) defines the content of human prescription drug labeling in an XML format. This format is defined within the SPL schema and is displayed in a web browser using the SPL stylesheet. It is approved by Health Level Seven (HL7) and has been adopted by FDA as a mechanism for exchanging medication information. (from Wikipedia)

SPL documents contain both the content of labeling (all text, tables and figures) for a product along with additional machine readable information (drug listing data elements). Drug listing data elements include information about the product (product and generic names, ingredients, ingredient strengths, dosage forms, routes of administration, appearance, DEA schedule) and the packaging (package quantity and type).

The benefits that accrue to all stakeholders in the drug regulatory process by adoption of Structured Product Labeling (SPL) make the business case for implementation of SPL overwhelming. The benefits of SPL derive from use of standard, universally adopted information standards such as XML, from the specific aspects of the SPL model for describing prescription drug content, and from adoption of an open standard for SPL.

EHR FM

The healthcare industry will reap tremendous benefits by adopting a common standard for electronic health record systems (EHR-S). The HL7 EHR-S Functional Model outlines important features and functions that should be contained in an EHR system. Through the creation of functional profiles, this model provides a standard description and common understanding of functions for healthcare settings. To date, HL7 has developed or is developing profiles for areas such as child health, emergency care, long term care, behavioral health and vital statistic reporting. The EHR-S Functional Model is also in the final stages of vetting as an international standard through ISO.

Personal Health Record System Functional Model (PHR-S FM)

The PHR-S FM defines the set of functions for Personal Health Record (PHR) systems and offers guidelines that facilitate health information exchange among different PHR systems and between PHR and Electronic Health Record systems. The PHR-S FM is was published as a Draft Standard for Trial Use (DSTU) in December 2008. During the period of trial use, consumers can begin requesting standards-based functionality when they select PHR systems for their use, vendors can begin incorporating the model’s requirements into their products and organizations that certify PHR systems can begin using the model’s conformance criteria for certification development and testing purposes. Groups such as the Certification Commission for Healthcare Information Technology (CCHIT) and the Centers for Medicare and Medicaid Services have already begun using components of the PHR-S FM

SAEAF

The HL7 SOA-Aware Enterprise Architecture provides a framework for specification of standardized services that can be used by the HL7 community. It identifies artifacts and a constraint pattern that provides traceability from requirements. These specifications align with different levels of conformance that aid HL7 consumers in adopting standards in different contexts, and supports specific integration patterns between collaborators as they seek to achieve computable semantic interoperability.

The ArB Jump Start project was convened in the spirit of the “Left Side of the RIM” meetings some years ago. That is, they were an attempt to simplify and clarify the problem of how services will be created in HL7, how services serve a strategic vision, and then to bring the results of those discussions back to the community in an open and transparent manner. The ArB, through its membership and in conjunction with the organizations that were represented at the meetings, has defined portions of an enterprise architecture that is services-aware, that can aid HL7 in crafting a strategic vision that supports services, and (somewhat surprisingly) seems to provide a number of extension points that allows the various artifacts from HL7 to be aligned. The members of the ArB termed this the “unified field theory.” While this was neither the goal nor the focus of the Jump Start Sessions, the ArB took this finding as an indicator that we are fundamentally on the right track.

The HL7 SOA-Aware Enterprise Architecture provides a framework for specification of standardized services that can be used by the HL7 community. It identifies artifacts and a constraint pattern that provides traceability from requirements. These specifications align with different levels of conformance that aid HL7 consumers in adopting standards in different contexts, and supports specific integration patterns between collaborators as they seek to achieve computable semantic interoperability. The HL7 SOA EA builds on the successes of the Healthcare Service Specification Project, taking many of its artifacts and its initial services as starting points. The lessons learned through the HSSP process as well as through the implementation of HSSP artifacts has provided a consistent touchstone for this effort.

The Enterprise Architecture provides things that HL7 supporters need to achieve working interoperability in any given context. It uses the RM-ODP standard as a framework within which to create and define artifacts and specifications. RM-ODP provides a 4 dimensional approach to specification via conformance assertions. This approach allows for complete system specifications to be built from the business, informational, computational, and engineering viewpoints, and for the technical realization of these things to verify and validate the conformance assertions arising from these viewpoints. The things that the EA provides are not limited to “services”, though SOA provides some focus and placeholders for talking about functional semantics in a way that has traditionally been difficult to breach.

The ArB feels that the combination of HL7, SOA, EA, RM-ODP, and MDA allows not only for a successful framework for the creation of services, but also most other HL7 artifacts. This “unified field theory” was not a goal of these ArB Jump Start sessions – on the contrary, the focus at first was very much on services to the exclusion of documents and messages. But in the process of creating a structure for specifying services, the ArB feels that they have provided a means of contextualizing other HL7 work, mixing it with a logical dynamic model, contract-based integration, functional specification, requirements traceability, and explicit expressions of policy and governance. Additionally, some clarity has been achieved in establishing the foundation of a governance model within HL7 as well as answering some existing questions around what it means to conform to HL7.

The ArB feels like it has provided a potent framework for specification of HL7 standards, including documents, services, and messages. This framework supports an explicit conformance model, and allows for extension of organizational governance models to incorporate these specifications. It has specified a meta-model for dynamic frameworks that aligns with two industry standards (SOA Pro and WS-CDL). It aligns with the recent work within several national organizations (DoD, Canada Infoway, NCI caBIG), and seems to align with the recent work from B.G.M.E. Blobel.

Claims Attachments

In response to the federal mandate under HIPAA, HL7 and ASCX12 collaborated for a number of years to develop standards for claims attachments. This joint development effort has resulted in standards for attachments to healthcare claims, and pre-certification / pre-authorization transactions. HL7 attachments standards are based on the Clinical Document Architecture (CDA) and have been proposed by the Department of Health and Human Services (HHS) as the standard for claims attachments under HIPAA. In the HHS proposal, six attachment types developed by HL7 have been put forward for adoption: clinical reports; rehabilitation services; laboratory results; medications; ambulance services; and emergency department.

Clinical Genomics Pedigree Topic

The HL7 Clinical Genomics Pedigree Topic includes the Family History Model describing a patient’s pedigree with genomic data. It has the ability to transmit complete family history information for clinical decision support. This model is ANSI-approved and is the HITSP-accepted standard. This standard allows EHR/PHR interoperability, and is in use by the Surgeon General in his family history collection website: My Family Health Portrait. It is also in the process of becoming of an international standard through ISO.

Version 2 Messaging Standard

The Version 2 Messaging Standard is one of the most widely implemented standards for healthcare information in the world. First released in October 1987 as An Application Protocol for Electronic Data Exchange in Healthcare Environments, Version 2 is a messaging standard that allows the exchange of clinical data between systems. It is designed to support a central patient care system as well as a more distributed environment where data resides in departmental systems. Version 2.6, representing the latest update to the Version 2 Standard, was published in January 2008. Version 2.7 is in the final stages of balloting and is expected to be released later this year.
