2. 2008 initiated H-SOA-RA Healthcare SOA Reference Architecture
This Reference Architecture is built on the HL7 EHR System Functional Model (EHR-S FM), HITSP Interoperability specifications/Capabilities and OMG SOA layers. The objective of the H-SOA-RA is to assure semantic interoperability at the Service Level and consistency within and among systems’ architectural specifications, resulting in aligned, interoperable and agile enterprise architectures and their system components.

Re: Focal Classes:
 The issue is less the idea of a focal class than a business focal class.
The difference is that when you model the service, you are generally modeling a service that will express the state changes of a business.
For example, via analysis, you would find the states of a business focal class (canceled, new, active, signed, finalized in lab orders for
example) and the trigger events that would correspond to state changes ("a lab is ordered", "a lab is canceled", "a lab specimen is corrupted", and so on).
 You could say that a "patient" is a focal class, but a patient ID service generally doesn't express operations to modify the state of that "object". Rather, a patientID service would generally encompass operations that would express information about the class (reconcileID or lookUpID, eg) rather than tying the service functional components to changes in the state of that class.
 It is not a subtle distinction - most clinical domains are focused on a focal class (an order, an encounter, an appointment, a schedule, a lab).
A business service is focused with exposing that class to the enterprise.
 Infrastructure services (or the subset information services) are generally function calls or based on exposing sets of information. The functional profiles of the service are generally not focused on the state of the underlying information or in the trigger events that modify the state of that information. They tend to be focused along different lines - typically along the lines of an information profile (a RIM-based patient class, eg, or a CDA-based CCD).
The focal class is explicit in a business service, generally implicit in other services. 4 4

7. 2009 initiated EHR-SD RM EHR System Design Reference Model
This project matures and integrates the April 2008 Healthcare Services Oriented Reference Architecture (H-SOA-RA) into an EHR System Design Reference Model (EHR-SD RM), using the HL7 SOA-Aware Enterprise Architecture Framework (SAIF), HITSP interoperability specifications, EHR System Functional Model (EHR-S FM) and ARRA artifacts. Emphasis is placed on maintaining HITSP, ARRA, NHIN and CCHIT conformance by maintaining EHR-S FM traceability. Mapping and analysis of the HL7 product portfolio against the EHR-S FM is used to integrate the reference architecture with HL7 product lines and initially mature the resulting model as a technical white papers, then an informative reference model and finally a standard reference model. EHR SD RM info:

8. EHR-SD RM Project Description and Plan
PROJECT DESCRIPTION: HL7 EHR System Design Reference Model (EHR SD RM) This project will mature the April 2008 Healthcare Services Oriented Reference Architecture (H-SOA-RA) version 1.0 into H-SOA-RA Version 2.0, for HL7 Architecture Review Board (ArB) consideration, and then integrate it into an EHR System Design Reference Model (EHR-SD RM), using the HL7 SOA-Aware Enterprise Architecture Framework (SAIF), HITSP Multi-Enterprise Architecture of Networked Services Standards (MEANS), EHR System Functional Model (EHR-S FM). Emphasis will be placed on maintaining AHIC, HITSP, NHIN and CCHIT conformance by maintaining Information Exchange Requirements (IERs) and Data Requirements (DRs) traceability. Mapping and analysis of the HL7 product portfolio against the EHR-S FM will be used to integrate the reference architecture with HL7 product lines and initially mature the resulting model as a technical white papers, then an informative reference model and finally a standard reference model. An HSSP based prototype case study architectural specification will be built to validate the effort.

10. HITSP Constructs
A HITSP Interoperability Specification (IS) defines a business context, supports a business workflow, constrains and orchestrates underlying constructs.
A HITSP Capability (CAP) is a specification that assembles HITSP constructs to fulfill a business need for information exchanges. To use a Capability, an Interoperability Specification or an implementation conformance statement must assign Systems to one or more Capability System Roles and identify how the Capability Options are to be addressed. The use of a Capability shall:
for each assigned Capability System Role, the responsibilities of the assigned System Role must be supported, including all interfaces specified by the underlying HITSP constructs according to the conditions specified for the assigned System Role.
If a Capability option is selected, the implementation must conform to the Capability’s specifications for that option.
A HITSP Service Collaboration (SC) binds communications infrastructure, security and privacy constructs together.
A HITSP Transaction Package (TP), Transaction (T), Component (C) is where standards-based Interface Design Specifications are specified and conformance requirements are defined.

11. Constructing a Future State EHR Reference Architecture
OBJECTIVE: A system agnostic Future State EHR Business Architecture (BA) specified with a lexicon, based upon HITSP’s data architecture, HL7’s System Functional Model (EHR-S FM) and HL7’s Reference Information Model (RIM).
A Health IT EHR BA can be modeled as clinical stakeholder requirements and their workflow-orchestration of
HL7 RIM compliant HITSP data modules manipulated by
HL7 EHR-S FM functions.
NIEM Information Exchange Package Documents
An EHR Information Model, for a project or enterprise, can be constructed from the HITSP data models managed by the EHR Functions used within the EHR BA, categorized using the HL7 RIM Entity, Role and Action foundation classes.
These concepts are the topic of this presentation

Stakeholder Requirements
What is the system supposed to do?
Under what conditions will the products be used?
Where will the products of the system be used?
How often? How long?
Who will use the products of the system?
Requirements Analysis (“HOW?” using “Action Verbs”)
Analyze functions and Services
Decompose higher level functions to lower level functions
Allocate performance requirements to the functions
Architecture Design (Which hardware/ software elements)
Define the physical architecture
Each part must perform at least one function
Some parts may perform more than one function
Test Specifications
How Requirements-Specifications are validated
Requirements Loop
Ensure all requirements are covered by at least one function
Ensure all functions are justified by a valid requirement (no unnecessary duplication)
Design Loop
Ensure all functions are covered by at least one hardware or software element
Ensure all elements of physical architecture are justified by a valid functional requirement (no unnecessary duplication)
Verification & Validation (V&V) Loop
Each requirement must be verifiable that the solution meets requirements and validated that it meets the user’s needs and expectations.
V&V can be accomplished by: Inspection, Analysis, Demonstration, Test
Test Loop
Ensure all information is covered by test specifications
Ensure all interfaces are covered by test specifications 13

14. Value Proposition of Standards Based Approach
Analysis Pre-Done: Analysts from throughout industry have vetted and contributed to the development of thorough specifications
Less Customization: COTS vendors are already building applications to meet these specifications.
Comprehensive View: Standards provide a way to ensure that requirements and design address all of the necessary issues
Lack of unexpected dependencies late in project: All functions and specifications have been pre-analyzed and defined
Better Interoperability: Standards based approaches will ensure development between all stakeholders are able to communicate at the project and technical level
Across Project Visibility: Normalized requirements and design would allow for “apples to apples” comparison across the portfolio

17. 2010 SAIF Alpha Project The Practical Guide For SOA in Healthcare Volume II Immunization Management Case Study
The Practical Guide for SOA in Healthcare Volume II presents a case study, which adds an Immunization Management Capability (IMC) to Volume I’s SampleHealth’s Service Oriented Architecture (SOA). We used the TOGAF Architecture Development Method (ADM) and HL7 Service Aware Interoperability Framework (SAIF) Enterprise Conformance and Compliance Framework (ECCF). Volume II demonstrates the use of HL7’s EHR System Design Reference Model (EHR-SD RM) linked artifacts (e.g., EHR System Functional Model, FHIM, HITSP, HITEC, HSSP, IHE, NIEM, etc) to provide an initial architectural baseline suitable for an EHR related SOA acquisition, development or certification project. We conclude with lessons learned.

22. SAIF Alpha-Project Conclusions
Effective SOA programs involve cooperation and coordination among a wide variety of business, technical and functional participants from across an organization, including senior management sponsorship, business community ownership, program management, governance, architecture, project level execution, test and certification and sustainment teams. The HL7 EHR-SD-RM helps bring these communities together throughout a Business Capability Lifecycle. It maps capabilities and business Information Exchange Requirements (IERs) to the

23. EHR-S CI-IM EHR System Computationally-Independent Information-Model (Started Jun2010)
This project will produce a set of Constrained Information Models called EHR-S “data profiles”. Each EHR-S data profile corresponds directly with an EHR-S function profile and each EHR-S data profile will include one-or-more Reference Information Model classes. Pairs of EHR-S function profiles and data profiles can be used to define business objects, which can be composed into software components, capabilities, applications, systems and their message exchanges and/or document exchanges and/or services. The superset of EHR-S data profiles is called the EHR-S Computationally-Independent Information-Model, which supports the HL7 Development Process and Service Aware Interoperability Framework. The project will include the development and execution of a communication strategy to ensure that all affected stakeholders are engaged.

24. HL7 RIM (Reference Information Model) Six Core Classes Defining a Semantic Framework which Maintains Clinical Data Context
ENTITY
ROLE
ACT (aka ACTION)
Participation
Role link
Act relationship
ACT – something that has happened or may happen
Entity – a person, animal, organization, or thing
Role – a responsibility of, or part played by, an Entity
Participation – the involvement of a Role in an Act
Act Relationship – a relationship between two Acts
Role Link – a relationship between two Roles.
The HL7 RIM expresses the data content needed in a specific clinical or administrative context and provides an explicit representation of the semantic and lexical connections that exist between the information carried in the fields of HL7 messages.
Language /

27. Harmonization Framework and Exchange Architecture (HF&EA) Started Jun 2010
The first objective of this HL7 Harmonization Framework and Exchange Architecture (HF&EA) project is to define a notional set of architectural artifacts for HL7 projects and EHR System (EHR-S) development or acquisition projects. The second objective is to define the relationships among HL7 architectural artifacts and how they relate to other healthcare related standards and architectural artifacts, which can support a Model Driven Architecture (MDA) waterfall, spiral, agile or other development methodology. The third objective is to be an implementation guide for the use of the HL7 Development Framework (HDF) process and HL7 Service Aware Interoperability Framework Enterprise Compliance and Conformance Framework (SAIF ECCF) structure by which architectural work products are reused or developed, are organized into an Interoperability Specification and used throughout an architecture development project, the governance that should be enacted on these work products, and the scope of the standardization effort itself. The fourth objective is to define a Healthcare Information Exchange Model (H-IEM) for model-driven Healthcare Information Exchange Package Documentation (H-IEPD) and exchange architecture. The fifth objective is to demonstrate how the HDF and ECCF can complement other frameworks such as TOGAF, Agile Scrum, DODAF and Zachman.

SAIF Principles:
Applicable within each of HL7’s three Interoperability Paradigms (IPs),
(i.e., messages, documents, and services).
Provide support for measurable conformance and compliance.
Define appropriate governance structures and processes.
Provide support for directly implementable solutions.
Address the growing disparity between the various solution sets emerging from HL7.
Utilize existing V3/RIM artifacts and expertise to the maximum degree possible.

38. Federal Enterprise Architecture (FEA) www.whitehouse.gov/omb/egov
Performance Reference Model - The FEA PRM is a framework to measure the performance of major IT initiatives and their contribution to program performance. The PRM leverages performance measurement best practices from the public and private sectors, including the Balanced Scorecard, Baldrige Criteria, Value Measurement Methodology, program logic models, the value chain, and the theory of constraints. There is an increased emphasis placed on linkage of investment to agency program performance and the PRM will help agencies produce enhanced performance information. Furthermore, the PRM will assist in: improving the alignment of program goals and objectives with Mission Area goals and objectives; improving communication of program contributions such as technology (input) to outputs and outcomes; and in identifying improvement opportunities that span traditional organizational boundaries.
Business Reference Model - The Business Reference Model (BRM) is a functional-driven framework for describing and organizing the day-to-day business operations of the Federal Government into Lines of Business (LOBs), independent of the agencies that perform the business operation. The BRM is the first layer of the Federal Enterprise Architecture and it is the organizing construct for the analysis of the other four reference models: performance, service components, data, and technology.
Service Component Reference Model - The Service Component Reference Model (SRM) is a functional framework to evaluate to identify government-wide opportunities to leverage IT investments and assets from a service perspective. This model helps understand the services delivered by the government and assess if there is an opportunity to group like services and create leverage opportunities, such as reuse or shared services.
Data Reference Model - The Data Reference Model (DRM) describes at an aggregate level, the data and information required to support the Lines of Business (LOBs). The three elements of data exchange that have been standardized include data description, data context, and data sharing. Establishing a common data model streamlines the information exchange process within and across the Federal Government and facilitates the ability to identify duplicative data resources.
Technical Reference Model - The Technical Reference Model (TRM) establishes a common technical framework for categorizing standards, specifications, and technologies that support and enable the delivery of services. This framework can be leveraged to support the development, delivery, and exchange of business and application components (Service Components) that may be leveraged in a Component-based or Service Oriented Architecture (SOA). Furthermore, it also serves as the foundation to advance the re-use of technology and best practices from each of the Service Components on a government-wide basis.

39. HITSP Clinical Document Components
HITSP Reuse Paradigm:
With HITSP/Capability Communication of Structured Documents, a HL7 Clinical Data Architecture (CDA) document can be composed, from any group of C83 data modules, and then it can be communicated.
Benefit: agile system interoperability.

40. HITSP/C83 Data Module Categories
Module Category
Description
Personal Information
The personal information includes name, address, contact information, personal identification information, ethnic and racial affiliation and marital status of a person
Support
Support includes the patient's sources of support, such as immediate family, relatives and/or guardians. This includes next of kin, caregivers, support organizations, and key contacts relative to healthcare decisions. Support providers may include providers of healthcare related services, such as a personally controlled health record, or registry of emergency contacts
Healthcare Providers
This includes a list of the healthcare providers and organizations that provide or have provided care to the patient
Insurance Providers and Payers
Insurance providers include data about the organizations or individuals who may pay for a patient's healthcare, and the relationships, demographics and identifiers of those individuals with respect to the payer. Such organizations or individuals may be health insurance plans, other payers, guarantors, parties with financial responsibility, some combination of payers or the patient directly

43. SAIF Alpha-Project Description
The Practical Guide for SOA in Healthcare Volume II presents a case study, which adds an
Immunization Management Capability (IMC) to Volume I’s
SampleHealth’s Service Oriented Architecture (SOA). We used the
TOGAF Architecture Development Method (ADM) and
HL7 Service Aware Interoperability Framework (SAIF)
Enterprise Conformance and Compliance Framework (ECCF).
Volume II demonstrates HL7’s EHR System Design Reference Model (EHR-SD RM)
Linking EHR System Functional Model, FHIM, HITSP, HITECH, HSSP, IHE, NIEM
To provide an Exchange Architecture baseline suitable for an EHR related
SOA acquisition, development or certification project.

44. EHR-SD RM Prototype [2008 AHIC Use Cases] Immunization and Response Management (IRM)
The IRM AHIC Use Case and HITSP Interoperability Specification are intended to support current interoperability approaches between EHRs and Immunization Information Systems while allowing for a migration toward emerging interoperability implementations and document sharing environments where PHRs are able to be included in the information flow
The Interoperability Specification also allows for basic electronic information exchanges to enable requirement communications and alerting mechanisms and to lay the foundation for future clinical support capabilities
Scenario 1: Vaccine and Drug Administration and Reporting and
Scenario 2: Vaccine and Drug Inventory Reporting
