include component="page" wikiName="siframework" page="Daf Header" media type="custom" key="20312646" =**DAF Project Charter**= Click for the Word version of the Charter page. =Challenge= The nation is reaching a critical mass of HealthIT systems (EHRs, Data Warehouses etc) that comply with data and vocabulary standards. The wide deployment of HealthIT systems has created unique opportunities for providers, provider support teams, healthcare professionals and organizations etc. to access and use the patient data that is already collected during clinical workflows. While the Health IT systems provide many access paths through their pre-defined interactions between a user and the system, they are limited in their support for data queries, APIs, or services to access data sets as needed. Where Health IT systems provide data access, they likely do not use industry standard access methods. Increasing support for this class of data access, using industry standards, would enable other applications to expand the ability of users to create value out of their data without having to rely on the predefined access paths. Allowing access to this data can enable a provider to further analyze the collected data to understand a patient’s overall health, the health of a provider’s collective patient population, and use the data to power innovative new applications and tools to take better care of patients and populations. However accessing data from the HealthIT systems presents some challenges as outlined below:
 * Who is accessing the data, why are they accessing the data and what are the challenges faced in accessing the data?
 * Providers, healthcare professionals etc., want to access data **within their own organization** so that they can use additional care management tools appropriate for individual patient and groups of patients. The ability for providers and their clinical support staff to access their own data allows for the use of innovative new applications that can improve patient engagement and care.
 * Providers, healthcare professionals etc., want to access data **from external organizations** visited by patients for specific healthcare needs. Accessing data from an external organization requires the appropriate authentication and authorization before data can be made available.
 * Government agencies requiring access to data from various organizations to comply with laws and regulations.


 * What are the types of data accesses that need to be supported? While there is a large spectrum of data granularity required based on the business requirements they can be abstracted using example dimensions represented in the table below. (Note: The Data Access mechanism dimension can keep extending depending on the types of information that the provider is trying to access, one example is accessing decision support information within a clinical workflow).

The table below highlights the complexity of the Data Access Framework by including sample Data Access Mechanisms and highlights the granularity of the data being accessed at both the Patient and Population level. For a definition of the various columns presented in the table, please refer to DAF Terminology. The Data Access Framework Initiative recognizes that solving the various challenges outlined above requires a Query stack that is composed of Modular and Substitutable standards.
 * The challenge is to select appropriate mechanisms to access the data described in the above table in a uniform way both within an organization and from an external organization.
 * While query concepts can be used to access the data, standardizing query mechanisms for the variety of data access needs presents a significant technical challenge.
 * To add to the above challenges, Interoperable Implementation of Data Access Framework in the real-world will require selection of multiple standards across multiple layers. These standards can be visualized as a Query stack (Draft) as shown in the figure on the left hand side. The Query stack identifies the various layers for which standards would have to be selected and implemented. An example of an existing Data Access Framework using IHE XCA Query stack is also shown to aid the reader.
 * Modularity is the ability to keep the various layers of standards independent of each other. (e.g., Transport Layer standards should be independent of query structure standards which should be independent of query result standards).
 * Substitutability is the ability to replace a particular standard without affecting the other layers of the query stack. (e.g., depending on the business requirements the query structure might be best represented using ebRIM/ebRS or HL7 FHIR or HL7 HQMF).

The goal for the initiative is to
 * Enable Local and Targeted data access using the various data access mechanisms (document based, data element based, quality measure based, etc.)
 * Identify privacy and other necessary metadata to enable the various data access mechanisms
 * Modularize the query stack into modular layers (transport, query structure, query results, authentication, etc.) and allow for substitutability at each layer of the query stack. The extent of the modularity and substitutability that can be achieved will be determined by working with the community experts and experimenting with real-world technical feasibility.
 * Identify the set of modular components and industry standards that should be __assembled together as valid combinations to promote interoperability__ for the various business requirements of the community. Identifying the valid combinations to be used based on business requirements should address the community concern around substitutability leading to a large number of combinations which may not be interoperable.

=Scope Statement= The Data Access Framework will be built incrementally by first focusing on Local Access via Intra-Organization query, Targeted Access via Inter-Organization query. Finally Multiple Data Source Access via Distributed Queries is a future goal but not-in-scope for this initiative. This incremental path and focus areas are shown in the figure below. The work of this initiative will be done in 2 phases: The following capabilities are __In-Scope__: The following capabilities may influence the operational deployment of the standards selected by DAF, however they will __not be addressed__ by the DAF initiative. =Value Statement= The value of the Data Access Framework in the real world is the ability to use multiple modular and substitutable standards as necessary to implement sample scenarios listed in the table below. //Note - The Multiple Data Source Access scenarios in the table are examples of work done in the Query Health Initiative and are out of scope. These are just examples to demonstrate the applicability of Data Access Framework.// The above table is for example purposes only and does not convey actual work products. Appropriate Scenarios and User Stories to support this initiative will be further detailed during the Use Case and functional requirements phase with assistance from the community. =Target Outcomes= The target outcomes for the Data Access Framework Initiative include =Strategic Alignment= The Data Access Framework will strategically align with > > =Timeline= The Data Access Framework Initiative timeline for the first 18 months is shown below. Slide one (1) illustrates the first 6 months; Slide two (2) illustrates months 7-12; Slide three illustrates months 13-18. The initiative timeline will be refined and adjusted as necessary.

 * 2) Phase 2 is focused on Targeted Access via Inter Organization Query
 * Identify the business and functional requirements for Local Access and Targeted Access.
 * Define the modular layers for Data Access Framework to support identified business and functional requirements.
 * Identify the existing standards that can be used for each layer of the Data Access Framework including guidance for substitutability of standards for both Local Access and Targeted Access.
 * Identify the existing information models, vocabularies, terminologies from MU2 and other S&I Framework initiatives that can be leveraged for defining the semantics for the DAF Initiative.
 * Identify any metadata (including security, privacy and provenance) standards and vocabularies that can be leveraged for the DAF initiative.
 * Define Implementation Guides leveraging existing standards where necessary to structure queries and query results for identified business and functional requirements.
 * Identify standardized APIs that allow applications to query data in a consistent manner across HealthIT systems.
 * Creating or modifying policies that allow queries to be executed within an organization or across organizations.
 * These Policies include Trust establishment between organizations, any governance required, data use agreements, privacy laws, authorization policies related to data disclosure etc.
 * Patient identity matching policies, matching rules and matching algorithms to identify patients and their related clinical data.
 * Patient consent policies for query purposes which vary from organization to organization.
 * Definition of __new__ clinical domains, information models along with associated vocabularies and terminologies.
 * Discovery of Query Service end points for Local Access or Targeted Access.
 * Specifying standards for the inner workings of Health IT systems (e.g., EHRs might store data in multiple databases and may have to access this data to respond to a query. The exact mechanisms used by the EHR to store and retrieve their internal data will not be examined or standardized by the DAF initiative).
 * Specifying access control policies or mechanisms that allow a Patient access to their own data.

 * Risk #1: Trying to address several interoperability problems in a single Initiative
 * Mitigation: Constrain the use cases and requirements within a manageable scope so that readily available standards are leveraged.


 * Risk #2: Projected timeline may not be achievable due to various reasons such as lack of community input, delays in achieving consensus on artifacts, and unavailability of relevant experience
 * Mitigation: Work with community to refine timeline as the initiative progresses and adjust timelines as needed.


 * Risk #3: EHR vendors have already implemented some query standards and may not have the availability to participate due to other priorities such as Meaningful Use
 * Mitigation: Include support for existing standards so that vendors can reuse existing implementations.


 * Risk #4: Modularity and Substitutability identifies too many combinations of how to access data many of which may not be used in the real-world.
 * Mitigation: Identify the combinations based on the existing use cases and existing standards that are most likely to be adopted and implemented in the real-world.

>
 * Risk #5: Ensuring potential Pilot Sites are identified and engaged throughout the initiative, so that the standards can be pilot tested in the real world
 * Mitigation: Perform outreach and frequent communication, identify tangible Data Access Framework benefits to the potential pilot organization
 * Mitigation: If the standards selected are already implemented and used in the real-world, then pilot feedback will be obtained from these real-world implementations.
 * Risk #6: Vendors use a variety of other protocols and programming languages to access the query data
 * Mitigation: Standards selected will be independent of programming languages and implementation technologies so that vendors can use their choice of programming languages and implementation technologies. In addition implementation guidance will provide the necessary context for vendors to implement the selected standards.
