Query Health Vendor Advisory Meeting 12/15/2011

Agenda Provide Overview of Query Health Seek Guidance and Feedback on Integration Approaches

Query Health Objective Enable a learning health system to understand population measures of health, performance, disease and quality, while respecting patient privacy, to improve patient and population health and reduce costs.

Query Health Roadmap 4 Expected to create the necessary specifications and recommend standards that will be Proven in Pilot Implementations Allows Organizations to compute population level summaries for various use cases Eventually be part of MU Roadmap once HITSC and ONC approves the standards Vendors will be asked by organizations to incorporate or integrate with Query Health CEDD specifications and standards to support population measures

Improve community understanding of patient population health Clinical Information Question Aggregate Result Clinical Information Questions about disease outbreaks, prevention activities, health research, quality measures, etc.

Distributed Query Networks, Voluntary, No Central Planning Community of participants that agree to interact with each other. There will be many networks; requestors and responders may participate in multiple networks. The network will enforce an initial, but not necessarily final, authorization boundary. Authorized Requestors Participating Responders Query

Use Cases and Requirements Focus on the data from the clinical record (e.g., EHRs, HIEs, payer clinical repositories, PHR, etc.) User stories –Generic – for general distributed queries, to lay a requirements- driven foundation –Expanded Analysis – for the pilots, specific to an outpatient setting, distributed query of clustered metrics related to diabetes

Query Health Specifications and Standards Context Information Requestors Queries Results Queries Results Query Network CIM Responding Organization “1” Responding Organization “N” Four Areas targeted for standardization to promote interoperability 1.Query Envelope to package queries and results 2.Query Format to express queries in a declarative format 3.Results Format to express results in a declarative format 4.Query Data Model to promote common data element definitions across organizations

Query Health Specifications and Standards Specifications PurposeStandards Selected to create the specifications Rationale Query EnvelopeRequired to package queries, results and associated metadata in an interoperable manner PopMedNet QueryEnvelope The Query Envelope allows a generic way to package queries and results and is agnostic to the actual query or results and their formats. In addition the envelope carries the required metadata to enforce the Query Health security and policy sandbox requirements. Query FormatRequired to promote interoperability among the various query network participants within and across query networks HQMF * * - The existing standard has to be modified for Query Health purposes. The HQMF standard allows for expressing a large majority of queries related to Meaningful Use, ACO related queries, Comparative effectiveness, Population measures and basic research related queries. In addition it allows for Queries to be represented in a declarative fashion independent of the implementation language. For Queries which cannot be represented using HQMF the Query Health Reference Implementation will provide native format options to express queries. Results FormatRequired to promote interoperability among the various query network participants within and across query networks QRDA Category III ** ** - The existing standard will have to be analyzed further before finalizing. This was not discussed during the F2F but was mentioned a couple of times. The QRDA Category III allows for returning aggregate or summary level results that will be useful too report results for Meaningful Use, ACO, Comparative effectiveness results and many basic research results related to populations. In addition it allows for Results to be represented in a declarative fashion independent of the implementation language. For Results which cannot be represented using QRDA the Query Health Reference Implementation will provide other options based on MIME Types. Query Data Definitions Required to create executable queries and promote common data definitions between information requestors and responding organizations The Query Data Definitions will be created as part of the Query Health Initiative based on sections in C32. The Query Data Definitions will allow query composers to know what data exists for queries and also allows for a common definition of the data across organizations. The C32 sections were chosen as a source to identify the data elements since it is supported by a large majority of EMR’s.

Query Health Roadmap 15 Expected to create the necessary specifications and recommend standards that will be Proven in Pilot Implementations Allows Organizations to compute population level summaries for various use cases Eventually be part of MU Roadmap once HITSC and ONC approves the standards Vendors will be asked by organizations to incorporate or integrate with Query Health CEDD specifications and standards to support population measures

Open Feedback Session 16 Vendors will be asked by organizations to incorporate or integrate with CEDD specifications and standards to support population measures, Care Transitions using standards such as the Green CDA / Consolidated CDA Query Health CEDD Specifications aligned with the above and could provide a potential path for the vendors to incorporate the above standards Are there ways to work together with the vendor community that will help all the vendors in the long run Are there common data elements, concept mapping etc.. that we can focus on together

Open Feedback Session Cont’d 17 Feasibility of Vendors executing Queries and Returning Results without using Query Health Reference Implementation components Modified HQMF for executing queries Modified QRDA for returning results

Open Feedback Session Cont’d 18 Best practices to integrate source data to the Query Health Reference Implementation C32 / CDA Level 3 type of document Importers Quality of C32 data Is it Structured data Consistency of vocabularies/codes across vendors

Open Feedback Session Cont’d 19 Best practices to integrate source data to the Query Health Reference Implementation ETL Processing What kind of frameworks would be required for ETL processing to be successful ? Data Mapping Concept to Code Mapping Other Approaches to integrate data sources
