popHealth Overview
■ popHealth is an Open-Source Clinical Quality Measure database
and reporting engine presented through a web-based interface
■ Centralized repository of clinical data
■ Data is sent from EHRs via nationally recognized standards
– Consolidated Clinical Data Architecture (C-CDA) Architecture Continuity of
Care (CCD)Document
– QRDA (Quality Reporting Data Architecture) Cat 1 or 3 Document
■ Clinical Quality Measures (CQMs) are calculated for providers
and presented through a web-based interface
– Drill down ability to the provider and patient-level data
■ Track trends in quality and health over time
■ Capture CQMs for Meaningful Use Reporting
■ September 2009 - popHealth started as a prototype, proof-of-concept for a Clinical Quality Measure (CQM) reporting module: popHealth v0.1
■ September 2010 - popHealth formally supported by ONC as a MU Stage 1 reference implementation
■ 2011 – popHealth certified
■ January 2012 – v1.4 support for multi-provider with enhanced functionality released
■ December 2012 - v2.0 support for MU Stage 2 CQMs for EPs released
■ February 2013 – v2.1.2 with enhanced functionality released
■ June 2014 - v3.0 with upgraded UI, enhanced technical architecture, support for QRDA import released
■ Spring 2014 v3 certified
■ Fall 2014 – transition to Open Source Community from ONC
History of popHealth
■Entities are using popHealth in a variety of ways
■Active User Community– Monthly user group meetings
– Includes active users and interested users
■Currently Managed by ONC, Moving to Open Source
Community– OSEHRA selected to manage Open Source Community
– Process of moving to OSEHRA has begun, will take place
over the next few months
■ EHR Upgrades to 2014 CEHRT impacting popHealth– QRDA Documents becoming available but issues due to being a
new standard
– CCD v1.1 not always working, additional testing required
Current Status
■popHealth Server
–Ruby (version 2.1.1) on Rails (version 4.1.2 or higher)
■Database
–MongoDB (version 2.0.1) *depends on the host server
■CQM Calculation
– Leverages MapReduce framework in MongoDB
■popHealth Internal Measure Representation
–Uses JSON and JavaScript
Technology Stack
■ popHealth is Open Source prototype software that was
developed by MITRE through a grant from ONC
■ Pros
– No cost to purchase
– Active Open Source Community
– All users benefit from enhancements/contributions back to the Open
Source Community
■ Cons
– “Free like a puppy”
– Documentation is lacking and support is voluntary through Open
Source Community
– Requires skill set that is unusual:
HL7, QRDA standards Mongo DB Ruby on Rails JSON
Implementation Challenges
CQM Reporting for Meaningful Use
■ Northwestern University Medical System
– Feed data from various EHRs (through their data warehouse) to popHealth for CQM reporting for all entities in health system
■ VA
– MITRE working to connect popHealth to VA’s Corporate Data Warehouse (CDW) forCQM reporting
■ Wyoming Medicaid
– Database for QRDA Cat 3 data (CQM data) that is entered by providers
– Ability to rank providers into tiers for payment based on CQM rates
– Future plans for eCQM submission by accepting QRDA Cat 3 documents
Current popHealth Use Cases
Current popHealth Use Cases
CQM Reporting for Other Purposes
■ eHealthConnecticut (CT Regional Extension Center)
– FQHCs (CHCs) send CCD data to popHealth database
– Centralized clinical database data from FHQCs
– Use for CQMs and other clinical data reporting needs
– Unexpected outcome is workflow improvement to resolve data issues
– Used for CQM measurement for CT DPH SHAPE grant
■ IL DPH
– FQHCs (CHCs) send CCD data to popHealth database
– Used for CQMs and popHealth dashboards to drive clinic improvements in hypertension management
Consolidated CDA
■ Output of the effort to create one guide that could be used for implementation and analysis of documents within the CDA standard
■ The Consolidated CDA solution is a library of reusable CDA templates
■ Templates can be utilized at multiple levels within a CDA document:
– Level 1: Document Level Templates, such as CCD or Discharge Summary, can be utilized to define a template for the document as a whole.
– Level 2: Section Level Templates, such as Allergies or Medications, can be utilized to define what specific information will be included in each section.
– Level 3: Entry Level Templates, such as specific Observations or Procedures, can be utilized to define how the information is encoded within each section.
■ Consolidated CDA has a document level template for CCD
■ QRDA uses parts of C-CDA framework but is not a template
■ Part of C-CDA Architecture
■ Extensive clinical data
– Allergies: RxNorm*, SNOMED-CT*
– Care Goals, Social History, Medical Equipment: SNOMED-CT*
– Conditions: SNOMED-CT*, ICD-9-CM, ICD-10-CM
– Encounters: CPT
– Immunizations, Medications: RxNorm*, CVX*
– Procedures: CPT, ICD-9-CM, ICD-10-CM, SNOMED-CT*
– Vitals, Results, Assessments: LOINC*, SNOMED-CT*
– Communications: SNOMED-CT
■ * preferred
■ All continuity of care entries are time-stamped
■ Results and vitals must be provided structured with units and
values
Continuity of Care Document
QRDA Architecture
■ HL7 QRDA is a standard document format for the exchange of electronic clinical quality measure (eCQM) data.
■ QRDA reports contain data extracted from electronic health records (EHRs) and other information technology systems. QRDA reports are used for the exchange of eCQM data between systems for a variety of quality measurement and reporting initiatives.
■ QRDA makes use of CDA templates, which are business rules for representing clinical data consistently. Many QRDA templates are reused from the HL7 Consolidated CDA (C-CDA) standard.
■ Templates defined in the QRDA Category I and III enable consistent representations of quality reporting data to streamline implementations and promote interoperability.
QRDA Documents
■ A QRDA Category I report is an individual patient quality report. Each report contains quality data for one patient for one or more eCQMs, where the data elements in the report are defined by the particular measure(s) being reported. A QRDA Category I report contains raw applicable patient data (e.g., the specific dates of an encounter, the clinical condition) using standardized coded data (e.g., ICD-9-CM, SNOMED CT®). When pooled and analyzed, each report contributes the quality data.
■ A QRDA Category III report is a standard structure to use in reporting aggregate quality measure data. Each report contains aggregate quality data for one provider for one or more eCQMs. a necessary to calculate population measure metrics.
CCD vs. QRDA Cat I
CCD/CCD 1.1
■ Clinical summary document for patient history of procedures, encounters, allergies, medications, etc.
■ Main body of data contains different sections for different clinical data components e.g. medical history, procedures, medications, etc.
■ The data sections are larger and have more general templates for procedures, encounters, etc.
QRDA Cat 1
■ QRDA reports are generated based on a CQM request. The data contained in the QRDA file is specific to certain CQMs.
■ Main body of data is divided into three segments: -reporting measure(s) -reporting parameters (rep period) - patient data
■ Templates are more specific and thorough, with smaller general sub groups.
■ Newer standard – less tested
