Big Data and VistA Evolution Presentation to Open Source Electronic Health Record Alliance (OSEHRA) Architecture Work Group Theresa A. Cullen, MD, MS Chief Medical Information Officer Director, Health Informatics Office of Informatics and Analytics Veterans Health Administration Department of Veterans Affairs
Agenda • Overview of the Department of Veterans Affairs (VA) • Big Data • VistA Evolution
Community Population Patient, Provider, and Patient Family Patient and Provider Patient . . . . .
Hospital System to Health System In 1996, VA began the creation of Veterans Integrated Service Networks (VISNs) to transform VA Health Care from a “Hospital System” to a “Health System.” Veterans Health Administration (VHA) currently has 21 VISNs. • 152 Medical Centers • 990 Outpatient Clinics 821 Community-Based 152 Hospital-Based 11 Mobile 6 Independent • 300Vet Centers • 70 Mobile Vet Centers • 102 Domiciliary Residential Rehabilitation Programs • 134Community Living Centers Source: FY 2012 End-of-Year Pocket Card
VA’s Health Care Delivery Model • Personalized, Proactive and Patient-Driven • Team Care • Continuous Improvement • Data-Driven, Evidence-Based • Value • Prevention / Population Health Coordinated Care
Collect and Blend the Big Data CUT MIX DICE BLEND PARSE
Secondary Data Use: Research and Predictive Analytics Capabilities • Providers can’t accurately predict Veterans at highest risk of deterioration • Patient Aligned Care Team Registered Nurse (RN) Care Managers charged to coordinate care • No systematic way to identify Veterans who might benefit most predictive analytics using data from Electronic Health Record (EHR) Broad range of clinical programs designed to improve care for Veterans with complex chronic illness
What’s Wrong: Data-Domain Centric • Building blocks of EHR are data domains • Meds, Labs, Rad, Notes, Diagnoses, etc. • Results in bad thought-flow and workflow
Implications of Conceptual Approach • Goal - construct user-interface components to facilitate clinical reasoning and work • Address basic cognitive needs – then reuse or reconfigure for most health care processes • Avoid “an app for that,” while allowing for extensibility
Developing Context-Sensitive Orders • 30 million records – 20 years of data mined to identify relationships between • Problems • Laboratory results • Prescriptions • Procedures • Orders • Location • Provider • Patient • 15,000 conditions and 10,000 orders
Common Test and Drug Orders • Epigastric pain • CBC with diff • Chemistry panel • Helicobacter pylori • Lipase • Amylase • Upper GI endoscopy • Abdominal ultrasound • CT abdomen w/o contrast • Omeprazole • Ranitidine • Amphogel • Rabeprazole • Promethazine • Sucralfate • Metronidazole • Metoclopramide • Docusate
Characteristics of VHA Analytic Approach • Treat corporate data as strategic resource, available to entire organization • Maximize understanding of organizational processes and outcomes to promote learning and improvement • Invest in relevant, role-based training in analytics so tools are available widely and not just to a few
Products • For clinicians • Real-time, structured data collection • Population and panel management tools • For leadership • Understanding organizational performance and vulnerabilities • For public/consumers • Unparalleled transparency and public reporting
Care Assessment Need (CAN) Report • CAN provides estimated probability of death/hospital admission w/in specified time frame (90d or 1 yr) • Score expressed as a percentile 0-99; higher score indicate follow-up assessment • Provides patient level detail • Accessible through VHA Support Service Center (VSSC) website and Computerized Patient Record (CPRS) tools menu • For primary care providers, and/or nurse care manager • Model developed in collaboration with VA researchers and policy leaders
VHA’s Analytic Journey – Summary Themes • Leverage and integrate information (break down silos) to gain insight and efficiency • Collaborate across multiple data sources and agencies (e.g., Veterans Benefits Administration, Department of Housing and Urban Development (HUD), Department of Health and Human Services (HHS)) • Move from retrospective performance reports to real-time prediction, decision support, and practice support • Enhance analytic skills throughout Veterans Health Administration (VHA) workforce • Promote transparency and accountability
Background • In 2013, VA and Department of Defense (DoD) Secretaries made decisions that require a change in EHR strategy • The VA EHR core will be VistA-based • Our mission has not changed “to care for him who shall have borne the battle, and for his widow, and his orphan”
Current VA Landscape VLER Health Connected Health Over the past several years, various products have been developed across the VA landscape, creating a complex suite of applications Janus JLV VistA Web VistA CPRS iEHR RDVs CAPRI VistA Standardization HMP Acronyms: CAPRI – Compensation and Pension Record Interchange HMP – Health Management Platform iEHR – integrated Electronic Health Record JLV – Joint Legacy Viewer RDV – Remote Data Views ‘Conceptual’ representation of current EHR/Health Information Technology Landscape
VistA Evolution Program Goals • The VistA Evolution Program will support this strategic plan through continual investment and delivery of scalable and modular EHR and Health Information Technology (IT) products to improve the quality, safety, efficiency, and satisfaction in health care for Veterans through: • Interoperability • Implementation of an open and extensible EHR system • Establishment of interoperability between VA and DoD EHR systems • Re-engineering of business processes in collaboration with users of health IT
Interoperability VistA Federal Partners (DOD, IHS) • By end of 2017, we will have an architecture and framework that supports interoperability, care coordination, meaningful use and partnership and which has been certified to the Office of National Coordinator (ONC) 2017 Edition certification criteria to support meaningful use demonstration by VA providers and hospitals Integrated Architecture and Services User Experience VBA Care Coordination Framework VLER and IPO define the interoperability standard Standard Data Model Open Source/ Community Partners • Acronyms: • DoD – Department of Defense • IHS – Indian Health Service • VBA – Veterans Benefits Administration
Three Key Interoperability Concepts • Technical (syntactic) Interoperability • Allows computers to reliably exchange data, so it can be read at least by humans. • Accomplished with messaging protocols and data formats. • Semantic Interoperability • Allows computers to unambiguously and consistently determine meaning of the data for presentation and decision support. • Accomplished with standardized terminologies like ICD10 and SNOMed. • Process Interoperability • Allows computers to exchange and track workflows as patients or orders move between organizations; includes care plans. • Accomplished with standardized business process notation or workflow protocols. • Ex. 1: sending prescription requests from VistA to community pharmacies; • Ex. 2: tracking care plans for follow-up on cancer suspicion from X-ray • Ex. 3: continuing polytrauma care plans as patients move between VA and DoD.
How Do We Get to Seamless Interoperability ? Principles • Mapping to National Standards is the correct approach • VA investment will improve interoperability with DoD and other health care partners • “First No Harm” • VA must balance permitted uses of shared data with our level of confidence in coding and content accuracy • The possibility and degree of harm • 100% mediation is NOT to be expected • Mediation rates in Clinical/Health Data Repository (CHDR) are ~80% • This is still an improvement over “No Data”
How Do We Get to Seamless Interoperability ? Interagency Program Office (IPO) • Provide and maintain complete, accurate, and meaningfully interoperable data from all domains required to achieve clinical objectives and meet regulatory requirements (semantic interoperability) VistA Evolution • Improve technical infrastructure for health data interoperability while reducing overall system complexity (improved syntactic interoperability) • Convert to standards-based services, formats, protocols, and data models • Enable expanded and improved data exchange with partner providers
VistA Evolution Program Objectives Provide program structure, management ,and governance to oversee requirements management, acquisition, risk management, communications, training, and transition planning. 2. Establish and maintain flexible system and enterprise architectures that support interoperability with internal and external partners, and support new applications and features that meet clinical needs. 3. Establish and maintain methods to develop business (clinical and administrative) processes and to revise existing procedures and policies that advance VA health care and health informatics capabilities.
VistA Evolution Program Principles This VistA Evolution Program Planis based on the following principles to ensure the highest standards of program execution: • Focus on our Servicemembers, Veterans, and their family members. • Enable health care that applies the appropriate and most efficient resource to the task of providing the highest quality care while maintaining a focus on prudent custodianship of tax payer resources. • A cohesive, forward-looking architecture which maintains affordability while enabling a steady and reliable evolution forward, incorporating state-of-the-art technology while leveraging the knowledge base and processes that create a patient-centric health care environment.
VistA Evolution Program Management The importance, size, and complexity of VistA Evolution requires adoption of robust constructs for organization and governance structure. • The organization of scope, schedule, and cost must include the business, technical, and program functions. • The organizing framework must be detailed enough to practice Value Management yet ‘light’ enough to enable agile management and development when appropriate. • The work breakdown structure must align to iEHR capabilities and to business functions • Consensus is needed on artifacts and frameworks used to execute the program.
VistA Evolution Program Plan Purpose • The Program Plandefines the Who and How of the VistA Evolution Program • Management Approach • Governance for Program Planning, Change Control, and Risk Management • VistA Evolution Product Approach • EHR Certification and Meaningful Use • Requirements Management Strategy • Communications Strategy • Training Strategy • Transition Strategy • Work Breakdown Structure
