4 Overview of VA

5 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 Community-Based Hospital-Based Mobile Independent 300 Vet Centers ID:15 Created for VHA Overview Version 1.6/13/2011 Updated 1/22/2013 to reflect FY th Quarter pocket card: 70 Mobile Vet Centers 102 Domiciliary Residential Rehabilitation Programs 134 Community Living Centers Source: FY 2012 End-of-Year Pocket Card

9 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) Home-based primary care Case-management Specialty clinics, e.g., heart failure Telehealth Palliative care Broad range of clinical programs designed to improve care for Veterans with complex chronic illness VHA provides a broad range of programs for patients with chronic illness to improve outcomes and prevent hospitalizations: Home-based primary care Case-management Specialty clinics, e.g., heart failure Telehealth Palliative care However, no systematic way of targeting programs or identifying patients who might benefit most Knowledge of a patient’s risk of adverse events could help to target delivery of intensive services to those with the potential to derive the most benefit Doctors and nurses cannot accurately predict who is at highest risk of deteriorating or dying Predictive analytics using data from many sources including EHR could help to identify highest risk patients and target services.

10 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

11 Moving From What’s Wrong
Data Silos Data Juxtaposition Data + Workflow Integration

12 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

13 Standard Orders

14 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

15 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

16 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

17 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

18 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

19 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

20 VistA Evolution

21 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”

22 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

Initial Operating Capability (IOC) Office of the National Coordinator (ONC) Certification 2014 Criteria Interoperability Full Operating Capability (FOC) 2014 2015 2016 2017

24 VistA Evolution Management Approach
Continuous feedback and improvement Engaged customers and stakeholders Just in time requirements An agile-UX-Value Management approach allows high-level, very broad modeling and planning at the beginning of the project to address the majority usability, UI, and project risks facing the team.  Value Management Feature Driven Design Agile Principles Focuses on system behavior and usability Requires some system modeling and design upfront Plan the program before starting work

25 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

26 VLER and IPO define the interoperability standard
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 Vision A user experience that integrates information for improved quality and effective clinical decision taking Multi-provider information sharing tailored to the patient's clinical condition, care goals, and physician best practices Provides the capability for clinicians and researchers to define and manage patient population data.  A patient population is a cohort formed by applying specific criteria (e.g., age, weight, disease, allergies, location).   "Rural Diabetic Veteran ages 55-65 exhibiting macular degeneration" would be a type of patient population Management of activities that improve human and material resource utilization and clarify plans of care Explicit incorporation of patient goals in the care plan, to support patient-defined terms of success Enterprise-wide deployment Standard Data Model Open Source/ Community Partners Acronyms: DoD – Department of Defense IHS – Indian Health Service VBA – Veterans Benefits Administration

27 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.

28 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”

29 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

30 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.

31 VistA Evolution Program Principles
This VistA Evolution Program Plan is 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.

32 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.

33 VistA Evolution Program Plan Purpose
The Program Plan defines 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

34 VistA Evolution: The Product
The VistA Evolution product provides the infrastructure and open, extensible platform on which tools and services can be integrated in support of Veterans’ evolving needs, in pace with the technological landscape.
