VISNs.
• 152 Medical Centers
• 990 Outpatient Clinics
821 Community-Based
152 Hospital-Based
11 Mobile
6 Independent
• 300 Vet Centers
• 70 Mobile Vet Centers
• 102 Domiciliary Residential
Rehabilitation Programs
• 134 Community Living Centers

Telehealth
• 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)

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

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”

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.
VETERANS HEALTH ADMINISTRATION
27
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”
VETERANS HEALTH ADMINISTRATION
28
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
VETERANS HEALTH ADMINISTRATION
29
VistA Evolution Program Objectives
1. 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.
VETERANS HEALTH ADMINISTRATION

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 stateof-the-art technology while leveraging the knowledge base and processes
that create a patient-centric health care environment.
VETERANS HEALTH ADMINISTRATION
31
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.
