The Healthcare “Vertical”: A Global ContextThe Healthcare “Vertical”: A Global Context

• In almost every culture, healthcare is being viewed as “broken”

• Demand ubiquitously is outpacing supply

• To date, Information Technology investments in healthcare have been limited

• Countries with the means to do so are investing in IT

– Australia (NeHTA: http://www.nehta.gov.au )

– Canada (Infoway: http://www.infoway-inforoute.ca/ )

– United Kingdom (NPfIT: http://www.connectingforhealth.nhs.uk/ )

– United States (NHII, RHIOs, … http://www.os.dhhs.gov/healthit/ )

– Others….

• Unprecedented participation and collaboration internationally

Healthcare’s ChallengesHealthcare’s Challenges

• Funding is sparse everywhere

• IT is competing with direct patient care for $$$

• There are few incentives and many risks for organizations to share information

• Information content is very diverse and complex, and is not consistently represented by practitioners

• The volumes of data are enormous

• The institutional culture is still very much paper-based

• There is an inherent lack of infrastructure within and across care organizations

• Software products that are available are largely proprietary

The Premise Contradicted (Today’s View)The Premise Contradicted (Today’s View)

• Healthcare as a market sector has viewed IT investment as an expense and not as an investment

• Most IT investment to date has been administratively or financially focused

• The bulk of Healthcare IT in use address departmental or niche needs

• Integration of data within departments is common

• Integration of data within care institutions is not uncommon

• Integration of data within enterprises is uncommon

• Integration of data across enterprises is unheard of

VA’s Current EnvironmentVA’s Current Environment

• VistA, the VHA EHR, is in use ubiquituously across the VA enterprise (and also outside the US)

• All clinical systems are integrated (Clinician desktop, pharmacy, laboratory, radiology, etc)

• Data is available from any VA point-of-care

• Beneficiaries can self-enter family history and self-care progress notes

• VA CPOE numbers exceed 90%

• VistA is cited by the Institute of Medicine as the world’s leading EHR

……And they’re re-engineering the whole thingAnd they’re re-engineering the whole thing

• Why? The premise. That’s why.

• Every VistA system instance is different

• Data quality is inconsistent site-to-site

• Not all data is represented formally using clinical terminologies

• Business rules are implemented inconsistently in different parts of the application suite

• [System] Quality of service differs site-to-site

• High maintenance costs (in both dollars and time)

• ~50% of their beneficiaries receive care outside of VA

Some of their business objectives…Some of their business objectives…

• Improve the ability to care for veterans

• Improve quality of care from improved data quality, consistency

• Improve access to information where and when it is needed

• Allow for better management of chronic disease conditions

• Increase efficiencies allow for improved access to care (e.g., “do more with less”)

• Improve consistency of the practice of healthcare via clinical guideline conformance

The VA Approach…The VA Approach…

• Migrate current applications into a service-oriented architecture

• Re-platform the application into current technologies

• Minimize vendor lock-in risk through use of open standards

• Standardize on an information model and terminologies for consistent semantics

• Recognize that healthcare is a community and solving it institutionally only solves it 50%

This is the reason interoperability and standards are essential!

What is Interoperability?What is Interoperability?

• According to IEEE, interoperability is defined as:

– the ability of two or more systems or components to exchange information and to use the information that has been exchanged

• Why do we care?

– No organization exists in a vacuum

– Increasingly, business pressures are driving organizations to collaborate and interchange data with their peers

– Integration and dependencies between market sectors are increasingly important

– Our ability to integrate drives consumer value

– Consumers are increasingly empowered

The 20 Second Interoperability QuizThe 20 Second Interoperability Quiz

Are you interoperable…

• … if you and your business partners “speak” different languages

• … if gender = “01” means “male” in your business and “female” for your business partner?

• …if the primary context for information sharing is e-mail or fax?

• … if electronic data is exchanged via CD-ROM, or DVD-ROM?

• …if you use XML?

• …if you use Web Services?

Measuring InteroperabilityMeasuring Interoperability

• NeHTA (the Australian National e-Health Transition Authority) published an Interoperability Maturity Model

– It defines a rigorous method of assessing and measuring interoperability

– It is based on the maturity levels defined in the Carnegie-Mellon Capability Maturity Model (CMMI)

– It identifies dimensions of interoperability, namely:

• Organisational

• Informational

• Technical

Guiding Principles Guiding Principles

• Systems must add value to healthcare stakeholders (patients, caregivers, and organizations)

• Information Technology (IT) cannot “fix” business problems

• I.T. does not exist in a vacuum

• We cannot optimize the continuum of care without considering flow between practitioners, departments, and facilities

• A useful “tool” to understand large complex environments is to “separate concerns”*:

– Business (Enterprise) View

– Information View

– Systems View

– Technologies View

• The difference between system success and failure lies in the “small stuff” – details matter!

* *Separation of concerns based upon ISO RM-ODP Specification

Health IT, Enterprise Architecture, and Business Health IT, Enterprise Architecture, and Business ChangeChange

• What is architecture?

• What is Enterprise Architecture?

• Is Health Enterprise Architecture different? Why?

• Why do I care?

• Architecture forms the foundation for supporting and integrating IT and applications

• Enterprise Architecture is the discipline devoted to aligning IT investments with business needs

• Yes and no. The core concept is identical in healthcare as other industries. That said, the information and workflow complexities “change the game”

• Ultimately, systems will only fit within the fabric of a health organization if they are architected in. If not, we have standalone “one-offs” that impede workflow and adversely affect both patients and caregivers.

““Enterprise Architecture 101”Enterprise Architecture 101”

• The practice of aligning IT with business objectives– Identifying unplanned redundancy in work processes and systems– Rationalizing systems and planning investment wisely– Establishing target environment and a viable migration path

• Addresses all facets of IT and the business:– Core business capabilities and business lines– Identification of business functions– Identification of IT needed to support the business

• Multiple Views of IT:– Information content– Systems (computational) view– Technology (infrastructure) view– Process (engineering) view

• …to serve as a catalyst positively influencing government health IT investments

• …to galvanize the private sector through Government-demonstrated leadership

• …to articulate and capture the “to be” and help organizations achieve it

• …to characterize how and where approved standards are used

• …to shape and frame interoperability intra- and inter-organizationally

• Clarify IT responsibilities within your organization– Establish authoritative systems and data sources– Use standards “wherever systems touch”– Focus on information quality

• Take a 20+ year view– The health record must be durable– The technologies will not be

• You are not alone…– Healthcare is a community discipline– Organizations, systems, products, and technologies all play a role– There will be no single marketplace “winner”

Make IT a Business Enabler Make IT a Business Enabler

• Conduct Enterprise Architecture planning to understand the business

– What is the “state of affairs” today?– Where do we want to be tomorrow?

• Work with the stakeholder community to identify desired outcomes

– Focus early priorities on early returned investment– Identify and capture meaningful metrics– Validation should be “round trip” based upon observed impacts

• Reflect IT as a function of the business– How effectively are business needs being captured?– How are stakeholder interests being assured during system

implementation?– How are education, training, and process integration being addressed?

Five success measures of your architecture…Five success measures of your architecture…

5) Durable, with decreasing rate of change- Evolution, not revolution. If you get it right, changes become small and

incremental

4) Standards-based, with variances that are localized to minimize impact. - Build on existing work

- Depart only where you need to

- Any time two things touch, that touch-point should be a standard

3) Product-neutral- Organizations cannot afford to base their entire future on a dependency of any

one product

4) Clear- Make sure you architecture is understandable, concise, and accurate

- Use “separation of concerns” and “viewpoints”

- Make sure you architecture is suitable for its intent

5) Useful, as architectures that sit on shelves add no value.

Five Keys For Overall SuccessFive Keys For Overall Success

1) Leadership must come from the “business” community

2) Define success measures with meaningful business outcomes

3) Design your architecture to realize the impacts you hope to achieve

4) Recognize that while every organization is unique, their challenges aren’t

5) The future isn’t the hard part. Building it while you are “moving” is.
