“An essential first lesson is that ideally, system components should be not only interoperable
but also substitutable.”

HITECH
![Page 14: Meaningful Use Stage 2 - etouches · PDF fileMeaningful Use Stage 2 Working With What You Get Pascal Pfiffner, MD, PhD Computational Health Informatics Program Boston Children’s](https://reader031.fdocuments.net/reader031/viewer/2022022503/5ab31b337f8b9a1d168e1e53/html5/thumbnails/14.jpg)
HITECH Act• Financial incentives for demonstrating “meaningful use”
of EHRs, starting in 2011
• After 2015, financial penalties for failing to demonstrate meaningful use
• 3 meaningful use stages. Stage 2 current focus, stage 3 about to be finalized
• Invest 25.9 to as much as 36.5 billion USD of taxpayer money

MU Stage 2• Provide patients the ability to view online, download
and transmit their health information
• Provide clinical summaries for patients for each office visit
• Provide summary of care record for each transition of care or referral
➔ Export a standardized document
![Page 16: Meaningful Use Stage 2 - etouches · PDF fileMeaningful Use Stage 2 Working With What You Get Pascal Pfiffner, MD, PhD Computational Health Informatics Program Boston Children’s](https://reader031.fdocuments.net/reader031/viewer/2022022503/5ab31b337f8b9a1d168e1e53/html5/thumbnails/16.jpg)
Where are we?• HITECH Act overseen by ONC
• With MU2, export of a “master” document
• SMART funded by ONC
• Develop health information exchange API

CDA Document Structure Example

CDA• CDA = cross-referenced materials
• Ever growing, complex web of documentation
• CDA = multiple approaches for documenting
• template requirements began to diverge
➔ Consolidation harmonized and balloted previous templates into a single IG: C-CDA

Initial Observations• Ambiguous – statements difficult to interpret
• Complex – hard for developers to understand; multiple ways to say the same thing
• Not yet widely and inconsistently implemented
• Not implemented with an automated (programmatic) interface
• Not free to implement or distribute specifications
![Page 21: Meaningful Use Stage 2 - etouches · PDF fileMeaningful Use Stage 2 Working With What You Get Pascal Pfiffner, MD, PhD Computational Health Informatics Program Boston Children’s](https://reader031.fdocuments.net/reader031/viewer/2022022503/5ab31b337f8b9a1d168e1e53/html5/thumbnails/21.jpg)
Still… Let’s Try!
• C-CDA “Receiver”: Expose C-CDA data as JSON
• Minimal data set (DMPAV)
➔ Problem: data fidelity

C-CDA Scorecard
• Check C-CDA for schema, schematron and semantic errors; scored for correctness 0-100%
• 21 vendor-supplied samples: 63% [23, 100]
• Logical and terminology consistency errors
• 12 distinct patterns for telephone numbers

Not Good EnoughNot easy to understand, not adequately
expressive, not consistent enough and not free for innovators and developers

Progress!• FHIR DSTU 2 being finalized
• Growing ecosystem (clinical trials, genomics, ResearchKit, MedRec, …)
• Commitment from major US vendors to provide a SMART / FHIR API in next iterations
• SMART App Gallery with > 30 Apps https://gallery.smarthealthit.org
