Why Are Healthcare IT Why Are Healthcare IT Standards Important?Standards Important?
Step #2 toward Crossing the Quality Chasm: “. . . making effective use of information technologies to automate clinical information and make it readily accessible to patients and all members of the care team. An improved information infrastructure is needed to establish effective and timely communication among clinicians and between patients and clinicians.”
- IOM Report, 2001

What IT Standards EnableWhat IT Standards Enable
Greater efficiency and cost savings
The ability to make best of breed purchasing decisions
Better and more timely communication of medical information
Improved patient safety
Data for outcomes analysis and decision support
The potential to build a system of evidence-based medicine
The potential to develop a truly comprehensive and portable EHR
So why haven’t standards solved all of
healthcare’s interoperability issues?

NAHIT Standards DirectoryNAHIT Standards Directory
“ . . . Since launching a beta version for members only in April, the Alliance has expanded the directory to include 850 voluntary and mandatory standards and electronic links to more than 200 standards development organizations.” The great thing about standards is that there are so many to choose from

Standards Alone Are Not EnoughStandards Alone Are Not EnoughToo many standards No clear domain boundaries No clear mapping of information flow across
boundaries Too much generality and ambiguity Version incompatibilities Vendor proprietary interests Complexity!!
We need standards for how to
implement standards!

Connecting Standards to CareConnecting Standards to Care
Care providers must work with industry to coordinate the implementation of standards to meet their needs Care providers need to identify the key
interoperability problems they face Drive industry to develop and make available
standards-based solutions Implementers need to follow common guidelines in
purchasing and integrating systems that deliver these solutions

IHE Grows from DICOM ExperienceIHE Grows from DICOM Experience
Integrating the Healthcare Enterprise: an initiative by healthcare professionals and
industry to improve the way computer systems in healthcare share information
promotes the coordinated use of established standards such as DICOM and HL7 to address specific clinical needs
leads to systems that communicate better, are easier to implement, and enable care providers to use information more effectively

IHE ProcessIHE ProcessUsers identify desired functionalities that require coordination and communication among multiple systems
E.g., departmental workflow, single sign-on, cross-departmental sharing of documents and information
Find and document standards-based transactions among systems to achieve desired functionality
Apply necessary constraints to eliminate useless wiggle room
Provide process and tools to encourage vendors to implement
MESA software test tools Connectathon interoperability testing event
Provide tools and education to help users acquire and integrate systems using these solutions
Connectathon results and public demonstrations Integration statements RFP toolkit (soon)
