2 1 Why Are Standards Important?

3 2 Why Are Healthcare IT 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

4 3 What 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 havent standards solved all of healthcares interoperability issues?

5 4 ER The Standards Archipelago ADT/ HIS CIS EKG Cath Lab Lab OR RIS PACS Mods Pharm Islands of data across the healthcare enterprise HL7 2.4 DICOM POC Devices IEEE – POCT HL7 2.1 NCPDP Billing X12/ICD9 DICOM

6 5 NAHIT 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 -Old Wisecrack

7 6 Standards Alone Are Not Enough Too 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!

8 7 Connecting 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

9 8 ACR-NEMA Becomes DICOM: c Demonstrations drive awareness and demand for standards-based solutions

10 9 IHE 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

11 10 IHE Process Users 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)

12 11 IHE Participants Societies Representing Healthcare Segments RSNA, HIMSS, ACC, ACCE, … Users Clinicians, Medical Staff, Administrators, CIOs, … Consultants Information Systems Vendors Imaging Systems Vendors Standards Development Organizations (SDOs) DICOM, HL7, ASTM, …
