                        Market Statistics
   Sudden Cardiac Death (SCD) is the leading single cause
   of death in the U.S. - estimates are 19% of all deaths.-
   460,000 in 2005. 1
   3 to 5% of Americans have atrial fibrillation. 2
   About 5 million people in the United States have heart
   failure, and the number is growing. Each year, another
   550,000 people are diagnosed for the first time. It
   contributes to or causes about 300,000 deaths
   each year. 3
   From 1990 to 2002, 2.25 million pacemakers were
   implanted and 417,780 ICDs were implanted in the U.S. 4
   Estimated total implantable cardiac device market for
   2006 is 9.4 – 9.6 billion dollars. Project growth in the
   market through 2009 is 4 – 8%. 5
   Numerous published clinical studies (COMPANION,
   MADIT, MADIT II, SCDHeft) have shown the efficacy of
   implanted cardiac rhythm management devices.

 Cardiology and EP Workload
   According to Heart Rhythm Society
   studies 1
     Electrophysiology is the fastest growing of all
      cardiovascular disciplines.
     Demands for cardiologist and electrophysiologist
      time is projected to increase through 2020.
   To manage workload EPs and device
   clinics are looking for more efficient ways
   of following patients with implantable
   devices.

      Implantable Cardiac Device Follow-up
           Problems and Opportunities

   Device follow-up load is significant. ICD patients are
   typically followed 4 times a year, and Pacemaker patients 2
   times a year.
   The follow-ups can occur in-clinic or remotely in the home
   healthcare environment.
   EPs follow patients with implantable cardiac devices from
   multiple vendors.
   Each “interrogating” device is vendor proprietary.
   Access to follow-up information often requires
   cardiologists and EPs to use multiple vendor specific
   systems and interfaces, complicating efficiency and quality
   of workflows.
   Aggregation of data into a central EMR or device clinic
   management systems requires manual and paper
   processes.

               IDCO Value Proposition

   Enable management of follow-up
   information in a central system such as an
   EMR, Cardiology Information System or
   Device Clinic Management System
   Improve efficiency and quality of related
   clinical processes
     Single point of access for information
     Automation of current manual processes for data
      collection, aggregation and analysis
     Standardization of workflow processes
     Enabling of analytics

                IDCO Profile Approach

   Rallied domain vendors around a profile that defines a
   standard approach to integrating implantable cardiac
   device follow-up information into a receiving clinic system
   Enabled the needed systems integration by profiling the
   use of standard, domain applicable messaging protocols,
   structures and data semantics
     HL7 Therapeutic Device Domain – Implantable Device
      Cardiac messaging standards
     ISO/IEEE 11073 Point of Care Medical Device
      Communication Standards nomenclature
   Defined actors, transactions and constraints consistent
   with existing and evolving IHE profiles and contexts
     Aligning with future EP Workflow and other related profiles

               EMR Interest in IDCO Profile

   Do any EMR vendors have plans in place to
   support the IDCO profile in future product?
   What will it take to get EMR vendors interested in
   IDCO profile participation for 2008?
   What factors drive potential participation?
   How did EMR vendors decide to participate in
   their current portfolio of supported IHE profiles?
   Who should be contacted within the EMR vendor
   companies to discuss this further?

         EMR Interest continued
   Do EMR vendors need help from IMD device
   vendors to understand the domain and data
   mapping. Would that be useful and positive factor
   in decision making to support the profile?

   If the IDCO message would be extended with
   nontrivial EGM waveforms and annotations data,
   histograms and trends data – what would EMR
   vendors like to parse
     XML document
     Discrete OBX segments
     DICOM objects?

                     HL7 v2 and v3
   Current IDCO profile requires the use of
   an embedded HL7 v3 message structure
   within a HL7 v2 ORU message.
   Current profile has specified an option for
   a standard HL7 v2 ORU message.
   Would EMR vendors be more likely to
   participate if the IDCO profile specified
   compliance using a standard v2 ORU
   message?

   In-Clinic Implants or Follow-ups
     Patients present themselves in-clinic for implantation or
      follow-ups
     Information is collected using vendor specific “programmers”
     Information is sent from interrogation system to a central
      Device Clinic Management System or EMR
   Remote Follow-ups
     Patients devices are interrogated in the home health care
      environment
     Information is collected using vendor specific communication
      devices and systems
     Information is sent from interrogation system to a central
      Device Clinic Management System or EMR
