  • My Health e Vet is a web-based personal health record portal which includes access to patient education, VA benefits and resources, a comprehensive personal health journal, and online prescription refills. Collaborating agencies include the Department of Defense; National Institutes of Health; Centers for Disease Control; and the American Health Information Community. The My Health e Vet Program provides America’s veterans with secure universal access to their personal health information in order to improve their health care. My Health e Vet is based on the core belief that knowledgeable patients are better able to make informed health care choices, stay healthy, and seek services when they need them. The program enables and supports veterans by making them more empowered health care consumers. Quality, access, value, and patient satisfaction are improved through the development of a collaborative health care tool. My Health e Vet uses innovative technology to complement the delivery of traditional health care services. The program meets the President’s charge to agencies to use technology to its fullest potential to provide services and information that are centered on citizen groups. My Health e Vet furthers the aim of electronic government (E-Gov) by exemplifying citizen-centric, interactive tools that the government can provide to veterans and their relatives. The My Health e Vet Program meets the needs of veterans, families, and caregivers by providing secure and universal access to comprehensive health and medical information that is crucial to patient care. This access is an important patient safety factor for high quality care, and it becomes critically important during emergencies ranging from an individual situation to a natural disaster or some other catastrophe. My Health e Vet allows Veterans and their families to collaborate in the management of their personal healthcare through innovative capabilities: online viewing of Personal Health Records (PHR); filling prescriptions; and management of medical history. This collaboration serves to map the care accessible online to existing clinical practices within VA hospitals. The result is improved quality and greater satisfaction of care. Additionally, My Health e Vet assists both long-term veterans and new veterans transitioning from active duty by integrating with the Department of Defense. An Executive Order issued on August 22, 2006 directed agencies to “ ensure that health care programs administered or sponsored by the Federal Government promote quality and efficient delivery of health care through the use of health information technology.” As a complement to VA’s award-winning fully Electronic Medical Record, the My Health e Vet Personal Health Record enables veterans to more fully participate as partners with physicians in their health care. My Health e V e t is part of VA Strategic Initiative 1.2 that uses the PHR to enhance the veteran/provider partnership and optimize veteran health. My Health e Vet goals are: Using MHV to support the dissemination of standard patient education and clinical business practices. Using Information Technology to increase convenience and response time for veterans requesting VHA services. Increasing communication / collaboration between veterans and clinicians. Enabling veterans to consolidate and monitor their own health records and share this information with non-VA clinicians and others involved in their care. Empowering the patient to control what information is accessible by others. Collaboration with DoD eHealth portal TriCareONLINE to maximize VA and DoD resources and achieve a seamless transition from military to civilian life.
  • HL7 Data can be real time messages or batch files. HL7 customization is required. Ex. Up stream from radiology - Registering, Format can be standards based or proprietary. Proprietary can be defined by the hospital, organization, or by the vendor. i.e. patient sensitivity. DICOM- storage is static BLOBs (binary large objects) that never get updated What make objects different from messages? Persistence, Stewardship, Authentication, Context, Wholeness, Human Readability.
  • Hopefully this will make it easier to start reading and using the DICOM standard
  • CDRH regulatory powers include the authority to require certain technical reports from the manufacturers or importers of regulated products, to require that radiation-emitting products meet mandatory safety performance standards, to declare regulated products defective, and to order the recall of defective or noncompliant products. The CDRH also conducts limited amounts of direct product testing.
  • Electronic Medical Record: An electronic record of health-related information on an individual that can be created, gathered, managed, and consulted by authorized clinicians and staff within one healthcare organization.
  • Will a standard last over two thousand years?
  • Will a standard last over two thousand years?
  • The VA healthcare enterprise consists of 157 medical centers and over 850 outpatient clinics. The VA is installing approximately 140 retinal camera systems for its diabetic retinopathy surveillance project. In order to be convenient for the patient, the examinations are performed at sites chosen to minimize travel. The VA is also establishing approximately 20 reading centers around the country for diagnosis. A reading center can serve any acquisition site, not just the ones in its region.
  • Remember the song by Chicago, “Old Days” good times I’ll Remember. I don’t think they were singing about radiology. Do you remember how difficult film work flow was? Here is a typical flow, 59 steps involving 11 hospital staff.

    • Compare with Medicare and the medical consumer price index have remained high and are increasing.
    • GRAPHIC SOURCE: The Washington Post, April 10, 2007
  • Standards last a long time
    • The major design feature of what is arguably the world's most advanced transportation system was determined over two thousand years ago by the width of a horse!
    • The Space Shuttle engineers who designed the Solid Rocket Boosters was shipped by train from the factory to the launch site
  • Standards last a long time
    • The US standard railroad width derives via Europe standard
    • This is traced back to original specification of the Imperial Roman war chariot
  • Technology Lifetime Standards (DICOM, HL7, IHE, SNIA…) 25- 50 years Infrastructure (IP, SAN,…) 10- 20 years Programming Languages (PL/1, Pascal, C, C++, Java, …) 5-10 years Software (data formats, compatibility, …) 2-5 years Hardware (Network cards, video cards, processors, …) 1-2 years Shapiro, IBM
  • Volume, Value and Velocity
    • Volume of Data
      • Reference data is growing exponentially and is being stored for long periods of time.
    • Value of Information
      • Image data is actively referenced, and must be stored and protected for life to meet clinical and regulatory requirements.
    • Velocity of Change
      • Address the demands for increased storage and higher performance.
  • Consistent Integration
    • VistA was awarded with both an Innovations in Government Award and a IHE User Success Story
    • One interface for over 400 different models of instruments!
    • Consistency & Interoperability throughout the US
  • Patient Safety: Current Statistics
    • One in five Americans (22%) report that they or a family member have experienced a medical error of some kind.
    • Nationally, this translates into an estimated 22.8 million people with at least one family member who experienced a mistake in a doctor's office or hospital.
    Reference - http:// www.patientsafetyfocus.com / accessed May 2008
    • Deaths and costs continue to rise. In their fifth annual Patient Safety in American Hospitals Study , Health Grades Inc. , cites that errors in treatment resulted in 238,337 potentially preventable deaths of Medicare patients in the US, costing $8.8 billion.
    • HealthGrades Inc. analyzed over 41 million patient records for the study and found that approximately 3 percent of all Medicare patients suffered from some medical error- - which equates to about 1.1 million Patient Safety Incidents (PSIs) from 2004-2006. In the report, Health Grades describes medical errors as “the failure of a planned action to be completed as intended or the use of a wrong plan to achieve an aim…[including] problems in practice, products, procedures, and systems."
    • There were 270,491 actual in hospital deaths that occurred among patients who developed one or more of 16 PSIs and the report states, "Using previous research, we calculated that 238,337 were attributable to patient safety incidents and potentially preventable."
    • “ Issues arising from badly designed and poorly integrated HIT systems harm or kill more patients every year than do medications and medical devices yet there is absolutely no control or regulation over them”
    Quote Reference: Duke University Health System CIO Asif Ahmad Computerworld, April 28, 2008
  • US Population Dose Ref: Dr. S. Balter, Columbia University, Radiation Dose Data Management, February 2008
  • Radiation Overexposure
    • FDA CDRH case study of radiation therapy overexposure resulting in death
    • Contributing factors include lack of clinic verification, no method for entering data into software, interpretation of data by the software
    • Vendors now have proprietary solutions
    • Reference: FDA Safety Assurance Case Workshop, February 21, 2008
  • Getting Connected for Patient Safety
    • “Many improvements in patient safety and healthcare efficiency require systems solutions that cannot be implemented due to the lack of interoperability”

  • Law & Order Analogy
  • Why Healthcare IT Standards?
    • HIT Standards last much longer than hardware and software systems
    • Standards based solutions provide a higher level of effectiveness and efficiencies
    • Medical Errors contribute to more than 100K US deaths/yr
    • Interoperability and proprietary are often mutually exclusive
    • HIT Standards based solutions provide lower costs, more flexibility and enable better patient care
