    • Why Healthcare Isn’t Like Any Others?• Life-or-Death• Many & varied stakeholders• Strong professional values• Evolving standards of care• Fragmented, poorly coordinated Fragmented poorly-coordinated systems• Large, ever-growing & changing body of knowledge• High volume, low resources, little time Source: nj.com

    • Still Many Other Forms of Health IT Health Information Exchange ( g (HIE)) m-Health m Health BiosurveillancePersonal Health Records (PHRs) Telemedicine &Information Retrieval Telehealth Images from Apple Inc., Geekzone.co.nz, Google, PubMed.gov, and American Telecare, Inc.
    • Why Adopting Health IT? “Go paperless” Go paperless “Computerize” Computerize “Get a HIS” “Digital Hospital” Digital Hospital“Have EMR ”“H EMRs” “Modernize” “Share data” Share data
    • Some Quotes• “Don’t implement technology just for technology s sake.” Don t technology’s sake• “Don’t make use of excellent technology. Make excellent use of technology.” (Tangwongsan, Supachai. Personal communication, 2005.)• “Health care IT is not a panacea for all that ails medicine.” (Hersh, 2004)• “We worry, however, that [electronic records] are being touted as a panacea for nearly all the ills of modern medicine.” (Hartzband & Groopman, 2008)
    • Health IT: What’s In A Word?Health GoalInformation  f Value-AddTechnology Tools
    • Dimensions of Quality Healthcare• Safety• Timeliness• Effectiveness• Efficiency• Equity E it• Patient-centeredness at e t ce te ed ess (IOM, 2001)
    • Value of Health IT• Guideline G ideline adherence• Better documentation• Practitioner decision making or process of care• Medication safety• Patient surveillance & monitoring• Patient ed cation/reminder education/reminder
    • Fundamental Theorem of Informatics (Friedman, 2009)
    • Is There A Role for Health IT? (IOM, 2000)
    • Landmark IOM Reports (IOM, 2000) (IOM, 2001)
    • Landmark IOM Reports: Summary• Humans are not perfect and are bound to make errors p• High-light problems in the U.S. health care system that systematically contributes to medical errors and poor quality• Recommends reform that would change how health care works and how technology innovations can help improve quality/safety
    • Why We Need Health IT• Health care is very complex (and inefficient)• Health care is information-rich• Quality of care depends on timely availability & quality of information• Clinical knowledge body is too large• Short time during a visit• Practice guidelines are put “on-the-shelf”• “To err is human”
    • To Err Is Human• Perception errors Source: interaction-dynamics.com

    • What If This Happens in Healthcare?• It already h l d happens.... (Mamede et al., 2010; Croskerry, 2003; Klein, 2005)• What if health IT can help?
    • U.S.’s Efforts on Health IT Adoption ? “...We will make wider use of electronic records and We other health information technology, to help control costs and reduce dangerous medical errors.” President George W. Bush Sixth State of the Union Address, January 31, 2006Source: Wikisource.org Image Source: Wikipedia.org

    • U.S. Adoption of Health IT Ambulatory (Hsiao et al, 2009) Hospitals (Jha et al, 2009) Basic EHRs w/ notes 7.6% Comprehensive EHRs p 1.5% CPOE 17% • U.S. lags behind other Western countries (Schoen et al, 2006;Jha et al, 2008) • Money and misalignment of benefits is the biggest reason
    • We Need “Change” “...we need to upgrade our medical records by switching from a p p to y g paper an electronic system of record keeping...” President Barack Ob P id t B k Obama June 15, 2009
    • The Birth of “Meaningful Use” “...Our recovery plan will invest in  yp electronic health records and new technology  that will reduce errors, bring down costs,  ensure privacy, and save lives. ensure privacy and save lives ” President Barack Obama Address to Joint Session of Congress Address to Joint Session of Congress February 24, 2009Source: WhiteHouse.gov

    • Computerized Physician Order EntryValues• No handwriting!!!• Structured data entry: Completeness clarity Completeness, clarity, fewer mistakes (?)• No transcription errors!• E point for CDSS Entry i f CDSSs• Streamlines workflow, increases efficiency
    • Clinical Decision Support Systems (CDSSs)• The real place where most of the values of health IT can be achieved – Expert systems • Based on artificial intelligence, machine learning, rules, or statistics • Examples: differential diagnoses, treatment options – Alerts & reminders • Based on specified logical conditions • Examples: drug-allergy checks, drug-drug interaction checks, reminders for preventive services or certain actions (e.g. smoking cessation), clinical practice guideline integration – Evidence-based knowledge sources e.g. drug database, literature – Simple UI designed to help clinical decision making
