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)
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”

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
American Recovery & Reinvestment Act • Contains HITECH Act ( (Health Information Technology for Economic and gy Clinical Health Act) • ~ 20 billion dollars for Health IT investments • Incentives & penalties for providers

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
