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)

  23. 23. 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”
