• Life-or-Death
• Difficult to automate human decisions
– Nature of business
– Many & varied stakeholders
– Evolving standards of care
• Fragmented, poorly-coordinated systems
• Large, ever-growing & changing body of
knowledge
• High volume, low resources, little time

• “Don’t implement technology just for
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)

Biomedical & Health Informatics
• “[T]he field that is concerned with the
optimal use of information, often
aided by the use of technology, to
improve individual health, health care,
public health, and biomedical
research” (Hersh, 2009)

Being “Smart” in Healthcare
33. 33
• Efficient
–Faster care
–Time & cost savings
–Reducing unnecessary tests
• Equitable
–Access to providers & knowledge
• Patient-Centered
–Empowerment & better self-care
Being “Smart” in Healthcare
35. 35
• To Err is Human (IOM, 2000) reported
that:
– 44,000 to 98,000 people die in U.S.
hospitals each year as a result of
preventable medical mistakes
– Mistakes cost U.S. hospitals $17 billion to
$29 billion yearly
– Individual errors are not the main problem
– Faulty systems, processes, and other
conditions lead to preventable errors
Patient Safety
36. 36
Summary of These Reports
• Humans are not perfect and are bound to
make errors
• Highlight problems in U.S. health care
system that systematically contributes to
medical errors and poor quality
• Recommends reform
• Health IT plays a role in improving patient
safety
37. 37
• Medication Errors
–Drug Allergies
–Drug Interactions
• Ineffective or inappropriate treatment
• Redundant orders
• Failure to follow clinical practice guidelines

Wrong Assumption
Correct Assumption
64. • Current Trends
–Change from using telehealth to increase access to
health care to providing convenience and reducing
cost
–Expansion of telehealth to chronic conditions
–Migration of telehealth from hospitals and clinics to
home and mobile devices
State of TeleHealth
Dorsey & Topol (2015)
65. • Limitations of Telehealth
–Reimbursement
• Limited & fragmented insurance coverage of telehealth
• Potential for excess health care utilization
–Clinical issues
• Patient-physician relationship
• Quality of physical examination
• Quality of care with remote visits than with in-person
visits

Dorsey & Topol (2015)
66. Dorsey & Topol (2015)
• Limitations of Telehealth
–Clinical issues (continued)
•Potential for abuse (e.g. overprescribing of
narcotics)
•Fragmentation of care among multiple providers
–Legal issues (e.g., state licensure, liability)
–Social issues (digital divide)
State of TeleHealth
67. Legal Issues
• Privacy & Security Issues
• Liability due to Risks of Medical Errors
Misdiagnosis
Delayed Diagnosis & Treatment
Miscommunication & Information Reliability
• Legal Compliance

69. Medical Practice Issues
• Benefits of Telemedicine
–Patient accessibility/Convenience/Engagement
–Clinical outcomes (evidence still needed in most
cases)
–Reduced patient waiting time at the hospital
–Improved logistics (Medications, Materials, Patients)
–More longitudinal data for patient care
70. Medical Practice Issues
• Risks of Telemedicine
– Data accuracy, reliability & timeliness
– Limitations of technology in medical practice
– Diagnostic errors
– Treatment delays
– Miscommunication / Unrealistic expectations
– Doctor-patient relationship & trust
– Abuse
– Provider burden
– Legal compliance
