“Big data is like teenage sex:
everyone talks about it,
nobody really knows how to do it,
everyone thinks everyone else is doing it,
so everyone claims they are doing it...”
-- Dan Ariely @danariely (2013)
Substitute “Big data” with “AI”, “Blockchain”, “IoT”
of your choice.

• Nothing is certain in medicine &
health care
• Large variations exist in patient
presentations, clinical course,
underlying genetic codes, patient &
provider behaviors, biological
responses & social contexts
Why Clinical Judgment Is Still Necessary?
15. 15
• Most diseases are not diagnosed by
diagnostic criteria, but by patterns of
clinical presentation and perceived
likelihood of different diseases given
available information (differential
diagnoses)
• Human is good at pattern
recognition, while machine is good at
logic & computations
Why Clinical Judgment Is Still Necessary?
16. 16
• Machines are (at best) as good as
the input data
–Not everything can be digitized or
digitally acquired
–Not everything digitized is accurate
(“Garbage In, Garbage Out”)
• Experience, context & human touch
matters
Why Clinical Judgment Is Still Necessary?
17. 17
• “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)
Some “Smart” Quotes
18. 18
To treat & to care
for their patients
to their best
abilities, given
limited time &
resources

The Goal of Health Care
The answer is already obvious...
“Health”
“Care”

• Safe
• Timely
• Effective
• Patient-Centered

• Telemedicine (โทรเวชกรรม)
• tele- (to or at a distance) + medicine/health
• “The use of telecommunications technology for
medical diagnostic, monitoring and therapeutic
purposes when distance and/or time separates the
participants.”
• Some use telehealth to indicate care beyond
provided in medical encounters (e.g. health
education, health-related websites)
Telemedicine & Telehealth
Hersh et al (2006)
38. 38
• Store-and-forward telemedicine
– Collect data then transmit them for subsequent interpretation
• Home-based telemedicine
– Used by health professionals to monitor physiology, test results,
images and sounds, usually collected in a patient’s home or a
nursing facility
• Office/hospital-based telemedicine
– Usually real-time clinician-patient interactions that conventionally
would require face-to-face encounters between a patient and a
health professional
3 Main Types of Telemedicine
Hersh et al (2006)
40. 40
• 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)
41. 41
• 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

• 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)

Legal Issues
• Privacy & Security Issues
• Liability due to Risks of Medical Errors
▪ Misdiagnosis
▪ Delayed Diagnosis & Treatment
▪ Miscommunication & Information Reliability
• Legal Compliance
▪ พรบ.สถานพยาบาล, พรบ.วิชาชีพ, พรบ.ยา, พรบ.เครื่องมือ
แพทย์ ฯลฯ
▪ Legal Documentation
61. 61
• Disease-specific & specialty-specific telemedicine
medical practice guidelines (review of evidence &
balancing risk-benefits)
• Medical records documentation guidelines
• Security, privacy & identification/authentication
standards
• Harmonization among regulators
• Professional telemedicine training/certification?
Next Steps on Telemedicine

62. 62
• ความจาเป็นในการแก้ไข พรบ.วิชาชีพเวชกรรม หรือกฎหมาย
อื่นๆ ที่เกี่ยวข้อง หรือออก พรบ. Telemedicine ยังไม่ชัดเจน
แต่มีความพยายามที่จะหารือกันระหว่างหน่วยงานต่างๆ
• Telemedicine Providers เริ่มเปิดให้บริการแล้ว ต้อง
monitor case ร้องเรียน หรือปัญหาที่เกิดขึ้น
