Why Adopting Health IT?
“To Computerize”“To Go paperless”
“Digital Hospital”
“To Modernize”
“To Get a HIS”
“To Have EMRs”
“To Share data”

“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)

Is There A Role for Health IT?

28
Humans are not perfect and are bound to make errors
Highlight 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

29
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”

• U.S. lags behind other Western countries (Schoen et al, 2006;Jha et al, 2008)
• Money and misalignment of benefits is the biggest reason

Vision เป็นโรงพยาบาลชั้นนําของภูมิภาคเอเชียทีม่ีความเป็นเลศิในด้านบริการ การศึกษา และวิจัย
Current IT Environment เป็น รพ.แรกๆ ที่มี HIS ซึ่งพัฒนาเอง และ
ต่อยอดจาก MPI, ADT ไปสู่ CPOE (แต่ยังขาด advanced CDSS) ระบบ HIS เข้ากับ workflow ของ รพ. เป็นอย่างดี
ปัจจุบัน ระบบ HIS ยังใช้เทคโนโลยีเดียวกับช่วงที่พัฒนาใหม่ๆ (20 ปีก่อน) เป็นหลัก มีการนําเทคโนโลยีใหม่ๆ มาใช้อย่างช้าๆ
รพ.เอกชน 200 เตียงVision เป็นโรงพยาบาล High Tech

บุคลากรมีอายุเฉลีย่ 42 ปี (range 20-65)
แผนก IT มีทั้งบุคลากรใหม่และทีเ่คยพัฒนาระบบ HIS ตั้งแต่แรกเริ่ม
แพทย์มีความเป็นตัวของตัวเองสูง, มักทํางานเอกชนด้วย, มี turn-over rate สูง
พยาบาลและวิชาชีพอื่นมักมองว่าแพทย์คืออภิสทิธิ์ชน และมีเรื่องถกเถียงกันบ่อยๆ
รพ.เอกชน 200 เตียง บุคลากรมีอายุเฉลีย่ 32 ปี
(range 20-57)
แผนก IT เข้มแข็ง
แพทย์ไม่ค่อยมี interaction กับ
บุคลากรอื่น, รายได้เป็นแรงดึงดูดหลัก
ผู้บริหารได้รับการยอมรับจากบุคลากร
ทุกวิชาชีพว่ามีวิสัยทัศน์และบริหารงาน
ได้ดี
