3. 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)
• “[T]he application of the science of information
as data plus meaning to problems of
biomedical interest” (Bernstam et al, 2010)

5. Informatics As A Field
5 Shortliffe (2002)

6. Because Information is Everywhere...

7. Emergency Departments (ED)
• Prone to errors because of
– Urgent nature
– Limited & at times unreliable patient history
– Time & resource constraints
• Scale & unpredictability of mass casualties &
disasters make it worse
• 32% of ED visits had information gaps which can
lead to prolonged ED stay (Stiell et al., 2003)
7

8. Informatics Roles in Emergency Medicine
• Provide patient information critical to care
• Information improves quality & efficiency of care
in ED, at least for some conditions
(e.g., Theera-Ampornpunt et al., 2009; Overhage et al., 2002;
Connelly et al., 2012)
• Role of health information exchange (HIE)
highlighted
• IT as transformational tools that improve care
processes

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

10. Dimensions of Quality Healthcare
• Safety
• Timeliness
• Effectiveness
• Efficiency
• Equity
• Patient-centeredness
10 IOM (2001)

11. Better Information Delivery Improves
• Safety (prevent allergies)
• Timeliness (have access to information early)
• Effectiveness (information for decision-making)
• Efficiency (prevent unnecessary/redundant lab)
• Equity
• Patient-centeredness
11

12. IT as Tools for Process Redesign
• Safety (no handwriting!!, allergies/DI alerts)
• Timeliness (faster internal processes)
• Effectiveness (CDSS alerts & reminders)
• Efficiency (faster care, better patient flow, better
bed management)
12

13. Because... “To Err Is Human”

14. To Err Is Human
• Lack of Attention

16. What If This Happens in Healthcare?
• It already happens....
(Mamede et al., 2010; Croskerry, 2003; Klein, 2005)
• What if health IT can help?

21. Clinical Decision Support Systems (CDSSs)
• CDSS as a replacement or supplement of
clinicians?
– The demise of the “Greek Oracle” model (Miller & Masarie, 1990)
The “Greek Oracle” Model
The “Fundamental Theorem”
21 Friedman (2009)

22. Electronic Health Records (EHRs)
• Electronic documentation of patient care by
providers
• Sometimes defined as longitudinal records of a
patient’s health care
22

23. Electronic Health Record (EHR) Systems
• Are they just electronic documentation?
History Diag- Treat-
...
& PE nosis ments
• Or do they have some other values?
23

24. Benefits of Health IT
• Literature suggests improvement in health care
through
– Guideline adherence (Shiffman et al, 1999;Chaudhry et al, 2006)
– Better documentation (Shiffman et al, 1999)
– Practitioner decision making or process of care
(Balas et al, 1996;Kaushal et al, 2003;Garg et al, 2005)
– Medication safety (Kaushal et al, 2003;Chaudhry et al, 2006;van
Rosse et al, 2009)
– Patient surveillance & monitoring (Chaudhry et al, 2006)
– Patient education/reminder (Balas et al, 1996)
– Cost savings and better financial performance
(Parente & Dunbar, 2001;Chaudhry et al, 2006;Amarasingham et al,
2009;Borzekowski, 2009)

25. Functions that Should be Part of EHR Systems
• Computerized Medication Order Entry
• Computerized Laboratory Order Entry
• Computerized Laboratory Results
• Physician Notes
• Patient Demographics
• Problem Lists
• Medication Lists
• Discharge Summaries
• Diagnostic Test Results
• Radiologic Reports
25
IOM (2003), Blumenthal et al (2006)

26. Health Information Exchange (HIE)
Government
Hospital A Hospital B
Clinic C

27. Personal Health Records (PHRs)
• “An electronic application through which individuals can
access, manage and share their health information,
and that of others for whom they are authorized, in a
private, secure, and confidential environment.” (Markle
Foundation, 2003)
• “A PHR includes health information managed by the
individual... This can be contrasted with the clinician’s
record of patient encounter–related information [a
paperchart or EHR], which is managed by the clinician
and/or health care institution.” (Tang et al., 2006)
27

28. Types of PHRs
• Patient portal from a provider’s EHRs (“tethered” PHRs)
• Online PHRs
– Stand-alone
– Can be integrated with EHRs from multiple providers
(unidirectional/bidirectional data sharing)
• Stand-alone PHRs
– PC-based applications
– USB Drive
– CD-ROM or other data storage devices
– Paper
28

29. Use Cases of PHRs
• Data entry/update by patients
• Data retrieval by providers
– With patient’s consent
– “Break-the-glass” emergency access
• Data update from EHRs
• Privacy settings
• Personalized patient education & reminders
• Communications with providers
29

30. Mobile Health (mHealth)
• Exponential increase in mobile devices
• Technology penetration in rural, underserved
settings
• Democratization of information access
• Roles of social media
30

31. mHealth & Social Media in Disaster Management
• Communication, coordination & collaboration
tools for relief workers, disaster managers,
victims
• Used heavily in
– Haiti’s 2010 earthquake
– Japan’s 2011 earthquake & tsunami
– Thailand’s 2011 record flooding
31

32. What Happened in Thailand in 2011?
• Unusually heavy rainfalls
• Flooding began in the north, continued
downstream to Gulf of Thailand
• Dams insufficient capacity to handle the
amount of water
• Severe flooding in ~ 1/3 of Thailand
• Record flooding in 50 years

33. Impact
• 800+ deaths
• Many millions affected
• Residences, businesses,
factories & industrial complexes,
hospitals, etc. all affected
• Historic sites damaged
• Economic impact: (est.) $46
billion (World Bank)
