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 informationas data plus meaning to problems of biomedical interest” (Bernstam et al, 2010)

Informatics As A Field
Shortliffe (2002)

Because Information is Everywhere...
![Page 7: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/7.jpg)

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)
![Page 8: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/8.jpg)

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
![Page 9: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/9.jpg)

Why Adopting Health IT?
“To Computerize”“To Go paperless”
“Digital Hospital”
“To Modernize”
“To Get a HIS”
“To Have EMRs”
“To Share data”
![Page 10: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/10.jpg)

Dimensions of Quality Healthcare
• Safety• Timeliness• Effectiveness• Efficiency• Equity• Patient-centeredness
IOM (2001)
![Page 11: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/11.jpg)
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
![Page 12: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/12.jpg)
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)
![Page 13: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/13.jpg)

Because... “To Err Is Human”

To Err Is Human
• Lack of Attention

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

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”
Friedman (2009)
![Page 22: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/22.jpg)
22
• Electronic documentation of patient care by providers
• Sometimes defined as longitudinal records of a patient’s health care
Electronic Health Records (EHRs)
![Page 23: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/23.jpg)

• Are they just electronic documentation?
• Or do they have some other values?

24
• 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;vanRosse 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)

• 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
Functions that Should be Part of EHR Systems

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.” (MarkleFoundation, 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)
![Page 28: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/28.jpg)
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
![Page 29: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/29.jpg)
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
![Page 30: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/30.jpg)
30
Mobile Health (mHealth)
• Exponential increase in mobile devices• Technology penetration in rural, underserved
settings• Democratization of information access• Roles of social media
![Page 31: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/31.jpg)
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
![Page 32: Informatics in Emergency Medicine: A Brief Introduction (Presentation)](https://reader034.fdocuments.us/reader034/viewer/2022052310/554b3249b4c905ce088b50ad/html5/thumbnails/32.jpg)
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

Conclusion• Health IT and informatics
– Provide information for high quality emergency care– Have potential to transform care processes (not just
computerizing patient care)– Come in various forms (EHRs, CDSS, HIE, PHRs,
mHealth, biosurveillance)
• Increasing roles of health IT and informatics for tomorrow’s emergency and disaster management
• New innovations & new uses of IT discovered through every emergency situation
