2. Recap from Part 1
Information is everywhere in medicine
Computerizing health care is difficult because of its
complexity
Health IT has a role because “To Err Is Human”
Health IT is just a tool. Whether it improves patient
care and outcomes depends on its design and
implementation

11. Functions that Should Be Part of EHR Systems
Computerized Medication Order Entry
Computerized Laboratory Order Entry
Computerized Laboratory Results
Physician Notes

Medication Lists
Discharge Summaries
Diagnostic Test Results
Radiologic Reports
11 (IOM, 2003; Blumenthal et al, 2006)
13. Computerized Physician Order Entry (CPOE)
Values
No handwriting!!!
Structured data entry: Completeness, clarity,
fewer mistakes (?)
No transcription errors!
Entry point for CDSSs
Streamlines workflow, increases efficiency

14. Clinical Decision Support Systems (CDSSs)
The real place where most of the
values of health IT can be achieved
Expert systems
Based on artificial intelligence,
machine learning, rules, or
statistics
Examples: differential diagnoses,
(Shortliffe, 1976) treatment options
14
15. Clinical Decision Support Systems (CDSSs)
Alerts & reminders
Based on specified logical conditions
Examples:
Drug‐allergy checks
Drug‐drug interaction checks
Drug‐disease checks
Drug‐lab checks
Drug‐formulary checks
Reminders for preventive services or certain actions
(e.g. smoking cessation)
Clinical practice guideline integration
15
17. Clinical Decision Support Systems (CDSSs)
Evidence‐based knowledge sources e.g. drug
database, literature
Simple UI designed to help clinical decision making

30. Unintended Consequences of Health IT
Errors in the process of entering and retrieving information
A human‐computer interface that is not suitable for a highly
interruptive use context
Causing cognitive overload by overemphasizing structured and
“complete” information entry or retrieval
Structure
Fragmentation
Overcompleteness
Ash et al. (2004)

31. Unintended Consequences of Health IT
Errors in the communication and coordination process
Misrepresenting collective, interactive work as a linear, clearcut,
and predictable workflow
Inflexibility
Urgency
Workarounds
Transfers of patients
Misrepresenting communication as information transfer
Loss of communication
Loss of feedback
Decision support overload
Catching errors

Physician & non‐physician user involvement
Attention to workflow changes
Well‐executed project management

37
39. Health IT Successes & Failures
What success is
Different ideas and definitions of success
Need more understanding of different stakeholder
views & more longitudinal and qualitative studies of
failure
What makes it so hard
Communication, Workflow, & Quality
Difficulties of communicating across different
groups makes it harder to identify requirements and
understand workflow
39 Kaplan & Harris‐Salamone (2009)
40. Health IT Successes & Failures
What We Know—Lessons from Experience
Provide incentives, remove disincentives
Identify and mitigate risks
Allow resources and time for training, exposure, and
learning to input data
Learn from the past and from others
40 Kaplan & Harris‐Salamone (2009)
45. Considerations for a successful
implementation of CPOE
Considerations
Motivation for implementation
CPOE vision, leadership, and personnel
Costs

46. Minimizing MD’s Change Resistance
Involve physician champions
Create a sense of ownership through
communications & involvement
Understand their values
Be attentive to climate in the organization
Provide adequate training & support
46 Ash et al. (2003)
47. Reasons for User Involvement
Better understanding of needs & requirements
Leveraging user expertise about their tasks & how
organization functions
Assess importance of specific features for prioritization
Users better understand project, develop realistic
expectations
Venues for negotiation, conflict resolution
Sense of ownership

52. Summary
Health IT applications vary in their “mechanisms of
actions” (improvements in outcomes).
Health IT can lead to “unintended consequences”
and bad outcomes if poorly designed,
implemented, or managed.
Realizing benefits of health IT depends on critical
success factors, mostly management aspects
(including change management, project
management)
