3. What is EHR Usability ?
• It Means that I can use the electronic health record (EHR)
easily , which achieved when EHR is Effective ,Efficient and
Satisfying for users.
• Usability Means:
EHR is Learnable , Efficient , Memorable , Error Free , and

6. Why Usability is Important ?
• EHR Adoption Barriers [User Centric]
1- Cost of implementation.
2-Security and privacy.
- System is difficult to learn.
- Data Entry time.
- Workflow and information processing problems.

8. key principles that directly impact
EHR usability [HIMSS]
Simplicity means inclusion of only those functionalities,
features and information that is relevant for the user in
the context of completing a task.
Learnability is critical to clinical applications since it is
extremely difficult to provide extensive
training, especially to clinicians whose time is limited.
9. key principles that directly impact
EMR usability - 2
Using themes, navigational models, or icons which users are
already familiar with, or have used somewhere; so that it’s easier
for users to relate.
4- Minimizing Cognitive Load:
In simple terms it means “don't make users think”. This is even
more important for clinicians, as they are almost always
performing under significant time pressure and in environments
bursting with multiple demands for their attention. So provide
them appropriate guidance and instruction about the task in

5- Efficient Interactions:
efficient user interactions to minimize the number of
steps it takes to complete tasks and to provide shortcuts
for use to frequent and/or experienced users.
6- Error Handling and Feedback:
The application should provide appropriate feedback to
the users to minimize the chances of critical error
7- Effective Use of Language:
All language and terminology used in an EMR should be
concise, familiar and meaningful to the end users in the
context of their work.

8- Information Architecture, Data
Visualization and Presentation:
reduce information overload by providing
summary with drill down option wherever
Research shows that 80% of the time, the
information (if well organized) is adequate for
clinical decision making.
12. Usability Challenges
- Administrative, Financial, medical data and clinical
information from different physicians disciplines in
one system which often use different software
• “Good EHRs include the user from the beginning,
from concept development through all stages of
the design cycle until the end,”
• User + designer + developer
13. Usability and ergonomics
14. Usability and Security
- Usability interference with security issues
should be considered under information
security department supervision.
Long and complicated passwords is more secure
than short passwords but on the other hand it
is difficult to be remembered.
15. Usability Organizations involved
• NIST (national institute of standards and
• Private sectors

One size doesn't fits all
Evaluate as a :
