Q

5 adopter categories according to Diffusion of Innovation (DOI)

A
  1. Innovators
  2. Early Adopters - do not need info to convince them to change
  3. Early Majority - need to see evidence the innovation works
  4. Late Majority - skeptical of change and will only adopt after it has been tried by the majority
  5. Laggards

26
Q

Difference between leading vs lagging indicators

A

Leading indicators look FORWARD to predicting future success and tend to be INPUT oriented (e.g. number of open ambulatory encounters)

Lagging indicators LOOK BACK to evaluate past success and therefore more OUTPUT oriented (e.g. revenue collected)

27
Q

What is a technology-induced error?

A

Error that result from the complex interaction of health information systems and end users, when systems are used in complex healthcare settings.

28

A

Complex adaptive systems

AKA Complex Theory or Systems Theory

33
Q

5 attributes of system usability

A
  1. Learnability: system should be relatively easy to learn
  2. Efficiency: an experienced user can attain a high level of productivity
  3. Memorability: features supported by the system should be easy to retain once learned
  4. Errors: system should be designed to minimize errors and support error detection and
  5. Satisfaction: the user experience should be subjectively satisfying
34
Q

What is Grounded Theory?

A
  • Ethnographic workflow analysis method
  • Uses inductive analysis (analysis occurs in parallel with data collection)
  • Data broken down into codes –> codes combined to categories
  • Helpful in uncovering hidden triggers or cultural taboos
35
Q

What is PRECEDE-PROCEED?

A

Example of change theory

PRECEDE = diagnostic phase (assessment of organization’s readiness for change)

PROCEED = evaluation phase

36
Q

What is Bridges’ Transition Theory
