Interaction features categorized as fast, fit, feedback, forgiveness, and flexible design

Interaction (Function)

Fast

Provide timely feedback

Reduce the amount of time the user is required to interact with the  CDSS

Fit

Minimize cognitive load (reduce the number of mouse clicks and  amount of free-text typing; use selection tools, sort options)

Minimize cognitive load (request information from the provider only when necessary; reduce manual input of values)

Reduce screens to facilitate navigation and to promote efficient  interactions

Automatically pull data from the EHR/integrate into the charting  system

Navigate to appropriate locations

Initiate intervention and take advantage of interactivity (system provides corollary action)

Provide a route to get to provider-specific info

Adapt its behavior according to a subset of relevant actions taken by clinicians

Automate alerting

Request documentation of reasons for not following system  recommendations

Forgiveness

Flexible design

Involve the patient

Utilize adaptive design and feedback

Provide an indication for all professionals of the availability of  information; the designers may choose the most appropriate  way of indicating the information in the interface

Give access upon request to extended information (eg, justification  for the rule, attached scientific documentation) that should be  structured depending on the user profile
