Today’s Focus
• Discuss concepts of cognitive workload, variance, shifts and stacking
and how they apply to clinicians
• Review research finding (quickly – not too much academic stuff )
• Examine how technology has impacted clinicians’ cognitive function
• Explore the ways mobile technology is improving cognitive support
and patient care

Cognitive Workload
Workload emerges from the interaction between the:
• Requirements of a task
• Circumstances under which it is performed
• Skills, behaviors, and perceptions of the worker
Level of mental resources required of a person at any one time

Primary observation, semi structured interviews, and surveys of hospital nurses found:
Average nurse -- 8 hr shift
• Average task time 3.1 minutes
• interrupted mid-task eight times per shift
• Completed average 100 tasks
• Cognitive Shift: between patients, on average, every 11 minutes
• 8.4 operational failures
1. Medication problems
2. medical orders
3. Supply issues
4. Staffing issues, such as nurses having to do aides’ or housecleaning’s work
5. Broken or missing equipment

Could EHRs help?
• Small study (n=30) examined cognitive workload needed to complete
printed nursing process versus computerized nursing process from In
• Computerized nursing process contributes to lower cognitive
workload of nurses
• Support system for decision making
• Can enhance nurse safe decision making

"Evaluations of the impact of health IT on
quality and safety show mixed results, however.
The main reasons seems to be a lack of
integration of health IT into clinical workflow
in a way that supports the cognitive work of
the clinician and the workflows among
organizations”

"Documentation does affect the timeliness of care. When a nurse is
ready to give a premeal insulin dose but has to track down the nursing
assistant first to find the patient's glucose level, care is compromised. "
