Got Cognitive Load?
Do you feel…TiredOverwhelmedBurned OutDisengagedRushedShort TemperLack of enthusiasm
Ask you doctor…
•Cognitive Load is the aggregate mental effort required in problem solving and learning.
Working Memory Working Memory is the space you have to do that work.It is finite and fixed.

Cognitive Load is the aggregate mental effort required in problem solving and learning.
Intrinsic Cognitive Load
The inherent complexity of the task.
Interactivity of elements.

IntrinsicCognitive Load
Minimal Moderate Heavy
Medical Problem Solving?
= Intrinsic Load + Extraneous Load + Germaine Load
Extraneous Cognitive Load
manner in which information is presented to solver/learner
it is imposed by mental activities that can have a negative effect on learning if not designed appropriately. Extraneous load can interfere with the construction or automation of schemas.
a round plane figure whose
boundary consists of points
equidistant from a fixed point.
Cognitive Load is the aggregate mental effort required in problem solving and learning.
= Intrinsic Load + Extraneous Load + Germaine Load
What’s Missing?
“Germaine” Cognitive Load-
Learning
Load imposed by constructing new schemas and automating them…Learning! This is germane cognitive load.
Cognitive Load is the aggregate mental effort required in problem solving and learning.
= Intrinsic Load + Extraneous Load + Germaine Load

Getting started
Reduce Incidental Processing
Basic layout – Simple
• Structure• Predictable, Consistent, Minimize scanning
• Colors/Symbols• Meaningful, Consistent
• Content • Increase Signal to Noise Ratio, Eliminate non essential information
Reduce Incidental Processing
Basic layout – Simple
• Presentation• Consistent with the providers Mental Model/schema
• Flow• Consistent with clinical thinking, Return me where I left off, Predict
and make available 3 next most common actions
• *Make documentation a byproduct of the clinical work
example
Oh yeah, also 800x600 Resolution is so 1999
Reducing Extrinsic Cognitive Load
• Presentation of information in format and structure consistent with how providers see the world (schema).
Remember our card game?
Examples
• Problems• Last Assessment
• Comments
• Last Assessment Date
• Previous HPI/Plan
• Flowsheets-Clinical Clusters
Reducing Extrinsic Cognitive Load
• Structured documentation/data collection- Good templates, bad templates• My office phone number
• (1)5 (2)1 (3)0 (4)2 (5)3 (6)0 (7)2 (8)3 (9)7 (10)2
• (510) 230-2372
• If you want discrete data captured, you must make it easy
• example
Reducing Extrinsic Cognitive Load
• Make it easy to offload working memory when appropriate• Update in family hx, surgical hx.
• Refill medication
• Future reminder
• Flag task to MA
• Right tool for the job- quick visit
• Facilitate next steps
• examples

•Cognitive Load is the aggregate mental effort required in problem solving and learning.
Working MemoryWorking memory is finite and is the rate limiting step
Help the doctor help the patient Shrink Intrinsic Load by breaking down tasks Shrink Extrinsic Load by addressing presentation of information Limit Learning (Germaine) Load by avoiding “education” during visits
