A traditional approach to learningA traditional approach to learning
Problem #1Problem #1
Just because students learn a task in the classroom doesn’t mean they can demonstrate successful performance during a crisis.
Problem #2Problem #2
Some clinical experiences are so life threatening that students are not going to be involved in the management.
Problem #3Problem #3
Some are so rare that the student may not ever experience the situation until they are in the midst of caring for the patient.
Different simulation Different simulation formatsformats
Patient management problems (paper/pen)
Computerized simulation– Internet-based
Role playing/standardized patientsMannequin-based (e.g., CPR BCLS
trainer)Virtual reality
Why simulation?Why simulation?
Used in many “high reliability” fields– Aviation
– Nuclear power
– Military flight operations
Why simulation?Why simulation?
No risk to patients Many scenarios can be presented,
including uncommon but critical situations in which a rapid response is needed – E.g. malignant hyperthermia 1:40,000 cases
Participants can see the results of their decisions and actions; errors can be allowed to occur and reach their conclusions
Why simulation?Why simulation?
Identical scenarios can be presented to different clinicians or teams
The underlying causes of the situation are known
With mannequin based simulators clinicians can use actual medical equipment– examine limitations in the human-machine
interface
Why simulation?Why simulation?
Re-create clinical environments– Assess interpersonal interactions with other
clinical staff
– Evaluate and improve teamwork, leadership, and communication skills
Why simulation?Why simulation?
Intensive and intrusive recording of the simulation session is feasible– Audiotape
– Videotape
– Physiological monitoring of participants (EEG, ECG, etc.)
Why simulation?Why simulation?
There are no issues of patient confidentiality
Recordings can be preserved for research, performance assessment, or accreditation

Crisis Resource Crisis Resource ManagementManagement
Using all available resources during a crisis to achieve safety and efficiency– Information– Equipment– People
Crisis Resource Crisis Resource ManagementManagement
Error countermeasures– Reduce the frequency of errors– Correct errors– Limit the impact of errors
ResourcesResources
Simulator PLUS operational budget Competency standards
– Who/what are you testing? Content experts
– Set objectives and clinical setting Simulation experts
– Translate objectives and clinical setting into functional simulation scenarios
AV equipment (debriefing)
Limitations of simulationLimitations of simulation
Difficult to demonstrate improved outcome from use of simulation– Adverse events are unusual– Extreme number of potential
confoundersForced to use simulation
performance as surrogate outcome

Simulation is fun for students and teachers
You can use simulation technology as an evaluation tool
Choose the most appropriate tool for achieving educational goals
Remember basics of education, otherwise simulator is an expensive toy
