 How can anaesthetist experience the difficulties of
patient care without putting patients at undue risk?
 How can we assess the abilities of anaesthetist as
individuals and teams when each patient is unique?
The answer is
SIMULATIONS
Simulation refers to the artificial
replication of sufficient elements of
a real-world domain to achieve a
stated goal.
This technique well known in the
military, aviation, space flight, and
nuclear power industries.
Uses of simulations
 Team training, as human factor or CRM training
 Training in dynamic plant control
 Training in diagnostic skills

and reliability assessment

recertification of operators

Introduction
 Why is this a valuable tool? Or is it?
 Learners can learn without risk to patient.
 Learning can be focused without regard to patient care
needs/safety/etc.
 Opportunity to repeat lesson/skill to mastery.
 Specific learning opportunities guaranteed.
 Learning can be done at convenient times.
 Performance can be observed/recorded.
Introduction
 Why is simulation important in medical education?
 Problems with clinical teaching
 New technologies for diagnosis/treatment
 Assessing professional competence
 Medical errors and patient safety
 Deliberate practice
Setting of the Simulation Exercise
 Setting introduction (SI): The introduction
delivers general information on how the exercise
will be conducted, logistical information, and
some of the known pitfalls of the course.
 Simulator briefing (SB) or familiarization: They
learn how to use the simulator, what it can and
cannot do, what is “normal” (e.g., normal breath
sounds), and how they can interact with the
environment (e.g., how to call for help, how to
request information about the patient that is not
directly available in the simulation environment).
 Theory input (T): Most exercises have didactic
and theory components on relevant content
information. Sometimes this material is made
available in advance via readings or online
exercises.
 Breaks (B): For complex courses (e.g.,
anesthesia crisis resource management
[ACRM]), breaks are important for socialization
between participants and with instructors. It also
is a venue for informal sharing and storytelling.
 Case briefing (C): In many simulation scenarios,
participants receive a briefing about the upcoming case.
 Simulation scenario (S): Most simulation exercises
involve a scenario that posits a given clinical situation
and challenges to be posed for participants to deal with.
 Debriefing (D): Most scenarios are followed by some form
of debriefing or feedback.
 Ending (E): Especially for multiple-scenario courses,
there may be a separate final session to end the course.
This is an opportunity to summarize issues that were
covered, to address questions, and to consider how best
to apply the principles covered to real patient care.
Site of Simulation
 Dedicated centre - One or more simulators are
used in a dedicated simulation facility, typically
in rooms that can partially or fully replicate, in a
relatively generic fashion, various clinical
environments (e.g., operating room, ICU, labor
and delivery, emergency department).
In-Situ Simulation
In-situ simulation is conducted in an actual clinical
workplace; the simulator “replaces” a patient.
It is especially useful for unusual workplaces that are
difficult to recreate realistically in a simulation center,
such as a catheterization laboratory, computed
tomography scanner, ambulances, or air rescue aircraft.
Most in-situ simulation is performed “mobile” as a
temporary setup, but increasingly in-situ simulation is
established as “residential simulation,” in which a
simulator is permanently installed in a clinical workplace
(e.g., creating a simulation-specific room in the actual
ICU.
Moving Patient Simulation -
The advent of completely portable and wireless
simulators supports exercises in which the
simulated patient can be moved from one clinical
site to another.
Mobile Simulation: “Have Simulator—Will Travel”
Mobile simulation means the simulator and the
audiovisual gear are moved (made mobile)
outside the originating institution for purposes of
the simulation event.
Mobile simulation can be conducted as in-situ
simulation in an actual site of a remote client
institution, by setting up for simulation in
conference rooms or hotel meeting rooms, or by
having a simulation facility built into a truck or
bus.
