Introduction

This document is written to help smooth the development of a patient / scenario for our human patient simulator. “Story-boarding” is a common practice in movie making and computer multimedia design. Story boarding involves scripting out on paper what you would like the final product to look like. We will use the story-boarding process in simulation module design and development.

 

We have found this process to be quite important in the simulation development. The following form was designed to help in the storyboarding process.

 

Template

The first component of the template is the “Case Information”. This includes the educational rationale behind the simulation module, the reason for the simulation module, the objectives, the target audience, the developer’s names, the equipment and support components needed, etc.

 

The next part of the template, “Equipment and Supporting Objects” requires you to think through the equipment and multimedia elements needed in support of the simulation.

 

The next component of the template is the “Simulation Scenario Set-Up”. This is the information given to the learner in the debrief room (or at bedside) before they begin the simulation. On the latter part of this page, one should include information destined specifically for the facilitator, but not to be viewed by the learner. 

 

There are actually two components to any simulation: the patient and the scenario. For instance we may run a Malignant Hyperthermia scenario on a “healthy” patient or a patient with severe co-morbidity.

 

The scenario represents how the simulation plays out over time. Each scenario should be broken down into mini-scenarios (called “states”). Each state represents a progression of the simulation. Stepping  from state to state is caused by a “trigger.”. Triggers may be time, drugs, or specific learner actions. For instance, our malignant hyperthermia scenario might be broken down into baseline, mild, moderate, severe, and resolution states. Use of volatile agent in the simulation would “trigger” the mild MH state. Time might cause the trigger between mild, moderate, and severe MH. Finally, the use of Dantrolene in the simulation would trigger resolution state. Failure to give Dantrolene would strand the simulation in the “severe” MH state which would eventually lead to “death”.

 

The next component is the “Patient Background Information and Baseline Simulation State”. This should follow a traditional H and P format. The baseline state is the state the learner will find the simulation in at the beginning of the exercise. The baseline state for your simulation is developed by manipulating the simulator’s “perfect” 70kg, healthy physiology to resemble the patient you envision. You will need to also write down the “trigger” to move to the next state.

 

The next component is “Scenario Development States 2-?”. For each state you should write down what you would like the learner to do, what happens to the patient (including vital sign changes, lab values, etc) and what the trigger would be to move to the next state.  The table on the “Clinical Course for Scenario” page may be used in lieu of these pages if you prefer.

 

The final component of the template is the “Parameter Adjustment Form”. This should not be filled in unless you have scripted many cases. These tables will be used in the simulator programming process to keep track of the adjustments made to the simulator to achieve the “look” of the desired patient.
