To prioritize according to acuity assigned in the arrival, to forward the most severe patients first, to allow for the separate queuing and prioritization of a “Fast Track” and to allow people that have waited to long to exit the system as LWBS.
Where to Find the Model Object
The following model object can be found in the model objects directory:
- ED \ ED2 Triage
This model object is a part of a 8 model object Emergency Department series that can be accessed under the category ED.

How to Use the Model Object
- Open Your Model: Open your model or create a new blank model.
- Insert the Model Object into Your Model
- Locate the model object ED2 Triage and select the insert button.
- Move the cursor to the point of insertion and left mouse-click. The upper left corner of the model object will be inserted at the location of the mouse-click.In case you are combining ED models, move the cursor to the left of the black dot inserted with the last model object, then click.
- Connect to Your Model: Create a percentage route between the start of your model and ED Critical?. In case you are combining ED models, , use a percentage route to connect the black box to ED Critical?.Connect the black box after Triage Patient to the rest of your model. Incase you are connecting ED models, connect the black box to the starting black box in ED3_a Treatment with Fast Track or ED3_b Treatment with Fast Track Using Common Lab. This Model Object is best when used with other ED model objects Scenario Parameters
- Move Objects: Move all blue objects to a notes layer on your model.
- Define Values: Change the scenario parameter values based on the Scenario Parameters information provided at the end.
- Objects: The Fast Track Trigger Activity controls hours of operation for the Fast Track. This is only operational if the fast track scenario is on. There are two arrival routes on this trigger on arrival routes turns the fast track on, while the other turns it off.
- Action Logic: The following objects contain action logic, review the action logic if needed.
- Triage Patient activity.
- Route between Triage Patient and Waiting Room.
- Waiting Room storage.
- Route from Waiting Room to the black box.
- Route from Waiting Room to Terminate 1 activity.
- Both arrival routes coming from Fast track Trigger entity to Fast Track Trigger Activity.
- Waiting Room Controller activity.
- Completion: The model object is now integrated into your model, you should now be able to save and then simulate the model. You should now be ready to add ED3_a Treatment with Fast Track or ED3_b Treatment with Fast Track Using Common Lab model object.
