When Will You Need This?

To quickly implement the treatment section of an Emergency Department Model and when Fast Track treatment needs to be represented in a ED model.

Model Object

The following model object can be found in the model objects directory: ED \ ED3_a Treatment with Fast Track.

Ease of Use: Easy

Ease of Modification: Moderate

This model object is a part of a 8 model object Emergency Department series that can be accessed under the category ED.

1. ED1 Arrivals with Acuity

2. ED2 Triage

3. ED3_a Treatment with Fast Track

4. ED3_b Treatment with Fast Track Using Common Lab

5. ED4_a Patient Discharge

6. ED5_a Room Cleaning

7. ED6_a Patient Admit

8. ED7_a Resource Optimizer

This model object should be used in conjunction with other ED model object (ED Arrivals with Acuity, ED Triage, ED Discharge, ED Room Cleaning, ED Staffing Calculator, etc. to take advantage of predefined stats collection, routing attributes and built-in resources.)

How to Use the Model Object

1. Open Your Model

Open your model or create a new blank model.

2. Insert the Model Object into Your Model

1. Locate the model object ED3_a Treatment with Fast Track and select the insert button.

2. 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.

3. Connect to Your Model

1. Create a percentage route between the start of your model and the black box arriving to this model object. In case you are combining ED models, use a percentage route to connect the black box from ED2 Triage to the black box arriving in this model object.

2. In case you are combining ED models, create a Get and Free route from Triage Patient activity to Nurse resource.

3. Using a percentage route, connect the black box (connected from the Yes route) to the rest of your model. In case you are combining ED models, use a percentage route to connect to the black box in the ED4_a Patient Discharge model object.

4. Using a percentage route, connect the black box (connected from the No route) to the rest of your model. In case you are combining ED models, use a percentage route to connect to the black box in the ED6_a Patient Admit model object.

This Model Object is best when used with other ED model objects Scenario Parameters

4. Define Values

Change the scenario parameter values based on the Scenario Parameters information provided at the end.

5. 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 ED4_a Patient Discharge model object.
