Lab Activity: Block Diagram
When a patient arrives at the ED of the Medical Center of DeVry, demographic and insurance information is obtained. The ED registration clerk checks the facility master patient index and either updates information if the patient has previously been treated at the facility or enters the information if this is the patient’s first visit.
The triage nurse takes a medical history and performs an initial clinical evaluation. This information is entered into a computerized ED encounter form and an automated triage system categories the patient. The triage systems assign an available ED bed in the bed assignment system. The patient is put on the schedule to be seen by an ED physician. The ED scheduling system tracks a patient in the ED and captures information on diagnosis, treatments, provider interaction, and amount of time a patient spends in the ED. An ED physician sees the patient by schedule order. The physician performs an examination, orders tests, writes prescriptions, makes a diagnosis and makes a decision about patient disposition. The ED physician enters medical history, examination information, diagnosis, and patient disposition into the computerized patient EHR system. The ED physician enters medication and test orders in the order-entry system and orders are automatically routed to the clinical laboratory, radiology and pharmacy information systems.
Based on the scenario above, create a block diagram that will represent the system input, outputs, components and other applicable relationships.
STEP 1: Create a Block Diagram
- On the File menu, point to New, point to Block Diagram, and then click Basic Diagram.
- From Basic Shapes, drag shapes onto the drawing page.
- Resize and rotate shapes as necessary.
- If the shape has selection handles, drag one until the shape is the size you want. To resize the shape proportionally, drag a corner handle.
- If the shape has endpoints, drag an endpoint to the length you want.
- Select the shape, and then drag the rotation handle.
- You will use these shapes to create a diagram for the ED system components.
Click a shape to select it and do one of the following:
STEP 2: Create Components and Relationships
- To create components and relationships, drag appropriate shapes to your diagram to represent components and relationships. You can associate multiple shapes with the same component.
- To add text to a shape, select the shape and then type.
- To create inputs, outputs and interfaces, drag appropriate shapes to your components and relationships.
STEP 3: Create system inputs, outputs and interfaces
