Background:

• Internet of Things (IoT) applications offer potential benefits for healthcare settings.
• Effective requirement elicitation is crucial for successful IoT system implementation in hospitals.
• Emergency rooms present complex environments requiring robust system design.

Purpose of the Study:

• To describe the initial requirement elicitation process for an IoT application in a hospital emergency room.
• To demonstrate the utility of Rich Pictures and Use Cases for modeling healthcare IoT systems.
• To explore the generalization of specific emergency room scenarios to hospital-wide systems.

Main Methods:

• Utilized Rich Pictures for high-level system modeling.
• Employed Use Case modeling to define system interactions.
• Developed specific Use Case models for a myocardial infarction patient scenario.
• Discussed the generalization of models to a broader hospital context.

Main Results:

• Successfully modeled emergency room systems using Rich Pictures and Use Cases.
• Illustrated the application of these models to a critical patient scenario.
• Provided a framework for extending emergency room models to hospital-wide IoT systems.

Conclusions:

• The proposed modeling approach can enhance efficiency and safety in emergency rooms.
• Improved tracking of people, equipment, and supplies is achievable with IoT systems.
• Structured requirement elicitation is key for effective healthcare IoT deployments.
