Use Case Textual Descriptions:

Use Case 1: Conduct Initial Virtual Triage

Use case	Conduct Initial Virtual Triage
Description	The Nurse conducts a virtual triage by interviewing the Patient and documenting symptoms, observations, and other information in real-time into the system. The Nurse uses this information to decide the appropriate course of action.

The Nurse documents the symptoms and observations in real-time using the system. 4. The Nurse makes a decision for what the next step is (e.g. whether to refer to a doctor, advise self-care, or recommend further medical evaluation).
Variations	- The Nurse may ask follow-up questions based on incomplete information from the patient.
Non-Functional	- The system should allow quick data entry and saving of information with minimal delay.
Issues	- What should happen when the Patient cannot provide enough information for a complete triage?

Assumptions	- The Receptionist manages the queue logistics (e.g. adding/removing patients).
Steps	1. The Nurse accesses the ED waiting queue. 2. The Nurse reviews patient priority levels based on triage results. 3. The Nurse adjusts the queue if any patients need faster attention. 4. The Nurse provides feedback to the Receptionist to update the waiting list if needed. 5. The Nurse coordinates with the Receptionist to manage the queue based on triage priorities.
Variations	- The Receptionist may notify the Nurse of any administrative changes (e.g., patient check-ins). - Patients may need to be re-triaged based on new symptoms.

Variations	N/A
Non-Functional	- The bed availability dashboard must refresh every 30 seconds.
