DFD level 1 description

Process 1.0: Virtual Triage and Registration

The patient sends symptoms and registration details for triage. The system responds with triage results, scheduling options, or ED visit instructions. Registration and triage data are stored in the database, and relevant information is sent to the ED Load Status process.

Process 2.0: ED Load Status

The ED updates its current load and capacity, which is stored in the database. This data is used by the Virtual Triage process to assign patients and notify them accordingly.

Process 3.0: Patient Notification

The system sends patients notifications regarding their ED visit time based on the ED’s load or provides alternative actions.

Process 4.0: Appointment Management

Patients send requests for appointments or changes. The system stores or updates this information in the database and confirms the appointment to the patient.

Data store 5.0: SQLite Database

The database stores and retrieves patient triage, ED load, and appointment data for various processes in the system.
