1. System Description

The Mister Ed system is a software solution designed to address the issues of overcrowding and overload in Emergency Departments (EDs). This system aims to provide a more efficient process for individuals who believe they require medical attention and are considering a visit to the ED. Below is a description of the system:

  1. User Registration: Individuals who feel the need to visit an ED can access the Mister Ed system through the web. They will be required to register virtually, providing their basic information and medical history.

  2. Virtual Triage: After registration, users undergo a "virtual triage" process. During this phase, a series of questions and assessments are conducted remotely to evaluate the severity of the user's condition.

  3. Triage Outcome: Based on the virtual triage results, users are given recommendations. These recommendations may include:

    • ED Visit: If the system determines that an ED visit is necessary due to the severity of the condition, users are instructed to visit the ED
    • Alternative Care: For less severe cases, users are given alternative healthcare options, such as visiting a primary care clinic (General Practitioner or GP), taking over-the-counter medication, or contacting a nurse or clinician hotline via phone or internet for further guidance.

  4. Remote Waiting: Patients who are advised to visit the ED are placed in a virtual queue and can safely wait are allowed at home until it is their turn to see a doctor.

  5. Notification and Updates: The Mister Ed system manages the virtual queue and notifies patients when it's their turn to be seen by medical staff at the ED.

Use Case 1. View Wait-time
Description People who feel that they need to visit an Emergency Department (ED) will be able to use Mister Ed to understand the current load of EDs in their area.
sources [Project Milestone 1 - Scenarios], [BrightSpace]
Assumption
  • Mister Ed is available
  • Mister Ed correctly displays the current load of EDs
Actors Patient
Steps
  1. Patient navigates to Mister Ed (website or app)
  2. Patient uses their current location
  3. Mister Ed displays the current load of nearby EDs
Issues Mister Ed might have unexpected downtimes/maintenance.
Use Case 2. Virtual Triage
Description Using Mister Ed, Patients will be able to register virtually and undergo a "virtual triage" to determine whether they really should visit the ER or potentially follow another course of action.
sources [Project Milestone 1 - Scenarios], [BrightSpace]
Assumption
  • There must exist EDs near their area.
  • Mister Ed must be updated correctly and consistently.
Actors Patient
Steps
  1. Patient completes the virtual triage.
  2. Mister Ed determines the next steps for the patient.
Issues Patient completes the virtual triage wrong and is misdiagnosed.
Use Case Extension 3. GP Visit EXTENDS 2.Virtual Triage
Change Triage determines that patient should visit their GP.
Actors
  • Patient
  • GP
Steps
  1. Mister Ed recommends that patient should visit their GP.
  2. Patient visits their GP and is treated by them.
  3. Nurse determines that Patient is eligible for ED. Patient is added to ED waitlist

Use Case Extension 5. Enter Waitlist and Wait from Home EXTENDS(2. Virtual Triage AND 3. In-person Triage AND 4. Hotline)
Change Patients who still need to visit the ED can wait from the comfort of their home and will be notified to come in when it is time to see them.
Actors
  • Patient
  • Patient Load Database (PLDB)
Assumption
  • Patient is in the ED waitlist
Steps
  1. Patient waits for their turn in the comfort of their own home
  2. PLDB notifies the patient of their turn at the ED
Issues How do we ensure that the patient was notified? What if the patient becomes unreachable (i.e. their condition becomes worse)?
