What is a virtual patient? - entry level

  • Elements

    • Scenario

    • Choices and consequences

    • First person participant

  • User interface

Models for Virtual Patients


Example

Example

  • Robert is a 6 week old boy who presents to A+E with poor feeding and no other symptoms.

  • Examination is entirely normal apart from a temperature of 38.1° C

  • What should you do?

Reassure and send

home with paracetamol

Take blood cultures

and start on antibiotics

Models for Virtual Patients


Models for virtual patients

  • You chose to reassure and send home with paracetamol.

  • Robert represents 6 hours later unresponsive with intractable convulsions.

  • A post mortem demonstrates bacterial meningitis.

  • Fevers in the very young should always be taken seriously as there are rarely any localising signs

Example1

Example

  • Robert is a 6 week old boy who presents to A+E with poor feeding and no other symptoms.

  • Examination is entirely normal apart from a temperature of 38.1° C

  • What should you do?

Reassure and send

home with paracetamol

Take blood cultures

and start on antibiotics

Models for Virtual Patients


Models for virtual patients

  • You chose to take blood cultures, clean catch urine, lumbar puncture and start on antibiotics

  • This is good, because the child had bacterial meningitis. Your interventions saved Robert’s life.

  • Clinical signs are often absent or subtle in the young.

  • Elements

    • Scenario

    • Choices and consequences

    • First person participant

  • User interface

  • Allows realistic choices

  • Has realistic consequences

  • Appropriate for level of user

  • Links to/contains education

Models for Virtual Patients


Generic problems

Generic problems

  • Inflexible

  • Expensive to set up

  • Realistic choice models require clinician time

  • Visually appealing models require programmer time

Different models to cope with choice1

Hi-Fi

Different models to cope with choice

Algorithm based

Linear

Lo-Fi

High degree of visual/aural realism

Complex programming

Expensive ++

$100,000

Solve problem with cash

Different models to cope with choice2

Hi-Fi

Different models to cope with choice

Algorithm based

Linear

Lo-Fi

Participant choices input information into a calculator that outputs clinical change

Complex formulae at the heart

No narrative

Good for physiology or biochemical scenarios

Solve problem with ‘infinite’ choice

Models for Virtual Patients


Different models to cope with choice3

Hi-Fi

Different models to cope with choice

Algorithm based

Linear

Lo-Fi

Allows only one route through the scenario

Incorrect responses lead to immediate correction

Minimal real choice

Good to test knowledge of protocols

Poor for realism - problem not solved

Easy to create

Different models to cope with choice4

Hi-Fi

Different models to cope with choice

Algorithm based

Linear

Lo-Fi

Multiple choices at each step

Emphasises decisions

Minimal attention to appearance

Cheap

Problem solved!

Welcome. You have now been a paeditrician since 4 pm, when your shift started.

Its day 1 of the job, and you are trying to remember all that stuff from the paed course. Anyway, it wasn't too busy and now you have discovered the mess and the takeaway menus. A Lamb Rogon Josh has arrived and you are half way through, when the crash bleep goes off

"Paediatric arrest in A+E".

What would you like to do?

Finish curryRun to A+E

Advantages of lo fi nodal approach

Advantages of Lo-Fi nodal approach

  • Quick

  • Adaptable

  • Linkable

  • Uses clinicians and programmers effectively

  • Anyone can do it!
