AnTriEx and ViTriEx

AnTriEx and ViTriex are tools for simulation exercises in mass casualty scenarios. They are based on real situations and allows for participants to immerse themselves in realistic exercises that practice decision-making, prioritisation, organisation and much more. AnTriEx is an analogue tool where exercises are carried out in person and ViTriEx is a virtual tool that allows participants to conduct exercises digitally

What is AnTriEx?

AnTriEx stands for Analog Triage Exercise. It is a simulation tool that allows participants to practise how to organise, communicate, lead, make decisions and prioritise in mass casualty situations. It is a highly flexible, portable, and easy-to-apply tool that focuses on the learning and interaction of the participants. The simulation is done in person and the scenario is a fictional mass casualty event, based on real situations. The participants are taken to a mass casualty scene where the casualties are simulated by frisbees with attached information about their vital status. The participants coordinate themselves as a team in order to prioritise among the injured, provide primary care, communicate and make decisions in a chaotic and stressful environment, where resources and information is scarce.

AnTriEx can easily be adapted to the needs and level of knowledge of the participants. 

Learning Objectives 

  • Triage - Apply basic principles of prioritisation of casualties in a mass casualty event, where there is an imbalance between needs and resources. 
  • Communication & Leadership - Recognise the importance of good communication and leadership in a disaster response and reflect on best application of such.
  • Decision Making - Demonstrate an ability to make decisions about prioritisation of resources and casualties, in a context of resources scarcity and based on limited information. 

What do you need to use AnTriEx?

AnTriEx is a resource efficient simulation, both with regards to preparation time as well as the required material to implement it. The only resource needed is approximately 60 frisbees with attached patient information, and a simulation facilitator or facilitors.

What is ViTriEx?

ViTriEx is a simulation tool that allows participants to practice how to organise, communicate, lead, make decisions and prioritise in mass casualty events.  The simulation is done online, and the scenario is a fictional mass casualty event, based on real situations.  During the simulation participants are taken to the scene of a casualty, as well as to the emergency room of a smaller hospital. The participants are given different roles and must then prioritise among the injured, communicate and make decisions in a chaotic and stressful environment, where resources and information is scarce.  The simulation allows for direct feedback on the decisions that the participants make.

The patients that are used in a ViTriEx simulation are based on a patient data base kept by CRIMEDIM - Center for Research in Disaster and Emergency Medicine, Università del Piemonte Orientale in Novara, Italy, whom we collaborate with.

Learning Objectives

  • Apply basic principles of prioritisation of injured in a mass casualty event, where there is an imbalance between needs and resources.
  • Assign roles and organise a mass casualty scene.
  • Be able to, in a structured manner, make initial evaluation, stabilisation and re-evaluation of emergency injuries and symptoms in a mass casualty event.
  • Assure good communication techniques are used in disaster responses, as well as, in a clear manner, reflect on how such techniques can be implemented.

What do you need to use ViTriEx?

ViTriEx uses freely accessible software, with no need for licences or to download specific software. The tool is freely available to use for anyone who is interested. The only resources needed to conduct a simulation with ViTriEx are ordinary computers, internet access, and teachers with disaster medicine skill set.
