Contents:
• Multitrauma accidents• Emergency care in
Nordic countries - the BEST project
• Why use simulators?• Existing simulators• The DOVRE platform
• MATADOR • Goal/outline/time plan• Medical content• Current status• Comparison• MATADOR partners• Conclusion
Multitrauma accidents• strikes many young,
healthy, and ablebodied persons
• take many lifes
• Age < 35 years: the most frequent cause of death
• can often be effectively treated
• Most errors occur in the initial assessment phase.
http://www.trauma.org
In the emergency room• many groups of medical personnel
• time pressure
• rapid technological changes
• high staff turnover
• chaotic learning situation
No room for learning by doing !!
Hospitals in Nordic countries
• countries with long distances
• harsh weather conditions
• sparse population• many small hospitals• no national standard
for trauma care
The BEST projectThe BEST team visits rural hospitals.
1. Theory based on actual cases. 2. Training session are videorecorded. 3. Observation, review and feedback.
Success factors:
• Courses at each hospital
• Immediate feedback, focus on team performance
Why use simulators in medicine?
• Limited access to real training situations.• Simulation provides a way to gain
competence in emergency situations that seldom occur.
• Reduce the cost of training surgeons.• Reducing the risk to patients.
Existing simulators

DOVRE
• A tool for distributing 3D-graphics, sound and video
• Developed from scratch using C++• Multi-platform: win32 & Unix
(Linux/IRIX)• API for creating distributed virtual
worlds
(Distributed Object-oriented Virtual Reality Environment)
The EduAction project• using VR to enhance collaborative learning
• developed for pupils in the secondary school
• pupils take the role of interplanetary explorers, looking for planets suitable for new colonies
”Corpus Callosum”, the disaster-ridden planet

The DISCOVER projectDistributed training environment for the
offshore and maritime sectors
Haptic devices
• Haptic – related to the sense of touch
• Haptic displays - electromechanical device that deliver force sensation
• PHANToM premium 1.5 - to be integrated in the MATADOR prototype
MATADOR
• The goal is to develop and evaluate a simulation environment for managing acutely traumatized patients.
• Target group: both students and physicians.
• Proposal was presented to Nordunet2.
• 2.6 mill. NOK from Nordunet2.

Pilot scenario
7 year old girl on bicycle, hit by car
Unconcious when primary physician arrives, no immediate signs of external injuries
10 min: patient becomes concious, but weak
40 min: unstable vital signs, helicopter arrives
60 min: during transportation, patient develop spasms
65 min: respiration and circulation stop as helicopter arrives at hospital. Attempting heart/lung rescue. Conditions interpreted as head injury. Further treatment stopped.

MATADOR versus other simulators
• A multiuser system – training as a team• Advanced 3D-technology
MATADOR session manager
MATADOR partners:• Faculty of Medicine, University of Umeå• Multimedic AS• The Norwegian Medical Association• InterMedia, University of Oslo• Medical Faculty, University of Oslo• Boxer Technologies AS• Telenor R&D
Concluding remarks
• Nordic countries: similarities in culture, language, and health care systems
• A joint Nordic effort would be of substantial benefit
• Towards a Nordic standard?• URL http://amt.fou.telenor.no/MATADOR/
