New trends / interest in Human Factor based Simulation
Team Training
• NATO SOF Medical
• AHA Sim/CRM Italy
To err is human … … the consequences are variable…
It is risky to be a patient and: The problem remains big…
„Disappointing, but no surprise� (Landrigan): • Patient harm is frequent and wide spread • The incidence did not decrease in the last years! • 18% of hospitalized patients are harmed by care • More than 60% of the cases are preventable • 1,5 to 2,4% of incidents resulted in death (1:50 bis 1:100)
(medical error was causal or contributing)
Causes of accidents in medicine
70 % due to „Human Factors� (preventable?)
• Not a lack of medical knowledge
• But problems with transfering theoretical knowledge into meaningful actions in the real world
• Problems with Complexity
• Team, Communication (Not yet appropriately reflected in medical education !)

Resuscitation & Reality
• Chest compressions in only 48-76% of available time
• Correct depth of compression 28-63%

Crisis Resource Management (CRM is derived from Aviation)
Definition „The ability to translate the knowledge
of what needs to be done into effective team activity in the complex
and ill-structured real world of medical treatment�
David Gaba, Stanford
CRM and
Non-technical Skills (NTS) • Know the environment
• Anticipate and plan
• Call for help early
• Exercise leadership and followership
• Distribute the workload
• Mobilize all available resources
• Communicate effectively
• Use all available information
CRM Key Points
Nach Rall, Gaba
in: Miller, Anesthesia
6th Edition (2005)
• Prevent and manage
fixation errors
• Cross (double) check
• Use cognitive aids
• Re-evaluate repeatedly
• Use good teamwork
• Allocate attention wisely
• Set priorities dynamically
Communication + CRM
� Meant

� Said
is not heard

Components of CRM
Individual, cognitive Elements
• Limitations of Human Factors (“Allocation of Attention”, cognitive aids, checklists)
• Dynamic Decision Making • Planing & Antizipation • Use all available Information • Fixation error
Team Management and Communication
• Leadership & followership • “Assertiveness” • Effective Communication (!) • Distribution of workload • Call for help early • Use all available resources

Adult Learning
Principles
“Why should I change anything?”
The adult learner has to feel
a need to change !
(from self-reflection)
“Love your participants!”
General Assumption: All participants are highly motivated,
trained and skilled adult professionals

Instructors: “You are not a god”
" You have no power over your participants!
" You can´t impose on them what to do!
" They have cared for patients yesterday and
will do so tomorrow!
Do we critique colleagues and tell them what was wrong ?
Yes ! But:
- with exact observable behaviours - in a respectful manner - without any assumptions
- focused on finding out „Why�

Advantages of “in-situ” simulation team training
• Training of actual team – interdisciplinary
• Training in the real environment
• Optimizing of Equipment/Layout and Processes !
• Working area = Learning area
• Safety culture boost
• Positive Team Intervention
• Long lasting effects (self-sustaining from inside the team)

Humans do err
„Zero-Error-Strategy� is the wrong goal! (Kpt. M. Müller, 2007, Director Flight Safety German Lufthansa)
Mean Time Between Failure (Human Performance Messungen)
• Routine, used task 30 min • Complex Tasks, no Stress 5 min • Complex Tasks, + Stress 30 sec
Example: Emergency team, 4 people, working for 20 min:
a) Common team + Stress:
4 x 20 x 2 = 160 ERRORS ! b) CRM/Sim-Trained Team (no stress):
4 x 20 x 0,2 = 16 Errors ! (10-fold decrease!)
CRM Simulation Team Training
• Know the environment
• Anticipate and plan
• Call for help early
• Exercise leadership and followership
• Distribute the workload
• Mobilize all available resources
• Communicate effectively
• Use all available information

guideline: examples emergency room
organization Trauma teams in the ER must follow a standardized and systematic work up. They must be trained.
chest trauma: diagnostics what is the role of clinical evaluation of the chest ?
Recommendation ! a clinical examination of the chest must be performed GoR A
! auscultation should be performed as part of the clinical examination GoR B
Comment: Even if there are only scarce scientific evaluations on the role of the clinical examination of the chest in trauma patients the experts agree that clinical examination is a prerequisite for rapid detection of relevant injuries that could be life threatening and necessitate rapid intervention. This is also true for reevaluation when arriving in teh emergency room, even if a thoracic drain had already been placed in the prehospital setting because of possible changes of the patients status.
chest trauma: radiological work up
If a chest trauma cannot be excluded a radiologic evaluation must be performed in the ER .
A CT of the chest with contrast medium should be performed in any patient with signs of a severe chest trauma.

indication for thoracotomy
Thoracotomy can be performed in case of initial blood loss of >1.500 ml or in case of blood loss of >250ml/h for more than 4 hours.
emergency room thoracotomy In patients with blunt trauma and without vital signs at the site of the accident ER thoracotomy should not be performed
posttraumatic coagulopathy Posttraumatic coagulopathy has negative influence on outcome. It must be detected and treated immediately in the ER .
Thrombelastography/-metry (ROTEM/ ROTEG) can help to monitor and monitor treatment of posttraumatic coagulopthy
treatment of coagulopathy A massive transfusion protocol should be implemented and used.
In case of coagulopathy the RBC/ FFP ratio should be 2:1 to 1:1 if FFP is used.

• A huge step forward
• Established the structured system and common language for trauma care
• New educational approach to teaching/learning
In the beginning…
Bologna, Italy in 2002
Letter to the Editor in Resuscitation
Do we need a European approach to trauma care? by Karl-Christian Thies.
Resuscitation 2004:60:113-114
Letter to the Editor • “…There is obviously a demand for a reasonable,
commonly accepted approach and an enhanced programme of training in trauma care in Europe.”
• “… it seems sensible to develop a European approach to trauma resuscitation that is more flexible, based on the best evidence available, and which is adjustable to local conditions. We suggest that an ERC Task Force be established in order to create European guidelines on trauma resuscitation.”
3
ATLS%Europe,Mee.ng,Berlin,,April,2012,—,The,European,Trauma,Course,—,Freddy,Lippert,
The vision of the ETG • To use state-of-the-art evidence based knowledge
• To be interdisciplinary and multi-specialty
• To teach a team approach reflecting European practice
• To address the pre-hospital and the early hospital period to enhance continuity of care
• To meet the requirements of contemporary adult learning
• To be mainly practical
• To be flexible and adaptable enough to meet the different regional needs within Europe
• To be affordable throughout Europe

ETC comments from experts
• “ATLS and the ETC should walk arm in arm around Europe”
• “ATLS for basic vertical management and ETC for advanced horizontal management team training”

ATLS%Europe,Mee.ng,Berlin,,April,2012,—,The,European,Trauma,Course,—,Freddy,Lippert,
ETC comments from experts “The ETC builds on the principles of ATLS and allows
doctors to take knowledge and skills and use them as part of a team. It particularly struck me watching the team scenarios how individual components of ATLS were all running simultaneously.”
“ATLS provided a valuable springboard from which the ETC could then go on and explore more complex issues relating to trauma care in particular training in team management.”
“My hope is that the two courses will flourish along side each other in Europe and particularly in the United Kingdom.”
ETC comments from experts “Validity – pressure increases as does complexity over the
two days. Appropriate content – real cases without ridiculous injuries or unreal circumstances. Team allowed to play their own role at work rather than being forced to play the role of someone you are not – so the validity of the team trying to work out what they are capable of as a whole and who they need to supplement was very real.”
“Overall impression – I thoroughly recommend this course, it is the natural and logical progression for all StRs and consultants – and should be a mandatory course once there are enough faculty in the UK.
“Support – Yes – with no reservations.”
Thoughts for the future Trauma care with ETC and ATLS courses • A common goal • International guidelines on trauma care
like the ILCOR (ilcor.org) • International consensus on science • International treatment recommendations • Courses with different approaches (basic,
individual, skill training, team training, team leader training)
•
SUMMARY The European Trauma Course: • Is interdisciplinary • is team approach • is practical • is affordable • is flexible and adaptable • Uses modern adult learning methods

• Heart Rate: • Association between reduced SBP and tachycardia: 128mmHg (HR<100) vs.114 mmHg (HR>140)
• No relevant changes in RR and GCS (15 vs. 14)
• Systolic Blood Pressure: • No relevant tachycardia observed (83 vs. 88 beats/min)
• RR unaltered
• Respiratory rate: • No hypotension in any group
• Moderate tachycardia (HR >100 bpm/min) in patients with a RR > 30
Limitations of the studies
• Retrospective analysis
• Pulse pressure, urinary output were left out
• Need for �translation�
What do vital signs tell us?
• Heart Rate • Poor correlation between hypotension and tachycardia: Victorino 2003, J Am Coll Surg
• neither specific nor sensitive in determing the need for emergent intervention, severe injury or transfusion
of pRBC: Brasel 2007, J of Trauma
• Relative bradycardia (SBP ≤90 mmHg; HR ≤ 90 bpm) in 44% of all patients: increased mortality, occurs
in older patients: Ley 2009, J of Trauma
What do vital signs tell us?
• Systolic Blood Pressure • Late marker of shock, „compensated phase of shock��
• ≤ 110 mmHg as a cut-off point for increased mortality: Husler 2012, Resuscitation
• Dependent on initial treatment (fluids, vasopressors)
• Glasgow Coma Scale
• Predictor for mortality, outcome
• Prehospital intubation, isolated head injuries
…do we need a modified classification?
„Yes�
Based on a parameter which fulfills:
- Fast assessment
- Identifying patients „at risk� (transfusion, injury severity)

Summary
• The ATLS classification - a good �teaching tool�,
but it seems not to reflect clinical reality appropriately
• �Modified classification of shock� • �teaching tool�
• Evidence based
• BD as a physiological marker of shock • Dilemma: POCT in every ED or can we redefine a �new combination of vitals�?
