2. Learning objectives • Why simulation? • Features of a simulator • Apply simulation technology • Limitations and resource requirements

3. A traditional approach to learning

4. Problem #1 • Just because students learn a task in the classroom doesn’t mean they can demonstrate successful performance during a crisis.

5. Problem #2 • Some clinical experiences are so life threatening that students are not going to be involved in the management.

6. Problem #3 • Some are so rare that the student may not ever experience the situation until they are in the midst of caring for the patient.

7. Different simulation formats • Patient management problems (paper/pen) • Computerized simulation • Internet-based • Role playing/standardized patients • Mannequin-based (e.g., CPR BCLS trainer) • Virtual reality

9. Why simulation? • Used in many “high reliability” fields • Aviation • Nuclear power • Military flight operations

10. Why simulation? • No risk to patients • Many scenarios can be presented, including uncommon but critical situations in which a rapid response is needed • E.g. malignant hyperthermia 1:40,000 cases • Participants can see the results of their decisions and actions; errors can be allowed to occur and reach their conclusions

11. Why simulation? • Identical scenarios can be presented to different clinicians or teams • The underlying causes of the situation are known • With mannequin based simulators clinicians can use actual medical equipment • examine limitations in the human-machine interface

12. Why simulation? • Re-create clinical environments • Assess interpersonal interactions with other clinical staff • Evaluate and improve teamwork, leadership, and communication skills

13. Why simulation? • Intensive and intrusive recording of the simulation session is feasible • Audiotape • Videotape • Physiological monitoring of participants (EEG, ECG, etc.)

14. Why simulation? • There are no issues of patient confidentiality • Recordings can be preserved for research, performance assessment, or accreditation

15. How can we use simulation? • Skills training • Evaluation • Epidemiology and modification of errors (and their consequences) • Crisis resource management

16. What can you teach/evaluate? • Specific skills • Intubation • Bronchoscopy • Defibrillation • Integration of knowledge, skills and decision making • Resuscitation • Refractory hypoxemia

19. Evaluation of the evaluation tool • Type of simulator • Low to high fidelity • Type of simulation • Full theatre environment or real location • Training device for specific tasks • Efficacy of assessment • Valid • Reliable

20. SIM MAN

21. Life-size mannequin

22. Computer Controlled

24. Teach airway management

25. Use airway devices

26. Fibreoptic intubation

27. Difficult airway • Decreased cervical range of motion • Tongue edema • Pharyngeal edema • Laryngospasm • Trismus • Fiberoptic intubation/bronchoscopy • Surgical airway • Detectable carbon dioxide

28. Breath sounds

29. Check pulse & blood pressure

30. Obtain peripheral IV access

31. Mask ventilation

32. Decompress tension pneumothorax

33. Monitor cardiac rhythm

34. Shock unstable rhythms

35. Additional features • Chest tube insertion • Invasive hemodynamics • Ventilator management (including HFOV)

36. Control crisis situations

37. Give feedback

38. Assessment instruments • Specific • Debriefing (oral or written…good for factual) • Observation and scoring system (checklist or score sheet or palm pilot) • Time to performance of specific task • Global • Simulated mortality as end-point • Time to solve problem

39. How can we use simulation? • Skills training • Evaluation • Epidemiology and modification of errors (and their consequences) • Crisis resource management

40. Epidemiology of Medical Error • Types of errors made during anaesthesia simulation Schwid and O’Donnell Anesthesiology 1992

41. Crisis Resource Management • Using all available resources during a crisis to achieve safety and efficiency • Information • Equipment • People

42. Crisis Resource Management • Error countermeasures • Reduce the frequency of errors • Correct errors • Limit the impact of errors

43. Resources • Simulator PLUS operational budget • Competency standards • Who/what are you testing? • Content experts • Set objectives and clinical setting • Simulation experts • Translate objectives and clinical setting into functional simulation scenarios • AV equipment (debriefing)

44. Limitations of simulation • Difficult to demonstrate improved outcome from use of simulation • Adverse events are unusual • Extreme number of potential confounders • Forced to use simulation performance as surrogate outcome

45. Initiatives at MSH

46. Initiatives at MSH • Mock cardiac arrests • ACLS protocols • Use of equipment • Systems issues (elevators, cancel arrest) • Crisis resource management • Feedback/debriefing

47. Initiatives at MSH • Life-saving delegated medical acts • ICU/CCU nurses • Use of epinephrine/atropine • Defibrillation • Pre-ACLS interventions • Bag-valve-mask ventilation • Understanding respiratory failure and shock

48. Initiatives at MSH • Medical and Critical Care Residents • Continuing education courses • Difficult airway management • Advanced ARDS strategies • Technology evaluation • OCCIN Project Multidisciplinary approach Portable

49. Parting comments • Simulation is fun for students and teachers • You can use simulation technology as an evaluation tool • Choose the most appropriate tool for achieving educational goals • Remember basics of education, otherwise simulator is an expensive toy
