1 Using Simulation as a Teaching Tool American Association of Thoracic Surgery Developing the Academic Surgeon April 28, 2012 Edward D. Verrier, MD MerendinoProfessor of Cardiovascular Surgery University of Washington Surgical Director Joint Council on Thoracic Surgery Education

2 Simulation in Cardiothoracic Surgery Acknowledgments Nahush A. Mokadam, MD University of Washington James Fann, MD Stanford University Richard Satava, MD University of Washington

3 Background and Rationale TEACHING AND RESIDENT TRAINING Environment: Patient safety / outcomes Operating room efficiency Teamwork emphasis Work hours limitations Service still required Changes in general surgery training: Less open, more endoscopic Little vascular Changes in CT surgery practice Caseload Patients older, more co-morbidities Procedures more complex

4 Background and Rationale TEACHING AND RESIDENT TRAINING New skills and techniques Catheter based skills: TAVI, TEVAR Learner: Google generation: facts available, cognitive skills lacking Educator: Mixed priorities ACGME Competency initiative 6 basic ACGME competencies Assessment Technical skills Accountability Airline standards

5 Background TEACHING AND RESIDENT TRAINING Simulation has not been traditionally part of cardiac surgical training Several centers have informal or semi-formal curricula Due to the short training period (2-3) years, focus has been on clinical experience rather than simulation

6 SIMULATION IN CARDIOTHORACIC SURGERY SPECIAL CONSIDERATIONS Multiple sub-procedures / tasks to cardiac surgery Tasks that are not easily correctable Tasks that have serious consequences Tasks that may be visualized by only one surgeon Tasks that require educated assistance Different / unique anatomy in some cases Tools / instruments that require practice

7 Simulation as a Teaching Tool Basic Surgical Skills (knot tying, bronchoscopy) Pre-operative Planning (advanced imaging) Preparation for the Operating Room (warm-up) Crisis Management for Rare Events (CPB) Virtual Patients Cognitive skills Introduction of New Skills (catheter based skills) Team Training (communication, professionalism) Deliberate Practice (with mentor) Formative feedback (BID process) Assessment (criterion based)

13 AHRQ Cardiac Surgery Training Grant 1R18HS Collaboration of 8 institutions 2 groups of 16 first year cardiothoracic residents - Total 32 residents

14 AHRQ - Cardiac Surgery Training Grant Overview Simulator Based training for first year cardiothoracic residents in 6 different cardiac surgery modules, each over 7 weeks, for 2 years Formal simulator based training is 1/2 day per week for each resident

15 Specific Aims Learn the component tasks of a given module using a rigorous simulatorbased curriculum. Evaluate component task-based training of complex surgical procedures. Evaluate the effectiveness of deliberate practice of technical skills as a means of reliably achieving expertise. Teach the process of briefing and debriefing for evaluating performance. Analyze the data. Produce a curriculum for simulator based training. Make readily available to the entire surgical community the results of this project.

43 SIMULATION IN CARDIAC SURGERY METRICS for Simulation 1. Time for task completion 2. Quality of task 3. Economy of motion-tracking 4. Situational assessment 5. Logical sequence 6. Knowledge of anatomy 7. Crisis management

44 SIMULATION IN CARDIAC SURGERY OPERATIVE TEACHING ASSESSMENT 1. Feasibility 2. Reliability 3. Validity a. Predictive: predict future performance b. Content: intent to measure vs. actual content c. Concurrent: correlate with gold standard d. Construct: measure what we purport to measure e. Face: task or examination resembles real life

45 Future Directions Prerequisite Curriculum Training and Advancement Board RRC requirement / Certification Maintenance of Certification

46 Traditional Paradigm Change Halstedian - See one, do one, teach one Determined by patient flow Conventional fixed didactic lectures Subjective personal evaluation Specific time and place Next Generation Simulation Do many, mentored always Each student every variation at own pace Interactive, updated (web based) lecture Standardized, objective, criterion based evaluation Continuous at point of clinical care
