Objective:
The study aimed to assess targeted simulation courses, including live animal operating, as complementary training tools with regard to 2 key surgical skills in early cardiothoracic surgeon training.
Methods:
Twenty UK surgical trainees (equivalent to cardiothoracic surgery resident physicians in the United States) in their first year of residency training were evaluated. Assessment of skills in pulmonary wedge resection and cardiopulmonary bypass were undertaken before and after 2 boot camp-style courses, including live animal operating (boot camp 1 and boot camp 2). Resident performance was evaluated by surgical trainers using objective structured assessment of technical skills matrices. Trainers completed a survey on skill development and trainer confidence in the trainee precourse and postcourse.
Results:
Trainee assessment scores pre- and postcourses were analyzed using a 2-tailed Wilcoxon signed-rank test demonstrating a significant improvement in trainee performance in boot camp 1 in performing cardiopulmonary bypass (median score, 21 precourse and 28 postcourse; P = .001) and pulmonary wedge resection (median score, 25 precourse and 32 postcourse; P = .012), and in boot camp 2, in performing cardiopulmonary bypass (median score, 28 precourse and 30.5 postcourse; P = .018) and pulmonary wedge resection (median score, 31.5 precourse and 37 postcourse; P = .018). Trainers reported increased confidence and decision-making competency of residents and increased confidence of trainers to allow more participation in management. It was found that 83.3% of trainers would support trainee attendance in subsequent years.
Conclusions:
Live animal operating as a component of targeted cardiothoracic surgery skill training courses significantly improves technical skills, builds confidence of surgical trainers in resident physicians' practice, and should be supported by the surgery community.

Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
