Introduction/Background Background: Simulation within the healthcare industry has become increasingly popular and has proven to be an effective tool1; however, it usually is associated with a high price tag.1,2 Thoracotomies are one of the most difficult surgeries to perform but are rare in occurrence and thus not performed frequently; therefore, skill level and self-efficacy tends to be low. A thoracotomy is an incision into the chest wall (i.e. thorax) and is performed in various situations including treatment or diagnosis of diseases, resuscitative, or emergency trauma to the chest.3 Practicing a thoracotomy in simulation often requires the use of either a cadaver or a fresh thorax, which is expensive, time consuming, and requires multiple stipulations (i.e. a room with proper ventilation, privacy regulations, transport laws, etc.). The creation of a Thoracotomy task trainer would eliminate these issues, be cost effective, and offer frequent training of a skill rarely practiced. Methods Objectives: Increase skill level and self-efficacy with residents;
Decrease the cost of training for thoracotomies; Create a low cost, reusable, mobile task trainer to increase competency; Develop effective communication between hospital staff during the procedure.

Methods: After developing and coordinating a previous thoracotomy training with over 40 general surgery residents and measuring outcomes, it was determined that although more costly than using a cadaver (approx. $2000), a fresh human thorax (approx. $5000) would be more beneficial, secondary to it being more realistic. Both the cadaver and thorax offer excellent training; consequently, they can only be used once. Additionally, feedback from residents who participated in past training indicated there was an obvious need for a cost effective, mobile, and reusable Thoracotomy task trainer. The cost to develop and construct the thoracotomy task trainer is approximately $200, while the cost to run one resident through the Thoracotomy task trainer is $5.

To do this, staff purchased (or find someone willing to donate) a used ALS SimMan by Laerdal)5 and carefully removed the mechanical parts from within the chest, making an open space. The idea is to then recreate a functioning chest wall with skin and ribs, as well as, a realistic substitute for a human heart; consisting of proper anatomy, fluid, and vasculature. Parts list included: ALS SimMan, cow ribs, pig pluck, IV and suction tubing, screws, zip ties, super glue, medium sized Tupperware to house pig pluck, zip lock bag, simulated blood, simulated human skin, and moulaged epigastric puncture wound. For training to be complete; a Thoracotomy Tray, pertinent medical instruments, and a subject matter expert are necessary. Results: Conclusion The thoracotomy task trainer is a cost effective, mobile, and reusable training tool. This innovative approach will allow each training center, hospital, healthcare facility the opportunity to build their own trainer, as well as, offering every resident the opportunity to perform this high stakes, low frequency procedure. Using this task trainer will amplify participants confidence, frequency of training, and skill level, while also helping to create an effective interdepartmental communication process throughout this procedure.5 All in all, the Thoracotomy task trainer is a low cost, highly efficient tool that can help save lives.
