A100Simulating to manage post thyroidectomy haematoma safely: Improving fidelity whilst reducing cost

Abstract

Simulation training sessions were designed at the University Hospital of Wales in order to implement the new national guidelines for the management of suspected haematoma following thyroid surgery [1]. Opportunities included on site portable training with a part task trainer and high-fidelity scenarios simulating patient deterioration following thyroid surgery in an immersive environment. Our initial design for the high-fidelity set-up included a simulated neck haematoma achieved by using a second generation supraglottic airway device (SAD) with an inflatable cuff placed in the manikin’s neck with the laryngeal opening outwards and tubing inside the chest. The opening was filled with red jelly, covered by simulated strap muscles (made from simulated small bowel with interrupted sutures) and simulated neck skin (which presented a sutured incision complete with steri-strips). Ongoing bleeding was simulated by injecting liquid jelly through the SAD’s gastric port via a long connecting tube in the manikin’s thorax. This simulation training increased confidence and familiarity with the steps required to manage post thyroid surgery haematomas in 100% (15/15) of candidates, with 73% grading the mannikin ≥4/5 for realism. However, it was costly to provide and time-consuming to set up. It was decided to try to make the set-up cheaper and easier to reproduce without impairing quality. Equipment costs were reviewed and alternative options identified. Expensive components included the SAD and bowel material, which were replaced with a cheaper SAD and a disposable tourniquet fashioned as shown in Making the simulation larynx and strap muscles. A step by step guide The cost of disposable props used in each session was reduced from £133.04 to £8.52 with the new equipment. The designers also felt it was significantly more robust and easier to reproduce. This approach could also be easily adapted for mobile part-task training, improving multi-disciplinary access to training. Feedback showed 47% of candidates felt the new set-up to be better, and 47% reported non-inferiority. Changing to new equipment resulted in a design that was significantly cheaper, easier to source and set-up, while being at least as realistic and offering training opportunities outside the high-fidelity environment.
