Board 316 - Research Abstract Using Simulation to Evaluate Communication Headsets for Trauma Care (Submission #1158)

Introduction/Background As part of wider DoD funded research project looking at reducing communication and coordination problems in trauma care, we evaluated open-communication headsets that allowed information and decisions to be shared across the team. Due to the critical nature of traumas, the headsets were tested in simulation in order to avoid any potential negative impact on a real trauma patient. We hypothesized that the headsets would aid communication, reduce workload and reduce task completion time. Methods Two simulation sessions were conducted to test the use of headsets. During the simulations, the residents were asked to place a central line. The first simulations were conducted in quiet conditions, which we realized was not realistic as the trauma bay can be crowded and noisy with frequent distractions and interruptions. In the second simulation, to make the scenario more realistic, the residents were given a detailed patient scenario, distracting patient care noises were played during the procedure and multiple staged nursing interruptions were infused. We measured time to complete the task, subjective workload using the NASA Task Load Index (TLX) and garnered subjective impressions of their use. Results All considered the second simulation to be extremely effective and engaging. The surgeons liked that the headsets allowed for easier communication when people were not right next to each other. The headsets provided good clarity in a chaotic environment but the surgeons noted that it is difficult to focus on one person when so many voices are coming through the headset. They also felt like the headset could slip off at any time. The mean time to task completion was about 4% faster (6mins 28 seconds with vs 6 mins 44 seconds without), while the TLX was one point (<1%) higher. Conclusion Realistic environmental simulation allowed the evaluation of this technology. The headsets assisted clarity of communication and improved task completion time but at the expense of workload. Basic design issues also reduced efficacy and increased perceived risk. Overall, there was not enough benefit to warrant further investigation of this technology. Disclosures Department of Defense W81XWH-10-1-1039 W81XWH-10-1-1039.
