| Abstract | Introduction: Prehospital teamwork occurs in dynamic environments where paramedics work together using technologies to care for patients. Despite increasing interest in using head-worn displays (HWDs) to support prehospital workers, little is known about how HWDs affect teamwork. Methods: We tested the effect of HWDs on the team processes and patient care of paramedic trainee teams in a laboratory study using an online prehospital simulation environment, SPECTRa. In a randomized crossover design, 20 two-person teams worked in the SPECTRa laptop environment from separate physical rooms to assess and treat 2 simulated patients in 3 prehospital patient care scenarios. In each scenario, each trainee used either an HWD, a tablet computer (TAB), or no mobile device (CON) to help them monitor the vital signs of both patients. We measured team processes based around 3 themes of mutual understanding, team performance, and administered an 18-item questionnaire about teamwork and use of the devices. Results: The mean number (HWD = 11; TAB = 7; P = 0.061) and duration (HWD = 1746 milliseconds; TAB = 1563 milliseconds; P = 0.504) of attention switches that teams made toward the mobile device did not differ with HWDs or TABs. However, teams switched attention between patients less with HWDs than with TABs (P = 0.026) or CON (P = 0.007) (medians: HWD = 5; TAB = 8; CON = 8). Teams communicated less when using HWDs than TABs (P = 0.017) (medians: HWD = 76; TAB = 96; CON = 83), but there were other mixed effects on communication. Team performance did not differ across device conditions on the timeliness to notice critical patient changes (P = 0.387) (medians: HWD = 244 seconds; TAB = 246 seconds; CON = 168 seconds) or to complete the scenarios (P = 0.212) (medians: HWD = 800 seconds; TAB = 913 seconds; CON = 835 seconds). Questionnaire results revealed some perceived benefits of the HWD. Conclusions: Head-worn displays may let prehospital teams monitor each other's performance more efficiently than TABs or CON, requiring less communication to maintain patient care performance with lower workload than with TABs. However, improvements in mutual understanding with HWDs compared with CON were more evident in teams' preferences than in actual behavior. Further research is needed to confirm and extend these results. |
