Intraoperative surgical crisis management is learned in an unstructured manner. In aviation, simulation training allows aircrews to coordinate and standardize recovery strategies. Our aim was to develop a surgical crisis simulation and evaluate its feasibility, realism, and validity of the measures used to assess performance.
Surgical trainees were exposed to a bleeding crisis in a simulated operating theater. Assessment of performance consisted of a trainee's technical ability to control the bleeding and of their team/human factors skills. This assessment was performed in a blinded manner by 2 surgeons and one human factors expert. Other measures consisted of time measures such as time to diagnose the bleeding (TD), inform team members (TT), achieve control (TC), and close the laceration (TL). Blood loss was used as a surrogate outcome measures.
There were considerable variations within both senior (n = 10) and junior (n = 10) trainees for technical and team skills. However, while the senior trainees scored higher than the juniors for technical skills (P = 0.001), there were no differences in human factors skills. There were also significant differences between the 2 groups for TD (P = 0.01), TC (P = 0.001), and TL (0.001). The blood loss was higher in the junior group.
We have described the development of a novel simulated setting for the training of crisis management skills and the variability in performance both in between and within the 2 groups.
术中手术危机管理是以一种非结构化的方式习得的。在航空领域,模拟训练能让机组人员协调并规范恢复策略。我们的目的是开发一种手术危机模拟,并评估其可行性、逼真度以及用于评估表现的措施的有效性。
外科实习医生在模拟手术室中面临出血危机。表现评估包括实习医生控制出血的技术能力以及他们的团队/人为因素技能。该评估由两名外科医生和一名人为因素专家以盲法进行。其他测量包括时间测量,如诊断出血时间(TD)、通知团队成员时间(TT)、实现控制时间(TC)和缝合伤口时间(TL)。失血量用作替代结局指标。
高级(n = 10)和初级(n = 10)实习医生在技术和团队技能方面均存在相当大的差异。然而,虽然高级实习医生在技术技能方面得分高于初级实习医生(P = 0.001),但在人为因素技能方面没有差异。两组在TD(P = 0.01)、TC(P = 0.001)和TL(0.001)方面也存在显著差异。初级组的失血量更高。
我们描述了一种用于危机管理技能培训的新型模拟场景的开发,以及两组之间和组内表现的变异性。
