To assess whether the capacity to utilize cues amongst emergency physicians is associated with differences in the capacity to recover performance following an interruption.
Interruptions are implicated in errors in emergency medicine due to the cognitive load that they impose on working memory, resulting in a loss of performance on the primary task. The utilization of cues is associated with a reduction in cognitive load during the performance of a task, thereby enabling the allocation of residual resources that mitigates the loss of performance following interruptions.
Thirty-nine emergency physicians, recruited at a medical conference, completed an assessment of cue utilization (EXPERTise 2.0) and an online simulation (Septris) that involved the management of patients presenting with sepsis. During the simulation, physicians were interrupted and asked to check a medication order. Task performance was assessed using scores on Septris, with points awarded for the accurate management of patients.
Emergency physicians with higher cue utilization recorded significantly higher scores on the simulation task following the interruption, compared to physicians with lower cue utilization (p = .028).
The results confirm a relationship between cue utilization and the recovery of performance following an interruption. This is likely due to the advantages afforded by associated reductions in cognitive load.
Assessments of cue utilization may assist in the development of interventions to support clinicians in interruptive environments.
评估急诊医师利用线索的能力是否与中断后恢复表现的能力存在差异。
由于中断对工作记忆造成的认知负荷，它们会导致急诊医学中的错误，从而导致主要任务的表现下降。线索的利用与任务执行过程中的认知负荷降低有关，从而能够分配剩余资源，减轻中断后表现下降的影响。
在一次医学会议上招募了 39 名急诊医师，他们完成了线索利用评估（EXPERTise 2.0）和在线模拟（Septris），涉及处理患有败血症的患者。在模拟过程中，医师会被打断并要求检查药物医嘱。任务表现通过 Septris 的分数进行评估，为准确管理患者提供分数。
与线索利用率较低的医师相比，线索利用率较高的急诊医师在中断后模拟任务中的得分显著更高（p=0.028）。
结果证实了线索利用与中断后表现恢复之间的关系。这可能归因于认知负荷降低带来的优势。
线索利用评估可能有助于开发干预措施，以支持在中断环境下的临床医生。
