Multitasking (MT) is a term often applied to emergency medicine (EM), but it is still poorly understood. In an effort to facilitate MT research in EM, the authors conducted this pilot study to describe EM residents' scores on a Multi-Tasking Assessment Tool (MTAT) and compare these scores with the residents' work efficiency in the emergency department.
The authors administered a previously developed test of MT ability to EM residents. They performed a multiple regression analysis to determine the effect of MT ability on resident work efficiency, defining efficiency as the number of relative value units billed per hour. They controlled the analysis for year of training and medical knowledge using as a standard the in-service exam administered by the American Board of Emergency Medicine.
Complete data for 35 residents were available for analysis. Work efficiency was multivariately correlated with MTAT scores and year of training (P < .05). Whereas year of training explained the majority of the variance, a resident's MT ability accounted for a smaller but still significant portion.
This pilot study further validates the MTAT and lays the groundwork for further research in MT in EM. Resident year of training and MTAT scores explain the variability in resident work efficiency significantly more than medical knowledge. Understanding MT ability may ultimately help in resident selection, education, and remediation as well as career counseling and improvement of practice systems in EM.
多任务处理(MT)这一术语常被应用于急诊医学(EM),但其仍未得到充分理解。为推动急诊医学领域的多任务处理研究,作者开展了这项初步研究,以描述急诊医学住院医师在多任务评估工具(MTAT)上的得分,并将这些得分与住院医师在急诊科的工作效率进行比较。
作者对急诊医学住院医师进行了一项先前开发的多任务能力测试。他们进行了多元回归分析,以确定多任务能力对住院医师工作效率的影响,将效率定义为每小时计费的相对价值单位数量。他们使用美国急诊医学委员会组织的在职考试作为标准,对培训年份和医学知识进行了分析控制。
有35名住院医师的完整数据可供分析。工作效率与MTAT得分和培训年份存在多变量相关性(P <.05)。虽然培训年份解释了大部分方差,但住院医师的多任务能力也占了较小但仍显著的部分。
这项初步研究进一步验证了MTAT,并为急诊医学中多任务处理的进一步研究奠定了基础。住院医师的培训年份和MTAT得分对住院医师工作效率变异性的解释,比医学知识显著得多。了解多任务能力最终可能有助于急诊医学住院医师的选拔、教育和补救,以及职业咨询和实践系统的改进。
