The purpose of this study was to investigate the acute effects of the electromagnetic waves (EMW) emitted by mobile phones on attention in emergency physicians.
This single-center, prospective, randomized, double-blinded clinical study was performed among emergency physicians in a tertiary hospital. Thirty emergency physicians were enrolled in the study. Initial d2 test was applied in the evaluation of attention and concentration of all the physicians, who were randomly assigned into one of two groups. The control group members hold mobile phones in 'off' mode to their left ears for 15min. The members of the intervention group hold mobile phones in 'on' mode to their left ears for 15min, thus exposing them to 900-1800MHz EMW. The d2 test was re-applied to both groups after this procedure. Differences in attention and concentration levels between the groups were compared.
Difference between initial and final d2 test in total performance (TN-E, p=0.319), in total number of figures marked (TN, p=0.177), in test performance percentile (PR, p=0.619) and in attention fluctuation (FR, p=0.083) were similar between the groups. However, difference in the number of figures missed (E1 selective attention, p=0.025), difference between numbers of incorrectly marked figures (E2, p=0,018) and difference in focus levels (E, p=0.016) were significantly in favor of the intervention group.
According to our study findings, the EMW emitted by mobile phones has no deleterious effect on the attention and concentration levels of emergency physicians, and even has a positive impact on selective attention levels.
本研究旨在探讨手机发出的电磁波(EMW)对急诊医师注意力的急性影响。
这是一项在一家三级医院进行的单中心、前瞻性、随机、双盲临床研究。纳入了 30 名急诊医师。所有医师均接受初始 d2 测试,评估其注意力和集中力,然后随机分为两组。对照组医师将手机调至“关闭”模式置于左侧耳边 15 分钟。干预组医师将手机调至“开启”模式置于左侧耳边 15 分钟,从而使他们暴露于 900-1800MHz EMW 中。该程序完成后,再次对两组进行 d2 测试。比较两组之间注意力和集中力水平的差异。
两组之间在总表现(TN-E,p=0.319)、标记的总数字(TN,p=0.177)、测试表现百分位数(PR,p=0.619)和注意力波动(FR,p=0.083)方面的初始和最终 d2 测试差异无统计学意义。然而,在漏标数字(E1 选择性注意力,p=0.025)、错误标记数字之间的差异(E2,p=0.018)和焦点水平之间的差异(E,p=0.016)方面,干预组具有显著优势。
根据我们的研究结果,手机发出的 EMW 对急诊医师的注意力和集中力水平没有不良影响,甚至对选择性注意力水平有积极影响。
