We intend to evaluate the change of different cognitive functions after a guard shift in physicians.
A descriptive observational study was performed. The study population included Spanish physicians who were asked to complete before and immediately after their guard shift the following tests: Digit Span, TMT-A, TMT-B, Symbol Digit, Stroop, Free and Cued Selective Reminding, creep and formal fluency, Visual Orientation and Space Perception tests, and the Leeds Sleep Questionnaire.
Thirty subjects were included in the study among which 43.3% were female. The mean subjective impression of the guard shift was 4.47/10 (2.57) and was correlated with the number of sleep hours during the guard shift (r = 0.72, p < 0.001). Statistically significant differences in the comparison between pre- and post-guard period results were found for the Symbol Digit test (88.27 vs. 81.47, p = 0.005), Digit Span test (7.43 vs. 7.00, p = 0.025), Free and Cued Selective Reminding Test (22.73 vs. 21.20, p = 0.002), categorical fluency (39.03 vs. 34.53, p = 0.008), and phonemic fluency (19.57 vs. 16.13, p = 0.001).
The realization of guard shift was associated with a lower yield in several cognitive functions, especially in tasks related to executive function and attention.
评估轮班后医生不同认知功能的变化。
进行描述性观察研究。研究人群包括被要求在轮班前和轮班后立即完成以下测试的西班牙医生：数字跨度、TMT-A、TMT-B、符号数字、Stroop、自由和线索选择性提醒、creep 和正式流畅性、视觉定向和空间感知测试以及利兹睡眠问卷。
研究纳入 30 名受试者，其中 43.3%为女性。轮班的主观印象平均得分为 4.47/10（2.57），与轮班期间的睡眠时间呈正相关（r=0.72，p<0.001）。在轮班前和轮班后结果的比较中，符号数字测试（88.27 对 81.47，p=0.005）、数字跨度测试（7.43 对 7.00，p=0.025）、自由和线索选择性提醒测试（22.73 对 21.20，p=0.002）、类别流畅性（39.03 对 34.53，p=0.008）和音素流畅性（19.57 对 16.13，p=0.001）有统计学显著差异。
轮班的执行与执行功能和注意力相关任务的认知功能下降有关。
