Driving after a night shift imposes a risk on health care professionals and other road users. The aim of this study was to measure psychomotor performance of driving of night shift nurses compared to day-shift nurses.
Forty-seven volunteer female nurses working at Sina hospital in Tehran, Iran, with a call in all departments of hospital, participated in this study (23 night shift and 24 day shift nurses) in 2016. The tests included RT for simple reaction time, ATAVT for perceptual speed, LVT for visual orientation and ZBA for time anticipation. Data collection tools were individual characteristics, 11-item circadian type inventory (CTI), Stanford sleepiness scale (SSS), and Swedish occupational fatigue inventory (SOFI-20) questionnaires. Psychomotor driving performance was assessed using validated computerized traffic psychological battery of Vienna Test System (VTS), before and after the shifts. Data analysis was performed using paired-samples t-test and Linear Regression.
The mean age of day and night-shift nurses were 31.4±5.6 and 28.7±3.9 years respectively, no significant difference between two groups. Thirty percent of night shift and 16.7% of day shift nurses reported traffic accidents in the past year. The results revealed that, scores based on viewing times in visual orientation test (p=0.005), and median reaction time score in choice reaction time and reactive stress tolerance test (p=0.045), had a significant association with a 12-hour night shift with a 3-hour nap.
Twelve-hour night shift work impairs choice reaction time and visual orientation in nurses, even though they take a 3- hour nap during the shift. These skills are required for safe driving.
夜班后驾车会给医护人员及其他道路使用者带来健康风险。本研究旨在对比夜班护士与白班护士的驾驶心理运动表现。
2016年，47名在伊朗德黑兰新浪医院工作的志愿女性护士参与了本研究（23名夜班护士和24名白班护士），她们来自医院各个科室。测试包括简单反应时间的反应时间（RT）、感知速度的视听反应时（ATAVT）、视觉定向的线速测试（LVT）以及时间预期的零反应时（ZBA）。数据收集工具包括个人特征、11项昼夜类型量表（CTI）、斯坦福嗜睡量表（SSS）以及瑞典职业疲劳量表（SOFI - 20）问卷。使用经过验证的维也纳测试系统（VTS）计算机化交通心理测试组在轮班前和轮班后评估心理运动驾驶表现。数据分析采用配对样本t检验和线性回归。
白班和夜班护士的平均年龄分别为31.4±5.6岁和28.7±3.9岁，两组之间无显著差异。30%的夜班护士和16.7%的白班护士报告在过去一年发生过交通事故。结果显示，视觉定向测试中基于注视时间的得分（p = 0.005），以及选择反应时间和反应应激耐受测试中的中位反应时间得分（p = 0.045），与12小时夜班加3小时午睡有显著关联。
12小时夜班工作会损害护士的选择反应时间和视觉定向，即使她们在轮班期间有3小时的午睡。而安全驾驶需要这些技能。
