To assess the impact of sleep disturbances on work performance/productivity.
Employees (N = 4188) at four US corporations were surveyed about sleep patterns and completed the Work Limitations Questionnaire. Respondents were classified into four categories: insomnia, insufficient sleep syndrome, at-risk, and good sleep. Employer costs related to productivity changes were estimated through the Work Limitations Questionnaire. Performance/productivity, safety, and treatment measures were compared using a one-way analysis of variance model.
Compared with at-risk and good-sleep groups, insomnia and insufficient sleep syndrome groups had significantly worse productivity, performance, and safety outcomes. The insomnia group had the highest rate of sleep medication use. The other groups were more likely to use nonmedication treatments. Fatigue-related productivity losses were estimated to cost $1967/employee annually.
Sleep disturbances contribute to decreased employee productivity at a high cost to employers.
评估睡眠障碍对工作表现/生产力的影响。
对四家美国公司的 4188 名员工进行了睡眠模式调查，并完成了工作限制问卷。受访者被分为四类：失眠、睡眠不足综合征、有风险和睡眠良好。通过工作限制问卷估计与生产力变化相关的雇主成本。使用单因素方差模型比较绩效/生产力、安全性和治疗措施。
与有风险和睡眠良好的组相比，失眠和睡眠不足综合征组的生产力、表现和安全性结果明显更差。失眠组使用睡眠药物的比例最高。其他组更可能使用非药物治疗。与疲劳相关的生产力损失估计每年使每位员工损失 1967 美元。
睡眠障碍导致员工生产力下降，给雇主带来高昂成本。
