Poor sleep and sleepiness in the workplace are associated with accidents. A workplace sleep health promotion program was implemented in an Italian police unit. Of the 242 police officers in the unit, 218 (90%) agreed to take part in the program. A crossover trial was made in which the police officers were divided into two groups that performed sleep health promotion activities in the first and second year, respectively. The first group of officers showed significant sleep improvements at the end of the first year, while the second group had similar or worse parameters than at baseline. At follow-up, a significant improvement in the quantity and quality of sleep was reported in both groups. Sleep improvements at follow-up were associated with a marked reduction in the frequency of accidents at work and near-misses. Before the intervention, sleepiness was the best predictor of injuries (aOR 1.220; CI95% 1.044-1.426) and near-misses (aOR 1.382; CI95% 1.182-1.615). At follow-up, when sleep conditions had improved, insomnia symptoms were the most significant predictors of work accidents (aOR 13.358; CI95% 2.353-75.818). Sleep health promotion can be useful in police officers.
工作场所的睡眠不佳和嗜睡与事故有关。在一个意大利警察部门实施了一项工作场所睡眠健康促进计划。该部门的 242 名警察中，有 218 名（90%）同意参加该计划。进行了一项交叉试验，将警察分为两组，分别在第一年和第二年进行睡眠健康促进活动。第一组警察在第一年结束时睡眠质量显著改善，而第二组的参数与基线相比相似或更差。随访时，两组的睡眠质量和数量都有显著改善。随访时的睡眠改善与工作和险些事故的频率明显减少有关。干预前，嗜睡是受伤（aOR 1.220；CI95% 1.044-1.426）和险些事故（aOR 1.382；CI95% 1.182-1.615）的最佳预测指标。随访时，当睡眠状况改善时，失眠症状是工作事故的最显著预测指标（aOR 13.358；CI95% 2.353-75.818）。睡眠健康促进对警察有用。
