The prevalence of portable media device (PMD) use has proliferated, potentially causing serious problems, particularly in critical situations. The main aim of the present study was to investigate the relationship between pre-sleep PMD use and cognitive performance, as well as the mediating effects of sleep quality among nurses. A cross-sectional study was designed, with 200 registered nurses voluntarily participating. The average time spent on PMDs was self-reported. The Pittsburgh Sleep Quality Index, the epworth sleepiness scale, the Occupational cognitive failures questionnaire, and the Nursing Errors Questionnaire were used to collect data. Correlation analyses and structural equation modeling were conducted. Significant relationships were found between pre-sleep PMD use and all variables of interest. Sleep quality was significantly related to daytime sleepiness and occupational cognitive failures, mediating the effect of pre-sleep PMD use on these two variables. Problematic use of PMDs at bedtime may be considered an unsafe act for healthcare workers. Healthcare providers should be aware of the potential risks induced by excessive PMD use. Creating a culture of proper smartphone use is crucial for overcoming these challenges.
便携式媒体设备（PMD）的使用已经普及，可能会导致严重的问题，特别是在危急情况下。本研究的主要目的是调查护士睡前使用 PMD 与认知表现之间的关系，以及睡眠质量在其中的中介作用。采用横断面研究设计，200 名注册护士自愿参与。PMD 的平均使用时间由自我报告。匹兹堡睡眠质量指数、埃普沃斯嗜睡量表、职业认知失误问卷和护理差错问卷用于收集数据。进行了相关分析和结构方程建模。睡前使用 PMD 与所有感兴趣的变量之间存在显著关系。睡眠质量与日间嗜睡和职业认知失误显著相关，中介了睡前 PMD 使用对这两个变量的影响。睡前使用 PMD 可能被视为医疗保健工作者的不安全行为。医疗保健提供者应该意识到过度使用 PMD 带来的潜在风险。营造正确使用智能手机的文化对于克服这些挑战至关重要。
