Background and Objective: Fatigue or inattentiveness in nurses during shift work affects patient safety. Therefore, sleep quality and alertness during shift work requires monitoring. The aims of this study were to: 1) compare sleep parameters measured using sleep logs and mobile sleep applications and 2) evaluate sleep quality and alertness during shift work using mobile applications.
Methods: Twenty shift-work nurses voluntarily enrolled in the study. We compared sleep parameters including time in bed (TIB), sleep latency (SL), total sleep time, and wakefulness after sleep onset, recorded using sleep logs and mobile applications. An additional 66 female shift-work nurses voluntarily evaluated their sleep quality and alertness at work using the ‘Sleep Time’ and ‘Math Quiz’ applications.
Results: TIB was significantly lower in night-shift nurses (328.3 ± 8.9) than in nurses working other shifts (395.3 ± 9.1 min; p < 0.05). SL was significantly lower after a night shift (26.1 ± 1.7 min; p < 0.05) than after a day shift (31.5 ± 1.9 min) or a day off (31.0 ± 1.4 min). The Math Quiz scores did not vary by shift type, but sleepiness scores were significantly higher immediately after waking up (5.57 ± 0.15) and during work (4.91 ± 0.14) in night-shift nurses, as compared to other nurses (p < 0.05).
Conclusions: Mobile applications and sleep logs were both effective in measuring sleep parameters. Most shift-work nurses, particularly those working nights, slept poorly. Mobile sleep and arithmetical applications are objective, reliable, and feasible means of monitoring the sleep quality and alertness of shift-work nurses.
