How many monthly nighttime-sleep opportunities are optimal for recovery from fatigue among shift-working nurses? A 1-month sleep log observational study to test anchor nighttime sleep in Japan

| description | Background Given that nighttime sleep has more recuperative power than daytime sleep, ensuring the former is important to recovery from work, especially for shift-working nurses. In this 1-month sleep log study, we preliminarily examined how the number of monthly nighttime-sleep opportunities relates to fatigue-related outcomes among shift-working nurses.Methods 526 nurses were required to record their daily sleep duration immediately after waking from sleep for 1 month. We analysed the associations among the four sleep groups (ie, ≤ 12, 13–19, 20–24 and≥24 nighttime-sleep opportunities per month) and fatigue-related outcomes. A one-way analysis of covariance or generalised linear mixed model (factor: sleep group) was conducted using R (version 4.2.2.) to test the association.Results Significant differences among the four sleep groups were obtained using the excessive fatigue symptom inventory (EFSI), Pittsburgh sleep quality index (PSQI) and the numbers of near-miss incidents. Moreover, significant linear trends were observed in the EFSI and PSQI scores.Conclusions Shift-working nurses who experienced 12 or fewer monthly nighttime-sleep opportunities showed worse fatigue-related outcomes than those who had sufficient monthly nighttime-sleep opportunities. Therefore, more attention should be paid to ensuring monthly nighttime-sleep opportunities when creating a shift schedule. |
