AI Article Synopsis
- The study investigated the relationship between sleep patterns and psychomotor vigilance in female nurses, comparing night nurses to day nurses over three days.
- Results showed that night nurses had significantly less sleep, averaging about 4 hours less than day nurses, and experienced more variability in their sleep duration, while also reporting increased sleepiness after work.
- The findings highlight the negative effects of shift work on sleep quality and alertness, suggesting a need for further research on sleep interventions for nurses working irregular hours.
Article Abstract
The purpose of this study was to evaluate the relationships between sleep and psychomotor vigilance in female nurses and the changes in these variables over time. Participants comprised 16 staff registered nurses (10 day, 6 night; aged 30-65 years [M = 47.6; SD = 8.1]) who wore wrist actigraphs continuously and completed a 10-min psychomotor vigilance test (PVT-192, Ambulatory Monitoring, Inc., Ardsley, New York) and the Stanford Sleepiness Scale (SSS) in their homes before and after work for three consecutive 24-hr periods. Repeated measures ANOVA revealed that night nurses slept significantly less than day nurses, F(1, 15) = 26.06, p ≤ .001; M = 227.88 ± 37.03 min versus M = 365.75 ± 59.01 min, respectively, daily for three consecutive days. Night nurses napped more frequently and had more changes in the length of their main sleep periods than day nurses. Day nurses reported more wake episodes during main sleep periods. Night nurses were sleepier after work than day nurses; both groups had increased sleepiness after work for the first 2 days and similar psychomotor vigilance test results. These findings suggest that sleep deprivation, irregular sleep patterns, and sleepiness are significant issues for shiftworking nurses. Future study of the characteristics of sleep and sleepiness in a larger sample would be useful to evaluate the focus for interventions to improve sleep and alertness in shiftworking nurses.

Background: Neonatal advanced practice providers (APPs) often work prolonged hours in high-acuity neonatal intensive care units (NICUs). It is imperative to understand how fatigue affects the APP's ability to react quickly following long shifts. There is a lack of data on the effects of shift length and fatigue on neonatal APP job performance and clinical decision-making.

Purpose: The psychomotor vigilance task (PVT) is one of the main methods to measure sustained vigilance/attention in sleep research. Vigilance is the main factor affecting daytime function in patients with narcolepsy type 1 (NT1). We aimed to quantify the negative effects of sleep-wake disorders on vigilance and investigate potential neural mechanisms.

Three experiments with the psychomotor vigilance task examined whether presenting content-free cues, feedback, and points would reduce lapses of sustained attention. In all three experiments, behavioral lapses of attention (particularly slow reaction times) were reduced with the motivation manipulations compared with control conditions, but self-reports of off-task thinking (e.g.

In obstructive sleep apnea (OSA), heart rate variability (HRV) decreases and performance in psychomotor vigilance task (PVT) worsens with more severe hypoxic load. Nevertheless, the association between HRV and PVT performance is poorly understood. Thus, we hypothesize that nocturnal short-term HRV is better related to daytime psychomotor vigilance compared to overnight HRV.
