Abstract:
Introduction:5-10% of shift workers experience severe shift insomnia and sleepiness. A nurse specialist stays by
the client's side 24 hours a day, assesses and monitors their physical condition, and provides nursing
care. In a comparative study on the work activity among shift nurses, night shift nurses were less
active (40%) and more fatigued (53.3%) than day shift nurses.
An aspects of chronotype and sleep quality in shift nurses does not established in Mongolia and the
data is very rare, and we aimed to conduct this study.
Goal:To study shift schedule, sleep quality and individual chronotype of shift nurses.
Materials and Methods:This study is a cross-sectional study. The survey was completed between July 1, 2023 and December
31, 2023, and included a total of 117 nurses who met the inclusion and exclusion criteria of the BZDGH,
SKDGH, and KUDGH research. In collecting research data, the questionnaires "Insomnia Severity
Index", which is a commonly used international standard questionnaire for assessing insomnia, The
Munich Chrono Type Questionnaire for assessing individual chronotype, and "Karolinska Sleepiness
Scale" were used.
The ethical approval:The ethical approval for the study was obtained by a decision of the Ach Medical University-Ethical
Committee on Research on June 30, 2023 (2023/02/05).
Statistical analysis :Results were calculated using SPSS - 21.0 v program by a descriptive statistic, and the Pearson
correlation analysis.
Results :The average score of the Insomnia Severity Index (ISI) was 12.60±6.38, which is the sub threshold
for clinical insomnia. But the average Karolinska Sleepiness Scale (KSS) score for sleepiness is
4.41±2.50, or moderate alertness during the shift. Workday sleep-wake pattern and non-workday
sleep-wake pattern are correlated (r=0.44, p=0.001). Also, individual chronotype is correlated with
chronotype of non-working days (r=0.23, p=0.02).
Conclusions:Nurses' sleep quality levels were pre-clinical insomnia and moderate alertness during shifts for sleepiness.
Working and non-working day sleep-wake patterns are different, chronotype is medium early type. The
sleep-wake pattern of weekdays and the sleep-wake pattern of non-workdays are related to each other.
The chronotype of the individual is related to the chronotype of non-working days.
