Abstract

|
|
Objectives: Nurses working in a hospital operate in a special environment where patients require a 24-hour day service. In order to meet the need for manpower, nurses in the wards, ICU, and ER work in 3 shifts per day. This study was designed to evaluate their sleeping patterns and the factors that influence them.
Methods: The subjects were 114 female nurses working at a University Hospital in Kyungi-do. To evaluate their sleeping pattern, a survey containing 11 questions was used. Their were differentiated into insomnia, sleep deprivation, daytime sleepiness, and snoring. Statistical analysis was conducted with independent t test, chi - square test and analysis of covariance.
Results: A statistical difference was found between shiftworkers and nonshiftworkers, in terms of sleep initiation time (p<0.05). The occurrences of insomnia, sleep deprivation, daytime sleepiness and snoring differed between the two groups, but not significantly.
Conclusions: Of the numerous factors affecting sleeping patterns, shiftwork has the most deteriorative effect.
