Purpose : The purposes of this study are to examine the quality of sleep among patients that were admitted in the thoracic surgery department and received a surgery and check the factors influencing their quality of sleep. Methods : The subjects include 131 adult patients that were admitted in the thoracic surgery department at P University Hospital in B City, received a thoracic surgery, and spent three days in hospitalization after the surgery. Data was collected with a questionnaire on February 1 ~ April 30, 2019. Research instruments employed in the study include the sleep measuring tool A to measure the quality of sleep, the Visual Analogue Scale(VAS) to measure pain, the Korean Activities of Daily Living(K-ADL) to measure the degree of daily life activities, and the Hospital Anxiety and Depression Scale(HADS) to measure anxiety and depression. Collected data was put to the frequency, percentage, mean, standard deviation, T-test, ANOVA, Scheffe's test, Pearson's correlation analysis, and stepwise regression analysis with the IBM SPSS 25.0 program. Results : The subjects recorded mean 37.45±8.01 points in quality of sleep. Of their general characteristics, only hospitalization experiences were significant(t=-2.257, p=.026). Of surgery characteristics, sleep of quality differed according to the part of surgery(F=3.755, p=.013), days of hospitalization in the intensive care unit(F=5.641, p=.004), use of an anticoagulant(t=-2.024, p=.045), use of a sleeping pill(t=-2.017, p=.046), and days of hospitalization at the hospital(F=6.018, p=.003). Their quality of sleep had significant negative correlations with the activities of daily living scores(r=-.336, p<.001), pain(r=-.264, p=.002), anxiety(r=-.407, p<.001), and depression(r=-.423, p<.001). As factors influencing the quality of sleep, depression(β=-.25, p=.004), anxiety(β=-.28, p=.001), pain(β=-.18, p=.017), and hospitalization experiences(β=-.16, p=.036) had a negative regression coefficient and thus had negative impacts on quality of sleep. These variables had explanatory power of 27.8%. Conclusion : These findings raise a need to develop methods and programs for nursing interventions to increase quality of sleep based on effective interventions for patients that are hospitalized in the thoracic surgery and receive a thoracic surgery according to the factors influencing quality of sleep.
