Abstract

socio-economic burden based on the aging society. Although the main goal of HF treatment is to alleviate symptoms and signs, many patients complain of poor sleep quality. It is known that poor sleep quality of patients with HF results in decreased quality of life, impaired function and increased readmission. However, there is the lack of the results regarding sleep quality and factors affecting sleep quality in Koreans with HF. Purpose: The purpose of this study was to examine the factors that influence the quality of sleep in patients with HF. Methods: This study was a descriptive study and data was collected from 120 patients in out patient clinic, S hospital, Seoul. General characteristics, clinical characteristics and psychological features were measured. Quality of sleep was measured using the Pittsburgh Sleep Quality Index, depression was measured by the Centers for the Epidemiological Studies of Depression Scale, and the beliefs and attitudes of sleep dysfunction were measured by the Dysfunctional Beliefs and Attitudes about Sleep Scale-16. Data was analyzed using descriptive statistics, chi-square, t-test and logistic regression analysis. Results: 62.5% of the subjects were found to have poor sleep quality. The average sleep time was 5.81 hours, which complained of sleep problems in the order of the sleep latency, subjective sleep quality, and sleep disturbances. There were statistically significant differences in sleep quality between the current occupational status(p=0.006), NYHA Class(p=0.011), Depression(p=0.001), Perceived health status(p<0.001), and Dysfunctional Beliefs and Attitudes about Sleep(p=0.007). The probability that the unemployed group increased the probability of poor sleep quality by 3.026 times compared to the group with the current occupation, and the probability that the quality of sleep was worse as the depression increased by one point increased by 1.062 times. Conclusions: The quality of sleep in heart failure patients was poor and affected by current job conditions and depression. To improve patients’ quality of sleep, it seems to be needed to improve the level of clinical symptoms, reduce depression, and improve perceived health status and the dysfunctional beliefs and attitudes about sleep in patients with HF.
