| Summary: | 碩士 === 國立臺北護理健康大學 === 護理研究所 === 101 === The purpose of this study was to describe the peritoneal dialysis patients’ sleep quality and its influencing factors. The study was a cross-sectional descriptive and correlational research design. Data were collected by using the study questionnaire, including questions on demogarphics and disease characteristics, Center for Epidemiologic Studies depression Scale, Pittsburgh Sleep quality Scale, 5-D Itching Scale, and Physical Activity Scale for the Elderly. A convenience sample of 160 patients undergoing long term peritoneal dialysis were recurited from peritoneal dialysis clinics in a medical center at northern Taiwan.Data were collected from 4th June to 6th July in year 2012. Data were analyzed for 157 patietns who have completed the study questionnaire. Descriptive statistics , independent T-test, one-way ANOVA, Pearson's product moment correlation and multiple regression were used to analyze patients’ sleep quality and its related factors.
The study result showed that 68.2% of the sample suffered poor sleep quality（score more than 5）. The average score of the peritoneal dialysis patients’ sleep quality was 8.10±4.04 measured with Pittsburgh Sleep Quality Index. Regarding the demogrphics and disease variables, only the duration of peritoneal dialysis and using sleeping pills related to the patietnss sleep quality. The patients who had longer duration of receiving peritoneal dialysis and taking sleeping pills showed worse sleep quality. The patietns’ sleep quality were also correlated with the severity of depression and pruritus. The greater the severity of depression and pruritus, the worse sleep quality of the patient. Results of stepwise multiple regression analysis showed that depression, pruritus, smoking and using sleeping pills were significant predictors of sleep quality. These four variables togather can explain 32.2 percent of the varance in patients’ sleep quality.
The study reulsts showed that sleep quality of peritoneal dialysis patient was highly correlated with depression and pruritus. Because depression is easily to be overlook, therefore clinicians should carefully assess depressive symptoms in this population and provide timely referral for who showed depression problems. Pruritus was also an signifiant predictor for bad sleep quality. Therefore, to improve the depression and pruritus may be able to improve peritoneal dialysis patients’s sleep quality.
