PURPOSE: The purpose of this study was to identify the factors influencing fatigue in patients with chronic obstructive pulmonary disease. METHODS: A descriptive correlational study design was used. A convenience sample of 125 subjects was recruited from the outpatient respiratory clinic at a large university hospital. Data was collected from June to October, 2005 using structured questionnaires, an oxygen saturation test, a 6-minute walking test, and a pulmonary function test. RESULTS: Subjects had a slightly low degree of fatigue. The fatigue showed a significant correlation with emotion(r= .589, p= .000), dyspnea(r= .304, p= .001), self-efficacy (r= -.278, p= .002), and symptom experience(r= .238, p= .008). Emotion(34.7%) and dyspnea(5.8%) were significant predictors to explain fatigue. CONCLUSION: This study provides comprehensive understanding of the influencing factors on fatigue in patients with chronic obstructive pulmonary disease. Nursing interventions to decrease negative emotion and dyspnea for management of fatigue is suggested.

PURPOSE: This study examined the characteristics of fatigue and the relationship between fatigue and its related factors in Korean patients on hemodialysis. METHODS: A cross-sectional correlational study was conducted with 104 patients on hemodialysis in Seoul, Korea. FINDING: Of a total of 104 subjects, eighty-one (77.9%) complained of fatigue. Fatigue severity was measured by the self-rating Visual Analogue Scale-Fatigue (VAS-F) with a mean score of 36.5 (SD=17.49, range 2 - 81). The mean duration of fatigue was 3.8 hours (SD=5.3, range 0 - 24). Depression was most significantly correlated with fatigue (beta=.43, p<.00), with interdialytic weight gain (beta=.25, p<.05) being the second most significant correlate. CONCLUSION: This study shows that nursing interventions for patients who experience fatigue while on hemodialysis should be focused on both psychological problems, such as depression, as well as on physiological problems, such as interdialytic weight gain.
