A prospective study of fatigue trajectories among in-centre haemodialysis patients.

Damage beliefs predicted an increase in fatigue-related functional impairment over time. However, the data strongly suggested that fatigue outcomes vary by length of time on dialysis. Statement of contribution What is already known on this subject? At least 1 in 2 haemodialysis (HD) patients are clinically fatigued. Growing evidence is available on the important role of psychological factors in fatigue across chronic conditions. The contribution of psychological factors, beyond distress, to fatigue in HD has not been examined to date. What does this study add? Ethnicity played a role in the initial level of fatigue severity and over time. Damage beliefs predicted an increase in fatigue-related impairment over time. Data strongly suggested that fatigue outcomes vary by length of time on dialysis.
