Multiple Dimensions and Correlates of Fatigue in Individuals on Hemodialysis.

This study examined the severity, pattern, and correlates of fatigue among adults undergoing hemodialysis. Measures included the Piper Fatigue Scale (PFS-12), Patient-Reported Outcomes Measurement Information System (PROMIS) - Fatigue, Charlson Comorbidity Index, and Six-Minute Walk Test (6MWT). Patients were excluded if mobility or cardiovascular issues prevented conducting the 6MWT. Participants were 86 cognitively intact adults (M = 61.7 years, SD = 13.81), predominantly male (58.1%), and African American (48.8%), with 80% reporting fatigue in the week prior to hemodialysis. Significant increases were noted in sensory and cognitive fatigue from pre- to post-dialysis, while the 6MWT distance decreased significantly pre- to post-dialysis. Factors significantly associated with pre-dialysis fatigue included low hemoglobin, younger age, and living with someone else, while comorbidities and dialysis inadequacy were trending to significant associations with fatigue.
