Fatigue by the Chalder Questionnaire and post-hemodialysis recovery in a population of predominantly African descent: The PROHEMO.

A high prevalence of fatigue and a positive association between fatigue and post-hemodialysis recovery have been reported in predominantly white populations of maintenance hemodialysis (MHD) patients. The present study evaluates associations between self-reported fatigue by the 11-item Chalder Fatigue Questionnaire (CFQ-11) and the need for post-hemodialysis recovery in a predominantly African-descent MHD population.A total of 233 patients (94% Black or Mixed-Race) participating in the "Prospective Study of the Prognosis of Patients on Maintenance Hemodialysis" (PROHEMO), Salvador, Brazil were recruited for this cross-sectional study. The CFQ-11 was used to measure fatigue: <4 for absent or mild, ⩾4 for moderate to severe. Patients were also asked if they needed some time to recover after the hemodialysis. Logistic regression was used to estimate odds ratio (OR) of the association with adjustments for age, sex, race, educational level, economic class level, diabetes, hearth failure, and hemoglobin.Mean age was 51.5 ± 12.5 years. Moderate to severe fatigue (⩾4 points) was observed in 70.8% (165/233), and absent or mild fatigue (<4 points) in 29.2% (68/233). Compared to patients with fatigue scores <4 (20.6%), the need for post-hemodialysis recovery was 2.5 times greater in patients with fatigue scores ⩾4 (52.7%). The covariate-adjusted logistic regression OR was 4.60, 95% CI: 2.27, 9.21.This study in MHD patients of predominantly African descent supports self-reported fatigue assessed by the CFQ-11 as a relevant predictor of the need for post-hemodialysis recovery. The results offer a rationale for investigating whether interventions to prevent fatigue reduce the need of post-hemodialysis recovery.
