Purpose
Many maintenance hemodialysis patients do not feel well after the hemodialysis session and need a time to recover. The main objective of the study was to investigate whether a simple question about the need of some time to recover from hemodialysis was associated with scores of comprehensive tools of depression symptoms and health-related quality of life (HRQOL).
Methods
Cross-sectional evaluation of 800 Brazilian patients enrolled in the Prospective Study of the Prognosis of Chronic Hemodialysis Patients (PROHEMO). The KDQOL-SF was used for HRQOL and the 20-item CES-D and BDI for depression symptoms. Linear and logistic models were used for multivariable adjustments.
Results
Patients who reported some time to recover (30 %) had significantly (P < 0.001) higher depression symptoms scores (mean difference = 4.75 for CES-D and 4.48 for BDI). HRQOL scores were, in general, lower for patients who referred a time to recover, with mean differences larger than 4.0 (P < 0.05) both for physical and mental components. Strong associations of needing a time to recover and lower scores of several kidney disease-targeted HRQOL components were also observed. Differences in depression symptoms and HRQOL were largely reduced after adjustments for symptoms (muscle pain/cramps, faintness, fatigue, nausea/vomiting).
Conclusions
The results support the validity of a simple question on post-hemodialysis recovery as a proxy for scores of complex instruments for depression symptoms and HRQOL. The results suggest that the poorer HRQOL and higher depression probability in patients who need a time to recover from hemodialysis could be partially explained by the presence of hemodialysis-related symptoms.
