Determinants of sleep quality and fatigue in patients undergoing hemodialysis

Aim: This research aimed to evaluate sleep quality and fatigue among individuals undergoing hemodialysis and to explore the determinants affecting these variables. Methods: This observational investigation was carried out among 78 who were regularly receiving hemodialysis therapy. The research was carried out between May and October 2025 in three different public hospitals among individuals undergoing hemodialysis treatment. Data were gathered using the Patient Information Form (PIF), the Fatigue Severity Scale (FSS), and the Pittsburgh Sleep Quality Index (PSQI). Results: The mean score of the hemodialysis patients on the FSS is 4.97 ± 1.11, and the mean PSQI value is 7.76 ± 3.64. A moderately positive and statistically noteworthy relation was observed between the PSQI and FSS scores. Additionally, a low negative meaningful correlation was seen between ferritin levels and the FSS scores, as well as between calcium levels and the PSQI scores. The use of medications related to chronic disease and the PSQI scores were identified as significant predictors of the FSS scores. Conclusion: Fatigue and sleep quality in individuals receiving hemodialysis treatment are related to each other, as well as to biochemical balance and treatment adherence.
