Factors Predicting and Assessment of Post Dialysis Fatigue in Patients on Regular Hemodialysis in Assiut University Hospital

To improve the quality of life of hemodialysis patients and provide better control for post dialysis fatigue in regular hemodialysis patients.

Post-dialysis fatigue (PDF) is a prevalent and debilitating symptom among patients undergoing regular hemodialysis, characterized by a persistent sense of physical and mental exhaustion following dialysis sessions This condition adversely affects patients' quality of life, daily functioning, and adherence to treatment regimens .Despite its high prevalence, PDF remains under-recognized and inadequately addressed in clinical practice. The etiology of PDF is multifactorial, encompassing physiological, psychological, and lifestyle-related factors. Recent studies have identified several predictors of PDF, including sleep disorders, the presence of comorbidities, the number of weekly dialysis sessions, and the duration of hemodialysis treatment . The symptoms and severity of PDF are evaluated using various scales. In cases of PDF, to examine the subjective symptoms of patients themselves, it is useful to utilize patient-based outcomes. However, in conventional PDF studies, the evaluation indices have not been uniform. First, in studies evaluating fatigue after dialysis based on the "time," "frequency," and "intensity" the reliability and validity of the scales were not examined. Second, the recovery time is not an index that measures PDF directly but instead an indirect indicator that measures the "time to recover from hemodialysis." Third, the fatigue scale does not measure true PDF but rather chronic fatigue experienced by dialysis patients .

in that research we use time recovery to assess post-dialysis fatigue and we use also two different fatigue scales visual analogue scale to evaluate fatigue severity and fatigue severity scale In that research we address risk factors of PDF and apply the scales on regular hemodialysis patients in hemodialysis unit of Assiut University Hospital.
