Insights
Fatigue in chronic hemodialysis (HD) patients is significantly linked to apathy and reduced daily functioning. Apathy, not depression, emerged as a key predictor of fatigue severity in these individuals.
Area of Science:
- Nephrology
- Psychiatry
- Quality of Life Research
Background:
- Chronic hemodialysis (HD) patients frequently experience fatigue, impacting their quality of life.
- The relationship between fatigue and psychological factors like apathy requires further investigation in this population.
Purpose of the Study:
- To investigate the association between fatigue and apathy in patients undergoing chronic hemodialysis.
- To identify predictors of fatigue severity, including apathy, depression, and functional status.
Main Methods:
- 139 chronic HD patients were assessed using validated scales for fatigue (Fatigue Severity Scale - FSS), apathy (Apathy Evaluation Scale - AES), and depression (Beck Depression Inventory - BDI).
- Functional status was evaluated using Activity of Daily Living (ADL) and Instrumental Activity of Daily Living (IADL) scales.
- Correlations and multiple regression analyses were performed to determine relationships between variables.
Main Results:
- Higher FSS scores correlated with lower ADL and IADL scores, higher BDI and AES scores, and lower serum creatinine levels.
- Fatigue Severity Scale (FSS) demonstrated strong correlations with Apathy Evaluation Scale (AES) and Beck Depression Inventory (BDI).
- Apathy and IADL were identified as independent predictors of fatigue in the HD population via multiple regression analysis.
Conclusions:
- Apathy is significantly associated with fatigue in chronic HD patients.
- Apathy and reduced functional capacity (IADL) are key independent predictors of fatigue.
- Further longitudinal research is recommended to explore if apathy is a causal factor in fatigue development in HD patients.
Introduction:
This study explores the link between fatigue and apathy in patients on chronic hemodialysis (HD).
Methods:
One hundred thirty-nine chronic HD patients underwent the assessment of fatigue, apathy, depression, and their functional status, with the fatigue severity scale (FSS), the Apathy Evaluation Scale (AES), the beck depression inventory (BDI), the activity of daily living (ADL), and instrumental activity of daily living (IADL).
Results:
Patients with high FSS had a significantly lower ADL and IADL score, higher BDI, Charlson Comorbidity Index, and AES score, and lower serum levels of creatinine, compared to low FSS patients. FSS was highly correlated with the AES, as well as with the BDI and the AES correlates with the BDI. At multiple regression analyses, only apathy and IADL were independent predictor variables of fatigue in HD population.
Conclusion:
Future longitudinal studies could determine if apathy is a causative factor for fatigue manifestation and development in HD patients.
