Fatigue was perceived as a state of feebleness and negatively impacted individuals quality of life. maintaining normal hemoglobin levels, and acetyl-l-carnitine supplementation. Conclusion This systematic review is of value to older individuals with chronic illnesses, researchers, and clinicians who strive to improve the quality of life of individuals experiencing fatigue. To prevent undesirable consequences of fatigue, older individuals should be screened for the discussed modifiable risk factors of fatigue. The inconsistencies in the studies reviewed can guide researchers to potential research areas that require further inquiry and exploration to ground future practice on best scientific evidence = 54Evaluate the effect of epoetin alfa treatment on hemoglobin, fatigue, quality of life, and mobility in elderly patients with chronic anemiaFACIT-AnEkman & Ehrenberg (2002), SwedenDescriptiveChronic heart failureWomen: 83= 158Describe and compare the experience of fatigue in a group of elderly women and men with severe chronic heart failureModified version of Fatigue Interview Schedule= 83Objectively measure chronic fatigue and identify factors that contribute to its occurrence in older adultsCFSH?gglund et al.

Summary This systematic examine is of worth to older people with persistent illnesses, analysts, and clinicians who make an effort to improve the standard of living of individuals encountering exhaustion. To prevent unwanted consequences of exhaustion, older individuals ought to be screened for the talked about modifiable risk elements of exhaustion.
