Functional outcomes and oncological fatigue among older cancer patients: a cross-sectional study

ABSTRACT

Abstract Aim: To characterize functional outcomes and oncological fatigue in older cancer patients, and verify the relation of these outcomes with age, number of hospitalizations, and falls within 12-months. Methods: Cross-sectional study involving 116 older adults with cancer undergoing treatment in a hospital in Santiago de Chile. Participants were assessed for independence on the activity of daily living (Barthel index), functional mobility with "timed up and go" (TUG) test, handgrip strength with a Baseline® Hydraulic Hand Dynamometer, and fatigue with Brief Fatigue Inventory. Information about the number of falls and hospitalizations from the previous 12-months was also collected. Results: 21.6% had experienced at least one fall during the previous 12-months, and 52% had been hospitalized over the same period. Handgrip strength was below the cut-off thresholds for older adults and 78.4% were classified with the risk of falls according to the TUG test. Forty-nine percent of participants experienced moderate fatigue, and 58% were dependent to perform activities of daily living. There was a correlation of TUG results with age (r = 0.204; p = 0.028). Conclusions: Older adults with cancer in our study experienced moderate fatigue, a high dependence to perform activities of daily living, especially those associated with mobility, dressing, and bladder or bowel function. Older adults with cancer are more likely to develop functional decline which leads to increased dependency or death. The data suggests they present functional impairment. Physical activity interventions would benefit this population.
