Fatigue and functional outcomes in cancer rehabilitation.

purposeCancer-related fatigue (CRF) is one of the most common symptoms experienced by oncology patients, though its impact on functional outcomes during inpatient rehabilitation is relatively unknown. The purpose of this study is to determine whether CRF severity on admission is related to functional gains following standard rehabilitation care in an inpatient oncology rehabilitation population.

methodsA retrospective cohort study was conducted within an inpatient oncology unit at a long-term acute care hospital. Seventy-six patients admitted to the hospital between April and December 2015 with an oncology diagnosis, planned discharge, and completed standardized assessments of CRF and functional ability were included in this study. Patients received standard interdisciplinary rehabilitation services including physical and occupational therapy. CRF was assessed on admission using the Brief Fatigue Inventory, and functional abilities were assessed on admission and discharge using the basic mobility and daily activity domains of the Activity Measure for Post-Acute Care inpatient short forms (AM-PAC).

resultsNinety-seven percent of patients reported CRF, and 57% reported severe CRF upon admission. Patients demonstrated on average a 30% and 14% reduction in functional impairment in basic mobility and daily activity respectively during their admission. There was no significant correlation found between CRF on admission and change in functional impairment.

conclusionThis study contributes to existing literature in that it found patients who received inpatient rehabilitation services demonstrate significant improvement in their functional status despite reporting CRF upon admission to a long-term acute care hospital oncology unit.
