Factors affecting the performance of activities of daily living in patients with advanced cancer undergoing inpatient rehabilitation: results from a retrospective observational study

[Purpose] Many clinicians believe that rehabilitation for patients with advanced cancer is futile. We determined factors affecting the performance of activities of daily living in patients with advanced cancer based on age, gender, marital status, living arrangement, rehabilitation intensity, type of cancer, impairment, metastasis, and active cancer treatment. [Participants and Methods] We assessed the Barthel Index to evaluate the performance of activities of daily living. Of the 120 adult patients with cancer who underwent inpatient rehabilitation, we analyzed the Barthel Index scores, consisting of 10 items, and reviewed the clinical characteristics from the medical records of 48 patients who completed supportive or palliative rehabilitation according to Dietz and showed an increased or maintained total Barthel Index score at final evaluation. [Results] The median total Barthel Index score increased from 45 (5–95) to 72.5 (5–100); the rehabilitation intensity was 320 (40–1,240) minutes. The analytical results showed that the increase of total Barthel Index score was positively associated with rehabilitation intensity (β=0.350) and negatively associated with the initial grooming score (β=−0.277). [Conclusion] Adequate rehabilitation positively affects performance of activities of daily living, especially in patients with advanced cancer who lost their grooming ability at the onset of rehabilitation. Importantly, rehabilitation may be beneficial for patients with advanced cancer.
