Rehabilitation intervention safety in patients with malignant lymphoma with low blood cell counts.

[Purpose] We established criteria for patients with malignant lymphoma with low blood counts, who did not meet the criteria to discontinue rehabilitation or the blood transfusion criteria even though they were borderline for discontinuing rehabilitation. We investigated physical symptoms, activities of daily living, and adverse events in patients who were permitted to undergo rehabilitation intervention using the new criteria. [Participants and Methods] Forty-two patients met the criteria to discontinue rehabilitation based on blood data, and the new-criteria group included 153 patients who received permission for rehabilitation from a hematologist despite not meeting the criteria to discontinue rehabilitation. The survey items were Barthel index at the time of admission and discharge and the length of hospital stay. A two-group comparison was performed, and the occurrence of adverse events associated with exercise intervention were investigated. [Results] The length of hospital stay was shortened in the new-criteria group, and the rehabilitation intervention rate improved. [Conclusion] For patients with malignant lymphoma with low blood cell counts, continuing rehabilitation intervention with physician permission may prevent a decline in activities of daily living as well as maintain and improve motor function.
