| Abstract: | Older adults with Hematologic Malignancy (HM) are vulnerable to functional decline secondary to disease and treatment. Interventions for physical deconditioning, in concert with routine hematology care are limited. The feasibility of accrual, retention, and demand for an exercise intervention among a high-risk HM population was piloted.MethodsOlder adults with HM, on active treatment, with functional impairment were recruited prospectively to participate in a 6-month Otago Exercise Programme (OEP). Measures of motivation, self-efficacy, patient identified barriers to exercise, barriers to clinical trial enrollment, study satisfaction, and serious adverse events were captured.Results63 patients were approached, 18 declined trial enrollment, 45 consented, 30 patients enrolled in the exercise program. The main barrier for trial enrollment was transportation/travel concerns (n = 15). Of the 45 consented participants, 8 (12.7%) dropped out due to clinical deterioration, 5 (7.9%) withdrew, and 2 (3.2%) were ineligible prior to exercise-intervention intiation. The median age was 75.5 years (range 62–83) with plasma cell dyscrasia (63%), non-Hodgkin lymphoma (20%) and leukemia (17%). Retention of the physical therapist (PT) led-OEP was 76.6% of patients (n = 23/30), and end-of-study retention was 66.7% (n = 20/30). Of the evaluable patients, 23/29 completed the PE-led OEP yielding a completion rate of 79%. Participants were extremely motivated (72.4%) and strongly intended (89.7%) to engage in regular physical activity. Exercising when tired increased from a median score of 50 at Visit 1 to 70 at Visit 2, but dropped significantly to 45 at Visit 3 (p < 0.001). Participants reported significantly lower self-efficacy to exercise over the next 6 months from Visit 1 to Visit 3 (p = 0.001).ConclusionsOlder patients with HM had higher completion of in-person, PT-led exercise compared to at-home, independent exercise. Older adults were motivated and found the program acceptable, yet the ability to sustain a structured exercise program was challenging due to changes in health status.ClinicalTrials.gov Identifier: NCT02791737 |
