Evaluation of outpatient cancer rehabilitation for upper extremity functioning for individuals with breast cancer.

Abstract

287 Background: Specialized cancer rehabilitation is recommended for individuals with breast cancer from diagnosis throughout survivorship to mitigate the negative acute, late and lasting effects of cancer and cancer treatment on upper extremity functioning. However, evidence supporting the impact of community-based outpatient rehabilitation services is lacking, especially for older adults. Methods: Individuals with breast cancer attended cancer-specialized outpatient physical or occupational therapy provided by a single institution with multiple locations across the US in 2019, and completed the Quick DASH (Disabilities of the Arm, Shoulder and Hand). From de-identified rehabilitation records, we abstracted patient and therapy characteristics, Quick DASH scores and therapy satisfaction scores (0-10 point scale) for individuals with a history of breast cancer (identified by ICD code). We used descriptive statistics to summarize characteristics, paired samples t-tests to evaluate Quick DASH scores from initial evaluation (pre) and discharge (post) therapy, and independent samples t-test to compare mean pre-post difference for individuals younger than 65 ( < 65) versus 65 and older (≥ 65). Results: Patients ( N= 556) were 60.56 ± 12.24 (range = 31.52-89.95) years old and predominantly female ( n= 551, 99.1%). They attended cancer rehabilitation (Physical: n= 477, 85.8%, Occupational: n = 79 (14.2%)) for a median of 8 ( IQR= 5.0 – 13.0) sessions over 8.97 ± 7.57 (range = 0.71-47.7) weeks. Average pre-post change in Quick DASH score (-13.51) was significant (p < .01) and exceeded the validated minimal clinically important difference (-11.20). There was no significant difference between average pre-post change for Quick Dash scores between < 65 (n = 334, 60.1%) and ≥ 65 (n = 222, 39.9%) groups (-15.84 vs. -10.01, p = .07). Therapy satisfaction was rated high (median = 10.0, IQR = 10.0-10.0). Conclusions: Specialized rehabilitation for individuals with breast cancer was associated with statistically and clinically significant improvement in upper extremity function and high rates of satisfaction. Older adults demonstrated benefits similar to younger adults. These findings add to the growing evidence for specialized outpatient cancer rehabilitation.
