Kozik, T.M., Hickman, M.C., Schmidt, S., Connolly, T.F., Paustenbach, K., Vosti, P., & Bhattacharyya, M. (2018). An exercise program to improve depression and sleep disorders in oncology patients: The SAD study. European Journal of Oncology Nursing, 37, 19–22.
To evaluate the effect of a structured supervised outpatient exercise program on insomnia and depression in patients with cancer.
Patients were referred by their oncologist office to the program. Participants were consented, administered two instruments before and after, and then participated in a 90-minute structured, supervised exercise program two days per week. The exercise consisted of a warm-up, cardiovascular circuit training, strength training, and cool down. The program was for 10 weeks.
PHASE OF CARE: Active anti-tumor treatment
75 patients were enrolled and 40 completed the 10-week program. The study demonstrated a significant improvement in insomnia. Baseline scores (mean = 9.5; SD = 3.7) compared to final scores (mean = 6.3; SD = 3.5) showed (t = 4.468; p = 0.01). The significance level of 0.05 is over the 90%. The depression scores were also seen as significantly different from baseline (mean = 37.4; SD = 9.7) and final scores (mean = 33; SD = 9.7) (t = 2.427; p = 0.01). The significance of 0.05 is about 80%. The study team also evaluated those who did not complete the program and there was no difference. Depression scores at baseline were higher for those who did not complete the program.
This study showed improvement in depression and insomnia in patients with cancer who participated in a structured, supervised exercise program.
Nurses should assess patients for insomnia and depression and provide appropriate referrals to structured exercise programs. The cost is low and many cancer centers have existing exercise programs for fatigue which could be combined with the mental health benefits. Nurses could encourage and participate in development of these programs with their healthcare and community fitness centers where none currently exist.
