Langford, D. J., Lee, K., & Miaskowski, C. (2012). Sleep disturbance interventions in oncology patients and family caregivers: a comprehensive review and meta-analysis. Sleep Medicine Reviews, 16, 397–414.doi: 10.1016/j.smrv.2011.07.002
To synthesize findings from intervention studies for sleep disturbance in patients with cancer and their caregivers.
Intervention groupings analyzed via meta-analysis included cognitive-behavioral therapy (CBT), education, exercise, and complementary and alternative therapies. Effect sizes appeared to be slightly over 1.0 for CBT, close to 0 for education, slightly over 1.0 for exercise, and slightly over 0 for complementary and alternative therapies. Specific effect sizes were only shown graphically, and actual data were not presented. No separate analysis of caregiver effects could be determined. Modes of delivery of interventions varied widely across studies.
Findings suggest at least moderate effects of CBT and exercise for improvement in sleep disturbances for patients with cancer. No substantial effects of exercise and education were demonstrated.
The review was limited by the lack of any data regarding heterogeneity in the meta-analysis, variability of interventions, and modes of delivery to enable any firm conclusions.
Insufficient evidence was provided to draw any conclusions regarding intervention effects for caregivers.
