Effect of acupuncture versus usual care on sleep quality in cancer survivors with chronic pain: Secondary analysis of a randomized clinical trial

BackgroundChronic pain negatively affects sleep; it is unclear whether pain relief from acupuncture contributes to sleep quality improvements in cancer survivors. This study aimed to evaluate the effect of acupuncture versus usual care on sleep quality among cancer survivors with comorbid sleep disturbance and chronic musculoskeletal pain. MethodsSleep outcome data from the Personalized Electroacupuncture Versus Auricular Acupuncture Comparative Effectiveness (PEACE) randomized clinical trial were analyzed. Electroacupuncture or auricular acupuncture was compared with usual care for sleep quality improvement over 10 weeks of treatment among cancer survivors with clinically significant sleep disturbance and chronic musculoskeletal pain at baseline. Sleep quality was measured with the Pittsburgh Sleep Quality Index (PSQI) global score. ResultsAmong 268 participants (mean [standard deviation (SD)] age, 61.4 [12.6] years; 191 women [71.3%]; mean [SD] baseline PSQI global score, 10.3 [3.3] points), electroacupuncture and auricular acupuncture resulted in greater reductions in the PSQI global score from baseline to 10 weeks in comparison with usual care: 1.42 points (95% confidence interval [CI], 0.45-2.38; p = .004) and 1.59 points (95% CI, 0.62-2.55; p = .001), respectively. The improvement in sleep quality for the acupuncture groups was sustained for 24 weeks from randomization. Furthermore, a greater proportion of patients in the electroacupuncture and auricular acupuncture groups had clinically meaningful improvement in sleep quality compared to the usual care group (41.0% and 42.9% vs. 21.4%; p = .044). ConclusionsAmong cancer survivors with comorbid sleep disturbance and chronic pain, electroacupuncture and auricular acupuncture produced a clinically relevant and persistent improvement in sleep quality. These findings suggest that acupuncture may be an evidence-based nonpharmacologic intervention to improve sleep health for cancer survivors with pain. Plain Language Summary This study analyzed the sleep quality data from a published randomized clinical trial that evaluated the effect of electroacupuncture or auricular acupuncture versus usual care on pain relief among people who survived cancer.This analysis included a prespecified subgroup of 268 participants with co-occurring sleep disturbance and chronic musculoskeletal pain at baseline and found that patients who used acupuncture for pain relief demonstrated greater improvements in sleep quality compared with patients who received usual care.Sleep quality improvement by acupuncture was sustained after the treatment ended.

Automated summary

This study analyzed the sleep quality data from a randomized clinical trial and found that acupuncture provided greater improvements in sleep quality for cancer survivors with pain compared to usual care. The improvement in sleep quality was sustained after the treatment ended.
