Understanding the Use of Acupuncture for Insomnia Among Cancer Survivors: A Qualitative Study

Efficacy of acupuncture treatment for breast cancer-related insomnia: study protocol for a multicenter randomized controlled trial

Background

Insomnia is one of the most common symptoms among breast cancer patients, which can be present throughout all stages of breast cancer. As a non-pharmacological alternative treatment, acupuncture has been suggested to improve sleep situations in patients with cancer suffering from insomnia. However, there is a lack of well-designed, high-quality clinical evidence regarding the efficacy of acupuncture in the treatment of breast cancer-related insomnia. This study is conducted to evaluate the efficacy and safety of acupuncture treatment for breast cancer-related insomnia.

Methods

This study was designed as a multicenter, randomized, sham-controlled clinical trial. A total of 264 eligible patients with breast cancer-related insomnia will be randomized into an acupuncture group and a sham acupuncture group in a 1:1 ratio. In the trial, patients in the acupuncture and sham acupuncture groups will receive 12 sessions over a consecutive 4-week period. The primary outcome will be the treatment response rate of Insomnia Severity Index (ISI) at week 4; secondary outcomes include treatment remission rate of ISI, Sleep Efficiency (SE) obtained by the use of Sleep diary, treatment response rate of ISI at 8th and 16th weeks of follow-up, the mean changes of ISI, Generalized Anxiety Disorder Scale (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Quality of Life Questionnaire - Core 30 (QLQ-C30), sleep parameters recorded in Actigraphy and weekly usage of remedial drugs. Adverse events will be recorded throughout the study. All analyses will be based on the ITT principle and performed with SAS 9.4 statistical software.

Discussion

This trial will evaluate the clinical efficacy and safety of acupuncture for breast cancer-related insomnia. If proven effective, acupuncture will provide an effective option for patients with breast cancer-related insomnia, which will play a positive role in helping patients reduce their use of sleeping medications.

Association of Acupuncture and Auricular Acupressure With the Improvement of Sleep Disturbances in Cancer Survivors: A Systematic Review and Meta-Analysis

Background

Studies on the efficacy of acupuncture and auricular acupressure on sleep disturbances in cancer patients have been growing, but there is no specific and comprehensive systematic review and meta-analysis. This review aims to evaluate the efficacy and safety of acupuncture and auricular acupressure on sleep disturbances in cancer survivors based on existing randomized clinical trials (RCTs).

Methods

Four English-language and four Chinese-language biomedical databases were searched for RCTs published from database inception to July 30, 2021. RCTs comparing acupuncture and auricular acupressure with sham control, drug therapy, behavior therapy, or usual care for managing cancer were included. The quality of RCTs was appraised with the Cochrane Collaboration risk of bias (ROB) tool. Mean differences (MDs) and 95% confidence intervals (CIs) were calculated for the effect sizes.

Results

Thirteen RCTs with 961 patients were included. The risk of performance bias or reporting bias for most of the included trials was high or unclear. Evidence was not found for short-term effects on sleep scales compared to sham control (MD, 1.98; 95% CI, 0.33-3.64; p = 0.02; I² = 36%), wait list control (MD, 0.40; 95% CI, -0.87-1.68; p = 0.54; I² = 49%), drug therapy (MD, 1.18; 95% CI, -3.09-5.46; p = 0.59; I² = 98%). For long-term effect, two sham-controlled RCTs showed no significance of acupuncture on insomnia scale scores (MD, 1.71; 95% CI, -2.38-5.81; p = 0.41; I² = 89%). Subgroup analyses suggested no evidence that auricular acupressure (MD, 3.14; 95% CI=1.52, 4.76; p = 0.0001; I² = 0%) or acupuncture (MD, 0.54; 95% CI=-1.27, 2.34; p = 0.56; I² = 0%) was associated with the reduction in insomnia scale scores.

Conclusions

This systematic review and meta-analysis found no evidence about acupuncture or auricular acupressure in the improvement of sleep disturbances in cancer survivors in terms of short- or long-term effect. Adverse events were minor. The finding was inconsistent with previous research and suggested that more well-designed and large-scale randomized controlled trials are needed to identify the efficacy of acupuncture and auricular acupressure for sleep disturbances in cancer survivors.

Multi-stakeholder perspectives on managing insomnia in cancer survivors: recommendations to reduce barriers and translate patient-centered research into practice

PURPOSE

Insomnia is a debilitating symptom experienced by nearly 60% of cancer survivors. Building on our prior research showing the clinical benefit of cognitive behavioral therapy for insomnia (CBT-I) and acupuncture, we organized a workshop of patient advocates and clinician stakeholders to understand the barriers and develop recommendations for the dissemination and implementation of these interventions.

METHODS

Participants completed a pre-workshop survey assessing their experiences with insomnia and barriers to insomnia treatment and participated in a workshop facilitated by professionals and patient experts. Responses from the survey were tabulated and the discussions from the workshop were content-analyzed to extract relevant factors that may influence dissemination and implementation.

RESULTS

Multidisciplinary and stakeholder workshop participants (N = 51) identified barriers and proposed solutions and future recommendations for dissemination and implementation of evidence-based interventions to improve sleep health in cancer survivors. Barriers were identified in four categories: patient (e.g., knowledge, time, cost), clinician (e.g., education, time, capacity), institutional (e.g., space, insurance reimbursement, referrals), and societal (e.g., lack of prioritization for sleep issues). Based on these categories, we made six recommendations for dissemination and implementation of research findings to improve clinical sleep management in oncology.

CONCLUSION

Dissemination and implementation efforts are necessary to translate research into clinical practice to improve patient care.

IMPLICATIONS FOR CANCER SURVIVORS

Sleep needs to be prioritized in cancer care, but patient, provider, and institutional/societal barriers remain. Dedicated effort and resources at each of these levels are needed to help millions of people affected by cancer manage their insomnia and improve their quality of life.
