Abstract
Background: Breast cancer patients report high levels of psychosocial maladjustment after hospital discharge. Peer support may play an important role in improving anxiety and quality of life in breast cancer patients. This study aimed to assess the effect of peer support on quality of life and anxiety in breast cancer patients.
Method: A systematic review and meta-analysis of randomized controlled studies were conducted, using data sourced from PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, SinoMed, China Science and Technology Periodical Database, China National Knowledge Infrastructure, and Wanfang Data for randomized controlled trials (RCTs) from inception to October 15, 2021. The RCTs reporting the effect of peer support intervention on quality of life and anxiety in breast cancer patients were included. The quality of evidence was assessed using the Cochrane risk of bias tool, that is, the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Standardized mean differences (SMDs) and 95% confidence intervals (CIs) were calculated for the pooled effect size.
Results: A total of 14 studies were included in the systematic review and 11 in the meta-analysis. The pooled results revealed that peer support significantly improved quality of life (SMD = 0.69, 95% CI = 0.28-1.11) and anxiety (SMD = -0.45, 95% CI = -0.88 to -0.02) in breast cancer patients. The quality of evidence was low as all studies showed the risk of bias and inconsistency.
Conclusion: Peer support intervention has the potential to effectively improve psychosocial adaptations in breast cancer patients. Future studies with a robust design and larger sample size are needed to investigate the potential factors associated with the beneficial effects of peer support.
背景：乳腺癌患者出院后的社会心理适应不良程度很高。同伴支持在改善乳腺癌患者的焦虑和生活质量方面可能发挥重要作用。本研究旨在评估同伴支持对乳腺癌患者生活质量和焦虑的影响：方法：采用PubMed、Embase、Cochrane Central Register of Controlled Trials、Web of Science、SinoMed、中国科技期刊数据库、中国国家知识基础设施和万方数据中从开始到2021年10月15日的随机对照试验（RCTs）数据，对随机对照研究进行了系统综述和荟萃分析。研究纳入了报告同伴支持干预对乳腺癌患者生活质量和焦虑的影响的随机对照试验。证据质量采用科克伦偏倚风险工具，即建议评估、发展和评价分级法（GRADE）进行评估。计算了汇集效应大小的标准化平均差（SMDs）和 95% 置信区间（CIs）：共有 14 项研究被纳入系统综述，11 项研究被纳入荟萃分析。汇总结果显示，同伴支持能显著改善乳腺癌患者的生活质量（SMD = 0.69，95% CI = 0.28-1.11）和焦虑（SMD = -0.45，95% CI = -0.88-0.02）。由于所有研究都存在偏倚和不一致的风险，因此证据质量较低：结论：同伴支持干预有可能有效改善乳腺癌患者的社会心理适应能力。未来的研究需要采用可靠的设计和更大的样本量，以调查与同伴支持的有益效果相关的潜在因素。
