Decision aids for breast cancer screening in women approximately 50 years of age: A systematic review and meta‐analysis of randomised controlled trials

Abstract

Aims and ObjectivesReview the content, quality and effect of breast cancer screening decision aids (BCS‐DAs) in women approximately 50 years of age to provide a basis for the development of DAs.BackgroundBreast cancer screening (BCS) decisions are complex and should vary depending on a woman's risk of breast cancer and her values and preferences. Decision aids (DAs) can help support women and medical staff in shared decision‐making (SDM) when solving BCS problems.DesignSystematic review and meta‐analysis.MethodsFour databases were searched starting at the time of establishment of the database to March 2021. The PRISMA checklist was followed. The meta‐analysis was carried out using Review Manager 5.3 software. The quality of the studies was assessed using the risk of bias tool recommended by the Cochrane Handbook. The quality of the DAs was assessed using the International Standards for Decision Aid (IPDASi v4.0).ResultsThe search strategy obtained 2024 references. After abstraction and full text screening, a total of seven studies were included. This article systematically reviews the content, quality and effectiveness of DAs in seven RCTs in helping women to make BCS decisions. The DAs were mostly in paper or online form and displayed disease screening information, analysed the benefits and harms of options and clarified the value to patients. Among all the DAs, only one met the minimum quality standards of IPDASi v4.0. Comprehensive analysis shows that DAs can significantly improve knowledge and increase the proportion of women who make informed choices, but they have no effect on screening attitude, intention, decision conflict or regret.ConclusionsIn the future, nurses should be encouraged to develop DAs in accordance with strict standards and to make them applicable to young women of different backgrounds.Relevance to clinical practiceThe result may be provide a basis for the development of DAs to promote women's informed screening choices.

Effect of music therapy on anxiety and depression in breast cancer patients: systematic review and meta-analysis

“…In the past 20 years, the incidence of breast cancer in China has increased by 37.6%, with an average annual growth rate of 2.3% 2 . Breast cancer patients are the phenomenon of uncontrolled proliferation of breast epithelial cells under the action of multiple carcinogenic factors; physiologically, the early stage often manifests symptoms such as breast lumps and enlarged axillary lymph nodes, and in the late stage, due to distant metastasis of the cancer cells, multi-organ lesions may occur, and even threaten the patients' lives 3 . Patients need to endure the pain and side effects of chemotherapy during treatment, and psychologically they often show emotional instability, anxiety depression, etc., and most of them have psychological problems such as moderate and severe anxiety levels.…”

Development of support material for health professionals who are implementing Shared Decision-making in breast cancer screening: validation using the Delphi technique

“…However, SDM is not explicitly recommended for screening programmes. And the scientific community is making efforts to create patient decisions aids (PtDAs)6 7 to be integrated in the early detection programmes of autonomous communities, but, at the moment, its use is not widespread.…”
