Decision aids for female BRCA mutation carriers: a scoping review protocol

INTRODUCTION: Women who inherit a pathogenic mutation in Breast Cancer Susceptibility Genes 1 or 2 (BRCA1 or BRCA2) are at substantially higher risk of developing breast and ovarian cancer than the average woman. Several cancer risk management strategies exist to address this increased risk. Decisions about which risk management strategies to choose are complex, personal and multifactorial for these women. This scoping review will map evidence relevant to cancer risk management decision making in BRCA mutation carriers without a personal history of cancer. The objective is to identify and describe the features of patient decision aids that have been developed for BRCA mutation carriers. This information may be beneficial for designing new decision aids or adapting existing decision aids to support decision making in this population. METHODS AND ANALYSIS: This scoping review will be conducted according to the Joanna Briggs Institute’s scoping review methodological framework. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist will be used for guidance. Studies on decision aids for women with a BRCA mutation who are unaffected by breast or ovarian cancer will be considered for inclusion. Five electronic databases will be searched (MEDLINE, EMBASE, Cochrane Library, CINAHL, Web of Science) with no restrictions applied for language or publication date. Studies for inclusion will be selected independently by two review authors. Data will be extracted using a predefined data extraction form. Findings will be presented in tabular form. A narrative description of the evidence will complement the tabulated results. ETHICS AND DISSEMINATION: Ethical approval for conducting this scoping review is not required as this study will involve secondary analysis of existing literature. Findings will be published in a peer-reviewed journal and presented at relevant conferences.
