P17.25.A SHARED DECISION MAKING INTERVENTIONS IN NEURO-ONCOLOGY

Abstract BACKGROUND Shared decision-making (SDM) has been shown to be beneficial to patients and improve health outcomes. While more research is being conducted on the topic of shared decision-making, the incorporation of aids or interventions to facilitate or improve SDM in neurooncology has not been widely studied. This study aimed to systematically review the types and impact of SDM aids and interventions used in neuro-oncology. MATERIAL AND METHODS Systematic searches were conducted in Medline, Embase, Global Health, Cinahl, Web of Science, and Scopus from inception to May 2024. Full-text, peer-reviewed articles were evaluated based on inclusion criteria. Data extracted from articles included author, year, location, type of intervention (or decision aid), and variable outcomes. RESULTS The searches resulted in 4673 original articles. Three studies with a total of 122 patients with diagnoses of high-grade glioma (HGG), low-grade glioma (LGG), and metastases met the inclusion criteria. Types of SDM aids and interventions included SDM training for health care workers, decision grids, three-dimensional (3D) printed models of brain tumors, and an online tool providing information on disease progression. Overall impact of SDM interventions and aids resulted in improvement in patients’ understanding of their medical condition, treatment options, and satisfaction with the SDM process. CONCLUSION Few types of interventions and aids were shown to have a positive impact on SDM for neuro-oncology patients. However, this systematic review highlights the current lack of SDM interventions and aids used in neuro-oncology literature. Therefore, future research on SDM interventions and aids in neuro-oncology is warranted.
