Did We Get It All? An Exploratory Study of Goals, Information Needs, and System Requirements for Cancer Surgeons Assessing Breast Tumor Margins
SessionPoster Session 2
DescriptionSurgery to excise cancerous breast tumors is imperfect, and it is difficult to know that all cancerous tissue was removed successfully. A positive margin, where cancer is on the surface of the excised tissue, indicates that cancer may remain in the body and often requires a second operation. This study is part of a larger project aiming to reduce re-excision rates by developing a device to assess cancer margins intraoperatively, following tumor resection. The purpose of this study is to explore the goals, decisions, information needs, and system requirements of the surgeon during breast cancer surgery. We conducted semi-structured interviews using the Systems Engineering Initiative for Patient Safety (SEIPS) model with 11 breast surgeons to understand how they are currently performing resections and performed a qualitative thematic analysis. We found three main goals with a total of 13 sub-goals; the three main goals are: treating cancer, meeting patient needs, and meeting institutional needs. Surgeons made multiple decisions for each sub goal, and surgeons required multiple information elements to make these decisions. Our results will inform the design of a technology to support margin assessment, specifically the information displays, with sociotechnical systems-based analysis to ensure the technology fits in clinician workflow.
