Abstract
A positive margin following tumor resection (i.e., surgical removal of a cancerous tumor) indicates that cancer may remain in the body and can require a re-operation. This study is part of a larger project designing a technology to support the intraoperative evaluation of margins. This study explores the goals, decisions, information needs, and system requirements of a surgeon performing breast cancer surgery. We conducted semi-structured interviews with 11 breast surgeons to understand how they currently perform resections and then performed a qualitative thematic analysis. We identified three main goals and 13 subgoals. The three main goals are: treating cancer, meeting patient needs, and meeting institutional needs. Surgeons made multiple decisions to accomplish each sub goal and required multiple information elements to make these decisions. Our results will inform the design of the new technology and a sociotechnical systems-based analysis to ensure the technology fits in surgeon workflow.
