Importance: In the surgical community, there is concern that general surgery residents are choosing subspecialty training in large numbers because of a crisis in confidence at the end of training. Survey studies are used as evidence to support modifications in the training paradigm.Objectives: Confidence is an essential quality of surgeons, and recent studies have attempted to quantify and measure it in graduating general surgery residents. This study was undertaken to systematically review the quality of evidence provided, and to critically analyze the language used to describe the findings using quantitative methods..Evidence Review: A systematic review of the PubMed indexed literature on general surgery resident confidence was performed. A summative table of each study's hypothesis, definition of confidence, quality using MERSQI, influence using Web of Science citations, results and conclusions was created, and qualitative coding was applied to identify emerging themes. Conclusions and Relevance: Confidence is difficult to define and measure. Despite limitations, survey studies are used to shape discourse and influence policies. Social and cultural factors influence selfefficacy, and focusing on operative volume and autonomy alone may not address all of the reasons that some residents express concerns about readiness to practice.
