Background As residency programmes transition to competency‐based medical education, there has been substantial inquiry into understanding how ad hoc entrustment decisions are made by attending supervisors in the clinical context. However, although attendings are ultimately responsible for the decisions and actions of resident trainees, senior residents are often the ones directly supervising junior residents enrolled in competency‐based training programmes. This clinical dynamic has been largely overlooked in the ad hoc entrustment literature. The purpose of this study was to explore the considerations senior residents entertain when making ad hoc entrustment decisions for their junior resident colleagues. Methods In semi‐structured interviews, 11 senior resident supervisors (third, fourth and fifth year) in obstetrics and gynaecology described how they entrust junior residents with clinical activities in the moment. Following constructivist grounded theory methodology, data were iteratively collected and coded with constant comparison until theoretical sufficiency was determined. Results Senior residents described many similar considerations as attendings regarding ad hoc entrustment of junior residents, including patient safety, desire to optimise the learning environment, junior resident qualities (such as discernment and communication skills), learner handover from colleagues, and situational factors. Uniquely, senior residents discussed how their role as a middle manager and their desire to protect the junior resident (from burnout, becoming a second victim and from attendings) impacts their decisions. Conclusions Although senior residents make ad hoc entrustment decisions with some similar considerations to attendings, they also seem to think about additional factors. It may be that these different considerations need to be accommodated in documentation of ad hoc entrustment decisions if these documents are to be used for high‐stakes summative entrustment decisions made by competency committees.
