<i>If instruments could talk:</i> Trace-based communication and its implications in the curriculum for trainee-supervisor interactions

Contrary to common belief, effective communication is not only achieved <i>via</i> verbal exchanges of information. It requires a thoughtful combination of verbal and non-verbal cues since, in some circumstances, verbal communication in healthcare may be impossible, unfavourable or ineffective. The semiotics literature suggests that effective non-verbal communication goes beyond body language and gestures. It also includes the use of objects (i.e. traces) to transmit a message. We call this trace-based communication (TBC). In this perspective paper, we offer some reflections from our experience researching and using trace-based communication for training purposes. Our intention was to bring further awareness to the opportunities that trace-based communication might enable, including opportunities to enhance trainee-supervisor interactions, and consequently inform curriculum design.
