Continuity of supervision: Does it mean what we think it means?

Context Continuity of supervision (CoS) is generally accepted as an important element of competency‐based medical education (CBME). However, collecting and interpreting evidence for its effectiveness are a challenge because we lack a shared understanding of CoS. Translating the available evidence about CoS into practice is an even greater challenge because the evidence largely exists in the undergraduate medical education (UME) literature, whereas literature about CBME is mostly situated in postgraduate medical education (PGME). Proposal We explore the potential dangers of basing assumptions of the importance of CoS in CBME on evidence from the UME level where CBME is yet to be widely implemented. First, we discuss current understandings of what is meant by CoS and examine some of its evidence and where such evidence comes from. Next, we consider relevant theories related to CoS in the context of CBME and review how it is conceptualised in different educational models. We then discuss some contextual and pedagogical differences between UME and PGME when CoS is considered. Finally, we propose a shared understanding of CoS and outline implications and next steps to determine if the benefits of CoS seen at the UME level will also manifest with PGME learners. Conclusions We have the opportunity to undertake research to close our gap in knowledge about CoS at the PGME level using data emerging from our experiences with CBME. Selecting specific dimensions of CoS will allow research that is necessary to determine that what works at the UME level will also work at the PGME level as we continue to march towards CBME.
