Learning to become a primary care professional: insights from threshold concept theory.

Threshold Concepts are fundamental ideas within a discipline which are transformative, integrative, irreversible and usually troublesome. This article describes the threshold concept framework and discusses how it can offer new insights into how we focus teaching and facilitate learning around these concepts, such as uncertainty. Relevant research from a range of health disciplines are explored to consider which concepts may be critical to thinking and practising effectively in primary care. In addition, it is proposed that threshold concepts may have relevance to the GP recruitment crisis.
