In their efforts to provide evidence-based care healthcare professionals prescribe, provide advice, conduct examinations, perform surgical procedures, and engage in a range of clinical behaviours. Their clinical actions are characteristically performed repeatedlysometimes multiple times per day -in the same physical locations with the same colleagues and patients, under constant time pressure and competing demands. This repetition under pressure in a stable setting provides ideal circumstances for creating contingencies between physical and social cues and clinical actions. Healthcare professional behaviour provides an ideal setting in which to advance theory, methods and interventions to better understand habit formation and habit reversal. Contemporary theoretical and methodological development in the psychology of habit has begun to be applied to understand and promote the formation, breaking, and replacement of habitual behaviour in healthcare professionals. This chapter highlights key theoretical approaches, methods, and intervention techniques that have been applied to conceptualize, measure, develop, and break habit and automaticity in healthcare professionals. These insights have the potential to synergistically contribute novel perspectives to the wider habit literature.
