A critical review of clinician-directed nudges.

As nudges-subtle changes to the way options are presented to guide choice-have gained popularity across policy domains in the past 15 years, healthcare systems and researchers have eagerly deployed these light-touch interventions to improve clinical decision-making. However, recent research has identified the limitations of nudges. Although nudges may modestly improve clinical decisions in some contexts, these interventions (particularly nudges implemented as electronic health record alerts) can also backfire and have unintended consequences. Further, emerging research on crowd-out effects suggests that healthcare nudges may direct attention and resources toward the clinical encounter and away from the main structural drivers of poor health outcomes. It is time to move beyond nudges and toward the development of multi-level, structurally focused interventions.
