Effect of Nudges to Clinicians, Patients, or Both to Increase Statin Prescribing: A Cluster Randomized Clinical Trial

Nudges — which present information or set choices to achieve desired behavior — increased guideline based statin prescribing over usual care. Clinician nudges alone had a small effect, patient nudges alone had no effect, and combined clinician and patient nudges had the greatest effect, increasing prescribing by 7.2 percentage points. The interventions employed a common electronic health record (EHR) system, making them generalizable and scalable.
