Currently, only 44 percent of adults in the United States receive an annual flu vaccination. But, a new study suggests that a simple behavioral economics technique may be able to help. In the study, researchers programmed electronic health records (EHR) to alert care providers when a patient was eligible, and prompt them to choose to ‘accept’ or ‘decline’ a flu vaccination order. Results showed a 37 percent relative increase in vaccinations from the prior year.
