Reminders, Cost Sharing, and Healthcare Use

The investigators conduct a large-scale randomized controlled trial in Finland by sending three types of information letters to households to examine whether the reminder letters affect healthcare use. All letters remind of the importance of seeking care to treat potential health problems. This study has two primary objectives are: to evaluate the effects of an information nudge reminding on the importance of diagnosing and treating health problems and to evaluate the effects of additionally providing information on the fact that primary care nurse visits have become exempt from copayments. Main outcomes include the number of primary care nurse visits and general practitioner (GP) visits in a six-month follow-up.
