Abstract

We study whether vouchers with and without value information encourage completion of already free follow-up appointments in a low-income minority population in Baltimore City referred for possible eye disease. Between May 2017 and September 2018, 821 individuals referred for free follow-up from 114 screening events received 1) standard referral, 2) a voucher redeemable for free follow-up and prescription glasses, or 3) a voucher including a statement of monetary value ($250). All referred individuals received patient education, counseling, and appointment reminders. We find that vouchers without and with value information increase follow-up appointments by 12.5 and 20.3 percentage points, respectively, corresponding to a 36%-58% increase compared to the standard referral with no voucher. We conclude that reframing free targeted health service offers by providing vouchers with value information is a promising, low-cost tool to increase uptake.
