Vouchers to Increase Uptake of Already Free Eye Care
11 de junio de 2020 actualizado por: Johns Hopkins University
Providing Vouchers Redeemable for Already Free Eye Exams To Increase Uptake Among a Low-Income Minority Population: A Randomized Trial
This study was intended to test if reframing an offer for a free follow-up eye examination could increase uptake within ongoing community-based screening program for low-income and minority populations in Baltimore City.
This study evaluated the effect of offering participants a physical voucher they were told was redeemable for free follow-up, relative to simply telling participants that the follow-up appointment would be free of charge.
The investigators assessed two forms of vouchers, one with estimated value information, and one without.
The underlying hypothesis was that reframing these already free offers would increase uptake by increasing perceived offer value and increasing a sense of regret from not taking advantage of a "good deal."

Sin intervención: No Voucher
Individuals being referred from screening events randomized to "no intervention" received the standard approach to offering free follow-up examinations (patient education, standard counseling, appointment information packet, reminder phone calls).
|
|
|
Experimental: Voucher Without Value Information
In addition to receiving the standard approach above, individuals being referred from screening events randomized to "Voucher Without Value Information" received a personal voucher.
|
Patients being referred for follow-up received standard materials, counseling, and reminders as in the 'no information' group and were provided with a physical voucher they were told is redeemable for free follow-up appointment at Johns Hopkins Hospital. The voucher included the patient's name, the screener's name, and an expiration date 90 days from the date of screening. These participants were told: "I am going to give you this voucher for a completely free appointment and a free pair of glasses if you need them. So, with this voucher, both the exam and the glasses will be completely free." |
|
Experimental: Voucher With Value Information
In addition to receiving the standard approach above, individuals being referred from screening events randomized to "Voucher With Value Information" received a personal voucher, which differed from the voucher in the second arm since it included a statement of value.
|
Patients being referred for follow-up received standard materials, counseling, and reminders as in the 'no information' group and were provided with a physical voucher they were told is redeemable for free follow-up appointment at Johns Hopkins Hospital, which would normally cost $250. The voucher included the patient's name, the screener's name, an expiration date 90 days from the date of screening, and a statement about the $250 voucher value. These participants were told: "I am going to give you this voucher for a completely free appointment and a free pair of glasses if you need them. These services normally cost about $250, but with this voucher, both the exam and the glasses will be completely free." |

Uptake of follow-up appointment
Periodo de tiempo: Within 90 days of the date of screening
|
The primary endpoint was attending a follow-up appointment, either on the initially scheduled or on a rescheduled date within 90 days of the date of screening.
Individuals who did not meet this endpoint either stated that they were not interested in follow-up at the screening event itself, cancelled or did not show for their appointments on 3 occasions, stated that they were not interested in follow-up when study staff attempted to reschedule, or did not show for an appointment and could not be reached for rescheduling after 3 attempts.
