Armes et Interventions
Groupe de participants / Bras |
Intervention / Traitement |
|---|---|
|
Aucune intervention: 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).
|
|
|
Expérimental: 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." |
|
Expérimental: 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
Délai: 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.
