An App-based Instructional Platform to Improve Eye Drop Recall

The goal of this interventional study is to assess whether an in-office, language-concordant instructional app improves drop regimen recall in a population of glaucoma patients who are on multi-drop regimens.

Participants will be divided into two groups -- those who use the app and those who do not. The app will have narrated information regarding the drop regimen, a quiz to test understanding of the regimen, and will enable a graphical printout of the eye drops and schedule.

At one month, both groups will be assessed on their eye drop regimen recall.

Specific Aim: To investigate whether a language-concordant instructional application improves drop regimen recall in population of glaucoma patients at a 1-month follow-up period.

App features

1. Pictorial representation of drops (color-coded) and schedule.
2. Quiz to assess understanding of the regimen.
3. Narrated instructions (language-concordant) on how and when (frequency and eye laterality) to take each drop.
4. Graphical print-out of the regimen.

Study design

1. Study design: Randomized study, two groups: (1) patients that use the app, and (2) patients that do not use the app.

2. Study population:

   Inclusion criteria: patients with primary open-angle glaucoma on at least 2 eye drops

   Exclusion criteria: patients taking additional prescribed eye drops for other eye conditions; patients diagnosed within the last 3 months; patients unable to self-administer eye drops

3. Intervention: Use of an in-office app that has both graphical and verbal (language-concordant) instruction for how to use drops.
4. Main outcome measure: Ability to correctly identify drops/regimen
