An App-based Instructional Platform to Improve Eye Drop Recall

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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 Pictorial representation of drops (color-coded) and schedule. Quiz to assess understanding of the regimen. Narrated instructions (language-concordant) on how and when (frequency and eye laterality) to take each drop. Graphical print-out of the regimen. Study design Study design: Randomized study, two groups: (1) patients that use the app, and (2) patients that do not use the app. 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 Intervention: Use of an in-office app that has both graphical and verbal (language-concordant) instruction for how to use drops. Main outcome measure: Ability to correctly identify drops/regimen

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: App arm<br>The intervention is an in-office app that contains graphical and narrated information on a patient's specific drop regimen, and includes a quiz and a graphical print-out of their drop schedule. The patient will use the app during their clinic visit. | Other: App<br>* App features (App will be used during the office visit): Pictorial representation of drops (color-coded) and schedule. Quiz to assess understanding of the regimen. Narrated instructions (language-concordant) on how and when (frequency and eye laterality) to take each drop. Graphical print-out of the regimen.<br>* Other names: App-based drop instructions;|
| No Intervention: Standard arm<br>The standard arm will be the standard of care, which involves a provider explanation of their drop regimen (using a phone interpreter if needed). | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage accuracy of drop regimen recall | This will be assessed through questions querying which drops the patients are taking, the number of times they are taking each drop, and the laterality of each drop. Each answer/drop will be individual recorded, and then total number of correct answers will be divided by the total number of questions. | 1 month follow up from time of intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall medication adherence, assessed through the modified Morisky Adherence Scale, a widely published scale for general medication adherence | An 8 question survey (7 questions are yes/no, with the final question on a Likert scale) gauging overall medication adherence. Each question will be individually assessed (not summed into a cumulative score). The higher number of yes responses corresponds to a lower adherence score. | 1 month follow up from time of intervention |
