Providing Financial Incentives to Improve Adherence to Referral Eye Care Visits (AL-SIGHT)

July 29, 2025 updated by: Cynthia Owsley, University of Alabama at Birmingham

Using Telemedicine to Prevent Blindness in an At-risk Rural Alabama Population

Glaucoma is a blinding eye disease increasingly common in older adults, particularly in African Americans, and often diagnosed late in the disease course. It is essential to develop novel health care models, utilizing telemedicine, to improve the ability to detect glaucoma at an earlier stage, and to provide a platform to manage this disease in community-based clinics so that further vision loss is prevented. Our goal is to improve the quality and accessibility of glaucoma detection and management among a vulnerable and at-risk segment of our population.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The number of primary open angle glaucoma (POAG) cases will increase by 250% by 2050, directly affecting over 7 million lives. These numbers are specifically for POAG and do not include the many who are monitored and treated for elevated intraocular pressure or for glaucoma suspect status, which along with POAG can all be considered glaucoma associated diseases (GAD). Development of high-quality, accessible, and cost-effective strategies for eye care for these individuals is of critical importance. POAG is at least 4-5 times higher in African Americans, progresses more rapidly and appears about 10 years earlier as compared to those of European descent. This research plan seeks to implement and evaluate a telemedicine-based detection and management strategy for GAD and other eye diseases in patients seen at Federally Qualified Health Centers (FQHC's) located in the rural Alabama Black Belt Region. This region is characterized by one of the highest concentrations of African Americans in the US; high poverty, unemployment, and uninsured rates; inadequate educational systems, transportation and community resources; few optometrists who largely practice in retail settings; and no ophthalmologists specializing in glaucoma. The investigators have developed and tested a novel multimodal telemedicine approach in a prior Centers for Disease Control and Prevention (CDC) funded Eye Care Quality and Accessibility Improvement in the Community (EQUALITY) study that used comprehensive remote optic nerve assessment (RONA). This proposal will employ a modification of the EQUALITY approach using portable measurement of visual function and optic nerve and retinal structure that are more applicable to rural locations with limited resources. The investigators will also identify and evaluate remediation strategies for the barriers to patient adherence with referral and follow-up appointments by comparing the effectiveness of financial incentives along with a validated patient education program versus a validated patient education program alone. Using this program within FQHC's will enable expansion nationwide into rural and urban underserved locations as these centers provide primary health care services in underserved areas and treat more than 27 million people yearly at over 12,000 sites.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: No financial incentive
This group will receive standard of care eye health education alone and no financial incentive for completing a referral visit.
Other: No Financial Incentive
Standard of care eye health education
Other Names:
  • Standard of Care
Experimental: Financial incentive
This group will receive a financial incentive once the referral visit is completed (if one was required) as well as eye health education.
Behavioral: Financial Incentive
Patients who are referred for an in-person follow-up exam will receive a financial incentive once the referral visit is completed.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants That Adhere to Referral Appointment
Time Frame: The time frame will be whether they attended the referral appointment between the screening date until 6 months after the screening date.
The percentage of patients who adhere to attending their referral appointments who received a financial incentive and eye health education will be compared with the percentage of patients who adhere to attending their referral appointments who received standard of care eye health education alone and no financial incentive for completing a referral visit.
The time frame will be whether they attended the referral appointment between the screening date until 6 months after the screening date.
