Video Intervention to Improve Understanding of Diabetic Retinopathy at Zuckerberg San Francisco General Hospital and Trauma Center

April 6, 2026 updated by: University of California, San Francisco

Addressing Low Patient Follow-up Rates Among Patients With Diabetes in the Eye Clinic at Zuckerberg San Francisco General Hospital and Trauma Center

The study will evaluate whether videos can improve understanding of diabetic eye disease, and follow-up rates in the eye clinic.

Detailed Description

Health literacy is a prevalent issue at Zuckerberg San Francisco General Hospital, particularly at the eye clinic where understanding of diagnoses and treatment plans largely affect vision outcomes. This study will determine whether video-based explanations, created in both English and Spanish, of diabetic retinopathy can improve knowledge concordance and follow up rates among patients in the eye clinic. Knowledge concordance and patient satisfaction will be assessed through digital surveys in Qualtrics.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Knowledge Concordance Assessed through Validated Questionarres
Time Frame: 12 months
Validated questionnaires in Qualtrics consisting of multiple choice questions and scales from 0 through 10 will be used to assess knowledge concordance before and after the patient's appointment. The change in concordance will be determined for each patient.
12 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Follow Up Adherence, Assessed through Electronic Record Review
Time Frame: 12 months
The number of scheduled follow-up appointments versus the number of attended follow-up appointments will be compared for each patient through electronic record review.
12 months
Diabetic Retinopathy Progression, Assessed through Electronic Health Record Review
Time Frame: 12 months
Electronic health records and ocular imaging will be reviewed to determine whether patients' diabetic retinopathy has progressed or improved. The numbers of patients with mild, moderate, severe, and proliferative diabetic retinopathy will be compared between groups at the end of the study period.
12 months
