Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a clinical trial to evaluate the effects of universal screening for diabetic retinopathy (DR) and diabetic macular edema (DME) using artificial intelligence (AI) in the interpretation of fundus photographs obtained by trained nursing assistant using a portable fundus camera in a primary care setting, compared with images obtained by the same method, but interpreted by ophthalmologists.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The AID-DR trial is designed as a randomized, controlled, double-blinded, non-inferiority trial with two parallel groups and a primary endpoint of adequate referrals to specialized care. Randomization will be performed in a 1:1 ratio using variable block sizes.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

RDIA group

The proposed intervention is the provision of universal screening for DR with retinography performed on a mobile fundus camera under mydriasis supported by a computer program in adults with diabetes mellitus; based on the diagnosis made by the computer program, patients will be classified as having referable DR or not, and referral to a specialist will be based on this classification.

Group Type EXPERIMENTAL

Mobile retinography interpreted by artificial intelligence

Intervention Type DIAGNOSTIC_TEST

All participants will undergo mobile retinal photography in primary care by a trained nursing assistant. If randomized to RDIA group, their photos will be analyzed by artificial intelligence.

RDOF group

The proposed control is the provision of universal screening for DR in adults with diabetes mellitus with retinography performed on a mobile fundus camera under mydriasis and with obtained images being interpreted remotely by ophthalmologists; based on the diagnosis made by the ophthalmologist, patients will be classified as having referable DR or not, and referral to a specialist will be based on this classification.

Group Type ACTIVE_COMPARATOR

Mobile retinography interpreted by ophthalmologists

Intervention Type DIAGNOSTIC_TEST

All participants will undergo mobile retinal photography in primary care by a trained nursing assistant. If randomized to RDOF group, their photos will be interpreted remotely by ophthalmologists.
