Brief Summary

The purpose of this study is to assess the impact of using autonomous artificial intelligence (AI) system for identification of diabetic retinopathy (DR) and diabetic macular edema on productivity of retina specialists in Bangladesh. Globally, the number of people with diabetes mellitus is increasing. Diabetic retinopathy is a chronic, progressive complication of diabetes mellitus that affects the microvasculature of the retina, which if left untreated can potentially result in vision loss. Early detection and treatment of diabetic retinopathy can prevent potential blindness. Study Aim: To assess the impact of using autonomous artificial intelligence (AI) system for detection of diabetic retinopathy (DR) and diabetic macular edema on physician productivity in Bangladesh. Main study question: Will ophthalmologists with clinic days randomized to use autonomous AI DR detection for all persons with diabetes (diagnosed or un-diagnosed) visiting their clinic system have a greater number of examined patients with diabetes (by either AI or clinical exam), and a greater complexity of examined patients on a recognized grading scale, per physician working hour than those randomized not to have autonomous AI screening for their diabetes population? The investigators anticipate that this study will demonstrate an increase in physician productivity, supporting efficiency for both physicians and patients, while also addressing increased access for DR screening; ultimately, preventing vision loss amongst diabetic patients. The study has the potential to contribute to the evidence base on the benefits of AI for physicians and patients. Additionally, the study has the potential to demonstrate the benefits (and/or challenges) of implementing AI in resource-constrained settings, such as Bangladesh.

Outcome Measures

Primary Outcomes (2)

  • Number of Completed Care Encounters Among Clinic Patients With Diabetes Per Retina Specialist Clinic Hour

    Number of completed care encounters among clinic patients with diabetes per retina specialist clinic hour. Numerator is the number of care encounters among patients with diabetes (including persons evaluated by autonomous AI on Intervention Days who are determined not to need to see the retina specialist). The denominator is retina specialist clinic time in hours.

    105 randomized clinic days

  • Number of Completed Care Encounters Among All Clinic Patients (With and Without Diabetes) Per Retina Specialist Clinic Hour

    Number of completed care encounters among all clinic patients (with and without diabetes) per retina specialist clinic hour. Numerator is the number of completed care encounters (including persons evaluated by autonomous AI on Intervention Days who are determined not to need to see the retina specialist). The denominator is retina specialist clinic working time in hours.

    105 randomized clinic days

Secondary Outcomes (2)

  • Specialist Productivity Adjusted for Patient Complexity for Patients With Diabetes

    105 randomized clinic days

  • Number of Participants Who Were Very Satisfied or Satisfied With Autonomous AI

    105 randomized clinic days

Study Arms (2)

Intervention Group

EXPERIMENTAL

Autonomous AI results are used to evaluate if the participant needs to see the retina specialist (positive result) or not (negative result).

Diagnostic Test: Results utilized from autonomous AI diagnostic system for diabetic retinopathy and/or diabetic macular edema

Control Group

NO INTERVENTION

All participants see the retina specialist irrespective of the results of their autonomous AI evaluation.

Interventions

If patients receive a negative result they do not see the retina specialist

Intervention Group

Masking Details
The retina specialists are masked both to patient group assignment (that is, whether autonomous AI results were used or not on the particular clinic day) and also masked to the results of the autonomous AI on Intervention days. Patients are also masked to group assignment and autonomous AI screening results.
