Barriers to annual diabetic retinopathy screening and subsequent recommended follow-up adherence among Chinese diabetics: a cross-sectional and longitudinal study.

OBJECTIVES

Adherence to routine annual eye evaluations for diabetes is frequently insufficient on a global scale. We evaluated the adherence to annual diabetic retinopathy screening (DRS) and recommended follow-up among Chinese patients with diabetes, and we also identified the associated risk variables.

DESIGN

This was a cross-sectional and longitudinal study.

SETTING

Patients with diabetes were inquired about their completion of DRS within the preceding year. All participants were required to complete the Compliance with Annual Diabetic Eye Exams Survey.

PARTICIPANTS

Participants with diabetes who initially sought eye examination from November 2021 to October 2023 at He Eye Specialist Hospital, Shenyang, China.

OUTCOME MEASURES

Logistic regression analyses defined the risk factors associated with poor compliance with the annual DRS and recommended follow-up.

RESULTS

There were 468 patients registered, with a mean age of 67.42±10.66 years. A total of 308 (65.8%) participants had DRS in the previous year. Rural residents (OR 1.704, 95% CI 1.019 to 2.850, p=0.042), vision-threatening diabetic retinopathy (VTDR) (OR 1.948, 95% CI 1.145 to 3.313, p=0.014), item 7 (over the past 4 weeks, I have felt blue, downhearted or depressed) (OR 0.624, 95% CI 0.401 to 0.971, p=0.037) and item 42 (I receive a reminder from my eye doctor's office when it is time to schedule an exam) (OR 0.618, 95% CI 0.387 to 0.989, p=0.045) were associated with non-adherence to annual DRS. The compliance with DRS improved to 80.9% in the second year after health education and reminders of follow-up. VTDR (OR 3.063, 95% CI 1.852 to 5.066, p<0.01) was found to be the risk factor for poor compliance with scheduled follow-up.

CONCLUSIONS

About one-third of diabetics did not complete annual DRS; that rate decreased to one-fifth after health education and follow-up reminders.
