Assessment of Annual Diabetic Eye Examination Using Telemedicine Technology Among Underserved Patients in Primary...

Digital retinal imaging with the application of telemedicine technology shows promising results for screening of diabetic retinopathy in the primary care setting without requiring an ophthalmologist on site.

We assessed whether the establishment of telemedicine technology was an effective and efficient way to increase completion of annual eye examinations among underserved, low-income (Medicaid) diabetic patients.

A cross-sectional study in a primary care setting.

Health care claims data were collected before the establishment of telemedicine technology in 2010 and after its implementation in 2012 for Medicaid patients at East Baltimore Medical Center (EBMC), an urban health center that is part of Johns Hopkins Health System.

The primary outcome measure was the compliance rate of patients with diabetic eye examinations; calculated as the number of diabetic patients with a completed telemedicine eye examination, divided by the total number of diabetic patients.

In 2010, EBMC treated 213 Medicaid diabetic patients and in 2012 treated 228 Medicaid patients. In 2010, 47.89% of patients completed their annual diabetic eye examination while in 2012 it was 78.07% (P < 0.001). After adjustment for age, gender, HgBA1C, disease severity, using resource utilization band score as a proxy, and medication possession ratio; telemedicine technology significantly increased the compliance (odds ratio: 4.98, P < 0.001).

Adherence to annual eye examinations is low in the studied Medicaid diabetic population. Telemedicine technology in a primary care setting can increase compliance with annual eye examinations.
