Benefits of Ophdiat, a telemedical network to screen for diabetic retinopathy: a retrospective study in five reference hospital centres.

AIM One objective of Ophdiat, a telemedical network using digital non-mydriatic cameras in Ile-de-France, is to develop a comprehensive screening programme that provides access to annual fundus examinations to all diabetic patients. The aim of this study was to evaluate the benefits of this programme in a hospital setting. METHODS A retrospective analysis of 500 case reports of diabetic patients hospitalized before and after Ophdiat setup was performed in five reference hospital centres. At each centre, 100 case reports (50 before, 50 after) of patients aged greater than 18 years, hospitalized for their annual check-up, with no known diabetic retinopathy (DR) before hospitalization and with the last fundus examination performed greater than 11 months previously, were randomly selected. The primary endpoint was the proportion of patients whose fundus examinations were performed during hospitalization; secondary endpoints were the number of cases of DR found and the time taken by ophthalmologists to make the diagnosis. RESULTS The mean proportion of patients with fundus examinations was 50.4% and 72.4% before and after, respectively, Ophdiat (P<0.01). The prevalence of DR was 11.1% before and 12.7% after (not significant). The mean time taken by an ophthalmologist per diagnosis of DR was 0.90 half-day before and 0.32 half-day after Ophdiat. CONCLUSION This evaluation shows that Ophdiat, combined with the availability of modern and effective devices, has improved DR screening in diabetology departments in hospitals. Additional human resources would certainly ensure more effective use of the system.
