Management of diabetic retinopathy by general practitioners in Victoria

Purpose: To compare the self-reported management of diabetic retinopathy by general practitioners to the National Health and Medical Research Council of Australia (NHMRC) Guidelines for the Management of Diabetic Retinopathy. Methods: In 1994, a stratified (by urban/rural practice location) sample of 500 general practitioners in Victoria was surveyed in regard to their mana gement of diabetic retinopathy. Following the release of the NHMRC Guidelin es for the Management of Diabetic Retinopathy in 1997, these same general p ractitioners were sent a two-page questionnaire related to their management of diabetic retinopathy. Results: Completed questionnaires were received from 228 general practition ers (59% of original participants). Only 37% (79/216) of the general practi tioners reported that they had received a copy of the guidelines. Of the ge neral practitioners who had received the guidelines, 18% (14/79) said that they had not read them at all, while 65% (51/79) had read them partially an d 18% (14/79) had read them in their entirety. At follow up, less than half (98/214) of general practitioners reported examining 50% or more of their patients for diabetic retinopathy, compared with 104/214 at baseline. Gener al practitioners who had read the guidelines were more likely to report tha t not being sure what to do when changes were detected was a minor barrier or was not a barrier to them performing dilated ophthalmoscopy (93% vs 83%, chi (2)(1) = 3.67, P = 0.055). Nearly all of the general practitioners rep orted that they refer their patients with diabetes to an ophthalmologist or optometrist at least every 2 years as recommended. Seventy-six per cent (1 70/224) of the general practitioners felt that 70% or more of their patient s complied with their instructions to visit an ophthalmologist or optometri st. Conclusion: The NHMRC guidelines for diabetic retinopathy appear to have ha d a positive effect on some of the attitudes of general practitioners who h ave read them, but more effort is needed to disseminate the guidelines to a ll general practitioners and to increase their uptake.
