Brief description Diabetes and its health complications are major public health issues presently facing Australia. Currently, around 7% of Australians have diabetes and it is estimated that 300 million people will be diabetic within 20-years. One major complication of diabetes is diabetic retinopathy, which is the most common cause of blindness in working-age adults. Although early treatment can prevent vision loss from diabetic retinopathy, often there are no visual symptoms until the condition is more advanced and less treatable. Consequently, it is vital that people with diabetes have their eyes examined regularly. We aim to investigate the use of eye services by people with diabetes. The WA Data Linkage System provides the unique opportunity to efficiently examine the benefits of specialist eye care in diabetics within WA over a 17-year period. The study period encompasses the introduction of NHMRC guidelines for diabetic retinopathy screening in 1997. This will enable us to examine the effectiveness of these guidelines in increasing ophthalmic services use by people with diabetes. Evaluating these trends will provide important data on the effectiveness of policy and NHMRC guidelines in improving diabetic eye care, which has never been comprehensively investigated. Early intervention can prevent and delay vision loss from diabetic retinopathy, substantially reducing the personal and community burden from diabetes. The identification of poorly screened groups will enable more targeted programs to improve the use of ophthalmic series, which in turn may reduce the risk of: i) eye surgery related to diabetes, ii) injury resulting from diabetes-related vision disorder or iii) blindness. The feasibility of using linked health data to evaluate eye screening in diabetics will enable future work addressing processes of care in the prevention of other diabetic complications to be undertaken quickly and cost-effectively.
