Original Title: Análisis coste-efectividad de la cámara de retina no-midriática en el diagnóstico de retinopatía diabética
Authors' objectives: Assess by means of a cost-effectiveness analysis the two alternatives which are used to diagnose RD: indirect ophthalmoscopy and biomicroscopy with a 78-diopter lens (the traditional method) and photograph with a 45 degree non-mydriatic retinal camera.
Authors' results and conclusions: The effectiveness of the 45º non-mydriatic retinal camera in the diagnosis of RD has a sensitivity of 91.9% and a specificity of 89.7%. Personnel costs in the traditional method represent 60% of the total cost of the diagnosis per patient; on the other hand, in the non-mydriatic retinal camera method, depreciation and maintenance costs amount to 87% of the total cost of the patient. The cost-effectiveness analysis has indicated a cost per true positive case detected of 18,883 pesetas in the traditional method, while the non-mydriatic retinal camera method is 12,642 pesetas. The use of this camera would also mean freeing 15 hours of ophthalmology resources for every 100 patients observed.
Authors' recommendations: The camera method is simple to use compared to the traditional method. It does not require the use of mydriatic drugs for the funduscopic exploration, facilitates filing for later later monitoring, has fewer requirements regarding human resources and has been seen to offer a considerably lower cost per true positive case detected. It would be advisable to consider the possiblity of using this early detection method to obtain the goal of one annual ophthamological exploration for all patients.
Authors' methods: - Bibliographical search in databases: Medline (January 1985 - September 1996), ECRI, INAHTA and the Cochrane Library. - Summary of the selected bibliography and assessment agency reports. - Drawing up of a decision tree using the Data 2.6 programme to asess the two alternatives considered in this study. - Carrying out a cost-effectiveness study and a sensitivity analysis with different hyotheses: prevalence in diabetic retinopathy, sensitivity of the non-mydriatic retinal camera, variation of the discount rate and service life of the equipment. - Dissemination of this report to health authorities, ophtalmologists, endocrinologists and economists of the publis health service.
