CONCORDANCIA EN EL ESTUDIO DE RETINOGRAFÍAS EN DIABÉTICOS: OFTALMÓLOGOS VS MÉDICOS DE FAMILIA AGREEMENT AMONG OPHTHALMOLOGISTS AND PRIMARY CARE PHYSICIANS IN THE EVALUATION OF RETINOGRAPHIES OF DIABETIC PATIENTS

Purpose: To assess the extent of agreement in the evaluation of non-mydriatic retinographies of diabetic patients among ophthalmologists and a group of primary care physicians with previous training. Methods: The study was divided in two phases. In the first phase, the four participants were instructed in the interpretation of retinographies. The second phase involved the evaluation of 1000 images of 200 patients, 100 without retinopathy and 100 with signs of diabetic retinopathy. The four participants had to decide if the images did or did not show evidence of diabetic retinopathy. Kappa index was used to assess the extent of agreement. A percentage disagreement of 15% with a precision of 5% (±5%) with a confidence level of 95% was considered adequate. Results: The percentage of coincident diagnoses among ophthalmologists and primary care physicians was between 89 and 97.5%. With respect to the assessment of the agreement, the kappa index
