ABSTRACT

OBJETIVOS: Conocer la cobertura de un programa de cribado de retinopatía diabética en atención primaria y la concordancia entre médicos de familia (MF) y oftalmólogos. MATERIAL Y MÉTODOS: Estudio observacional transversal. Revisión de retinografías midriáticas de pacientes con diabetes mellitus tipo 2 (2007-2008) solicitadas por MF de tres centros de salud urbanos en Jaén,España. RESULTADOS: En total 296 retinografías (2007) y 380 (2008) (cobertura=26 por ciento±2.4).Retinografías patológicas: 181 MF (27 por ciento±1.3) y 59 (9 por ciento±0.3) oftalmólogos. Concordancia global moderada (kappa=0.408±0.039), que mejora del primer al segundo año (0.34 y 0.45; p<0.001, prueba χ2). La interpretación de los MF tiene sensibilidad, 97 por ciento, especificidad, 80 por ciento, VPP, 33 por ciento, VPN, 100 por ciento, cociente de probabilidad positivo, 4.88 y negativo, 0.04. Hay variabilidad en cobertura y concordancia entre centros de salud. CONCLUSIONES: La retinografía midriática realizada e interpretada por MF es útil como cribado de retinopatía en diabéticos. En el segundo año se mejora cobertura, valores predictivos y cocientes de probabilidad, aunque se debe homogeneizar la interpretación.


OBJECTIVE: To identify the coverage of a diabetic retinopathy screening program in primary health care and to assess agreement between ophthalmologists and family physicians (FP) regarding retinography evaluations of diabetic patients. MATERIALS AND METHODS: Cross-sectional observational study,with a review of diabetic patients' mydriatic retinographies (2007-2008) from three urban primary health centers (PHC)(Jaén-Spain). RESULTS: A total of 296 retinographies in 2007 and 380 in 2008 (coverage=26 percent±2,4) were reviewed. Pathological retinographies were identified by 181 FPs (27 percent±1,3) and 59 (9 percent±0,3) ophthalmologists.Total agreement was moderate (kappa=0,408±0,039).Agreement was better in the latter year (0,45 vs 0,34; p<0,001 test χ2). FP evaluations showed 97 percent sensitivity,80 percent specificity,33 percent positive predictive value, 100 percent negative predictive value, 4, 88 positive likelihood ratio and 0,04 negative likelihood ratio. We find variability in coverage and agreement between PHC. CONCLUSIONS: Mydriatic retinographies performed and evaluated by FPs are useful to retinopathy screening of diabetic patients. Coverage, predictive values and likelihood ratio were better in the latter year, although the interpretation should be homogenized.
