Validez y concordancia de la historia clínica electrónica de atención primaria (AP-Madrid) en la vigilancia epidemiológica de la diabetes mellitus. Estudio PREDIMERC / Validity and concordance of electronic health records in primary care (AP-Madrid) for surveillance of diabetes mellitus. PREDIMERC study

Objetivo. Estudiar la validez y la concordancia de los datos de diabetes en la historia clínica electrónica de atención primaria (AP-Madrid) comparándola con el estudio PREDIMERC. Métodos. En una muestra poblacional de 2268 individuos se calcularon la sensibilidad, la especificidad, el valor predictivo positivo, el valor predictivo negativo y el índice kappa de los casos de diabetes registrados en la historia clínica AP-Madrid, comparándolos con el estudio PREDIMERC (como referencia). Se estimó la prevalencia de diabetes según cada fuente de información. Resultados. La sensibilidad para la diabetes registrada en AP-Madrid fue del 74%, la especificidad del 98,8%, el valor predictivo positivo del 87,9%, el valor predictivo negativo del 97,3% y el índice kappa de 0,78. La prevalencia de diabetes registrada fue del 6,7%, frente al 8,1% de PREDIMERC, siendo la diabetes conocida del 6,3%. Conclusiones. La AP-Madrid es un sistema de información válido para realizar estudios de vigilancia epidemiológica de diabetes en la Comunidad de Madrid (AU)

Objective. To assess the validity and concordance of diabetes data in the electronic health records of primary care (Madrid-PC) by comparing with those from the PREDIMERC study. Methods. The sensitivity, specificity, positive predictive value, negative predictive value and kappa index of diabetes cases recorded in the health records of Madrid-PC were calculated by using data from PREDIMERC as the gold standard. The prevalence of diabetes was also determined according to each data source. Results. The sensitivity of diabetes recorded in Madrid-PC was 74%, the specificity was 98.8%, the positive predictive value was 87.9%, the negative predictive value was 97.3%, and the kappa index was 0.78. The prevalence of diabetes recorded in Madrid-PC was 6.7% versus 8.1% by PREDIMERC, where known diabetes was 6.3%. Conclusions. The electronic health records of primary care are a valid source for epidemiological surveillance of diabetes in Madrid (AU)

Prevalencia de diabetes mellitus y factores de riesgo cardiovascular en la población adulta de la Comunidad de Madrid: estudio PREDIMERC / Prevalence of diabetes mellitus and cardiovascular risk factors in the adult population of the autonomous region of Madrid (Spain): the PREDIMERC study

ObjetivoDeterminar la prevalencia de diabetes y los principales factores de riesgo cardiovascular en la población adulta de la Comunidad de Madrid.Material y métodoEstudio transversal de base poblacional en el año 2007. Se seleccionó una muestra aleatoria representativa de la población de 30–74 años, con un tamaño muestral fijo para cada estrato de edad, ponderando los resultados según la estructura por edad de la Comunidad de Madrid. Se realizó una encuesta telefónica. Posteriormente, en el centro de salud se efectuó la exploración física y la extracción de sangre en ayunas para determinar la glucemia, el colesterol y las fracciones lipídicas.ResultadosSe incluyeron 2.268 personas con una edad media de 48,3 años; el 52% eran mujeres. La tasa de respuesta fue del 56,4%. El 8,1% (intervalo de confianza del 95% [IC95%]: 7,0–8,9) de la población presenta diabetes y el 5,9% (IC95%: 4,8–6,1) una glucemia basal alterada. El 29,3% (IC95%: 27,3–31,5) tiene hipertensión arterial y el 23,3% (IC 95%: 21,4–25,2) hipercolesterolemia. El 22,8% (IC95%: 20,8–25,0) presenta sobrepeso de grado II, el 21,7% (IC95%: 19,8–23,6) obesidad y el 23,9% (IC95%: 21,8–26,1) obesidad abdominal. El 85,5% (IC95%: 83,1–87,1) eran sedentarios en tiempo libre y el 28,4% (IC95%: 26,3–30,3) fumadores.ConclusionesLa prevalencia de diabetes mellitus en la Comunidad de Madrid se sitúa en una posición intermedia con respecto a otras comunidades autónomas. Los principales factores de riesgo cardiovascular tienen una elevada prevalencia. El sobrepeso de grado II y la obesidad, que afectan a 4,5 de cada 10 adultos, representan una prioridad de intervención en la prevención de la diabetes y la enfermedad cardiovascular(AU)

ObjectiveTo describe the prevalence of diabetes and major cardiovascular risk factors in the adult population of the autonomous region of Madrid (Spain).Material and methodA population-based cross-sectional study was carried out in 2007. A random sample of the population aged 30–74 years old was selected. A fixed sample size per age stratum was assigned, weighted by the real age-specific distribution of the population of the autonomous region of Madrid. An epidemiological survey was conducted by telephone. Subsequently, physical examination was performed and a fasting blood sample was taken in the health center for glucose, cholesterol and lipid fraction determinations.ResultsWe included 2268 people with a mean age of 48.3 years old (52% women). The response rate was 56.4%. Diabetes was found in 8.1% (95%CI: 7.0–8.9) of the adult population and impaired fasting glucose was found in 5.9% (95%CI: 4.8–6.1). The prevalence of risk factors was as follows: hypertension in 29.3% (95%CI: 27.3–31.5), hypercholesterolemia in 23.3% (95%CI: 21.8–26.1), overweight grade II in 22.8% (20.8–25.0), obesity in 21.7% (95%CI: 19.8–23.6), and central obesity in 23.9% (95%CI: 21.8–26.1). A total of 85.5% (95%CI: 83.1–87.1) were sedentary in their leisure time and 28.4% (95%CI: 26.3–30.3) were smokers.ConclusionsThe prevalence of diabetes in the autonomous region of Madrid is intermediate in relation to other regions of Spain. Cardiovascular risk factors are highly prevalent, and are higher in men than in women. Overweight and obesity, affecting 4.5 out of every 10 adults, should be considered a priority for health interventions in cardiovascular disease prevention(AU)
