[Tuberculosis surveillance in the Balearic Islands and characteristics of unreported cases from 2005 to 2007]. / Vigilancia de la tuberculosis en las Islas Baleares y caracterización de los casos infradeclarados entre los años 2005 y 2007.

We performed a descriptive study of tuberculosis cases detected by the Epidemiological Surveillance System in the Balearic Islands in the triennium 2005-2007. Our goal was to characterize underreported cases in sociodemographic terms and their contact with primary care. Overall, underreporting of tuberculosis was approximately 20%. Significant factors in multivariate analysis were social marginality (consisting of alcoholism, intravenous drug use or indigence) (aOR: 2.6 [1.2 to 5.3]), contact with primary care (aOR: 3.2 [1.4 to 7.1]), and extrapulmonary tuberculosis (aOR: 5.5[3.2-9.6]). We recommend strengthening notification by hospital specialists through the use of hospital electronic records. Our findings show that the information obtained from the primary care computerized history is helpful in improving the epidemiological surveillance of tuberculosis.

Estudio descriptivo de los casos de tuberculosis detectados por el Sistema de Vigilancia Epidemiológicaen Baleares, en el trienio de 2005 a 2007. El objetivo fue caracterizar los casos infradeclarados en términossociodemográficos y de su contacto con la atención primaria de salud. Globalmente, la infradeclaraciónde la tuberculosis se sitúa en torno al 20%. Las características que resultan significativas en el análisismultivariado son la marginalidad social (alcoholismo, usuarios de drogas por vía parenteral o indigencia)(odds ratio ajustada [ORa] : 2,6 [1,2-5,3]), el contacto con la atención primaria (ORa : 3,2 [1,4-7,1]) y latuberculosis extrapulmonar (ORa : 5,5 [3,2-9,6]). Se recomienda reforzar la notificación de los especialistashospitalarios mediante la adecuación informática de la historia clínica hospitalaria, y se observa quela información obtenida desde la informatización de la historia en atención primaria resulta de utilidadpara mejorar la vigilancia epidemiológica de la tuberculosis (AU)
