Objetivo principal: Determinar la tasa de transmisión de brucelosis entre los contactos domiciliarios de casos índices con brucelosis aguda, mediante el tamizaje activo. Objetivos secundarios: Determinar los factores asociados para el desarrollo de brucelosis en los contactos domiciliarios, y la tasa de casos con brucelosis asintomática. Método: se realizará un estudio de cohortes retrospectivo con los contactos domiciliarios de los casos índices con brucelosis diagnosticados entre agosto 2007 y agosto 2010. La información será recolectada en una ficha clínica del estudio. El análisis multivariado será realizado para la identificará factores asociados al desarrollo de brucelosis entre los contactos domiciliarios de los casos índices.

Objective: To determine whether an educational intervention strategy would improve the frequency of medical prescriptions for adequate thromboprophylaxis in a medicine service. Methods: Quasi-experimental study, in which in the pre-intervention phase the frequencies of indication of appropriate thromboprophylaxis by physicians from the medicine service were obtained. An 8-week educational intervention was carried out with this same group of doctors. In the post-intervention phase, the frequency of adequate thromboprophylaxis was measured at 2 and 4 months after the intervention. Results: The educational intervention was implemented in 112 resident physicians in medicine specialties. All prescriptions were made by the first-year resident physicians and endorsed by their supervising physician. Prior to the intervention, 47 (44.35%) adequate prescriptions were obtained, 13 (12.26%) suboptim...
