El síndrome de burnout ha mantenido su estructural conceptual “síndrome tridimensional compuesto por agotamiento emocional, despersonalización y baja realización personal”. Sin embargo, habría ido aumentando su prevalencia en distintos estratos del personal sanitario y también se ha ido ampliando hacia diversas condiciones laborales. Se presentan aquí parte de los resultados de una investigación transversal de tipo correlacional mediante encuesta, cuyos datos se obtuvieron de 100 trabajadores de una empresa de salud de la CABA. Se describe la prevalencia del Síndrome de burnout, la frecuencia de sus componentes y asociación con variables sociodemográficas, laborales y personales. Las tres características asociadas a mayores niveles al síndrome de burnout son profesión (enfermeros y médicos), género (masculino) y realización de guardias (sí) que, por presentarse asociadas, dificultan su mutuo control de no mediar una ampliación de la muestra.

However, it would have been increasing its prevalence in different strata of health personnel and has also been expanding to various working conditions We present here part of the results of a cross-sectional investigation of correlational type by means of a survey, whose data was obtained from 100 workers of a company of a health company of the CABA. The prevalence of burnout syndrome, the frequency of its components and association with sociodemographic, labor and personal variables are described. The three characteristics associated with higher levels of burnout syndrome are the profession (nurses and doctors), gender (male) and the performance of guards (yes) that, because they are associated, make it difficult for them to control each other if an expansion of the sample does not occur.
