Description
Summary:During the influenza vaccination campaign 2011–2012 we established a self-declaration system of adverse events (AEs) in healthcare workers (HCW). The aim of this study is to describe the vaccinated population and analyse vaccination coverage and self-declared AEs after the voluntary flu vaccination in a university hospital in Barcelona. Observational study. We used the HCW immunisation record to calculate the vaccination coverage. We collected AEs using a voluntary, anonymous, self-administered survey during the 2011–2012 flu vaccination campaign. We performed a logistic regression model to determine the associated factors to declare AEs. The influenza vaccination coverage in HCW was 30.5% (n=1507/4944). We received completed surveys from 358 vaccinated HCW (23.8% of all vaccinated). We registered AEs in 186 respondents to the survey (52.0% of all respondents). Of these, 75.3% (n=140) reported local symptoms after the flu vaccination, 9.7% (n=18) reported systemic symptoms and 15.1% (n=28) both local and systemic symptoms. No serious AEs were self-reported. Female sex and aged under 35 were both factors associated with declaring AEs. Our self-reporting system did not register serious AEs in HCW, resulting in an opportunity to improve HCW trust in flu vaccination. Durante la campaña de vacunación antigripal 2011-2012 establecimos un sistema de autodeclaración de acontecimientos adversos (AA) en el personal sanitario (PS). El objetivo de este estudio es describir la población vacunada y analizar la cobertura de vacunación y los AA autodeclarados tras la vacunación voluntaria del PS frente a la gripe en un hospital universitario de tercer nivel en Barcelona. Estudio observacional. Para el cálculo de la cobertura de vacunación se utilizó el registro de vacunación de profesionales sanitarios del hospital. Los AA se recogieron mediante una encuesta voluntaria, anónima y autoadministrada durante la campaña de vacunación antigripal 2011-2012, y se analizaron mediante regresión logística. Se construyó un modelo de regresión logística para determinar los factores que predisponen a declarar AA. La campaña alcanzó una cobertura de vacunación antigripal del 30,5% (n=1.507/4.944) del PS. De los vacunados, el 23,8% (n=358) respondieron la encuesta de AA autodeclarados. El 52,0% (n=186) de los que respondieron a la encuesta declaró haber presentado algún tipo de AA. De estos, el 75,3% (n=140) refirió signos y síntomas locales tras la vacunación, el 9,7% (n=18), signos y s
