Cobertura de vacunación antigripal en niños con condiciones de riesgo en Cataluña / Influenza vaccination coverage in children with risk conditions in Catalonia

RESUMEN

INTRODUCTION: Influenza vaccination is recommended in Catalonia in children older than 6 months with risk conditions for developing flu-related complications. The aim of this study is to determine influenza vaccine coverage in children with risk conditions and their association with socio-demographic factors and medical variables. MATERIAL AND METHOD: Descriptive cross-sectional study of children with risk conditions for developing influenza complications (aged between 6months and 15years old) assigned to Primary Health Care centers in Catalonia at the beginning of the 2011-2012 influenza vaccination campaign. The information on vaccination status and study variables were obtained from data registered on electronic health records by primary care teams. The relationship between influenza vaccination and demographic and medical variables was analyzed using bivariate analysis and a multiple logistic regression model. RESULTS:Influenza vaccination coverage was 23.9%. Variables associated with influenza vaccination were age 2years or older (aOR 1.6 [1.4-1.7] in children 3-5years old; 1.8 [1.7-2.0] in those 6-10 years, and 2.2 [2.0 -2.4] in children ≥11years]); male sex (aOR 1.1 [1.0-1.1]); foreign nationality (aOR 1.2 [1.2-1.3]); age-appropriate immunization according to the systematic immunization schedule (aOR 3.3 [2.8-3.8]); more than one visit to the primary care physician (5 or more visits) (aOR 4.1 [3.8-4.4]), and more than one risk condition (3 or more conditions) (aOR 2.5 [1.6-3.9]). DISCUSSION: Compared to other countries, influenza vaccination coverage among children with risk conditions is low in our study. Strategies to improve coverage should be implemented
