An international medico-economic survey of 2007 children with recurrent nasopharyngitis and acute otitis media. Preliminary bindings.

The terminology used to describe upper respiratory tract infections (URTIs) in children can be based on the symptomatic picture, the aetiological agents or anatomical features involved, or classical disease descriptions. However, there is a lack of precision in the epidemiology and nosology of nasopharyngitis and acute otitis media (AOM) in children. Moreover, there are differences between European countries in diagnostic and therapeutic measures. The aim of this broad survey was to record all items potentially relating to URTIs in children and, therefore, to refine the classification of nasopharyngitis and AOM, as well as to clearly define their medical and economic consequences as observed in normal medical practice. Specifically, the objectives can be summarised as follows: to define nasopharyngitis as a clear-cut entity and thus provide a standard for clinical trials; to identify different definitions of AOM and compare them with Paradise's algorithm; to establish a profile of patients at risk of recurrences; to assess therapeutic habits; and to determine the cost of illness. The survey involved 328 European physicians (general practitioners, paediatricians, ear, nose and throat specialists), who recorded spontaneous medical visits of 2007 children presenting with a first episode of nasopharyngitis or AOM during November and December 1996. These children were then followed up until April 1997 so that any recurrent episodes could be recorded. A parent questionnaire focusing on burden of illness for the family was also included. Demographic characteristics at inclusion and the first data on the multifactorial correspondence analysis for nasopharyngitis at inclusion are available and have been presented.
