✦ Synopsis

Within an epidemiological survey on Chronic Obstructive Pulmonary Disease, before reporting data on the prevalence of bronchial asthma we checked the group of subjects defined as "pathological" by means of a suitable questionnaire and a group of "normals" as a control. We evaluated the sensitivity and specificity of the questionnaire, in comparison with a clinical evaluation made by two physicians and controlled the relationship among their results, non-specific bronchial hyperreactivity and skin tests. In particular the correspondence between diagnosis made by physicians from a clinical evaluation and that obtained by questionnaire was not satisfactory. We suggest the importance of employing physicians for an epidemiological approach to asthma, in absence of a valid objective criterion.
