The National Asthma Education and Prevention Program NAEPP Guidelines include recommendations for history-taking and discharge planning during an asthma visit, but there are no tools to measure performance. The objectives of this study were to define and operationalize key elements of history-taking and discharge planning, to develop a tool for measuring these elements, and to evaluate the quality of history-taking and discharge planning in the emergency department (ED) during visits for asthma using the new tool. Expert opinion and extensive literature review were used to develop a 13-item checklist containing items that should be documented during history-taking and provided during discharge planning for an ED visit for an acute asthma exacerbation by children. ⋯ Based on expert ratings, the checklist for measuring elements of history-taking and discharge planning during asthma visits appears to have considerable face validity. In the visits studied, the overall performance of these elements was low. Interventions to improve performance on the checklist might lead to improved care for children with asthma who frequent the ED.

This study tested the hypothesis that cough frequency during induced airway obstruction in children and adolescents with asthma relates significantly to other symptoms. The second hypothesis was that cough during remission may often be a conditioned or voluntary response. In experiment 1, tracheal sounds were recorded from 30 participants with asthma during a histamine challenge test. ⋯ During experiment 2, the cough percentage increased from 52% to 69% in asthmatics, and from zero to 57% in controls. It was concluded that cough in asthma is not diagnostically useful for assessment of airway obstruction. Excessive baseline cough among asthmatics could be the result of acquired responses to anticipated exercise-induced symptoms.
