To the extent that the asthma morbidity so prevalent in children today is due to underdiagnosis or lack of appropriate treatment, schools are increasingly faced with the issue of defining their role in the care of children with asthma. This paper describes efforts to conduct schoolwide screening for asthma in an inner-city elementary school over the past two years. Screening methodology adopted for the project resulted in a simple and noninvasive approach for identifying children with current asthma in a school setting. While not as medically comprehensive as would be required to conclusively diagnose asthma, the simple screening approach proved efficient in identifying a population of elementary school children with a significant level of asthma morbidity. The paper discusses the effectiveness and feasibility of the screening efforts and proposes how such a screening program might be incorporated into the routine health activities undertaken at any elementary school.
