Determining the Relative Burden of Childhood Asthma at the Local Level by Surveying School Nurses.

Schools are effective venues for providing pediatric asthma education programs. Resources are limited, however, so ideally, these programs should be provided to schools with the highest prevalence. National and state asthma surveillance data cannot be extrapolated to local geographic areas. The objective of this study was to survey local schools on Long Island to obtain this information. Survey forms were mailed to the school nurses at every school in Nassau and Suffolk Counties, New York, in 2004, 2006, 2008, and 2010 asking for the number of children with asthma and the number who had permission to access rescue medication in the school. School nurses completed and returned the forms. We analyzed data from elementary and high schools separately, as high-school students often carry their medications with them without obtaining permission. Of the 3,327 surveys sent, 2,060 (61.9%) were returned and 1,807 (54.3%) could be included in the analyses. Overall, asthma prevalence increased from 7.6% in 2004 to 8.7% in 2010. This mirrored the New York State and national trends, although the rates we found were generally lower. The rate of asthmatic children with permission to access rescue medication in school was about the same throughout the study period (39.7% in 2004 and only 42.3% in 2010). Both rates were lower in elementary schools in low socioeconomic areas. These methods allowed us to compare the burden of childhood asthma in individual responder schools in a relatively large geographic area.
