Abstract

Applications of National Asthma and Education and Prevention Program (NAEPP) guidelines for the diagnosis and management of asthma may reduce the morbidity of this disorder. Medical records and questionnaires from a series of 177 outer-city adolescents and adults with persistent asthma were audited according to NAEPP guidelines and for utility of salmeterol (Serevent®). Allergic sensitivity and exposure to indoor allergens house-dust mite (66% of patients), fungi (42%), cat (20%) and/or dog (14%) were of dominant importance to persistent asthma. Patients who continued salmeterol over 1 year had reduced severity of disease, improved forced expiratory flow at 25%-75% of vital capacity, and reduced usage of systemic, but not inhaled, corticosteroid.
