A controlled study of education for improving compliance with cromolyn sodium (Intal): the importance of physician-patient communication

Abstract

The effectiveness of an educational program to increase compliance with cromolyn sodium was assessed in 31 children and adolescents 6 to 17 years of age. Patients were randomly assigned to an education or noneducation group. A standard education program regarding asthma and asthma medications was provided to the education group during four monthly visits. At each visit, all patients were assessed in terms of knowledge of asthma and medications, asthma-related symptoms, and pulmonary function. Patients were also asked to self-rate their compliance. The education program increased the patients' knowledge of cromolyn, and appeared to result in increased cromolyn compliance. Post-hoc analyses, however, suggested that increased compliance did not correspond to improved medical status unless the quality of management (by physician and parents) of the child's asthma was taken into account. These results suggest that inadequate management of asthma in children may be a more serious problem than patient noncompliance.
