Immunotherapy has been used for the treatment of allergic rhinitis since the turn of this century. The purpose of this study was to assess the compliance with immunotherapy in a medical center. The charts of 315 patients aged 5 to 18 years, who were prescribed immunotherapy for treatment of allergic rhinitis for at least 1 year before the study, were selected by computer and reviewed. The first analysis consisted of using a log-linear analysis in order to investigate the relationship between source of payment (private or nonprivate), gender, and race. All main effects and interactions were entered into the model (P < .01). The second analysis consisted of using a log-linear analysis to investigate the relationship between the presence/absence of pollen, mold, mite, and animal IgE antibodies, and compliance (model, P < .05). Two hundred fifty-eight patients were private and 57 were nonprivate. Fifty-nine percent (n = 152) of private patients and 46% (n = 26) of nonprivate patients were compliant. Of the 315 patients with allergic rhinitis, 52 also had asthma and 34 had atopic dermatitis. Sixty-one percent of the asthmatic patients and 47% with atopic dermatitis were compliant. Compliance was not increased by the number of allergens to which a patient was allergic. Males were slightly more compliant than females, caucasians were more often private patients and non-whites were more often nonprivate patients. Private patients were more complaint with immunotherapy than nonprivate patients.
