DIRAE study: Seasonal allergic rhinitis distribution in Spain

Background: National epidemiological study to observe if among patients with pollinic seasonal allergic rhinitis (SAR), there are differences between those visited by primary care physicians (GPs) or allergists (ALs). Methods: 758 and 739 adults were recruited respectively by GPs and ALs. The physicians filled in a questionnaire: ARIA classification, prescribed treatment, and asthma incidence. The patient completed a visual analogical scale (VAS) to evaluate the severity of the rhinitis. Rhinitis control (controlled, partially controlled, and not controlled) was assessed by physician and patient. Results: No significant differences were found among patients visited by GPs or ALs concerning the ARIA classification and rhinitis severity. Treatment with oral antihistamines was 92.3% and 89.3% for GPs and ALs, respectively. The use of nasal corticosteroids was 76.7% and 60.4% for GP and AL patients, respectively. 31.9% of the patients visited by the ALs were treated with immunotherapy. The use of alternative medicine was 10.9% and 7.6% in GP and AL patients, respectively. The perception of “controlled” rhinitis was similar among patients (40.0%) and doctors (40.1%), although patients referred differences depending if they were visited by GP (44.8%) or AL (34.9%). Asthma prevalence was higher in those who suffered persistent as compared to intermittent rhinitis (OR=1.81, 95% CI: 1.39–2.36, p<0.001), and moderate/severe vs. mild rhinitis (OR=1.68, 95% CI: 1.05–2.68, p=0.029). Conclusion: The patients with pollinic SAR visited by GPs or ALs show no differences in severity. Less than half of the patients can be considered as “controlled” (AU)
