BackgroundMany asthmatic patients have coexisting allergic rhinitis (AR). This study aims to investigate the compliance of physicians with respiratory medicine specialty (PRMs) to Global Initiative for Asthma (GINA) and Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines during the management of their asthma-AR patients. MethodsThis cross-sectional questionnaire study surveyed the diagnostic methods and treatment patterns for asthma-AR comorbidity by PRMs from 98 hospitals across China. ResultsPRMs reported an estimated prevalence of asthma-AR comorbidity of >30% at their clinics. PRMs with greater work experience and a higher professional title estimated treating a significantly higher proportion of patients with AR within the previous month (p=0.002 and p<0.001, respectively); they also estimated a higher incidence of patients with AR in the autumn (p<0.001 and p<0.001). A higher percentage of PRMs with 11 years work experience prescribed nasal steroids for AR as compared to those with 1 to 10 years experience (56.9% vs 44.7%, p=0.002). A greater proportion of chief physicians used leukotriene modifiers and a lower proportion used antihistamine H-1-receptor blockers for AR as compared to residents (resident vs assistant chief: 27.5% vs 11.6%, p=0.002; and resident vs chief PRMs: 27.5% vs 9.5%, p=0.001). ConclusionPRMs in China demonstrated an up-to-date comprehension of asthma management (>90%); however, knowledge gaps existed in their concepts of AR and asthma-AR comorbidity. Thus, further education is warranted for PRMs regarding the importance of AR in asthma patients, definitive diagnosis (allergy tests), classifications of AR, and treatment guidelines for the asthma-AR comorbidity.
