RESUMO
Background: Diagnosis, classification, and treatment of allergic rhinitis (AR) varies considerably despite the availability of treatment guidelines. Objectives: We aimed to carry out a two-part modified Delphi panel study to elucidate global expert management of AR in real life. Methods: The modified Delphi panel study was composed of two ten-minute online questionnaires sent to global AR experts, aiming to identify areas of consensus (defined as >75% respondent agreement) on aspects of their real-world daily practice related to AR diagnosis, classification, and pharmacotherapy. A workshop discussion with respondents held after the first-round questionnaire informed the development of the second-round questionnaire. Results: Eighteen experts (from 7 countries across 3 continents) completed both questionnaires in September-October 2021 and January 2022, respectively. The majority of respondents agreed that diagnosis of AR is best confirmed using a mixture of observation and testing (n = 15) and collaborating with colleagues across other specialties (n = 14). Experts agreed that severity (n = 18), upper/lower respiratory tract involvement (n = 15) and symptom frequency (n = 14) are important factors when classifying AR, however consensus was not reached on which classification tool should be used. Although there were mixed opinions on the preferred pharmacotherapy treatment in the presented case studies, respondents largely agreed on which treatments require less monitoring (intranasal corticosteroid therapies [INCS]) and when treatments should be stepped down (≤3 months). Although opinions varied across respondents, some respondents considered as-needed INCS treatment and surgery to be viable treatment options. Conclusion: We identified clear differences between real-world practice and treatment guidelines related to the management of AR. Furthermore, we recognized differences among physicians concerning their clinical practice in the pharmacological treatment of AR. These findings highlight the need for greater research into the management of AR and further indicate there is still a major gap between treatment guidelines and daily practice, even among specialists, suggesting a need for local guideline adaptation and implementation plans.
