As the
prevalence and socioeconomic burden of
allergic rhinitis is steadily increasing every year, it is essential that clinical practitioners
diagnose and manage
allergic rhinitis in an evidence-based manner. Therefore, the Korean
Academy of
Asthma,
Allergy and Clinical
Immunology developed new
clinical guidelines for Korean
patients and practitioners. We first performed a
questionnaire survey to
address the core questions, about which clinical practitioners are the most curious. A large group of
physicians (
allergists),
pediatricians, and otorhinolaryngologists developed answers for those questions by performing a systematic
literature review and determining the appropriate levels of recommendation. In this article, we propose 11 answers for core questions regarding the
diagnosis and
differential diagnosis of
allergic rhinitis.
