Background:
Over the last 10-20 years, international guidelines and consensus statements for the management of common allergic diseases (e.g. allergic rhinitis and asthma) have been developed and disseminated worldwide. However, their impact on knowledge and standard of clinical practice among primary care physicians and specialists is unknown.
Objective:
To investigate need for an improvement in the dissemination of international guidelines for the diagnosis and management of allergic rhinitis.
Methods:
Seven medical students who attended 3-day 1st International Basic Allergy Course (2010) took down all questions raised during the entire course. A systemic analysis of these questions was performed to identify areas for improvement in diagnosis and management of allergic diseases mainly in the Association of Southeast Asian Nations (ASEAN) region.
Results:
268 participants, 143 males and 125 females, comprising Ear, Nose and Throat (ENT) specialists (n = 106) and trainees (n = 34), general practitioners (n = 87), and other healthcare professionals (n = 41) attended the course. Of the 103 questions recorded, 59 were regarding treatment modalities in allergy practice such as immunotherapy (n = 38), pharmacologics (n = 15), nasal surgery (n = 2), and others (n = 4). 41 questions (39.8%) have answers based in the Allergic Rhinitis and its Impact on Asthma guidelines (2001 and 2008). Certain questions were selected for further analysis because they appeared to be (a) more commonly asked (e.g. immunotherapy) or (b) were deemed to be challenging or, even controversial (e.g. food allergy and differential diagnosis between vasovagal and anaphylaxis reaction), as the recommendations in current international guidelines were less well-defined.
Conclusion:
Our study identified several problems that, if tackled, could help minimize confusion and provide better care for patients suffering from allergic diseases especially in the ASEAN region.
