Improving allergy management and treatment: a proposed algorithm and curriculum for prescribing allergen immunotherapy in the primary care setting

Abstract

Allergic rhinitis (AR), a condition characterized by sensitivity to allergens leading to poor quality of life, including disrupted sleep, reduced vitality, lowered mood, changes in blood pressure limited frustration tolerance, impaired focus, decreased performance in academic and professional settings, and millions of missed work and school days every year. Approximately 20–40% of individuals in the United States are affected by AR, which carries notable clinical and financial burdens. Interestingly, there is a strong link between AR and asthma to the extent that countries with a high prevalence of rhinitis have asthma rates ranging from 10% to 25%. Research has indicated that Allergen Immunotherapy (AIT) is associated with improved AR symptoms, a potential to resolve the AR over time, a decreased likelihood of asthma exacerbations and incidence of pneumonia in individuals with concurrent asthma, which are advantages that persist for years even after the cessation of treatment. Although patients presenting with allergies are first seen and treated in the primary care setting, gaps in training and the lack of available guidance for primary care practitioners have significantly impacted the quality of care for these patients with persistent AR symptoms, resulting in inefficient use of healthcare resources. To complicate matters, there is an insufficiency of allergists and immunologists, impacting the capacity to provide next-level care to the number of AR patients who could benefit from AIT. Hence, there is a critical need to equip primary care providers with educational experiences on essential concepts related to immune responses in allergies and asthma, recognizing the significance of the common airway in treating these entities and familiarization with the scientific evidence supporting various options for AIT. The development and implementation of medical education and algorithms designed to assess diverse patients’ symptoms, pharmacotherapy approaches, and situations where AIT can be initiated or sustained are warranted. The present commentary proposes a workflow model of the critical steps for managing and treating mild to moderate respiratory allergies via AIT in primary care settings. In addition, the initial development of medical education programs to minimize the burden on allergy-specialized care while, importantly, actively improving patient outcomes will be discussed.
