Analysis of adherence and determinants of sublingual immunotherapy in patients with Artemisia pollen-induced allergic rhinitis

Abstract

Objective:To monitor adherence to specific sublingual immunotherapy （SLIT） in patients with seasonal allergic rhinitis（AR）, analyse factors influencing adherence, and provide research support to effectively improve adherence. Methods:Patients with AR who underwent Artemisia pollen SLIT at the Department of Otolaryngology-Head and Neck Surgery, First Hospital of Shanxi Medical University from May 2021 to April 2022 were retrospectively followed up by telephone to investigate the current status of treatment, count the causes of shedding, and extract relevant information from their medical record data for analysis. Results:Of the 112 patients surveyed, 34 discontinued treatment（30.3%）; patients who experienced adverse reactions and SLIT patients who had been on treatment for more than 6 months showed relatively good adherence（P<0.05）. The main reasons for discontinuation in patients who dropped out were: asymptomatic discomfort during the non-pollen phase and therefore discontinuation of treatment or feeling that treatment was ineffective 9 cases（26.5%）, forced discontinuation due to vaccination or pregnancy, or epidemics 6 cases（17.6%）. Conclusion:Long-term adherence of patients to Artemisia pollen SLIT still needs to be brought to the attention of healthcare professionals, especially in the early stages of treatment when good patient education and good channels of trust and communication between doctors and patients need to be established.
