Objective:To explore the effect of WeChat mini program in immunotherapy management of pediatric patients with combined allergic rhinitis and asthma syndrome (CARAS).Methods:Using the convenient sampling method, 101 children with CARAS who received sublingual immunotherapy in the First Affiliated Hospital of Zhengzhou University from January 2019 to January 2020 were selected as the research objects. The standardized management team of immunotherapy clinic was established. The newly developed specific immunotherapy Wechat applet was used to establish a new model of nurse-patient interaction and communication. The disease knowledge was regularly pushed, medication reminder, nurse telephone intervention and other standardized management were delivered through the Wechat applet to implement continuous nursing for children. The effects of this management model on medication compliance, rhinitis symptoms and asthma control were analyzed.Results:A total of 101 children were included in this study, 3 cases were lost to follow-up, and a total of 98 cases completed the study. After 12 months of intervention, the drug possession score of dust mite drops increased from (83.43±3.68) to (91.78±3.71), the symptom score of allergic rhinitis decreased from (5.83±1.32) to (1.94±0.98), and the score of asthma test questionnaire increased from (18.12±3.99) to (24.97±3.09), the proportion of children with complete control of asthma increased from 48.0% to 90.8%, and the proportion of children without control of asthma decreased from 10.2% to 1.0% (all P<0.05). Conclusion:The immunotherapy management of pediatric patients with combined allergic rhinitis and asthma syndrome based on WeChat mini program can effectively improve the compliance of children and their family, improve the control level of allergic rhinitis and asthma.
