Detailed description
Asthma remains a serious health problem with increasing prevalence and incidence. There is limited information about severe asthma among Chinese pediatric patients. In this context, we decided to explore the clinical characteristics and risk factors of severe asthma in children. This is a descriptive, observational, retrospective cohort study in children with asthma. The purpose of this retrospective study is: to determine the clinical characteristics of severe asthma of children; to identify the factors associated with severe childhood asthma. Participants were consecutively recruited from asthma clinics between January 2021 and December 2021 at Children's Hospital of Fudan University. Patients fulfilling the following criteria were eligible for inclusion: (1) aged 6-17 years old; (2) diagnosed with asthma according to the Global Initiative for Asthma (GINA) 2020 guideline; (3) children and their caregivers are informed and voluntarily join the database and had follow up for at least 1 year. Patients who had cystic fibrosis, mechanical airway obstruction, or any other pulmonary disease or whose parents or legal guardians were not able to fill in the questionnaires were not enrolled. At baseline, the asthma specialist questioned each of the patient in the presence of their caregivers to ensure that they supplied accurate disease information and were included according to the criteria. The patients and their caregivers are asked to complete the online questionnaires including the demographic; baseline asthma control, triggers, exacerbation, medication and adherence; environmental exposure, and diagnosis and control of comorbidities, etc. If a patient had poorly controlled comorbidities, multidisciplinary consultation would be recommended. Clinical assessments were arranged at baseline, 3, 6, 9, and 12 months.
