Clinical Trial Summary

Study Participants: Suspected asthma population, defined as individuals whose score of asthma screening questionnaire used in ECRHS study exceeds 0 and whose age is 35 and above. Intervention: Within the intervention arm, we have constructed a population-based pay-for-performance mechanism to encourage medical practitioners to care for population health. For study participants in the intervention arm, we will ask them to finish an online ECRHS questionnaire with notification of his or her suspected asthma status. Individuals whose score of ECRHS asthma screening exceeds 0 will be given a face-to-face survey, simple physical examination, pulmonary function tests, and provide a multi-component intervention at baseline. For suspected asthma population in the intervention arm, we provide community-based spirometry pulmonary function test (PFT) and education; If individuals whose FEV1 improved by ≥12% and ≥200 mL following bronchodilator administration with 400 ug salbutamol, they will be spirometry-defined undiagnosed asthma patient and will be encouraged to seek treatment and medication to the superior hospitals. Additionally, we provide (1) two digital health intervention programs to smokers and individuals with mental health issues; (2) CBT-based health education for study participants with abnormal BMI; (3) active recruitment into National Essential Public Health Program in China for those with abnormal blood pressure and blood glucose. Intensive follow-ups will be conducted at month 3 (telephone interview), month 6 (face-to-face with full steps of physical examination), and month 12. Comparison: Those who are assigned in the control arm, we will ask them to finish the same ECRHS online questionnaire with notification of his or her suspected asthma status and a face-to-face survey. No physical examinations, community-based pulmonary function tests will be given. Outcomes: The primary outcomes are asthma knowledge, lung function testing, and ACT score at month 12.
