Summary

Chronic cough is a common and burdensome condition in children, with complex and overlapping etiologies that often lead to delayed diagnosis, misdiagnosis, and inappropriate treatment. This prospective, controlled, observational study aims to develop and clinically validate a Wenjuanxing-based, parent-reported, multidimensional etiologic screening questionnaire for pediatric chronic cough. Children aged 3-18 years presenting with cough lasting ≥2 weeks will be enrolled in a tertiary pediatric respiratory clinic and allocated to either a routine-care group or a questionnaire-assisted group. All caregivers will complete the standardized electronic questionnaire, which generates an automated preliminary etiologic suggestion based on symptom patterns, triggers, and associated features. Diagnostic accuracy, treatment effectiveness, and symptom resolution will be evaluated through structured follow-up at two weeks. The primary outcome is the difference in diagnostic accuracy between physicians using routine assessment alone and those supported by the questionnaire. Secondary outcomes include treatment response and prevention of cough chronicity. This study seeks to provide evidence for a scalable, digital, and standardized screening tool to improve early etiologic identification and clinical decision-making in pediatric chronic cough.
