Chronic Respiratory Disease

Asthma and COPD are common chronic respiratory diseases with substantial global mortality and hospitalisation burdens. Primary-care diagnostic uncertainty is a rationale for a unified modelling strategy across asthma, COPD, and combined cohorts. Comorbidities are central contributors to hospitalisation burden in chronic respiratory disease. Patients with asthma-COPD overlap tend to have more comorbidities, exacerbations, and hospitalisation risk than patients with either disease alone.
