New questionnaire aims to spot hidden lung damage in COPD patients
NCT ID NCT07374172
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is refining a questionnaire to help doctors detect small airway dysfunction in people with COPD. Researchers will also compare two breathing tests (spirometry and oscillometry) to see which works better in primary care. About 108 adults with asthma, COPD, or both will take part. The goal is to make diagnosis easier and more accurate for everyday clinics.

Who is studied
The study population for the SCOOP study will consist of patients referred by their General Practitioner (GP) to the Asthma/COPD service. Patients can be referred by their GP when they are suspected to have asthma, Chronic Obstructive Pulmonary Disease (COPD), asthma-COPD overlap (ACO) or when they present with pulmonary symptoms of unknown origin. After referral by the GP, patients will be invited by the Asthma/COPD service. Both patients invited for an initial diagnostic visit or a control visit can participate in the SCOOP study.
