Phone support to reduce hospital visits for severe COPD patients on home oxygen

This study is testing whether phone-based nursing support can help people with severe COPD (chronic obstructive pulmonary disease) who use home oxygen concentrators stay healthier and avoid returning to the hospital. If you're in the intervention group, a nurse will call you a few times over 3 months to answer questions about your illness, medications, and oxygen equipment, and to check in on how you're doing. The study wants to see if this extra support reduces hospital visits and improves how you feel.

People with severe COPD who use home oxygen often end up back in the hospital, which can be stressful and costly. This trial is testing whether regular phone support from a nurse — answering questions and providing guidance — can help prevent those readmissions and improve daily life.
