Functional Status and Its Impact in Adults With Interstitial Lung Disease The SUNSET Longitudinal Study

What this Trial Is About

Researchers are studying people with interstitial lung diseases ILD to understand how their ability to perform daily activities, called functional status, changes over time. The study aims to explore what causes declines in functional status, evaluate tools that measure this ability, gather patients perspectives through interviews, track progression over two years, and develop a combined index to predict mortality. ILD causes lung inflammation and scarring, leading to breathing difficulties and muscle weakness that affect daily functioning and quality of life. This observational study includes several tasks first, validating functional status measurement tools with assessments at baseline and one week later second, conducting interviews to capture patient experiences third, tracking functional status and health outcomes every six months for two years aligned with routine appointments and finally, using collected data to create a multidimensional index predicting mortality. Assessments involve physical tests, questionnaires, interviews, and clinical data collection. Participants will be involved in about 90-minute sessions for each assessment at designated hospitals. Researchers will collect data on muscle strength, physical activity, symptoms, quality of life, hospitalizations, and mortality. The primary outcome is measured by the Short Physical Performance Battery at multiple time points. Safety and health status are monitored throughout, with data analyzed to understand functional decline and its impact in ILD over time.
