ILD is a complex and heterogeneous disease, which is a major challenge faced by respiratory specialists and even internal medicine doctors. The diagnosis and differential diagnosis of ILD are relatively complex, with individualized treatment plans that require the participation of multiple disciplines including respiratory and critical care medicine, rheumatology and immunology, radiology, pathology, and rehabilitation nursing. In order to further promote the standardized diagnosis and treatment of interstitial lung disease, strengthen the standardized diagnosis and treatment management of ILD, improve ILD diagnosis and treatment capabilities, and enhance ILD diagnosis and treatment talent training, the Western Interstitial Lung Disease Special Committee of Chengdu High tech Medical Association successfully held a grassroots tour of the Western ILD Special Committee (Suining Station) on August 17, 2024, inviting several well-known experts from the western region to participate in the meeting and conduct case discussions.
