To be eligible to participate in the registry, patients must be aged ≥40 years with a diagnosis of IPF confirmed at a tertiary pulmonary care centre according to current international guidelines within 3 months of the registry enrolment date. At patient enrolment, each site investigator will complete an investigator assessment form recording the diagnostic category most supported by the cumulative clinical data (definite IPF, probable IPF or possible IPF according to American Thoracic Society/European Respiratory Society/Japanese Respiratory Society/Latin American Thoracic Association definitions based on High-resolution computed tomography patterns and surgical lung biopsy results1 (

Exclusion criteria include malignancy, other than skin cancer, within the past 5 years; being on a lung transplant waiting list or participating in a randomised clinical trial at the time of enrolment. Patients enrolled in a non-interventional registry are eligible for inclusion, and patients may enter a randomised clinical trial after enrolment in the IPF-PRO registry.
Physicians at the enrolling sites will be instructed to approach every eligible patient receiving care at their clinic about participation in the registry and to document reasons for non-participation. As IPF-PRO is a non-interventional registry, enrolled patients will receive usual care for IPF as defined by the treating physician.
