Design, Rationale, Methodology, and Aims of a Greek Prospective Idiopathic Pulmonary Fibrosis Registry: Investigating Idiopathic Pulmonary Fibrosis in Greece (INDULGE IPF).

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a chronic, fibrosing interstitial pneumonia of unknown origin. Despite the fact that the guidelines on the diagnosis and management of the disease were updated in 2015, incorporating novel agents recently introduced in the therapeutic approach of IPF, there is a lack of data on the epidemiology, disease status, and treatment in clinical practice. Contemporary data provided by national registries in IPF provide valuable information to guide clinical management of the disease in the real-world setting, adjusted to the local needs. OBJECTIVE: Investigating Idiopathic Pulmonary Fibrosis in Greece (INDULGE IPF) is a Greek observational registry aiming at gaining further knowledge on the characteristics, management, progression, and outcomes of patients with IPF treated under real-world, clinical practice conditions in Greece. METHODS: Approximately 300 patients will be enrolled consecutively in seven reference centers, constituting the largest IPF registry ever established in Greece. CONCLUSION: This registry is expected to provide data on the characteristics of IPF patients in Greece and the entire clinical management during the course of the disease.
