Clinical Trial Summary

This study aims to evaluate the differences between patient's and their physicians' perception of quality of life and the effect of disease severity and co-morbidities. Patients and physicians will complete two sets of questionnaires at an initial clinic visit and again six months later.

Description:

Idiopathic Pulmonary Fibrosis is a progressive and debilitating disease characterized by progressive scarring of the lung parenchyma of unknown cause. In the US approximately 100,000 individuals have been diagnosed with this disease and the only cure available is lung transplantation. There have been two drugs approved by the FDA for treatment of IPF which have demonstrated the ability to slow disease progression but have no impact on quality of life.

Symptoms of IPF include shortness of breath, cough, and fatigue which all contribute to a decreased quality of life. Additionally, these symptoms and the need for supplemental oxygen use causes significant psychological and social impairment. Multiple questionnaires have been used to measure patient reported quality of life in both clinical and research settings. The King's Brief Interstitial Lung Disease (KBILD) Questionnaire is a disease-specific patient reported outcome measure and has been validated across several different patient groups and countries. Additionally, the EuroQol group has developed the EuroQol five dimensional 5-Level (EQ-5D-5L) questionnaire which is a non-disease specific assessment of health-related quality of life and has not yet been widely used in a population of patients with IPF.

Significant disparity between patient and physician perception of quality of life has been demonstrated across different disease processes. While there are many contributing factors to overall wellbeing the general assumption is that with more advanced disease quality of life predictably decreases. The investigators plan to test this hypothesis to better understand the complex relationship between chronic disease and quality of life in patients with IPF.

Eligibility

Inclusion Criteria:

• Patients with a multidisciplinary diagnosis of IPF according to the 2018 ATS/ERS/JRS/ALAT Clinical Practice Guidelines.

• All ranges of disease severity based on pulmonary function testing: forced vital capacity (FVC) and diffusing capacity (DLCO).

Exclusion Criteria:

• Any impairment or co-morbid disease that results in an inability to read or understand a questionnaire or provide informed consent. The study team member will make this determination according to their best clinical judgement.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Patient and Physician Responses to the Kings Brief ILD (K-BILD) Questionnaire	A comparison of physician and patient reported quality of life based on responses to the Kings Brief ILD Questionnaire (K-BILD). The domain and total score ranges are 0-100 where a score of 100 represents best health status.	6 months
Primary	Patient and Physician Responses to the EuroQol five dimensional 5-Level (EQ-5D-5L) questionnaire	A comparison of physician and patient reported quality of life based on responses to the EuroQol five dimensional 5-Level (EQ-5D-5L) questionnaire. The domain ranges are 1-5 and the total score ranges are 5-25 where a score of 5 represents best health status. The visual analog scale portion of the questionnaire ranges from 0 to 100 where a score of 100 represents best health status.	6 months
Primary	Patient and Physician Responses to the Raghu Quality of Life in Interstitial Lung Disease (RQ-LIFE-ILD) Questionnaire	A comparison of physician and patient reported quality of life based on responses to a novel visual analog scale questionnaire the Raghu Quality of Life in Interstitial Lung Disease (RQ-LIFE-ILD) Questionnaire. The domain ranges are 0 to 10 and the total score ranges are 0 to 50 where a score of 0 represents best health status.	6 months
