Modelling of Quality Life, Clinical and Physiological Measures in Idiopathic Pulmonary Fibrosis

As there are no validated tools for assessing patient reported outcomes or health related quality of life in idiopathic pulmonary fibrosis (IPF), different studies have utilised different methods. This means that comparison of the outcomes of studies is difficult or inaccurate. By collecting different quality of life tools and patient reported outcome at the same time, it will be possible to map or model the results of one tool or groups of tools onto another. 250 patients with IPF will be asked to complete the EuroQoL 5D, Kings Brief Interstitial Lung Disease questionnaire, St George's Respiratory Questionnaire, MRC dyspnoea scale, University of California, San Diego shortness of breath questionnaire and the Hospital Anxiety and Depression Scale, along with spirometry every 3 months, and undergo a 6 minute walk test every 6 months, over a 12 month period. Prognostic models will be constructed from all the clinical (questionnaire and function) measures a linear regression model.
