Idiopathic Pulmonary Fibrosis (IPF) is one of the most aggressive form of Idiopathic Interstitial Pneumonias and its clinical course is highly variable. Many tools have been used in past like pulmonary functional test (PFT), but none of them can actually predict the extent of disease. So there is unmet need of development of a tool which can predict the course of disease. Composite Physiological Index (CPI) on comparison with already established GAP model of IPF helps us to predict the course of the disease so that appropriate medical and surgical intervention like lung transplantation could be planned.
In this study mortality rate in IPF Patients were studied retrospectively for period of two years. In our study, it was found that mortality rate in IPF increases with increase of mean composite physiological Index, hence it indicates the poor prognosis of disease.
