Pulmonary Fibrosis Statistics

With nearly 2.0 million IPF deaths recorded globally in 2019 alongside an annual UK estimate of 5,047 new cases, this page connects real incidence and survival realities to what changes in practice, including treatment patterns, functional decline, and cost and QALY value. Expect sharp contrasts such as antifibrotics linked to slower 6 minute walk deterioration and reduced FVC loss alongside guideline progression thresholds and multidisciplinary diagnosis habits that help explain why outcomes vary so widely.

Pulmonary fibrosis is still one of the deadliest interstitial lung diseases, and the Global Burden of Disease study estimated 1,999,700 idiopathic pulmonary fibrosis deaths worldwide in 2019. At the same time, real world antifibrotic use and measured outcomes create a sharper picture than survival alone, from functional decline on the 6 minute walk test to slower forced vital capacity trajectories. This post pulls together the key IPF statistics so you can see where risk, treatment impact, and economic burden line up across countries and care settings.
