Study design details

Main study objective

To identify features of ILD MDTs associated with more accurate diagnosis of IPF with a view to improving diagnostic accuracy and patient stratification to optimise treatment outcomes worldwide.

Data analysis plan

Phase I analysis will be descriptive, comparing reported diagnostic practices by region, country economic status, and participant expertise. Phase II analysis will also be descriptive, with the use of agreement measures such as Cohen's Kappa statistic to explore diagnostic agreement. Diagnostic accuracy compared to the several different reference groups: the diagnosis of the clinican providing the case details, the diagnosis of an expert MDT with global representation, the diagnosis as indicated by available follow-up data.
