ERN-LUNG has conducted a network-wide survey, on the use of PROs. While the use of PROs is mandatory in the UK, it remains of disparate use in the EU. We are in the process of analyzing the results (also with regards to each different Core Network), but we can already announce that around half of the responding clinicians use PROs. We will give more information on the survey and on the steps that ERN-LUNG will take to promote the use of PROs in the next Newsletter!
