I understand the philosophy behind federated research and so but there are use-cases where we need to extract the patient level data and use it ther softwares. I just tell you one: we have a large national ehealth database containing financial data about a patients (prescriptions, diagnosis), but not containing lab test results or other clinical data. We cannot download this financial database because of data protection reasons but if we have an own database, we can connect them togther and analyse it in a secure “environment” with approved softwares. So, if I have cohort and I want to analyse the LDL levels form my HIS and drug usage together I need to send the patient level data to them, they connect it with the prescription database and I can analyse it. That’s why we need patient level data sometimes. What do you think about this?
