The National Chronic Subdural Data Hub (nCSDH) is an upcoming registry looking to understand how care is delivered for patients with a chronic subdural haematoma (cSDH) across England and Wales. The study is aiming to launch in Summer 2026. 

With a network of collaborators across neurosurgical and non-neurosurgical hospitals, the study will collect routine data on all patients diagnosed with a chronic subdural haematoma over the study collection period.
