PLOT-ICH is a new international, prospective, observational study on spontaneous intracranial haemorrhage. We aim to form a network of researchers across the world, to map the care of ICH patients globally and understand differences in patient presentation, disease management and outcomes.

Any hospital worldwide

All hospitals managing patients with spontaneous intracranial haemorrhage can participate. Each hospital will form a local team responsible for local study set up and data collection.

Choose a 30-day study window

Each hospital will choose a 30-day study window to collect data. All patients admitted to your hospital with a diagnosis of intracranial haemorrhage during the chosen study window will be included.

Collaborative authorship

Multiple teams of collaborators will work together across the world in this study. All collaborators will be eligible for authorship using the collaborative authorship model.
